I’m not in this to bash Blue Buffalo, but I have noticed a lot of people have dogs with digestion problems while on this particular brand. IIRC, they changed formulas not too recently so hopefully they will take complaints into consideration and make some more changes.
If you can get Fromm, or are willing to order, I’d go with Stacy’s recommendation. Another option would be a dehydrated food, some dogs don’t like it but others do and many seem to have less gastric complaints than they do on a diet of pure dry.
If the symptoms continue no matter what, a thyroid test might not be a bad idea. Low thyroid is surprisingly relatively common.
