Questions & Answers

21 Customer Questions

When will it be back in stock

What kind of whitefish does this food contain?
Answer by ChewyMar 26, 2018
The whitefish is an Ocean blend of Hake, Pollock, Cod, and Sole. It is a different mix of Ocean fish depending on the time of year and the catching seasons. All fish either are from Alaskan waters (Grand Banks), or caught off the Atlantic Ocean.

Are all ingredients sourced in the US?
Answer by ChewyMay 07, 2018
Not all of the ingredients in this Formula are sourced in the United States. The Folic Acid is sourced in China, the Flax Seed and Barley are sourced in Canada, certain Potato Protein is sourced in Germany, and the Chicory Root is sourced in Belgium.

Does this food have a fish smell
Answer by ChewyMay 30, 2018

Do not buy

Terrible food, made my dog sick, gave her ear problems, didn't know what it was till I finally switched foods. Vet told me this brand has a long history of recalls. DO NOT BUY

Son's suggestion

I was caring for my son's dog last week and took a look at the ingredients from the food he had for him. It had no preservatives and all "real" ingredients. He told me he ordered it from Chewy. I got right home, ordered it, and it came so quickly it surprised me. Thank you for selling great products and delivering so speedily!!

Had trouble with this one

I couldn't get the Diamond Naturals Skin and Coat Formula with salmon and I tried to substitute with this Diamond Naturals with whitefish. Both are grain free. Anyway, this formula made my mini schnauzer sick. My lab doesn't seem to care much about food of any kind. She's indifferent to both, but so far hasn't gotten sick. Can't figure out what the difference would be, but he can't digest this one.

She likes it.

This product seems to have helped with itchiness. Got fast shipping and a good price.

Good food for my dog that has Gerds.

Bought this for my Golden Retriever that has gerds and this seems to be helping. I do however find that getting this food to be in stock is an issue. I just hope as time goes on it will be more available.

Ummmm...No. Just "No"

My husky has more allergies than things she CAN eat. Fish is her least offensive. She wouldn't touch it. The labradoodle gobbles it down! "Give it til Micah~he'll eat ANYthing." But since he has been he has horrible flatus! It apparently bothers him too. He sniffs, looks around and leaves the area. I fully support Diamond Naturals but just not THIS one for MY furbabies.

Sensitivities friendly

This seems to be a good food for my boy who has a very sensitive stomach. Glad to find something that does not promote constant soft stools or diarrhea in him.

Another Diamond Winner!

I have preferred Diamond kibbled food for many years. This formula seems to appeal to my picky poodle. Diamond adds a big variety of good real food items to their formulas along with the vitamins and minerals that experts recommend. I appreciate food that isn't exclusively chemicals.
