Preventing Lyme Disease

If you live in the northern portion of the Mississippi River Valley or in the northeast as I do, June, July and August are peak months of incidence for Lyme disease in humans. These are the peak months for Lyme disease because the young Ixodes ticks (nymphs) carrying the Lyme disease organism (Borrelia burgdorferi) are most active in the late spring and summer.

Peak tick activity coincides with peak outdoor activity for both humans and pets, giving the young ticks an opportunity to attach and transmit the infection. In dogs, clinical signs of Lyme disease develop 2-5 months after a tick bite. Veterinarians can detect evidence of exposure to Lyme disease in the blood of cats, but cats seem to be more resistant to developing clinical signs of Lyme disease than are dogs.

Several different products are available to prevent tick infestation in dogs and cats. These days, the most common is a top spot solution applied between the shoulder blades of your dog or cat. Collars and sprays to prevent both ticks and fleas are also available. Ask your veterinarian which type of product will work best in your neighborhood and on your pet.

Annual vaccination is also an option for preventing Lyme disease in dogs. A vaccine is not available for preventing Lyme disease in cats. The Lyme vaccine is not considered a “core” vaccine and every dog does not require this vaccination. When you make your annual well dog visit to your veterinarian, put this vaccine on your list of topics to discuss.

Your backyard will be a source of ticks on your pet. Keep your dog and cat out of areas where the bushes and grass are not trimmed. Wooded areas should be off limits to dogs and cats in Lyme country. As pretty as deer are to watch in your backyard, they can serve as vehicles for tick transportation. Don’t attract deer by feeding them since they can bring ticks with them.

Should your dog or cat come home with a tick imbedded in its skin, removing the tick immediately will help stop transmission of the Lyme causing organism and only requires a tweezer. Grab the head of the tick as close to where it attaches to the skin and pull the entire head out of the skin. There is no need to use petroleum jelly, a match or a sharp object to remove a tick, and in fact these may cause more harm than good.

Preventing Lyme disease in your pet will have a positive impact on your health as well. Pets cannot give Lyme disease to their human or animal family members. They can, however, bring home ticks which can attach and transmit the Lyme disease-causing organism to your family or your other pets.

Not all ticks carry Lyme disease. If you want to identify the tick you just pulled from your cat or dog as one that carries Lyme disease or not, most state departments of health have a website for identification of the ticks commonly found in your state. I recommend this website to my New York pet owners:

Keep in mind a tick bite does not equal Lyme disease. Only a small percentage of tick bitten pets will develop clinical signs of Lyme disease. Lyme disease is not the only tick borne illness of dogs and cats, others include babesiosis, anaplasmosis and ehrlichiosis. If your pet is acting sick, see your veterinarian and don’t forget to tell her about the tick bite.
