You want at least 500 mgs.. After it doesnt work anymore, start glycoflex IMO as it has all 3 bone supplements.
I dont have a PetSmart here ... I wish we did . I'd spend a fortune there lol. Well okay maybe I'm glad we dont have one .
Thanks for the info it helped alot.. I will ask the vet about glycoflex..

I use Cosequin for Sleet. It costs a small fortune, but it works. It took about six weeks to see results.
How much is a small fortune? .
I will also ask the Vet about Cosequin.. Wow Sleet is 13!!! I didnt know that.
