Where are you located? Was Buddy exposed to ticks any time in the past few months? High WBC and low platelets with lameness often indicates tick-borne disease. We see that a lot with anaplasmosis. Test results can be misleading, so we usually treat with doxycycline or amoxicilin even if the snap test is negative and see if there is improvement. If there is, we keep them on antibiotics for at least 4 weeks.
