I have been using this brand of dog food for over 6 months now and the improvment of my dogs is overwelming to say the least. Weight is matained and skin and coats are in great condition. I have small dogs and they have seasonal allergies, since with this food, their allergies are less and they have better physical stimuli. Each one of my four dogs are over 12 years old, my dachshound is 19 years old and still runs and plays like a younger dog. My vet says she is as healthy inside and out as a 10 year old dog. Thanks to averoderm, she may be around a little bit longer. It is great.
