Tried for over a week to get my 2 dogs to eat it. My 6 lbs., 13-year-old Chihuahua has a sensitive stomach and occasionally vomits. My 15 lbs. 3-year-old Shih Tzu will eat almost anything. I have been feeding Royal Canin or Science Diet for Digestive support kibble mixed with Pedigree canned. I added the Nutra Thrive at about 1/4 of your recommendation - basically sprinkled on. They both hate it. Sounded great if it would work as advertised, but can't work if the dogs refuse to eat it. Money back guarantee sounds like it is not worth the trouble. I will keep trying for a couple more weeks and if they still don't want to eat it, I will give it to my vet or a dog rescue and they can decide if it needs to be trashed.
Length of Use: Less than 3 months
Bottom Line: No, I would not recommend this to a friend
