My 11 month old chews, and scratches his body intensely. Mostly his legs and belly. He has lost his hair but has no sores or red spots

I would be concerned about fleas/mites and allergies. Typically I start treatment with flea prevention regardless if I see fleas or not. If there is hairloss I will also perform a skin scraping to rule out mites on the skin and if I suspect them I will start treatment. If there are no red spots or sores then it is less likely Bear has a skin infection. If either of those treatments don't work or it doesn't seem like he has either fleas or mites then I would start treatment for allergies. This can consist of daily medication (Apoquel) or monthly injections (Cytopoint). I hope Bear feels better soon and thank you for using Petco Pet Education Center, formerly Petcoach.
