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.

My dogs eat it.

I have my Chewy who is very very picky, he eats it plain. That in itself is a miracle. My two rotties, Menace and Zena also eat it. So now I just order this instead

Our dog won't touch this

I'm not sure whether it was lamb that our dog didn't like or just Science Diet's lamb. We tried adding other foods he loves to this kibble, but he carefully removed

I'm not sure whether it was lamb that our dog didn't like or just Science Diet's lamb. We tried adding other foods he loves to this kibble, but he carefully removed each kibble chunk from the bowl and ate the yummy toppers. Maybe these were too hard to chew?

Lamb for large dogs

Why is it so hard to find lamb for large dogs?Anyways, my vet recommended me this brand. We used to do sensitive stomach chicken. then tada, allergic to chicken

Why is it so hard to find lamb for large dogs?Anyways, my vet recommended me this brand. We used to do sensitive stomach chicken. then tada, allergic to chicken like he is everything else. So, lamb it is. We tried fish and everything it’s a NO. He loves this! Anything he likes he gets! His hair is back and his stomach problems are so much better. But I will remind everyone this brand has for large breed, so large kibble. Thank god bc other brands do not. I have a RR and they wonderful but have sensitive skin and stomach. If your dog sensitive and chicken is a no this is a go.

Dogs' favorite

We switch between flavors, and all three dogs like the lamb meal and rice the best. One dog has allergies and a sensitive stomach, but she can eat this without any

Made my dog sick

Usually Hill's Science Diet food has been great for my dog. She's going on 2 years old. She's half Border Collie & half St Bernard, so she's 111 lbs. She Loved

Usually Hill's Science Diet food has been great for my dog. She's going on 2 years old. She's half Border Collie & half St Bernard, so she's 111 lbs. She Loved the weight management food. But, just found out she may be allergic to chicken, so I had to switch foods. I ordered the Lamb Meal & Brown Rice and my dog kept throwing it up. Hope it's good for other dogs. I'm very sad that I have to change brands completely, but they don't have any other flavors. Trying Gentle Giants because of the great reviews. I still recommend Hill's Science Diet, just didn't have a good experience with this flavor.
