So I have 2 doodles, a 1.5 year old goldendoodle and a 5 month old mini Bernedoodle, and they seem to have diarrhea at least once a week. We've taken them to the vet many times and they can't find anything wrong to be causing it. We don't allow them to have people food or treats and they are both currently on blue buffalo chicken and rice recipes. Anybody else experience this? Any food suggestions that may be better for them?
