I need some advice.....I was wondering if anyone has heard of Natural Ultramix Adult Dog food and if you could offer any advice on it? It doesn't have any corn or wheat in it & the first 3 ingredients are meat. I am trying to find a good dog food for my 8 year old 40lb husky dog, any suggestions? It seems like she does fine with any new food for a while then doesn't want to eat anything causing her to get really lethargic and low energy. If i can get her out of the house she is excited to go on walks but it is hard to motivate her to do much of anything. I don't know whether it is her food that is causing this or something else. Any words of wisdom or ideas?
