Hi Sabrina-
Despite having normal hard stool, my bully mix will sometimes need to have his anal glands expressed. My boss/his vet explained to me that some dogs just do not have correct anatomy that allow them to express their anal glands on their own. You may simply need to learn how to do it at home, or bring him on occassion to the vet to have them do it. Sounds like you know what fiber % helps and what makes it worse, so find a food that has that fiber % and keep him on it.
Our dog also gets an annual ear infection in his left ear. We treat the symptoms and they go away. It happens at the start of summer time. I have ear meds on hand at all times.
As far as the dander goes, you didn’t mention how often you were bathing him and what you were bathing him with. Too frequent bathing can cause what you are seeing. Also how long did you use the fish oil supplements for and was the source of the fish wild caught? I did not notice a difference in my dog for a little over a month when I did fish oil supplements the first time. After about a month I started to see a difference.
Also it is ok to get a second opinion from another vet. I’ve done it even though I like the vet I see.
