Questions & Answers

I have older dogs two of which gain weight easily. Does senior food have less calories? They currently eat the regular of this brand and I have to keep cutting back.
Answer by ChewyNov 07, 2017
This Food contains 318 kilocalories per cup. The Diamond Naturals Large Breed Adult Chicken & Rice Formula Dry Dog Food contains 327 kilocalories per cup.

I am interested in this food for my senior pup. How many cups can I get per pound?
Answer by ChewyJun 25, 2018
There's approximately 24 cups of food in the 6 pound bag, 72 cups of food in the 18 pound bag, and 140 cups of food in the 35 pound bag.

What age do you consider senior for this food?
Answer by ChewyNov 05, 2017
Senior formulas should be given to pet's that are at least 7 years old.

Is the guaranteed analysis measeured by kg? Then a serving size is mesured in cups. If I save my senior dog one cup a day how much glucosamine and chondroitin would he be consuming a day?
Answer by ChewyApr 01, 2018
The guaranteed analysis of the food goes mostly by milligrams and one cup serving. If one cup is served then your dog would get 720 mg/kg min of Glucosamine and 240 mg/kg min of Chondroitin.

I fed this to my dogs for over two years, their fur became dull and fell out like never before! The skin issues it was being fed to them for never went away or lessened. Nor did I see any benefits to their joint health and or increase in energy levels. Now that I know what “chicken meal” can mean….beaks, feathers and whatever other garbage by product they want to throw in the mix. This food did not help my dogs. Actually made them VERY GASSY. I have begun to make my own food and my dog has never looked better. Sadly, my other guy passed before he could reap the benefits of home cooked food and fresh ingredients!

Not a fan of this food

The vet said I needed to put my 10yr old on a mature food. I’ve been feeding all my dogs the same kind but regular food. None of my dogs will even eat this little alone the one it was meant for. My youngest dog will eat anything and always steals my oldest dogs food. Even when it’s the same food she has. Not this one. 3 dogs and two cats and no one is touching it.

Dogs would not eat it

Unfortunately our 2 older dogs would not eat this food. They usually are not picky eaters. After a month they had only consumed about 10 lbs, normal they would eat at least twice that much. Product may be very good but just not for my dogs. Had to give away remaining 25 lbs.

Great food for the price

I was needing to find a less expensive food, after looking at the ingredients, I had to try this food. It was comparable to the expensive brand I have been feeding. All 4 of my dogs have transitioned great to this food. The kibble is the perfect size as well. Great quality food for the size and price. So glad I found this food!

My 8 yr old dog likes it!

I’ve only had this food for 2 days but my dog REALLY likes it. I live in an apartment and this was delivered on the stairs. When I went to go let my dog out to go potty, he didn’t even want to leave the stairs bc he couldn’t stop smelling the box with the food in it lol! I will do my best to review this again in a couple months (:

Not a winner

My dogs have been eating diamond naturals for a few years. But due to the amount of corn in the last variety I switched to this and my dogs don't like it one bit. They don't even want to touch it. The only way I can get them to eat it is by covering it in beef broth.

Blu Approved

This is the 4th bag I’ve bought. my dog was losing weight with the last brand but once I began feeding her Diamond naturals she has remained the same weight and my dog still gets her bursts of energy while outside.

Don't buy! Goes right through my dog

Although my dog likes it, she produces MUCH more waste than before. I combined it with her previous food because I bought such a big bag and didn't want to waste it.

what a difference a week makes

After eating this food for a week millie has stopped licking her paw and her eyes have cleared up. This food is most definitely on auto delivery. Glad I found it for her thanks chewy!

Good service

I made the order I needed for my pitbull. Unlike other outlets, my order arrived within the time I expected, which was right in time it was needed.
