I have 5 dogs, 3 of which are seniors. I saw the film clip about your formula at the store and decided to give it a try. I only bought one bottle wondering how they would like pot roast flavor. They all loved the pot roast flavor and wait eagerly for their food. My Maltese is a very picky eater and she now eats her food every night. I have noticed my 3 year is not limping now and requires less pain medication. I like the ease of the product and they sure enjoy the pot roast flavor. I am giving them a supplement they like and it is easy for me – no pills to give.
