Pet's info: Dog | Labrador Retriever | Male | neutered | 2 years and 1 month old
Hi, my black Labrador (male, 2 yrs, neutered) has an open sore on the bottom of his paw surrounded by swelling. Onset seemed sudden to me; one day he started limping heavily, i noticed swelling, and a couple days later I noticed the sore. It seems painful.He has been on Cephalex for 2 weeks & the sore is getting larger in diameter and the swelling hasn't come down. We have been to the vet twice. hard yellow and black substances "growing" out of it in points/ peaks. Any ideas?
