This is my boy Khan, he's 11 this year and he was having trouble with is back legs after his runs but I put him on Doggy Daily Booster last year and no problems now. Just 2 teaspoons on a cup of kibble in the morning and cover with a little water so the kibble doesn't sit in his gut all day. Saved me $100 a month that the vet put him on which really upset him.
