My golden retriever is constantly biting and scratching. I assumed he has fleas and have treated him with flea drops and collar. However, I have inspected his fur and cannot find any fleas. He has begun to bite and irritate his skin. I called our vet, but am unable to get an appointment for quite a while. May there be another common cause for this?
Allergies, mange, skin infections, fungal infection are just a few other causes for itchy skin. Vetcare
