I'm not sure it's helping. My oldest is 12 and he seems to have a little more energy. I do give him 2 scoops in the AM with his food. My other dog is about 8 pounds, and a year older than Lucky and gets 1 scoop in the AM with her food. Lucky is a min. pin mix and when I had him neutered he immediately got fat. Martini is a Chihuahua. She still chews on her feet, but I think that is her nervousness. I am on my second jar, but I am going to order more.
Bottom Line: Yes, I would recommend this to a friend
