  1. My apologies for the delayed response. Can you try accessing the slideshow here: http://smilebox.co/1wSxqNM. If that doesn’t work, please let me know. Thanks!

  2. Hi Dr. Hohenhaus, I am looking back at the article you did on my african grey-scarlett entitled “SAVE Saves a Bird. I am not able to get her photo gallery to work and the smilebox?does not come up, just some ad and no photos. Can you help me? Sharon Parker

  3. You’re welcome! Thank you for sharing Scarlett’s story!

  4. Hi Dr. Hohenhaus! The work you did to share Scarlett’s experience was extraordinary. Thank you so much for telling her story and adding her video and photo gallery. I have at least 100 photos of her very special artwork where nothing is just thrown somewhere but there is thought and vision in all the work she does . It is amazing to watch her create. Thank you for saving her life Dr. Quesenberry and again, Dr. Ann H. for working so hard to portray a wonderful life-my beautiful Scarley! Sharon

  5. David,

    Myelofibrosis is a disease of unknown cause. It is not considered cancer, but a myelo- (meaning bone marrow) proliferative disorder. It is quite uncommon in pets and optimal treatment has not been defined. In humans, MPD are often treated by oncologists as chemotherapy is sometimes used to treat the disorder and in some cases MPD progress to cancer. Progression to cancer is extremely rare in dogs. Here is a link to information about MPD from the National Cancer Institute:

  6. Dr. Hohenhaus:

    I have a 10 year old whippet named Buddy who has over a 4 to 6 week period became lethargic and now has severe anemia. Our local veterinary hospital has worked with another larger vet hospital to diagnose him with myelofibrosis. We are on a course of prednisone and cyclosporine. Our specialist did not refer to this as a cancer, but other citations do call it a cancer? Are there other options for treatment for this disease? Thank you for your time.


  7. Jennifer,

    I am sorry for the loss of your dog. While I am concerned about public health and the health of companion animals, I am not a public health specialist and must defer questions like yours to the experts. It sounds like you have contacted the appropriate experts and if they are not concerned, then I feel I cannot add more to the conversation.

    If you are interested in further information about this topic here are some reliable internet resources:

    Hi Dr. Hohenhaus,

    My name is Jennifer and I live in Hawaii. I was hoping you might be able to help me.

    In November 2011, I took my healthy dog to the Vet. He is given a drug (even though an earlier blood test showed he could not tolerate) that caused a side effect – skin lesions. The lesion got infected and spread yet the Vet refused to take a Culture & Sensitivity test and just prescribed different antibiotic, 4 to be exact. He told me that my dog must have a fungal infection but to continue giving him the antibiotics.. To make a long story short, when a test was finally done, it showed he had 5 organisms, MRSA, STREP GROUP A, PSEUDOMONAS, ESCHERICHIA COLI, and KLEBSIELLA PNEUMONIAE.

    Both the MRSA and STREP were found to be RESISTANT to ALL antibiotics. Because of the non-judicious use of antibiotics and many lost opportunities to properly diagnose the infections, my dog endured horrible pain and discomfort for over 5 months (see photos). He was not going to survive so we had to put him down.

    Over those 5 months, the Vet/Clinic told us that there was no need to take any extra precautions (no gloves or gowns needed when treating the dog) and they even had us stay in the waiting room with other humans and animals AFTER he was diagnosed. The Vet actually took a culture while we were in the waiting room!

    Despite all 5 bacteria, they insisted he was NOT contagious. (I did try to find another vet but each one I contacted refused to see my dog and said they did not want to get involved…)

    A few weeks after my dog was diagnosed with all 5 bacteria, I got sick with STREP A and another one of my dogs got a UTI STAPH infection.

    I have contacted every organization (both State & private), even contacted the Dept. of Health, the Hawaii Vet Board, the State Vet and even the Federal Vet and the media. No one felt it was in the least bit important. Should anybody be concerned about public health and the companion animal population besides me?

    Ironically, when I tried to inform the public concerning MRSA and pets, I was threatened with a lawsuit by the Animal Clinic.

    From what I have read and experienced, indiscriminate antibiotic use in veterinary medicine poses significant human health implications. Yet, it seems I am more concerned than anyone else including the people and organizations that may be able to control it. Is my concern valid or am I overreacting?

    Thank you so much for your time, I really appreciate it.

  9. Mr. August,

    I am so sorry you cat is sick. I think Palladia may be an option for Homer, but most general vets are not familiar with its use. You are lucky since California is full of veterinary cancer specialists. Ask your vet which oncologist in your area is the one he usually works with and have him help you set up an appointment.

    Hi Dr. Hohenhaus,

    Happy New Year! Unfortunately, my 11 year old male Abyssinian Homer was recently diagnosed with Squamos Cell Carcinoma. I understand that the prognosis is not good, and surgery is not an option (the tumor is located in his upper jaw). He is still very much himself for the most part (hunting, eating, playing, etc) but I know that this can develop extremely quickly.

    I came across you while trying to research the drug Palladia as a potential source of treatment. I saw that you had done extensive research on toceranib phosphate in cats and was curious if you thought it might be worthwhile mentioning to my home veterinarian in Sacramento, CA. I understand that you while you may not be able to give any advice w/o seeing Homer, you might be able to let me know a bit more about the drug.

    Thank you very much for your time and for any suggestions.

  11. Veterinary dentists do not recommend awake dental scaling. It cannot address the space under the gums, the space between the teeth and the side of the tooth against the tongue. There is also a significant risk of injury to both the dog and tooth cleaner.

    I suggest you get the opinion of a veterianry cardiologist to assess the severity of heart disease and the risk of anesthesia. In dogs who have had heart failure, veterinary cardiologists recommend dogs be evaluated every 3 or 4 months, so it is probably time for Kkami to get another check up. Glad he’s doing so well.

  12. Linda says:

    Dear Dr. Hohenhaus,
    I have Kkami, a 14 years-old yorkie. He was dignosed with heart failure in May 2011 and has been on Enalapril since then. When he was dignosed, the vet said he will live for about 6 months, but he is still alive without any worsened symptom and also eating and drinking well. His dental condition is very very bad because the vet advised against putting him under anesthesia for dental cleaning. He doesn’t chew gums and doesn’t let me brush. The only thing we are using is the anti-tartar drops in his water. Now I am researching about anesthesia-free dental cleaning. Please provide an advice for me and Kkami. I appreciate your care.

  13. Joanne McMillen says:

    Dr. Hohenhaus,

    Thank you for the information!.

  14. I have no new information on that drug at this time. I seem to remember talking with the researchers and learning there was an obstacle to continuing the line of research. The newest drug approved for dogs with cancer is Kinavet, which is a tyrosine kinase inhibitor, similar to palladia and also approved for use in mast cell tumors. I hope this information helps.

  15. Joanne McMillen says:

    Thank you for your reply — do you have any idea what the status is since I am having trouble finding information dated later and 2009. How is possible that something that seems so promising seems to have no information. Are there any new cancer drugs (I know about palladia) for dogs that you are aware of? Thank you.

  16. No, it is not available for dogs as yet.

  17. Joanne McMillen says:

    Is nitrosylcobalamin available yet for dogs –I have searched and cannot find any updates on this drug since 2009.

  18. I am so sorry your dog is sick. Hemangiosarcoma is a very difficult tumor to treat and you should consult an oncologist.

    To my knowledge, there are no proven holistic therapies for hemangiosarcoma and you should consult a specialist in holistic therapies for more information.

  19. Hello Dr. Hohenhaus,

    My 9 yr old, little (9lb) Papillon had his spleen removed in an emergency surgery. The biopsy results that it was Hemangiosarcoma. The surgeon said the liver looked okay, visually, but of course this is an “incurable cancer”. I am consulting with a Oncologist, however, i wanted to see what your opinion was regarding any holistic treatments I can try. I appreciate anything you can help me with, I am not ready to lose my little one, we are extremely bonded he has been my constant companion for 9 yrs
    thanks much

  20. It sounds like your veterinarian has made a good start on managing your dog’s cancer. I would ask him/her if there is an oncologist available for consultation about the need for further treatment. If your veterinarian does not have an oncologist they work with on a routine basis, you can find one at http://www.acvim.org. Click on find a specialist.

  21. Harold says:

    Hello Dr. Hohenhaus,
    I have a small 11 yr old mixed breed dog who recently had a “small 0.2cm tumor removed from her 2nd to last right side breast upon immediate discovery. The biopsy came back as “Solid mammary carcinoma, intermediate grade.” Though the rest of the report aside from general discussion seems to be positive, I am very fearful, because of possible spreading of cancer throughout her body. it does state to have been completely excised, and my dog remains the same very active playful dog. Nevertheless, ‘m very concerned and wondered if from you experience is additional surgery needed in this case. Additionally, what is the likelihood that my dog may have spreading of this form of cancer throughout her body? I greatly look forward to any response and recommendation you may have.

  22. Tammy,

    I don’t know of any study addressing your question of once versus twice a year mating and the risk of mammary gland cancer. The following link will take you to a blog discussing the available information about mammary gland cancer. https://amcny.wordpress.com/2011/10/20/breast-cancer-awareness-for-pets/

    Thanks for reading Fur the Love of Pets!

  23. Tammy Lindsay says:

    Dear Dr Hohenhaus

    In Australia, the canine animal welfare organisations are currently considering bringing in a new law which will prohibit breeding from a bitch on more than one occasion per calendar year.

    Naturally this proposal is very unattractive to breeders. However, more importantly is the detrimental impact this proposed law could have on the long term health of the animal. I was advised by our vet to spay our Kelpie bitch as soon as possible because the longer we left her unspayed, the greater the risk of mammary cancer later in life. What I would like to do is provide the people who are drafting the new legislation with any available research on this issue. Are you able to direct me to any such research? Do you agree that if a bitch which ordinarily comes on season twice a year missed every second one, she will have a greater risk of mammary cancer than if she was joined every season.

    I appreciate any help you can provide.

    Many thanks
    Tammy Lindsay

  24. Lee Q. says:

    Thank you for your reply.

    Unfortunately, we have been given very little hope of success for having the tumor completely removed – even with amputation – due to the extremely aggressive nature of the manner in which injection site fibrosarcomas spread.

    We could not have gone through with amputation. Our cat is on the portly/rotund side and we foresaw a difficult recovery and poor quality of life with him on three legs.

    This has been very difficult for us. What can we do keep him pain-free/comfortable & how will know it is “time”?

  25. Lee,

    The study is no longer active and the results were not published. Depending on the ability of surgery to completely remove the tumor, amputation has a chance to cure your cat and may not require follow up radiation therapy. As difficult as it would be, you should really consider amputation.

    Here is a story about a dog with an amputation written last year; he is still alive and well. http://blogs.webmd.com/pet-tales/2010/11/how-many-specialists-does-it-take.html

    Here is a link to an online community for tripods. http://tripawds.com/

    I realized these are about dogs and you have a cat, but cats undergo amputation much less often than dogs and I don’t know of any cat specific resources. Cats, because they are lithe and light, do very well with an amputation, better than dogs, who do quite well.

  26. Lee Q. says:

    Hello Dr. Hohenhaus,

    Have a question about the treatment study “Comparison of Tumor Response to Radiation Therapy Alone with Radiotherapy Plus an Adjuvant Hemoglobin-Based Oxygen Carrier Radiotherapy Sensitizer, and Follow-up Assessment after Surgery and Chemotherapy.”

    Is this study still active? If so, would our cat be a candidate? He has an injection site fibrosarcoma, caudal aspect of right scapula/right lateral thorax, mild creatinine elevation; BUN with within normal range (stable). He has been biopsied and scanned (CT). Oncologist/Surgeon say tumor would likely return with surgery alone (we cannot afford radiation) and have recommended amputation. We do not want that for our cat and are heart-sick over what to do for him. If the study has been completed where can we go to read the results? Are there any other current sarcoma treatment studies/clinical trials?

  38. The most important part of managing mast cell tumors is wide surgical excision. It will take about 2 weeks for the incision to heal and then you will be ready to travel. Be sure to have your veterinarian give you a complete copy of the medical record and the biopsy report. The biopsy report will help an oncologist determine if additonal therapy is indicated.

    I can’t tell where you are currently, but Palladia is available in Europe. At AMC, we do not typically start any adjunctive therapy for mast cell tumors until the incision is healed and the biopsy results indicate treatment is appropriate.

    Dear Dr. Hohenhaus,

    My 11 year-old Schnauzer (m/n) has been diagnosed with MCT last week: one 1cm-diameter -tumor in his left hind leg and another minimal-size in his right shoulder. I’ve scheduled a surgery for him next week, and hope it will remove the tumors completely.

    Since we are now out of the States, I’d like to know how soon I can bring him back to the States.(It is a 14-hour-flight!) We were planning to return to the city at the end of November, but delayed it due to his surgery. Besides, I have no idea how to get the access to Palladia here, just in case he might need it. With the oncologist’s prescription, can I have it shipped to overseas? Or, should I have him get the surgery back to the States?

    Since I’m so devastated, any word from you will be really appreciated. I want to make sure I am doing the best for my dog.

    Thanks so much for your time,

    Warmest Regards,


  40. I do have experience with feline mast cell tumors, but cannot specifically comment of what should be done with your cat since he is not my patient. Like your cat seems to have experienced, these tumors do release histamine and other cellular products which cause inflammation and impede healing. The ear flap is a difficult area for surgery even without the problems a mast cell tumor causes. In the past, I have seen cats who we have needed a “van Gogh” procedure to eliminate a mast cell tumor from the ear flap. By removing the ear flap the surgery is far enough away from the tumor that cellular product release is less of an issue.

    I hope this information helps!

  41. Deb Fong says:

    Hi Dr. Hohenhaus,

    I believe you may focus more on mast cell tumors in dogs, however I am sure you also have extensive experience with MCTs in cats. My 9 year old grey tabby recently had a small MCT excised from the tip of his right ear. We are waiting results from XR and abdominal US to determine if there are any metastases. The pathology report is a bit unclear to me: “round cell neoplasm in dermis. Homogeneous sheet of cells characterized by round central nuclei, one small nucleolus, and moderate amphophilic finely granular cytoplasm. Lesion extends on each side of ear cartilage. MCT, tip of ear (microscopic finding). Lesion apparently excised, however it extends close (1-2 mm) to deep margins. Follow-up advised.”

    My main concern, pending scan results, is the reaction he experienced immediately after the excision. He had a fairly dramatic histaminic response, with significant swelling and redness. This remained local and did not appear to bother him. The vet administered diphenhydramine and corticosteroids, which appeared to help. I have been applying topical antibiotic/steroid cream for the last week. However, the vet is concerned about possible necrotic tissue. I am seeing still redness near the surgical site, with a small dark line also beginning to show. Swelling and redness overall are significantly improved. What should I do at this point? Vet is concerned about precipitating another mast cell degranulation if he attempts to laser off the questionable tissue. Thanks for any advice!

  43. Dear Jan,

    Management of canine mast cell tumors is complicated and I would recommend a consultation with a veterinary oncologist to help develop the optimal plan for you dog. The optimal plan may involve more surgery, radiation therapy or chemotherapy. Many drugs, including Palladia (click here to see our previous blog post) are useful in the management of canine mast cell tumors, but should be administered under oncologist supervision. To find an oncologist near you, go to http://www.acvim.org and “find a specialist.”

    Dr. Hobenhaus,
    My 8 year old f/s Basset Hound recently had surgery to remove a cyst on the top of her head, but when the vet went in he discovered it was a solid mass and removed it. Pathology showed it to be a MCT grade 2 and the margins had not been completely removed. She has her stitches out in a few days and I’m searching for what to do next. Oncologist and holistic vet is recommended by a few people I know and also a drug called PALLADIA which is supposed to be specifically for MCT’s. Question: Is Palladia being used now for MCT’s? What do you recommend?

  45. Mr. Blackwell,

    The causes of hair loss in cats are many. He might be itchy and licking himself is pulling out the hairs. Itchy skin in cats is caused by infections, ectoparasites and allergies. Cats with overactive thyroid glands may also groom excessively. When upset, cats will often lick excessively and make themselves bald. This time of year, houseguests, parties and the general hustle-bustle of the season may just be enough to make your cat feel anxious.

    I suggest a visit to the vet to determine if there is a medical condition causing the hair loss. If not, perhaps your cat needs some quiet time to cope with the season.

    My cat keeps licking all the fur off his belly? He is a Siamese marked and in good health. Would you know why he is doing this? All his fur is gone from the entire belly area.

  47. Yes, your best course of action is to speak to a veterinary oncologist. Additionally, for more information about Palladia, please refer to a recent blog post: https://amcny.wordpress.com/2009/07/21/big-news-in-cancer-treatment-for-dogs/.

  48. Carole Carrier says:

    Thank you for replying to my email..I lost my 13 yr old golden in July to “old age” and now to be facing cancer with my 12 yr old is really devastating…when I read about palladia I was hoping it was something I could try.

  49. I am so sorry you dog is sick. Palladia has activity in a wide variety of tumors, but I can’t tell from NYC if your dog would benefit from Palladia. I would suggest you find an veterinary cancer specialist (oncologist) near you to determine if Palladia is right for your dog.
    To find a veterinary oncologist near you go to http://www.acvim.org and click on “find a specialist.”

    Good luck.

  50. Carole Carrier says:

    My 12 yr old golden retriever was diagnosed with a tumor on his spleen yesterday…I understand these are 90% malignant..he also has arthritis in his hind legs…I have read about the drug palladia and was wondering if there was any available in Florida…my vet didn’t mention it …please advise

  51. All I can do is reiterate the results recently published, randomized, controlled clinical trial of Palladia, which was pivotal in winning FDA approval for the drug.

    In that study 60% of dogs with mast cell tumors experienced disappearance, shrinkage or no further growth of the tumor at the completion of the study. Dogs whose tumors responded to Palladia experienced an improved quality of live using a quality of life rating scale. This indicates the side effects of the drug were manageable.

    I hope this information is helpful.

  52. William Bodily says:

    The biopsy report did indicate Grade 3 and since it grew to be 4.5cm in size it was regarded as a Stage 3 tumor. I have instructed my vet to consult with the oncology departement at Cornell since I’m located in Syracuse.

    I was mainly interested to hear about any experience you may have had with Palladia. I know it’s new so you may not have even prescribed it for any of your patients, but I’m interested in that as a potential option. Thank you for your repsonse.


    William Bodily

  53. Mr. Bodily,

    Mast cell tumors are tricky. They come in 3 biopsy types, Grade 1, Grade 2 and Grade 3, but no two of the same grade are alike. Some are treated just with surgery, some with surgery and other treatments like radiation therapy, chemotherapy and now Palladia. Grade 3 are the most like to spread throughout the body and Grade 1 are readily cured with surgery. Grade 2 is somewhere in between.

    Stage is different than grade. Stage tells how large and how widespread a tumor is. Stage 3 indicates the tumor is large and it may also involve the lymph nodes.

    Kuruk likely needs additonal therapy beyond surgery to help control his mast cell tumor. I would suggest you and Kuruk see a veterinary cancer specialist (oncologist) in your area to help you determine what treatment is the best for your dog. Ask your regular veterinarian what veterinary oncologist they recommend. You can also find a veterinary cancer specialist at http://www.acvim.org. On the left side click on “find a specialist” and fill in the blanks to locate the one nearest you.

    Good luck to you and Kuruk.

    Dr. Hohenhaus,

    Last week my dog Kuruk, a 6 year old Alaskan Malamute, had a mass removed from his left flank. The mass turned out to be a Mast Cell tumor. The biopsy report suggests that a reoccurrence of the tumor is high as this was classified as a stage 3 grade 3 tumor. I saw your interview on FOXNews regarding the newly approved drug Palladia. I’m wondering if you have prescribed this drug yet and what kind of results you have seen. I’m also wondering about the cost for this type of treatment. Thank you for your time.

    Thanks, Dr. Hohenhaus!

    The information you provided was extremely helpful, and we look forward to working with you further.

    I just sent you an email follow-up.

    Thanks, again!


  56. Dear Ms. Ryan,
    I am sorry your dog is sick.

    Because extraskeletal osteosarcoma is so rare, we do not have good data on the optimal treatment for the disease. Those dogs with mammary gland or intraabdominal ESOSA seem to have the worst prognosis. In one study, the median survival for subcutaneous ESOSA was 240 days and skin was 486 days, although that was based on a small number of dogs. In a different and also small study, dogs receiving chemotherapy did survive a bit longer than dogs not receiving chemotherapy.

    It is good the tumor appears to be completely removed, although dogs with skin or subcutaneous ESOSA typically died from tumor recurrence at the surgical site. I would recommend you dog be evaluated for both radiation therapy and chemotherapy during your decision making process.

    I would be happy to see your dog. You may call AMC’s appointment desk 212 838 7053 to book an appointment with me. Thank you for reading the AMC blog.

    Dear Dr. Hohenhaus,

    Our 13 year old Springer Spaniel has been diagnosed with Extraskeletal Osteosarcoma. Two weeks ago, she had a very big tumor removed from her hind leg; we had been monitoring the tumor for about 12 months. (They got clear lateral and deep margins upon tumor resection). She’s such a champ — recovering so well from the surgery. :o)

    But today, when they were removing the stitches, our vet oncologist told us that it is a very bad prognosis, and recommended chemotherapy to prolong her life 8-12 months. We are not convinced if chemotherapy will even affect EsOSA. I saw that you wrote a paper on Canine Extraskeletal Osteosarcoma with the late Dr. Patnaik. Our vet says EsOSA is very very rare, and is saying it should be treated the same as regular OSA. I am researching this and finding conflicting and/or no information about EsOSA in relation to regular OSA.

    If we can make an appointment at the AMC, can you help us? We are very sad and afraid.

    Thank you in advance for your time.


    P.S. Thanks for your blog.

  58. Hi, Eddie!

    Nitrosylcobalamin is a drug undergoing clinical investigation in both human and veterinary oncology. It has recently received widespread attention in the press because some encouraging results were reported when the drug was used to treat dogs with anal gland adenocarcinoma. Research is still being performed to determine if this drug is safe and efficacious in people and animals. When that work is complete, we will know much more about the clinical utility of the drug.

    Thank you for reading the AMC blog!

Otherwise, if you’re planning on posting the information on your site in another way, we just ask that you credit The AMC and include a link to our website (www.amcny.org).

    Thanks for reading our blog!

    We like to keep our customers up to date on pet health issues on our website. I found the dental series very informative and was wondering if we may be able to use it on our site! Please feel free to visit our website!

  65. This would be a nice feature on our site, but it would be extremely difficult to set up something like this due to logistical issues within the hospital (not to mention very expensive). Additionally, we have so many clients that it would be nearly impossible for someone to log onto our website and see only their own pet.

    We do allow pet owners to come in and visit their pets if he/she is admitted for an extended period of time.

    Thanks for reading our blog!

    Hi Dr. Hohenhaus,

    Will it be helpful to show live views from AMC on AMC’s website? and for owners to be able to see their pets remotely?

    Please pm if you wish.
