How is your dog's digestion? How are his joints? It really is common that your dog is aging, like mine, and he is starting to get joint troubles, diarrhea, or constipation. This is typical as dogs age, but see the video I just discovered about a solution from this company:

My dog began getting digestive and joint troubles when she reached 8 years old. My vet advised that I find a probiotic and a joint supplement. I identified a lot of each, but this solution is the only one I've noticed that has them together in one chewable tablet.

Have you tried them? If so, I'd like to learn about your experience, so let me know!
