I love the dog food they carry; here is some research that I found:
Pound for pound, the well-known brands sold in supermarkets and major pet food chains are obviously a lot cheaper. However, many pet-nutrition experts say that the initial cost difference doesn't tell the whole story. According to veterinarians at ThePetCenter, the higher-quality ingredients in premium food mean your dog will actually eat less compared to inexpensive dog food: ""Immediately you will notice that when feeding a high-quality, meat-based food, the dog will need to consume fewer cups of it per day than a cheap diet."" An added benefit is that because more of the food is absorbed as nutrients, your dog will pass less solid waste.
Experts also point out that suggested serving sizes are just that -- suggestions. Feeding needs vary greatly depending on your dog's breed and activity level, and serving guidelines are merely a good jumping off point. A dog that spends all day running around in the yard will obviously need more food than a sedentary dog. Observation will tell you if your dog needs more or less food.
