Lyme disease in more detail

How is Lyme disease transmitted to dogs?

A tiny bacterium called Borrelia burgdorferi causes Lyme disease. These ticks usually hide in shady and moist environments and live in the leaf litter. Ticks climb on vegetation to wait for a host and climb on dogs when they move through grass, shrubs, or bushes.

What are the risks associated with Lyme disease?

Lyme disease is one of the most common tick-borne illnesses, and can affect dogs of all ages, sizes, and breeds. It is especially important. Ticks and tick bites are not simple to place on your dog. And signs of Lyme disease may be complicated to identify. To reduce tick bites and attachment, it is important that your dog receives regular and appropriate tick treatment.

What are the symptoms of Lyme disease in dogs?

Lyme disease can affect different body systems of the dog and the symptoms can vary. The most familiar symptoms in dogs are:

  • Reluctance to move
  • Fever
  • Leg or joint pain that often lasts for several days
  • Loss of appetite
  • Swollen lymph nodes
  • Fatigue

Can Lyme disease be transmitted from pets to humans?

While Lyme disease occurs occasionally in dogs, and much more frequently in humans, it is very rare for cats to contract it. Dogs cannot immediately communicate the disease to humans. However, the same infected ticks that carry the bacteria that causes Lyme disease in dogs can also attach and bite humans, which can lead to disease transmission. If you spend time outdoors with your dog, it’s a good idea to check yourself for ticks, wear protective clothing, and apply insect repellent.

How can I stop my dog ​​from catching Lyme disease or other tick-borne infections?

Be sure to talk to your veterinarian about the health risks posed by ticks in your area and ask for tick remover for cats to ensure your dog is protected against these nasty parasites.
