I adopted Barney about 3 years ago. He is now 15. Having dogs my whole life, I always tried to match good healthy food with my dogs. Not all brands are for all dogs. I tried many different brands with Barney, without a lot of success. I would have to wake him up and bring him to his food bowl, to watch him walk away a few minutes later. About 4 months ago I switched to Fresh Pet Vital Grain Free, and see a ton of success. He now wakes up on his own and runs to the bowl, dances around while I fill up his bowl, chows it down with his last 5 teeth that he has left, and has a lot more energy through the night. He digests it well, and his stools are great. I now have one happy older dog. Thank you!
