Both my dogs get dry and meat like chicken, liver lamb or beef combo's daily. Once a week or so they also get the fat from the cow feet I use for my bone broth. I know this is the only new addition for the past 4 months or so, and the results are marvelous.
Lacey is a 15 yr. old Bichon Frise that has never been to the vet except for shots. She was slowing down or so it appeared, until the entrance of L'Ouija, a Maltese from a probable puppy mill. That's another story, however, she got a big dose of new life from this new arrival, but the biggest change in both that I see is the fat. She outrun L'Ouija in a soccar field the other day, and I couldn't believe my eyes. No one believes shes actually 15. They just had the fat the night before. It is cooked for more than 24 hrs, and served during the week in cut up squares. All I have to say is either "F-A-T", or "D-U-C-K", which is their favorites, they come running. Well at least Lacey does, since shes gotten deaf. That and the cataracts are next.
Also the food, which is a bit pricey, but 25% fat is a dry food called Annamaet. They also eat Orijens and the change really started when I switched to these dry, organic food with chelated minerals and high fat content. They also do not have many snacks, except for sweet potato and dried duck, as you know already. The skin on Lacey that had warts are gone. L'Ouija does gently nibble them away, but I've noticed the redness and irritation is gone. Bone broth itself they also get mixed in with the dry food. It is life-changing for all of us.
