My puppy keeps biting his leg and has hair loss where he is biting. Also has hair loss around his left eye and nose. What could be wrong? It does look infected where he keeps biting. He is only 5 months old.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is likely either due to mites or allergies. I highly recommend that you have him evaluated by a veterinarian for further assessment and treatment. They would be able to diagnose this so that therapy can be started. Best of luck!
