After waiting for three days for the vet approval at Petco, I was told that the product was out of stock. If that so, why do you still have the products on sale and telling me this after three days?

It really works! My 8 year old black lab was limping on her right rear leg from knee pain, my vet recommended 1/2 tablet twice daily. I begin with 1/2 tablet a day and after a few days the limp disappeared. That worked for 2 years, she recently began to limp again so I added the second daily dose and she is like a pup again.

This worked for Dog as he is having arthritis and it helped him a lot as he is still young as 2 years old. Petco delivered it fast and better price than his clinic

10/19 - it's been about a week with these meds.They look a bit larger than the ones my vet office provided but it's still small enough and seems to be working okay. My dog actually refused to walk home after making it down our usual path halfway. I'm unsure if it's the medication or environmental but it's rare for her not to make it home. So will be coming back and adjusting after a month.
