I've had dogs on amoxicillin, as well as using it myself. One time, Deb and I got bronchitis, and we were totally broke, so we couldn't go see a doc or get prescriptions. But we had dog amoxicillin in the cupboard, so we took that. It is the same thing in a different bottle. Deb and I asked our vet! It worked; we got over the bronchitis.
