Our male labrador has a raised bump that is smooth and hairless above his right little toe. It is the size of quarter and changes color. It is bright red and then pale pink. The bump is hard but seems to have liquid on the top and oozes a little pus. The bump has just developed this last week and it doesn't affect his walking.
This could be a cyst or a another type of mass. I recommend visit to the vet for a more accurate diagnosis. vetcare
