Canine Babesiosis

Canine babesiosis is caused by an infection with the organism Babesia, which is frequently transmitted by ticks. It is a blood parasite that infects your dog’s red blood cells. It usually takes approximately 24–48 hours after attachment of the tick on your dog for the infection to be transmitted.

Clinical Signs
It will depend on the species of Babesia and the individual dog on how they will react when infected with babesiosis. The disease can be mild or severe, and your best friend may show obvious signs of being sick, or no signs at all.

If you suspect he isn’t feeling well, you should contact your veterinarian immediately. To learn more, watch this video on protecting your dog from ticks.

If your veterinarian suspects your dog may have a tick-borne disease such as babesiosis, she will most likely recommend some blood tests. These may include:

  • A complete blood count to see if your dog is anemic
  • A blood film to look for the microscopic organisms in your pet’s red blood cells
  • Other tests, such as PCR testing

If it is determined that your dog has babesiosis, your veterinarian will discuss which medications are right for them. These may include a drug called imidocarb dipropionate, which is known to be effective against Babesia  Other medications may be used as well, and your veterinarian may suggest supportive care until your dog’s clinical signs improve. Ensuring that you give your pet all of their medication is paramount to their recovery.

The key to preventing any tick-borne disease is tick prevention. Check your dog daily for ticks, and talk with your veterinarian about the right tick prevention medication for your best friend. Annual testing is also important to protect your dog from ticks. Learn more here.
