Does anyone feed a joint supplement as a preventative?
My mastiff is rising 4 years old, and I know she's a heavier breed of dog and would like to prolong the health of her joints.
What do you use?
I use MSM for my horses - can dogs have this? At what quantities? I know you can get glucosamine tablets for them (with contains both glucosamine and msm), and preferred brands?
Any natural alternatives?
