Doggy Dash and Distemper

July 25, 2011

Dr. Nate Lam and his dog, Cali

On Sunday, August 7, The Animal Medical Center Doggy Dash will give man (or woman) and his or her best friend the chance to compete in tandem over a 5-mile run course in New York City’s Central Park.

The AMC’s Doggy Dash is part of the 11th Annual Nautica NYC Triathlon and one of The AMC’s own — Dr. Nate Lam — will be participating in the triathlon to raise money, in part, for The AMC’s Buddy Fund for Cancer Care.

Dogs in the Dash must be healthy and current on vaccinations. One Doggy Dash participant contacted The AMC asking what the “D” in DHPP vaccine was so he could find out if his dog had been properly vaccinated. This question gives me an opportunity to write about canine distemper – the “D” in DHPP.

Before the distemper vaccine was developed in the 1950s, canine distemper caused serious illness and could wipe out an entire neighborhood’s dog population. Today, distemper in dogs can easily be prevented, and vaccination against distemper is considered a “core” vaccination for dogs. Distemper vaccine is commonly administered in a combination vaccine often called DA2PP or DHPP for distemper, adenovirus 2 (also called canine infectious hepatitis), parainfluenza and parvovirus. Rabies vaccination is the other core canine vaccine. Non-core vaccines include bordetella (kennel cough), canine influenza, Lyme disease, leptospirosis and corona virus. Vaccination guidelines recommend non-core vaccines be administered only to dogs with risk factors for the disease.

The name canine distemper is a bit misleading. The disease does not cause an ill temperament in an infected dog. The word comes from a Middle English word meaning to upset the balance of the humors. Medieval theories of medicine proposed the body was composed of four substances called humors and when the humors were out of alignment, illness occurred. The distemper virus infects a wide variety of animals including the black-footed ferret, Tasmanian tiger, African wild dog and lions. Distemper virus cannot infect humans but genetically it is closely related to the measles virus.

Distemper has several clinical manifestations. The initial clinical signs are fever, vomiting and nasal or ocular discharge. These might go away without treatment, or could progress to systemic illness such as pneumonia. Neurological signs such as seizures may accompany the illness, or may occur months later. Dogs may also develop thickened footpads or nasal planum (the hairless part of their nose) giving the disease its colloquial name, hardpad disease. Years after their initial infection, old dogs may develop “old dog encephalitis” in which the brain becomes inflamed from chronic distemper virus infection. Canine distemper virus can even affect the teeth. Puppies infected before their permanent teeth develop have a decreased amount of enamel covering their teeth.

Distemper virus infection is easily prevented by vaccination. Following a puppy series of shots, your veterinarian will discuss the frequency of distemper vaccination that is appropriate for your dog during its annual physical examination.

National Pet Fire Safety Day

July 18, 2011

Last Friday, July 15, 2011, was National Pet Fire Safety Day. When we hear about pets and fires in the home, we often think of the dog who awakens his owner, saving lives with a warning bark about a fire in the house.

But pets are also the victims of fire. According to Pet Safety Alert, 40,000 pets are killed in fires annually, most of them in residential fires.

Every year, The Animal Medical Center provides care to pets who have been trapped in burning buildings and rescued by New York’s bravest, our friends at the NYC Fire Department.

As a pet lover, you can take action to prevent pet-related fires and to protect your pet if there is a fire.

To help firefighters find all of your pets, the folks at ADT Home Security Systems offer a free window cling to alert firefighters to the presence of pets in the home. You can request one through their website.

Firefighters want to help pets suffering from smoke inhalation, but the oxygen masks designed for humans are not shaped to fit a pet’s nose. If you are feeling philanthropic, donate a pet oxygen mask to your local firefighting team.

Pet proofing your home can help to prevent a catastrophic fire. Candles are a huge danger for pets. A wagging tail can knock a candle off the coffee table and into a pile of flammable papers. My own cat, who had a big puffy tail, swished it over a lit candle and nearly went up in flames! Space heaters and backyard grills present a hazard, as they can easily be knocked over by a pet and start a fire.

To protect the entire family, make sure your smoke detectors and carbon monoxide detectors have their batteries changed twice a year. A good time to change the batteries is when you change the clocks for daylight savings time in the spring and fall.

Like people, pets can suffer from carbon monoxide poisoning. If everyone in the family is ill and your pet is exhibiting the following signs, see your veterinarian and mention you are concerned about carbon monoxide poisoning.

  • Nausea
  • Vomiting
  • Cough
  • Loss of exercise stamina
  • Disturbances in gait

The Pen Cap May Be Mightier than the Sword…

July 15, 2011

But it can’t beat a bronchoscope!

Barcley

One thing I love about pets is their unpredictability. You just can never guess what they will do next. Here’s the story of Barcley, the French bulldog and the nearly fatal pen cap.

The beginning seemed innocent enough: a dog playing with a bright blue highlighter pen. Suddenly, he couldn’t breathe and his owners rushed him to The Animal Medical Center. Quick administration of oxygen and a sedative by the ER staff seemed to alleviate the breathing problem enough to allow a chest x-ray to be taken.

No one would have predicted the x-ray would show Barcley’s windpipe contained what looked like the cap of the bright blue highlighter!

Barcley’s chest x-ray. Arrows point to outline of pen cap in his windpipe.

The ER staff had to think quickly and cleverly. Barcley needed anesthesia and a bronchoscope to remove the highlighter pen cap, but the standard anesthetic plan of placing a breathing tube into the windpipe was out of the question; it was already full of the highlighter cap. To further complicate matters, Barcley is a brachycephalic (short nosed) dog, a type of dog known to have a greater risk of anesthetic complications.

Dr. Stacy Burdick of The AMC’s Internal Medicine Service was called in at 1:30 am to perform the procedure which took 20 minutes, but seemed like a lifetime. She placed a small rubber tube in the windpipe to deliver oxygen and administered an injectable anesthetic agent into Barcley’s vein. Dr. Burdick cautiously advanced the bronchoscope down Barcley’s windpipe. She was worried the windpipe could have been damaged as the cap went down, or worse, the windpipe could tear when she pulled it back up.

On the right, you can see what Dr. Burdick saw when the cap came into view. The cap blocked the entire lumen of the windpipe. Knowing she had to work quickly to restore the delivery of oxygen to the lungs, she passed a special grabber device through the bronchoscope, grabbed the cap and gently pulled it gently out through the mouth as she pulled out the bronchoscope.

Barcley’s life was saved from the pen cap by the mighty bronchoscope and the skilled Dr. Burdick.

Dogs and Cats as Diana and Orion, the Hunters

July 13, 2011

Pet owners believe their well-fed, or more likely overfed, dog or cat should have no reason to hunt, but lately it seems my patients are on a hunting spree.

Most cat owners who allow their cats outside, become accustomed to freshly killed gifts of mice and other small rodents carefully placed as an offering on the back stoop. But this week the take has been much more substantial.

Take Francie, for example, a special needs Cavalier King Charles Spaniel on anti-seizure medication. Twice last week she captured an unidentifiable furry creature and dragged it in through the doggie door. One unfortunate victim was hauled into Francie’s crate and the other left with pride in the middle of the kitchen floor. Franice’s family was outwardly distressed over her behavior, but the diminutive “Diana” seemed pleased with her hunting success.

Dixie and Mabel, a pair of Labradors, have not been hunting because they are, of course retrievers! To their owners’ initial horror, they were about to retrieve what appeared to be a dead possum, when the possum stopped “playing possum” and safely scampered back into the woods.

The Orion of the group is Willie, a handsome black Standard Poodle. He was out romping in his yard when a fawn strolled by. He tackled the fawn and was immediately tackled by his owners, who saved the fawn and had it safely transferred to the care of a wildlife rehabilitator.

I can share all these stories with you because the pet owners called me; not to brag, but out of concern for their pet’s health. Most were concerned about the potential for rabies transmission from wildlife. This is a real concern for pet owners and just one very good reason for having your pet vaccinated for rabies. Rabies vaccines are very effective and rabies is very uncommon in vaccinated dogs and cats.

Another concern is for parasite which can be carried by wildlife and transmitted to your dog or cat. The Dianas and Orions need annual fecal examinations and routine year round parasite prevention as recommended by the Companion Animal Parasite Council.

These pet owners also called wondering how to handle injured wildlife. First, you should not attempt to touch or move injured wildlife as you may be bitten. In New York State, the Department of Environmental Conservation licenses wildlife rehabilitators who can provide assistance and care for injured wildlife. There is also a FAQ page with great information about wildlife in your yard.

Everything Old is New Again: Plague and Leprosy

July 7, 2011

Nine banded armadillo, which can carry leprosy, seen in Brooklyn’s DUMBO neighborhood at modern:ANTHOLOGY.

Last week there were two very interesting stories in the news about the intersection between people and animals. Both reported on diseases we rarely hear about anymore: plague and leprosy.

Leprosy is the older disease and has been reported since Biblical times. The first reported epidemic of plague occurred somewhat later, in the 6th or 7th century. Bubonic plague, or the Black Death, was the scourge of the Middle Ages.

Plague is an infectious disease caused by the bacteria Yesinia pestis. The usual source of Y. pestis is the rat flea, but hunting pets can contract the plague from eating infected rodents or rabbits. Even though Y. pestis is predominantly found in California, Utah, New Mexico, Arizona and Nevada, cases can be seen throughout the country if a human or pet travels to one of these areas and contracts the disease before they return home. An infected pet can, in turn, infect humans. The possibility of plague transmission is one reason prairie dogs may not make the best pets.

The name bubonic comes from the word bubo, which is a fancy word for enlarged lymph node. Wikipedia shows an illumination from a medieval Bible of sinners afflicted with buboes.

Both humans and pets with bubonic plague have enlarged lymph nodes, which are painful. Fever, malaise and non–specific flu-like symptoms are typical for plague in both humans and pets. Although last week’s plague case occurred in a dog, in general, cats are more susceptible to plague than dogs.

Leprosy was in the news too; not because of a sick dog or cat, but because of armadillos. Those prehistoric-looking armored mammals carry the leprosy bacteria, Mycobacterium leprae. Most leprosy cases occur outside the United States, but cases occur in people who have not traveled outside the USA. This finding puzzled researchers until the DNA of the M. leprae was studied. Both armadillos and humans infected with M. leprae in the USA share the same unique strain of the bacteria. This bacterium is different from the strain of M. leprae found outside the USA. The New England Journal of Medicine article concluded humans can contract leprosy from infected armadillos.

To help protect yourself and your pet from contracting diseases of wildlife:

  • Keep your pet leashed or indoors to prevent contact with wild animals which can cause serious diseases.
  • Never approach, pet or handle wildlife even if they are acting friendly.
  • If your pet is sick, always tell your veterinarian where your pet has traveled and do the same when you visit your physician. It may be just the perfect clue to the diagnosis.

Summer Noise Phobias

July 5, 2011

Lovely weather, summer holidays and a relaxed atmosphere make summer everyone’s favorite season – everyone except for dogs with noise phobias. Fireworks and thunderstorms create unexpected loud noises, frightening to many dogs and cats as well. The veterinarians at The Animal Medical Center see dogs and cats injured and lost over the Fourth of July weekend as a result of their noise phobias.

Signs of noise phobia:

Destructive behavior

  • Scratching/digging at door or wall
  • Chewing
  • Loss of housebreaking

Anxious behavior

  • Clinging to owner
  • Drooling
  • Hiding, especially cats
  • Panting
  • Expressing anal glands
  • Dilated pupils

Abnormal behavior

  • Skipping meals
  • Jumping out of windows/running out of doors
  • Shaking
  • Loss of training, i.e., not responding to commands

Home Remedies
Consider trying home remedies for noise phobia. One of my patients with thunderstorm phobia calms down if her owner wipes her fur down with a dryer sheet. Dryer sheets may decrease the buildup of static electricity caused by the impending thunderstorm. I suggest the unscented ones, since dogs don’t like smelling like an ocean breeze. Anxious dogs may feel calmer during storms or fireworks if you apply a dab of lavender oil to their ear tips. The lavender oil fragrance has calming properties and is available at health food stores and on the internet.

Noise Phobia Products

  • Along the lines of the antistatic dryer sheet is the Storm Defender Cape which has a special lining to diffuse static electricity.
  • The Thundershirt is a snug fitting dog T-shirt which some of my dog owners have used for anxiety related to car rides, veterinarian visits, as well as thunderstorms.
  • An interesting product I found is dog ear muffs, but I don’t have personal experience with them.

For additional tips on managing fireworks phobia in dogs read a previous blog, “Fireworks and Your Dog.”

If you need professional help managing noise phobias in your pet, a behavioral consult with a Diplomate of the American College of Veterinary Behaviorists can help set your dog or cat on the road to recovery.

Cat Food Myths Debunked

June 30, 2011

A few months ago I wrote about cats and “cat salad.” Since we are at the end of Adopt–a-Cat month, I hope there are many new cat owner readers who will be interested in these food myths about cats. These myths have come from conversations with my cat-owning clients at The Animal Medical Center.

All cats like fish.
Partial myth. Cats’ food preferences are strongly influenced by those of their mother. If the mother liked and ate fish, the kittens are likely to crave fish as well. But the food preferences of the finicky feline are not so simply categorized. Despite the daredevil behaviors of young cats – flying from cabinet to refrigerator and scaling bookshelves with abandon – they are not so adventurous when it comes to food. Young cats fed the same diet consistently are often reluctant to eat a different diet if one is offered to them later in life. A cat food with a “good” smell is more likely to be chosen by a finicky feline, and if your cat doesn’t find any of the food attractive based on smell, it may taste several before choosing one. One fun fact about cats’ food preferences is cats probably don’t chose food based on salty or sweet flavors since their taste buds are insensitive to salts and sugars.

Cats should have milk to drink.
This is a companion partial myth to “cats like fish.” Some cats like milk, some don’t. Most cats lack the digestive enzyme, lactase, responsible for digestion of lactose, or milk sugar. A bowl of milk may lead to an upset stomach or diarrhea in cats. This situation can be avoided by treating your cat to a bowl of low fat lactose-free milk or one of the cat milk products available at the pet store. Since treats should comprise only 10% of the daily caloric requirement, keep the amount of milk to about 1/3 of a cup, or roughly 30 calories per day for the average 8 pound cat. Cat milk products have the added advantage of supplemental taurine, an essential amino acid for cats.

Cats can be vegetarians.
This is a myth, and a dangerous one. Nutritionally speaking, cats are obligate carnivores. Everything about their physical structure says “meat eater” from their sharp pointy fangs to their short digestive tract. Veterinarians will discourage owners from preparing vegetarian or vegan foods at home for their cats. Without the input of a specialized veterinary nutritionist, homemade vegetarian and vegan diets for cats are frequently deficient in taurine, arginine, tryptophan, lysine and vitamin A. Taurine deficiency leads to heart failure and a cat fed a diet without arginine may suffer death within hours. Both taurine and arginine are found in meat.
