I get Lady's Cosequin from Entirely Pets.
Cosequin Regular Strength (90 capsules)
I give her the full capsule every day. She has had terrible arthritis since she was seven. She was even on steriods for a few years until she developed Cushings from it. Cosequin has made a
huge difference for Lady, better than the steriods. I hope it gives your guy the same relief. What's his name?
