Since we’ve seen a lot of fleas in the vet hospital lately, might as well cover something about ticks too…

Anaplasmosis (Canine Granulocytic Anaplasmosis, etc.) is a disease transmitted by ticks. In dogs, it is caused by infection from Anaplasma phagocytophilum or Ehrlichia ewingii. The disease can appear in both dogs and cats mostly around age 6 to 8. Golden Retrievers and Labrador Retrievers make up a fair amount of the data but all breeds can be infected. Increased time outdoors in wooded areas coupled with poor tick control is a major risk factor for anaplasmosis. While humans can contract infection the previously mentioned bacteria, dogs are not a reservoir for human strains.

Symptoms are non-specific and include:

Dogs are treated with doxycycline or tetracycline with improvement seen mostly in 24-48 hours. Slow reaction to the drugs may suggest infection of another tick-borne organism in conjunction with anaplasmosis.
