I have a 4 month old bleu weimeraner. She’s had diarrhea for 3 weeks now. We’ve tried changing her food. Cutting out treats.. so many things but nothing is helping.

Since she has had diarrhea for 3 weeks, she should be examined by a vet to determine the cause. She could have an intestinal parasite and your vet can run a fecal test to see if she has one. Your vet can also prescribe medications to help treat the diarrhea. You could also try a bland GI diet and add a probiotic (Fortiflora, Proviable, etc.) and see if that helps, too.
