Why is my puppy licking and biting his fur off? Dry skin or allergies?

Pet's info: Dog | Labrador Retriever | Male | unneutered | 4 months and 26 days old | 40 lbs

I feed my dog Nutrience Sub Zero Puppy food, he is 5 months old and the last month he has started licking and biting his fur off at the legs and sides. He has flea medication in a pill form. I cannot see any bites or red spots. His skin is "dry" when I scratch him. Would it be environmental? I have bathed him twice since getting him at 8 weeks. Should I try a bath with an oatmeal type or just see when the grass goes this winter? I just started giving him wild Alaskan salmom oil yesterday to see

Poor Beaumont sounds very itchy!! I would recommend having him checked over by your regular veterinarian. In a young dog like this I would be concerned about a flea allergy (he may need to be started on a topical flea treatment rather than the oral pill), Demodex mites, or an environmental allergy. Salmon oil can be very beneficial for skin health, but it will likely be a few weeks before you see results-take care not to use too much at first as it can cause tummy upsets initially. Your vet may recommend some skin diagnostics such as a skin scrape or cytology to help determine the nature of the problem for Beaumont. Depending on their findings they will then help you to form a treatment plan to get Beaumont feeling and looking better.
