Oh I'm sorry....was hoping to hear good news! My sister has had the same trouble with her Scotty and she has tried everything too...all different kinds of meds...different diets...numerous tests and vet visits...her poor dog is miserable a lot of the time
I think he is on a vegetarian dog food now along with some kind of medicine that is helping some though....I'll try to remember and ask her exactly what it is when I see her in the morning and let you know!
