What Are the First Signs of Lyme Disease in Dogs? The first signs of Lyme disease in dogs often include lameness, fever, and lethargy, which typically appear 2-5 months after a tick bite.
These early symptoms are key indicators that your dog may have been infected with the bacteria that cause Lyme disease, Borrelia burgdorferi.
Early Symptoms of Lyme Disease in Dogs
Lyme disease, a tick-borne illness, can be tricky to detect in its early stages. Dogs may not show immediate signs after being bitten by an infected tick, so recognizing the early symptoms of this disease is crucial.
- Lameness and Joint Pain: One of the most telling signs of Lyme disease in dogs is lameness, particularly shifting-leg lameness, where the dog appears to limp on one leg and later on another. This is due to joint inflammation, which can cause stiffness and pain. This lameness may come and go, leaving many pet owners unsure if it’s a serious problem or just a minor strain.
- Fever: A fever is another common early sign of Lyme disease, often exceeding 103°F. If your dog seems warm to the touch or shows other signs like lethargy or poor appetite, it’s essential to monitor their temperature.
- Lethargy and Fatigue: Dogs with Lyme disease may become more tired and less playful than usual. Lethargy and a lack of interest in activities like walking or playing are common in the early stages.
- Loss of Appetite: A sudden loss of appetite can be another early warning sign of Lyme disease. The discomfort from fever and joint pain may cause your dog to eat less or stop eating altogether.
- Swollen Lymph Nodes: In some cases, dogs may develop swollen lymph nodes as their immune system responds to the infection. These are often located near the neck, shoulders, or hind legs.
According to Dr. Mary Labato, a veterinarian at Tufts University’s Cummings School of Veterinary Medicine, “Lyme disease often goes undiagnosed because its symptoms can mimic other common conditions like arthritis or general fatigue. A fluctuating limp in your dog is one of the most prominent signs of infection.”
How Lyme Disease is Transmitted
Lyme disease is caused by the bacterium Borrelia burgdorferi, transmitted to dogs through the bite of infected black-legged ticks, also known as deer ticks.
These ticks are commonly found in wooded or grassy areas and need to be attached to the dog for around 24-48 hours to transmit the bacteria.
