April is Prevention of Lyme Disease in Dogs Month and it's the perfect time to talk about this illness that affects both animals and humans. By knowing about Lyme disease and how to prevent it, you can help keep all members of your family — human and animal — safe.
It's known as a zoonotic disease – and is the most commonly reported vector-borne illness in the United States, according to the U.S. Centers for Disease Control and Prevention (CDC). Transmitted through tick bites, the disease can be difficult to detect and can cause serious and recurring health problems. Therefore, it is best to prevent infection by taking appropriate measures to prevent tick bites and, for dogs, possibly vaccinating against the disease.
Named after numerous cases were identified in Lyme, Conn., in 1975, the disease has since been reported in humans and animals across the United States and around the world. Within the U.S., it appears primarily in specific areas including the southern New England states; eastern Mid-Atlantic states; the upper Midwest, particularly Wisconsin and Minnesota; and on the West Coast, particularly northern California. The CDC maintains a map detailing confirmed cases of Lyme disease throughout the years.
The best way to protect pets from Lyme disease is to take preventive measures to reduce the chance of contracting the disease. Even during the last weeks of summer, it's important to remember that pets and people are at greater risk of being infected with Lyme disease and other tick-borne diseases such as anaplasmosis, ehrlichiosis, or Rocky Mountain Spotted Fever.
People with pets should:
- Use reliable tick-preventive products. Speak with your veterinarian about what tick preventive product is right for your pet.
- Work with your veterinarian to decide whether to vaccinate your dog against Lyme disease. Your veterinarian’s advice may depend on where you live, your pet's lifestyle and overall health, and other factors.
- When possible, avoid areas where ticks might be found. These include tall grasses, marshes and wooded areas.
- Check for ticks on both yourself and your animals once indoors.
- Clear shrubbery next to homes.
- Keep lawns well maintained.
Pets infected with Lyme disease may not show any signs for 2-5 months. After that time, typical symptoms include:
- Fever
- Loss of appetite
- Lameness
- Joint swelling
- Decreased activity
Lyme disease is diagnosed through a blood test that shows whether an animal has been exposed to the bacterium.
Antibiotics usually provide effective treatment for Lyme disease. However, it’s important to follow your veterinarian’s advice regarding follow-up care after your pet has been diagnosed with and treated for the disease.
Lyme disease is not communicable from one animal to another, except through tick bites. However, if you have more than one pet and one is diagnosed with Lyme disease, your veterinarian might recommend testing for any other pets who may have been exposed to ticks at the same time.
