Was pups first type if hard/crunchy food. My pup loved it but we noticed he didn't get all the nutrition he needed. Wr bought powder to get him where he neededbto be. He grew out of the puppy food and has now changed to something else's. This was his only food he ate for the first year of his life as he didnt like any other brand we bought. He's a chocolate Labrador. This product may and my not be best. Some dogs don't get enough nutrition from this product if you notice this happening then please feed your dog something different.

For almost 18 years, we have had so many furbabies, all Science Diet babies! I strayed once, fell for the allergy hype and all 3 black labs gained 20 pounds by their next wellness visit. Back to SD LIGHT (and nothing else foodwise changed) and they were back to their good weight. So many healthy babies in this family, all SD babies! I love the large breed light for the weight control and the joint health. We have also used the puppy large breed and the Perfect Weight (a little harder to find in Western CO) as they become more couch spuds and less bird dogs!

Bigger bag and dogs like the food.

I have a Beagle who cannot have dental cleanings by the vet anymore due to her heart condition. I asked my Vet for a prescription plan dog food but found the other two companies make smaller bags that I would have to order two or three bags at the most to last a while. I decided to go with this instead. They are a lot bigger than the usual food she ate but so far she has been able to eat them. I do wish they were a little smaller but I guess the size is what helps with the oral care. My smaller terrier also likes it as well and I like the bag size.

Does what it says! We love Hills!
11 December 2022

One of our dogs had been on her other food for awhile but was gaining weight. It was a nicer brand so was surprised. Our vet recommended finding a food that notes weight management or healthy weight. There was a version with the food she was on so we switched to that and it seemed to leave her really hungry and was getting sick which was very odd for her. We quickly switched to this Hills option because our other dog uses Hills prescription food and that has been life saving so knew we could trust the food to perform. She’s been on this food for several months now with no issues, lost her excess weight, and has maintained. She’s happy so we’re happy!

I have two Labrador Retrievers and both were always said to be big boys when they got older. Well they were wide and big! One weighed 95lbs and the other weighed 103lbs and we’re not even a year old. We tried different brands and found that not only did this help with their patchy, yes patchy fur, it also helped with weight and they love it. They are both now 89lbs and the other is 99lbs and we have been on it for 2months now. Now the weight clearly didn’t come off quick but it is coming off and the vet is happy with the progress. Also might I add, they do stool a lot more but they do not seem hungry or searching for food! We only feed them 3-4cups a day and the vet recommended 2cups, but that won’t happen at all, sorry vet!!

Overall we are so impressed and are so happy we switched. Our dogs are sensitive dogs and coming to Hills has been by far the best. Work some overtime if cost is a complaint. We can get 3-4weeks with two dogs on one 30lb bag. Mind you they do not eat the 4cups every day per dog! If you eat good, your dog should as well!

Hills Science is the best....
20 February 2022

My puppy is a large breed and eats at least 2-21/2 of this every month. she does not like to eat pure dry food so i always have to mix it (4 cups dry food and 1 can wet food). I started feeding her Hills Science when she was 2 months old and i had just gotten her from a breeder. She had come with a bad case of worms/diarrhea and would not eat anything but water and bland bread or rice, i tried various foods but she wouldn't even touch them. My vet introduced us to the Digestive Care ID Diet both wet and dry and she ate date to my surprise so when she got better, i transitioned her to Large Breed Puppy Diet above and never went back to any other food. Thanks Hills Science for providing such wide varieties of top quality products for a variety of circumstances and ... MoreMy puppy is a large breed and eats at least 2-21/2 of this every month. she does not like to eat pure dry food so i always have to mix it (4 cups dry food and 1 can wet food).

Perfect food for our dogs!

We have an 8-year-old black lab and when his 13-year-old companion died last fall, he was devastated. We got him a new buddy in the form of a little black lab girl and they quickly became best friends. Cooper and Cadie are the 5th and 6th black labs we've had over the past 25 years.Our dogs have always eaten their Hills Science Diet from the same bowel and we keep the bowl full so they can self-feed. We are very lucky that none of them have been particularly food focused and they have never been over weight. Since the puppy requires puppy food (she's 9 months now), we have been feeding both dogs the same Hills Science Diet Large Breed Puppy food. We were a little concerned that our older dog might gain weight eating puppy food but that hasn't happened, so we are ... MoreWe have an 8-year-old black lab and when his 13-year-old companion died last fall, he was devastated.

Purchase directly from Hills, SIGNIFICANTLY less $
18 November 2022

This is a great product for large breeds. I highly recommend purchasing directly from Hills, however. Their list price is $62.70. No reason to pay an additional $15 to Petco. Additionally, if your vet participates in Hills VIP market, the cost is $47.03 and is shipped for free to your vet's office. If your vet doesn't participate, ask them to consider it. The savings is fantastic.

When I took my now 5 month old Goldendoodle to her initial puppy checkup part of the package included a small bag of Hill’s Science Diet Large Breed Puppy food. I had previously done research on puppy food and decided to go with another brand. My Vet recommended I use the Hill’s Science Diet as training treats. I did. My puppy loved the Hill’s Science Diet so much I made the switch and now feed it to her daily. Except for the short period when she was going through loosing her puppy teeth and it her for her to chew crunchy food, she gobbles down each meal. Tractor Supply has the best price for Hill’s Science Diet, beating all the big box stores and online stores. On top of that they frequently run specials which saves me even more. I highly recommend Hill’s Science ... MoreWhen I took my now 5 month old Goldendoodle to her initial puppy checkup part of the package included a small bag of Hill’s Science Diet Large Breed Puppy food.

Worth every penny
12 October 2022

My pitbull mix is getting up there in years, so I've been blaming her low energy on that for a while. Switched to Perfect Weight this summer and cannot believe how much more energy she has! She cleans EVERY bowl (maybe even faster than she did with her last food) and just all around a happier, more energetic dog! It took a few weeks to notice a weight difference but after that it just fell off and she is down to what our vet was wanting - so happy with Hill's! Should have switched her to this sooner!!!
