I have worked in various veterinary hospitals over the years, and am currently attending a veterinary school, and have never had any complaints about this product. There are many great pet foods out there, and different ones may be the best for different pets. Hill's Science Diet most definitely deserves consideration though. Their products have been well researched, and you can often find very specific diets for your individual pet. I have been feeding my 4 month old Boxer the Large Breed Puppy food, and he absolutely loves it. There hasn't been a morning or night when there has been any leftover food in his bowl. I like this food because it's nutrition is matched to the growing needs or larger breeds, so that growth is not too slow or fast. I recommend anyone do lots of research when choosing a pet food, and most certainly include Hill's in that search.
