Make the switch was worth it!

My dogs love that food and we love it too because it's good for them. We initially had them on the highly active version but it was time to make the change to moderately since they are older now. We love the Diamond brand for their wonderful products but for the cost too. Our dogs are happy and so are we.

I believe that they were taken reported to Fedex.

I love chewy I wish that you worked with somebody besides Fedex. This is the second or third time that my shipment has been stolen because leaves it at the street

I love chewy I wish that you worked with somebody besides Fedex. This is the second or third time that my shipment has been stolen because leaves it at the street instead of in a package locker that is right there so I’m gonna need to place the order again because I did not get the order that I need

It says dog was delivered. It is nowhere to be found. So I can only assume it was not delivered. The photo that was taken and there was no house, trailer, anything distinctive in the photo. It could have been taken from Anywhere. I request a new delivery.

Have used this brand for 15+ years, but my girls were getting tired of the salmon so I moved to the maintenance chicken because I’ve got senior dogs who are active still and they like the taste of it. They’re eating their full bowls now.

Good quality food at a reasonable price

I've used this food for years. All the dogs like it and all our staying very healthy. I hate the new bags. The seams of the bag on top are not as strong as the old bags and several times the seam has broken causing me to drop the bag. It's definitely an inconvenience to stack the extra bags, but fortunately none of the bags broke after falling. The other problem I have is the boxes they ship in. They are bulky and obviously heavy with no way to grab them easily. If Chewy could simply have boxes with a hole cut out on two sides, it would make things so much easier for everyone. The food itself gets 5 stars, but the shipping and moving problems bring it down to 4 stars. I would absolute recommend this food even with the issues described.

We have a Rough Collie and I have struggled finding her a food that her stomach agrees with. I previously had her on the Dimond Premium but her poops were still runny and unpredictable. I switched her to the maintenance and her skin / cote looks much healthier, and her poops are nice and solid on a consistent basis. I highly recommend this food for dogs with sensitive stomachs.

I've fed Diamond for a long time. Both of my dogs get it. For the price point it is the best food available in my opinion. Comparable to some brands that are far more expensive when comparing labels.
