Questions & Answers

12 Customer Questions

Does this contain soy? I'm searching for an adult dry food bag that's Grain-Fee with no wheat, corn or say. Please advise.
Answer by ChewyAug 02, 2018
All of Diamond Naturals' recipes exclude corn, wheat and soy.

Does any of the ingredients come from China or any other countries???
Answer by ChewyAug 06, 2019
This formula is made in the United States but not all of the ingredients are sourced there. The Folic Acid is sourced in China, the Flax Seed and Barley are sourced in Canada, certain Potato Proteins are sourced in Germany, and the Chicory Root is sourced in Belgium.

A must try food!

My dogs have healthy coats and skin from this food but, one better reason is that I have a 10 year old dog with cancer and you could hardly tell. She has her bad days of course, but her general health is fabulous for having blood cancer. Her vet said for her age she is doing fabulous and to keep her on this food. I swear my dogs don't act their age. Still playful and rambunctious. I will only use Diamond grain free.

1 loved it 1 hated it

as our puppy is ending his days on puppy food we wanted something both of our dogs could enjoy and not have to buy two bags a months. We slowly switched both dogs into this food. about a month in we fully switched out younger bulldog has no issues with it, our older am staff had the worst poops and gas. for about 2 weeks was pooping in the house could hold it he is 8 and has never had this issue before this was all due to the food. We went right back to his old diet and the issues have stopped. I guess we are back to 2 bags a month of different foods.

Dogs are happy campers, that's what makes dad happy... currently out of stock but will buy more... expensive but healthy and worth it if you really loved your dog...

So happy I switched!

I’ll admit it, I am strangely obsessed with my Husky’s poops. I believe healthy poops = healthy dog. He had been on Hill’s prescription z/d dry dog food and his poops were disgusting. Soft, mushy, loose…I started reading the ingredient lists for dozens of dog foods and this food had the best ingredient list I had seen. It also didn’t contain any of the foods he’s allergic to and it’s about $65 cheaper per bag. He loves his new food, eats it regularly even though he’s picky. His poops are all formed now, I’m noticing he is scratching a little less, I’m hoping this will improve more with time. All in all I’m extremely happy with this food and highly recommend it.

dog not a fan

I wanted to switch my dogs food to something more healthier for her. But she doesn’t like this flavor I’m guessing. She spits it back out on the floor. I guess have to switch her back to proplan.

So far so good

We have used and like the regular Diamond dog food and decided to upgrade to the grain free. Everything seems good, dogs seem to like it. Solid poops.

Great buy, Will by again.

My dogs really liked the chicken & sweet potato formula. I like that it came in a smaller size.
