Babesiosis in dogs is a parasite infection often transmitted by ticks. The condition is most commonly characterized by fever. Dogs’ normal body temperatures run a bit warmer than the typical human’s. Somewhere between 99 degrees F. and 103 degrees F. is normal for a dog. Other symptoms may include a loss of appetite; lethargy or an unsteady gait; or weight loss. Your pet may also exhibit a racing heartbeat, rapid breathing, and yellowish skin color or weight loss. You may also notice that your pet’s urine is brown. If you suspect your pet is suffering from babesiosis, your vet can help to determine a course of treatment. Babesiosis is worse for puppies; adult dogs might not need treatment.
