My dog is allergic to chicken.. does this have any chicken, chicken meal, chicken fat etc in it at all?

Answer by ChewyJul 24, 2019
This recipe contains chicken fat and chicken liver flavor.

What's the difference between Large Breed and the regular Science Diet Lamb and Rice, is it just bigger kibble or different nutrients?

Answer by ChewyMay 29, 2020
These 2 diets are essentially the same when it comes to the ingredients. The Hill's Science Diet Adult Large Breed Lamb Meal & Brown Rice Dry Dog Food has natural sources of glucosamine & chondroitin for joint health for large and giant breeds. The Hill's Science Diet Adult Lamb Meal & Brown Rice Recipe Dry Dog Food is formulated with all breed sizes in mind. Their nourishing recipe is balanced to meet your pet’s needs, help maintain strong muscles and promote skin and coat health.

I would like to try the Lamb ad brown rice dog food. I don't want a 30lb bag at first. Do you have smaller bags for my dog to check it out?

Answer by ChewyOct 27, 2020
At this time, the Hill's Science Diet Adult Large Breed Lamb Meal & Brown Rice Dry Dog Food is only available in a 33 pound bag.

Are all the meat ingredients sourced from USDA inspected and passed animals?

Answer by ChewyAug 23, 2022
Hill's sources their meat products from processing plants that only process foods fit for human consumption. Hill's does not use any part of an animal that has not passed the USDA Food Safety and Inspection Service process.

Winston is very big- 140lbs and 4 yrs old. I want food that’s tailored to his size to support not just his general nutritional needs, but that would also support his bones and joints. Was hoping for a giant breed food, or even a giant breed senior dog food from Science Diet, but this is as close as you carry. I love this boy and want to give him the best shot at a healthy, pain free life. I trust Science Diet’s research and quality.

It was left in the middle of my driveway for the whole world to see.

If they had taken 12 more steps, they could’ve put it on my front porch where it would’ve been out of view of people driving by. As it was, it was in the middle

If they had taken 12 more steps, they could’ve put it on my front porch where it would’ve been out of view of people driving by. As it was, it was in the middle of the driveway and could’ve easily been taken. The food and the treats are perfect, but if they can’t figure out a way to put the box on my porch so it won’t get stolen, it’s rather irritating.

All my pets use science diet and I am sure that this flavor was fine. The food was not the issue. I needed to exchange it. Trying to find a fedex here is impossible

The smell was awful upon opening the bag, my dog still tried eating it but it made his stomach make so many noises and gave him diahrrea and vomiting so I had to toss most of it.

Digestive issues

My two dogs have been throwing up and other things. I have very slowly tried to wean them off their old food but it’s just not working.

My dogs did not like it.

Arrived very dusty. Like dog food was old. My dog did not like it. I have 3 Rottweilers. And I threw about 1/3-1/2 the dog food away daily.

I switched from Chicken based Kibble to something different, Bulldogs tend to be allergic (skin wise) to chicken products. And we have had 4 Bulldogs one Olde English Bulldogge. They didn’t get loose stools from the gradual switch over and skin fur has cleared up.

Our dog had been throwing up for a long time and vet hadn’t figured it out. He recommended Hills Science Diet Lamb and Brown Rice. No more throwing up!!!
