How many cups of food are in the 40lb bags?

Answer by ChewyFeb 05, 2018
There's approximately 160 cups of food in the 40 pound bag.

If I’m switching my dog from Diamond Naturals Large Breed Puppy Lamb & Rice to this food, should I mix it as if it’s a new food, or can I just switch?

Answer by ChewyOct 24, 2021
We recommend at least a 7 - 10 day transition before you begin feeding the new formula exclusively. Start by mixing 75% of the old diet with 25% of the new diet on Day 1 and Day 2. On Day 3 and Day 4, mix 50% of the old diet with 50% of the new diet. On Day 5 and Day 6, mix 25% of the old diet with 75% of the new diet. On the 7th day, you can feed the new formula exclusively. This allows your pet’s digestive system to smoothly adapt to the new food.

Wanted to love

Switched my dog from purina pro plan sensitive skin and stomach to this kibble and I really wanted to love it. That being said, immediately after being switched completely to diamond naturals my dog started having diarrhea. Over the next two weeks I tried to allow for some adjusting but the last day of my dog eating this food he was sick- vomiting, diarrhea, lethargy. The day I made the switch back to pro plan upset stomach was gone.

Snoots snubbed this one.

Harmony hated this food. She's a picky eater, that's true. However I have never seen her turn down a good so quickly. Even after adding our Three Sisters Barkery

Harmony hated this food. She's a picky eater, that's true. However I have never seen her turn down a good so quickly. Even after adding our Three Sisters Barkery liver powder or Zoomie Butter it was an absolute no.

great quality food, not too high in calories

i’ve got a collie/blue heeler mix who gets fat on air, i swear! we tried diet foods so she could have more, but her blood sugar would tank, higher calorie foods

i’ve got a collie/blue heeler mix who gets fat on air, i swear! we tried diet foods so she could have more, but her blood sugar would tank, higher calorie foods made her grumpy because she was hungry but couldn’t eat more without gaining weight. this is a great middle ground and she has been on it for 2+ years!

He eats it

Doc is a 185 pound English mastiff who is very picky about dry dog food. We supplement his diet with vegetables and fruit when he wants them. He also gets fresh

Doc is a 185 pound English mastiff who is very picky about dry dog food. We supplement his diet with vegetables and fruit when he wants them. He also gets fresh meats. He has eaten dry since a pup but he gets tired of it half way through the bag but so far he likes this flavor.

Super shiny coat!

I have always fed my black Lab Diamond dog food. He has always had an insanely shiny coat! A friend of mine had a black lab that was struggling with his dog food. He was then switched to this food and it solved all belly issues and saw his coat get so shiny and smooth ! Great food!

Love the size of the kibble, and the same quality of ingredients for a smooth transition for Ella from her puppy to adult food. Was a little sad that the bag is a smaller size then the puppy but still very happy! Ella seems to enjoy it everything about her new food choice.

Love the fact I never have to worry about running out of food, this brand and variety isn’t always available in my area, also love that I can adjust the dates and easily order anytime. Wish I would have used chewy years earlier

My dogs will eat it but not crazy about it. They don’t get sick from it. I think they look healthy. They don’t eat a lot of it like the other foods, but maybe that’s why they don’t get sick. I have a dobi. And Pyrenees mix.
