I'm 27 years old and I've had dogs in my house my entire life. My family had always used Purina One dog food. 4 years ago I bought my two lab puppies and we had started out feeding them Purina one as usual but when they were around a year old the vet told me that one of the dogs was overweight. They get a lot of time outside so I was pretty upset to hear that. When the vet and I were discussing the situation I found out that the food we had been feeding them has a lot of carbs and fillers and is not necessarily as good for dogs as my family had thought. He reviewed with me a bunch of other types and the IAMS weight control seemed like the best choice. It was healthy, available and not very overpriced. Since switching both of my dogs are at a normal weight and also seem much happier and healthier, they LOVE this food! I can get it at a grocery store, tractor supply or a pet supply store and its about the same cost as most brands of dog food. I am very glad I switched my dogs to this and so are they.
