Is this cooked at high heat? If so, do you have any that isn't? I'm concerned about AGE's.

Neither of our dogs will eat it. After several tries we have even tried putting toppers and bone broth on it and they lick the toppers off and manage to get the bone broth but leave as much of the Diamond food as they can. We have tried multiple different dry dog foods over the years and our dogs have never seemed too picky but for some reason they just won’t touch this one.

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.

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.

Both my dog was battling really bad skin and coat after talking to the amazing Chewy crew the pointed me to a cheap but good food for my boys I have a senior German shepherd and a young Canis panther. They have only been on Diamond for a short time not fully on it still mixing their old food but I'm extremely happy with the results already alot less itching and skin flaking from my senior and my canis panther who is my life saver service dog who has alot less shedding and now has a beautiful shiny slik coat.
