Are the manufacturing facilities in the USA?
Answer by ChewyFeb 28, 2018
All Diamond formulas are manufactured under rigorous production standards in Diamond’s state-of-the-art U.S. facilities.

Are all ingredients used to make this food from the usa? And if not where are they from?
Answer by ChewyFeb 27, 2018
This formula uses some ingredients that are not USA sourced, like flaxseed and barley, both which originate in Canada and lamb and lamb meal from New Zealand and Australia, potato protein from Germany and dried chicory root from Belgium. There are ingredients such as folic acid and taurine that can only be sourced out of China.

why the does your food have Papaya in it.
Answer by ChewyJul 04, 2018
Papaya and papaya enzymes are healthy ingredients to add to dog food. Papaya adds sweetness as well as vitamins and fiber to a dog's meal.

How many cup is in the 6lb bag?
Answer by ChewyApr 14, 2018
There will be approximately 4 cups per pound of kibble. The 6 pound bag will have close to 24 cups, the 20 pound bag close to 80 cups and the 40 pound bag close to 160 cups.

Best food I’ve found

Shepherds are famous for grain intolerance and my puppy Bailey is no different. She is 6 months old and growing like a weed. It’s super important that she gets large breed puppy food to support her growing bones etc. I spent a LONG TIME reading nutrition labels. This is the ONLY food I found that fit all of my criteria: high protein, grain free, large breed specific, probiotics included. The cherry on top: SHE LOVES IT!! She is skinny because she’s super hyper so I feed her 3x day for now. I will definitely stick with this brand forever.

Great for chicken allergies

Great for chicken allergies I didnt even know that was a thing until we got our great Pyrenees and trying to find food that doesnt have chicken meal or some sort of chicken is very difficult and when you do find it its extremely expensive

Great Value

This food is rated very highly on dogfoodadvisor and it's priced very well here on Chewy. Everything else I buy on Chewy revolves around my ability to buy this brand of food at this price.

Such awesome service!

So grateful to Chewy - I’m an at-home caregiver, & it’s difficult for me to get out & run errands. Recently got a new pup who is training to become a support dog for my husband. A very busy time! It means so much that Chewy makes getting food this easy! Thank you, Chewy! You’re the best!

Great puppy food

Diamond puppy food for large breed dogs has been good for our pointing lab puppies, Cocoa-18 mths; Rose-1 yr in Sep; Gracie-1 yr in Oct & Duke-yr old in Nov. The dogs are growing well & nice shiny coats. They love feeding time!

Puppy loves it

Recently adopted a 4 month old Great Pyrenees mix puppy from a rescue. They had been feeding Diamond Natural food to all the rescue dogs. To make the transition easy on the pup we kept to the same food adding in some veggies that we feed our other dogs. She loves it. The other positive about this brand is it is made in the USA.

Why so tiny?

I recently transitioned dog foods and thought I would give Diamond a try. When ordering a “large breed” or “small breed” style of dog food, I tend to believe the size of the dog kibble will be proportional to the size of the dog intended to eat said food. That does not seem to be the case with Diamond Naturals Large Breed Puppy Formula. My 9# chihuahua’s dog kibble is surprisingly similar in size to Diamond’s Large Breed Puppy kibble, which I feed to a 100# Bernese Mountain Dog puppy. I don’t understand the reasoning behind such a miniature sized kibble intended for large dogs. Why so tiny?

Northern Inuit puppy likes it!

This seems like a solid kibble choice for large breed puppy with sensitive tummy based on the recommendations of reputable breeders. It is also less pricy than Orijen. We haven’t completely transition from Orijen/Purina One plus Large Breed puppy food but he definitely likes it so far! Plus lamb is such a good protein to add to puppy’s diet. I do wish kibble size is a little bigger similar to Orijen/Purina so it’s easier for younger puppies. See photos below as comparisons (Purina->Orijen->Diamond Naturals). Diamond Nature’s kibble size is about the size of a popcorn kernel.
