I am wanting some advice re: dog foods. I have a 12 year old whippet, 1 year old cocker spaniel and 4 year old saluki greyhound. I have tried numerous foods and not had any luck. I have tried raw, currently on eden however my dogs have lost weight and don't look as healthy as I would have imagined on such an expensive and good quality food. I am really struggling looking for another food. Anybody share any help/advice/ good quality foods for a reasonable price given I have 3 dogs to feed!!!
