Lyme disease in dogs, also known as Lyme borreliosis, is a tick-borne bacterial infection caused by the bacterium Borrelia burgdorferi. It’s transmitted to dogs through the bite of infected black-legged ticks that are carrying the diseased bacteria. Lyme disease can affect dogs of all ages and breeds, and it is more commonly seen in areas where ticks are prevalent, including wooded and grassy regions.
How Do Dogs Get Lyme Disease?
A spiral-shaped bacterium called Borrelia burgdorferi causes Lyme disease. It’s transmitted to your dog when an infected tick bites him.
Signs of Lyme Disease
Signs and symptoms of Lyme disease in dogs can vary, and some infected dogs may not show any symptoms at all. Common signs of Lyme disease in dogs may include:
- Lameness: One of the hallmark signs of Lyme disease in dogs is recurrent lameness that may shift from one leg to another. This can be due to joint inflammation caused by the bacterial infection.
- Fever: Infected dogs may develop a fever, which is usually low-grade but can occasionally be high.
- Lethargy and decreased appetite: Lyme disease can cause dogs to feel lethargic and have a decreased appetite. They may appear less interested in their usual activities and food.
- Joint pain and swelling: Lyme disease can cause inflammation in the joints, leading to pain, swelling, and discomfort. Affected dogs may show signs of joint pain, such as limping or stiffness.
- Enlarged lymph nodes: Dogs with Lyme disease may have swollen lymph nodes, which may be palpable as lumps under the skin.
- Other general signs: Dogs with Lyme disease may also exhibit other general signs of illness, such as vomiting, diarrhea, and changes in urinary habits.
It’s important to note that not all dogs with Lyme disease will show clinical signs, and some dogs may carry the bacterium without showing any symptoms. However, untreated Lyme disease can lead to more severe complications, such as kidney damage, heart problems, and neurological issues.
Lyme Disease From Tick Larvae
Lyme disease in dogs is primarily transmitted through the bite of infected black-legged ticks (also known as deer ticks) that are in the nymph or adult stage of their life cycle. Tick larvae, which are the smallest and youngest stage of ticks, are not known to transmit Lyme disease to dogs or humans.
The life cycle of the black-legged tick includes four stages: egg, larva, nymph, and adult. The tick larvae hatch from eggs and typically feed on small mammals, such as rodents, during their first blood meal to obtain the nutrients needed for growth and development.
If the tick larvae acquire the bacterium Borrelia burgdorferi, which causes Lyme disease, during their blood meal from an infected host, they can carry the bacterium in their body. However, these infected tick larvae are not considered capable of transmitting Lyme disease to dogs or humans during their first blood meal.
After the tick larvae feed and molt, they develop into nymphs, which are larger and more capable of transmitting Lyme disease. Nymphs can bite and transmit the bacterium to dogs or humans during their second blood meal.
If the nymphs acquire the bacterium during their first blood meal as larvae, they can transmit it during their second blood meal as nymphs. Nymphs are responsible for the majority of Lyme disease transmission to both dogs and humans.
It’s important to note that tick larvae are extremely small and difficult to detect, as they are typically the size of a pinhead. Therefore, it’s crucial to use proper tick prevention measures, such as regular tick checks, tick repellents, and avoiding tick-infested areas, to protect both dogs and humans from Lyme disease and other tick-borne infections.
Natural Ways to Prevent Lyme Disease in Dogs
There are several natural ways to help prevent Lyme disease in dogs, which involve reducing their exposure to ticks, the primary vectors of the disease. Here are some natural methods that can be used in combination to help protect your dog from Lyme disease:
- Keep your dog’s environment tick-free: Ticks thrive in wooded areas, tall grasses, and leaf litter. Keep your dog’s environment well-maintained by regularly mowing your lawn, clearing away leaf debris, and keeping your dog on well-groomed trails or paths when going for walks or hikes. Avoid letting your dog wander into tick-infested areas.
- Use natural tick repellents: There are several natural tick repellents that can help deter ticks from latching onto your dog. These may include essential oils such as eucalyptus, lemon, lavender, and cedarwood. You can create a homemade tick spray by diluting a few drops of these essential oils in water and spraying it on your dog’s fur, avoiding their face and eyes. Always consult with your veterinarian before using any essential oils or natural products on your dog to ensure safety and effectiveness.
- Check for ticks regularly: After spending time outdoors, thoroughly check your dog for ticks. Pay close attention to areas such as the head, neck, ears, and underbelly where ticks tend to hide. If you find any ticks, remove them promptly and properly using tick removal tools or tweezers, grasping the tick as close to the skin as possible and gently pulling it straight out without twisting or crushing it.
- Consider tick-repellent collars: There are natural tick-repellent collars available that use essential oils or other natural ingredients to repel ticks. These collars are worn around your dog’s neck and can provide additional protection against ticks.
- Feed your dog a healthy diet: A strong immune system can help your dog fight off infections, including Lyme disease. Providing your dog with a balanced and nutritious diet can help boost their immune system and overall health.
- Consider natural tick-preventive supplements: There are some natural supplements available, such as garlic or neem, which are believed to have tick-repelling properties. However, it’s important to consult with your veterinarian before giving any supplements to your dog to ensure safety and effectiveness.
- Vaccination: Talk to your veterinarian about the availability of Lyme disease vaccines for dogs in your area. Vaccination can help protect your dog against Lyme disease, but it’s important to note that no vaccine provides 100% protection, and it should be used in combination with other preventive measures.

Natural Products Can Help But Nothing is 100%
Remember, while these natural methods can help reduce the risk of your dog contracting Lyme disease, no method is foolproof. Regular tick checks, prompt tick removal, and consulting with your veterinarian for appropriate preventive measures are essential to protect your dog from Lyme disease and other tick-borne infections.
