Allergies & Leg infection?!?!

Here are some pictures of Coby's latest "problem" that we believe is allergy related. His leg had been getting progressively worse over the past week or so - going from a dry slightly red skin to a bright red color and moist skin. He is now on a daily antibiotic (clavamox) which was started Wednesday night. Hopefully this will be the answer we need, besides just wearing the e-collar. We have a follow up appointment with the dermatologist Tuesday morning.
