My vet recommended Activex for my dog which is a horse joint supplement. She said to obviously feed a much lower dose. We did that for a while but Max being Max stopped eating it. She is finicky. I have recently found out, my vet personally takes Activex for herself too. I really liked the activex joint supplement but it is hard for me to find.

Since most of these companies provide horse and dog supplements, I bet if we really compared labels they wouldn't be too much different.
