Lyme Disease: A Pet Owner’s Guide
The bacterium that causes Lyme disease – a worm-like, spiral-shaped bacterium called Borrelia burgdorferi – is carried and transmitted primarily by the tiny black-legged tick known as the deer tick. Deer ticks are found in forests or grassy, wooded, marshy areas near rivers, lakes or oceans. People or animals may be bitten by deer ticks during outdoor activities such as hiking or camping, or even while spending time in their back yards.
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.
Lyme disease is a reportable disease – which means that health care providers and laboratories that diagnose cases of laboratory-confirmed Lyme disease are required to report those cases to their local or state health departments, which in turn report the cases to the CDC.
How to prevent Lyme disease
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.
As noted above, there are preventive Lyme disease vaccines available for dogs, but they aren’t necessarily recommended for every dog. Consult your veterinarian to see if the vaccination makes sense for your pets. If your veterinarian does recommend that your dog be vaccinated against Lyme disease, the typical protocol will involve an initial vaccination followed by a booster 2-4 weeks later and annual boosters after that.
Lyme disease in pets – symptoms and treatment
Pets infected with Lyme disease may not show any signs for 2-5 months. After that time, typical symptoms include:
- Loss of appetite
- Joint swelling
- Decreased activity
Recurrent lameness also is possible, and the involved extremity may be tender. Inflammation of the joint can last from days to weeks, and may migrate from one extremity to another.
Horses with Lyme disease can develop lameness, joint pain, neurologic disease, eye problems and dermatitis.
Symptomatically, Lyme disease can be difficult to distinguish from anaplasmosis because the signs of the diseases are very similar, and they occur in essentially the same areas of the country. 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.
It’s a “One Health” problem
Lyme disease in people
In humans, often the earliest indication of infection is a “bullseye” rash at the site of the tick bite – so named because it resembles a target. As the infection develops, symptoms include fever, headache, fatigue, and muscle and joint pain. The disease can progress to cause chronic joint problems as well as heart and neurological problems. As with pets, Lyme disease is not contagious from one person to another.
- Avoid areas where ticks are found
- Cover arms, legs, head and feet when outdoors
- Wearilight-colored clothing
- Use insecticides
- Checking for ticks once indoors.

- Our dog’s case of Lyme disease was picked up on a yearly routine test. He was fine and didn’t show any signs of infection. Our vet insisted that he be treated with over a month’s worth of antibiotics. Meanwhile, my husband spiraled down the vortex of doom for years. No blood test would pick it up. He tested negative on the two-tiered CDC testing. Thankfully, a wise “out of the box” doctor tested him for inflammation which was off the charts high. She said, “The CDC says you don’t have Lyme, I say you do,” and she treated him with two antibiotics – of which he improved immediately. Shortly after, I developed symptoms but also tested negative with CDC testing. By this time, I contacted a Lyme support group and became educated on the polarization within the medical community and had the list of WI LLMD’s in hand. We’ve been in and out of treatment ever since, having spent over $150K out of pocket, but have our lives back.
