Questions & Answers

8 Customer Questions

Can this be fed to puppies also?
Answer by ChewyMar 20, 2022
This food is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for All Life Stages including the growth of large size dogs (70 pounds or more as an adult).

How many cups per bag?
Answer by ChewyJul 07, 2018
There will be approximately 4 cups per pound of kibble. The 8 pound bag will have close to 32 cups, the 20 pound bag close to 80 cups and the 40 pound bag close to 160 cups.

Are the probiotics added to the kibble before cooking? What percent of probiotics are still viable after cooking?
Answer by ChewySep 12, 2018
Probiotics are added to the food after the cooking process so the beneficial bacteria are not killed. Every pound of Diamond Pet Foods is guaranteed to provide 80,000,000 colony-forming units (CFU) of live, active probiotic cultures.

Does it have corn gluten in it or any kind of corn?
Answer by ChewyOct 28, 2018
This food contains Whole Grain Ground Corn.

Good food for the cost and nutrition

I have been feeding my 1.7 year old Auggie exclusively Diamond brand products. I recently had to throw away the Kirkland Small Breed Salmon and Lentil (made by Diamond) formula due to the her skin started to smell like fish. This tells me that the product is very effective. I just couldn't stand the smell of fish on her. So I switched her to this. It is heavier in grain but there are only two types of grain: corn and wheat. Not bad. She devoured it. She's a an incredibly active dog. She runs with me almost every morning. Last week we ran a 10 miler! She's normally picky with her food, but this she devoured. I can feed her higher in carbs since she is a very active dog. The added 80 million CFUs per lb. is a definite plus which reduces gastro upset and also possible allergic or immune system issues. Highly recommended for active dogs due to the higher carb percentage. Most importantly, the price is awesome.

Best Food Donated to Local No Kill Shelter

I adopted a shelter dog this summer and this is the food they gave me to take home. This is recommended for high-energy herding dogs, which mine is--and she seems to do well on this brand.

Best food

We have tried all types of Diamond food when our local bet store stopped carrying this exact one. Our LabradoodleS belly can only handle this exact one. Chewy came through. Amen!

Torn bag of dog food

Hello this is a first for us but I think you should know. Our regular order of three bags of dry food had a mishap during delivery, one of the bags was mishandled and tore open during its enroute to us it emptied about almost half of its contents into the delivery box which leaked out while it was in transit please be aware of this for the future delivery! Thank you

High Quality dog food!

I'll admit there are other brands out there that have a bag that LOOKS better, but it's what's inside the bag that counts! I give this to my GSP and he has the softest, shiniest coat ever. It gives him nice hard poops that are easy to clean up as well.

Bad Stomach Issues

I would give this 0 stars if I could. I was really excited to give this food a try and my dog seemed interested in it. He can be a picky eater, so I gave him maybe five pieces to try and the next morning he had an extremely upset stomach. I thought it might be something else he ate so I waited a few days and gave him maybe three pieces of food and again he had an extremely upset stomach shortly after. Definitely can NOT recommend this.
