Questions & Answers

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.

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.

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!

excellent kibble

This food checks a lot of boxes for me. It’s highly rated on dog food advisor for quality of ingredients. I really like the size and shape of the kibble for my three large dogs. (I’d been giving my dogs Victor for years, but never liked the small kibble size.) It’s chicken instead of beef. The price is great. The dogs don’t have gas and produce quality poop. I’m very happy we switched to this food.

FOOD GREAT DELIVERY NOT SO GOOD

Driver picked up 2 40lbs boxes of dog food and dropped at our front door i box split open and bag burst. We needed the food aas we were out so cleaned up mess and our dog is happy. Driver was trying to cut corners by lifting 2 boxes instead of making 2 trips

Started on this food

My weimaraner has been on this brand from the beginning. First puppy large breed then the adult. He has a fairly sensitive stomach and this food acts as a great base to add wet food, boiled chicken etc.

New favorite

Our dog has been on Diamond Natural chicken and rice since puppyhood. Decided to try the large breed version now he’s grown into his 100# self. It was an easy transition. He likes it and no digestive upsets.

Not for us

First off, my dogs did like this brand. They aren't picky eaters but one of them has a sensitivity to beef so I can only buy poultry flavored foods. I gave it 3 stars because I wasn't a fan of the size of the kibble pieces (I prefer smaller pieces), but also it gave my dogs nasty gas. I would still recommend this product however. They have good ratings on Dog Food Advisor.

its a good option but

Our dogs got bored and uninterested. We tried all the flavors & they just weren’t excited to eat after the first couple days. We switched to diamond pro & they loved it. So diamond is definitely our brand.

dogs dont like this brand

thought the dogs would like this, I am searching for a food that is healthy and the dogs like. this brand is supposed to be healthy but the dogs do not eat it unless they are starving, they have lost weight and I am on the hunt still for that perfect dog food

Large Pieces

My huge dog eats too fast! The large pieces slow him down a tiny bit and Diamond Naturals has good quality ingredients. Seems to digest well and doesn't cause gas. Just wish it came in a smaller weight bag.
