This is good for one of my Labradors but not the only, only because the other will not eat his food when this is mixed in. I use 2 scoop per day, scoop provided in package and it keeps my dogs from going lame. They run and play hard. I walk them between 70 and 80 miles per week, plus they swim 3-5 times a week. My dogs are 8 and 9, and using this keeps at least the one running strong.
