Rated 5 out of 5 by from Excellent food for our Great Dane puppy We got Cooper, our Great Dane puppy, at 1 1/2 months old. We started feeding him what the breeder was using. They are very nice people but not professional breeders. We slowly converted Cooper to a better brand of food . At 3 months our vet suggested we change to Science Diet Puppy Large Breed and are we ever happy She did. Cooper always took His time finishing the first 2 dog foods we were using and defecated a BUNCH. When we switched to Science Diet he finishes it quickly, completely and the defecation factor probably cut in half.....indicates to me that the S.D. food has a lot less filler in it. We are sticking with S.D. for the rest of Coop's life which will be a LONG time we pray.

Rated 5 out of 5 by from Our dog loves his food My puppy has been picky from the beginning, when our vet recommended your product we had to give it a try, as we had pretty much tried every other brand out there. Previously to trying your product, he would generally only eat about a 3rd of his food before walking away, from the very first day of trying your product our puppy loved it. He gave us what we call the "crazy tail" and ate every single bite, he licks the bowl and has yet to leave food behind. The food for puppy large breed has been a great for his coat, his teeth and his overall health! We have not switched our other dog and both cats to Science Diet and haven't looked back yet!

Rated 5 out of 5 by from Great Product/Great Customer Service During a recent grand re-opening of a Lawn, Garden and Pet Store, we conferred with a gentleman from Science Diet. He had explained that even though some pet foods may have a lot of vitamins and stuff in the food, this may not be good for all dogs. In our situation with our Mastiff mix, his bones are already growing very rapidly. if the food contained too much calcium, his bones would grow even faster and not give his body time to catch up. We had another mastiff mix that was having trouble as he indicated. Sadly, we had lost him last fall. He gave me a free 40lb bag of Large breed puppy food and a bag of treats. The puppy loves the treats. My daughter was working with him getting him to learn sit. He picked it up very quickly because he loves those treats. After eating the Science Diet food, we can see his coat is very thick and healthy looking. Very satisfied with the product and the representatives.

Rated 5 out of 5 by from Great for preventing long term problems in large breed dogs This is an excellent food for a large breed puppy and I always recommend it first to anyone who has one. The long term difference is amazing. I have a 5 1/2 year old great Dane who started on this food and then switched to large breed adult... My dog has never shown any signs of joint problems and still acts like a puppy.... Now I have a new great Dane puppy to add to my family... She's on large breed puppy food now and I would never consider changing to another food

Rated 5 out of 5 by from Awesome Stuff! Science Diet hands down is the best dog food made. Period. I've been using there food for all my dogs " Rottweilers" for over 20 years and this stuff works to perfection. They love the taste they put on the weight but not to fast they always have a beautiful healthy coat. This stuff is awesome. My recent new born Ray Ray was born on Dec 15th 2014 was of coarse winged off the breast and put on Science Diet Puppy Food for large breed around 6 weeks old and I took him for his check up today 06-05-2015 and he weighed in at 76lbs and is not even 6 months old yet. He is healthy and growing like a horse. My vet always says how well Science Diet works so don't waste your time on anything else. If you want the best for your fur babies then buy Science Diet.

Rated 5 out of 5 by from Woofs it down good We tried two other brands and now vet recommeded Science Diet Large Breed Puppy food. Our Rottweiler is 4 months old, loves the chow and growing like a weed on steroids. I can see the growth in him every single day. The vet was amazed with his shiny soft fur. Science Diet Large Breed Puppy chow gives the pup what it needs. If you want the food bowl to shine like his fur just mix a couple spoons of canned food in and he will lick it clean.
