I have two Maltese. Wilbur is 7 and Missy is 11. Missy started to show signs of joint distress, slower to get out of bed and a little less agile. I knew glucosamine products were helpful but Missy is a very fussy eater and won't take pills so when I found this I thought I'd give it a try. It's got quality ingredients in the right quantity and it is 56% chicken AND it's made in the US. After a few weeks I can tell Missy feels better and I give it to Wilbur also since he LOVES it. It's his favorite "treat".
