Questions & Answers

42 Customer Questions


What is in large breed food that is not in an all size food? What makes it better for large breeds?
Answer by ChewyJul 26, 2018
Large breed formulas tend to have higher concentration of glucosamine and chondroitin sulfate which help develop the cartilage and bone. They also tend to have leaner proteins for strong muscle development to help support the larger frames.

Kitchen location?
Answer by ChewyJul 25, 2017
Diamond has five manufacturing facilities, all located in the United States. Two facilities are located in California, and the others are located in Missouri, South Carolina, and Arkansas.

How big is the kibble? I have a 9 week old bullmastiff my vet wants me to start her on large breed adult so I don't want something too big, will be an acceptable kibble
Answer by ChewyJun 10, 2021
This formula has kibble shaped like a flat, round disk, approximately the size of a dime.

How can I determine how many 5 cup servings can be expected in a bag of 40 lb.?
Answer by ChewyApr 03, 2018
There's approximately 160 cups of food in the 40 pound bag.

Switched to Diamond Natural dog food

We were using "Gentle Giant" dog food for our Great Dane and Standard Poodle the past several years, and it is a good product. But we just tried Diamond Naturals" dog food and our dogs love it. But also, our Great Dante's poop was always soft to runny at times. With Diamond Natural his poop is now firm and on a normal schedule. So I feel Diamond Natural has been a better food for our dogs digestive system. Also, it is a better value since it comes in 40 lb. bags for about the same price we were paying for Gentle Giants 33 lb. bags. A win-win all the way around!

Often Out of stock/Potential Price Increase

My 14 month old German Shepard Buddy loves this brand. It especially helps him with his sensitive stomach, the prebiotics and probiotics in this formula help him digest easily and helps him produce healthy hard doggy stool. Mango has been on this formula since April this year 2022 and it is now September 23 2022 and the price increased from $30.99 to $43.99. This is a great formula to try out if your large breed fur baby has a sensitive tummy. The size of the kibbles are round disc shapes and almost the size of quarters. Pretty decent sizes for large and xtra large breeds. It seems to be popular because this brand tends to go out of stock often. The scent of this brand of kibbles actually smells of great quality, it does not make your nose turn up and away. I highly recommend to give this a try.

Good All Around Dog Food for Big Dogs

We were getting 2 kinds of dog food - One for our aging lab and one for our younger golden retriever. This dog food hit the marks for both dogs, and is a great mid-priced dog food for them both.

Unlike the other products by this brand

I had originally started my big pit mix rescue on the diamond naturals skin and coat formula, which he loved. The kibble pellets were small, ball shaped, they fit in a slow feeder toy that he loves, and it was a good smell, as far as a dog is concerned. But when I got our boxer pup, who also ended up being over 90 pounds, I decided to go ahead and switch them both over to a large breed food when I switched the boxer off of his puppy food. The Diamond large breed formulas are completely different, both lamb and chicken. The kibbles disc-like, much bigger and flatter, they’re lighter in color, which I don’t know if that makes a difference, they dont seem as dense, and they don’t seem to have much smell either. It must be a little like eating cardboard pellets. Even the rescue, who will literally eat anything, will actually leave breakfast until dinner and then finally eat it. He never does that! So sadly I’ve had to start looking for another brand.

Dog likes it

One week into adult dog food. She's been on Diamond Naturals since weening. Seems to enjoy the flavor and larger chunks. I'm happy with the brand.

One food for all 12 dogs.

My sister and I were on the hunt for a good dog food that could be used for all 12 of our dogs. After looking at various foods we both opted for Diamond Naturals. She tried it first with her dogs and after 2 weeks gave glowing reports about how her dogs were both liking and doing great on the new food. She has a couple of dogs with sensitive digestive systems and can only use chicken formulas. I have large dogs that can eat anything but one that tends to put extra weight on easily. I switched shortly after she did and all 12 dogs are doing great on this food. I would highly recommend it!

One bad out of a lot good

Orders are usually really timely so that’s a huge plus. But this last bag had a huge hole in it and the the box was full of kibble. But usually they’re great.

Did the formula change

This is my 2 bag from here plus I bought 2 bags from our local store before I started ordering from Chewy. We wanted to make sure he would eat this brand and flavor. This last bag he will not eat. We have tried different foods to mix it with it and wouldn't touch it. Today I added eggs and he ate his dinner. I guess that is what I will do for each meal but I am afraid to order another bag. Last bags the food was a lighter brown and this bag is a darker brown.

Danes love it.

Have tried a few different brands of large breed bags of food and this one seems to agree with both our Great Danes stomachs.
