When we adopted our aging golden, we never knew dogs could be so sensitive to chews and treats. Every time we gave him a chew, he would have instant diarrhea and a terrible stomachache. It was heartbreaking. We basically decided to just stop giving him anything because it wasn't fair to him. I was nervous to try Brü to be honest, and after giving him one, I watched him like a hawk for hours! I was shocked when he was totally fine! To see him be able to enjoy chews again is really awesome. I was so excited, I even told his vet!
