I have been feeding this food to my great Danes for 10 years and it is a great dry dog food. My dogs look amazing. I highly recommend it.

  • Good price and dogs love it
Flavor Name: Chicken Size: 40 Pound (Pack of 1)
When this is available, it’s what I get for my great Pyrenees and Australian Shepherd. They really like it and prefer it over any of the brands that I’ve had to get from any of the local big pet stores or box stores.

  • Best food for picky eaters
Flavor Name: Chicken Size: 40 Pound (Pack of 1)
I was using Royal Canin before but it was getting to expensive so I found this one and my dogs love it more it seems like. One of my dogs is very picky when it comes to food and she'll rat this one right up every time.

  • Natural, Healthy, Priced right!
Flavor Name: Chicken Size: 40 Pound (Pack of 1)
Had to get this vs the normal Diamond Naturals as Amazon ran out of stock... Amazon actually refunded me the difference RIGHT AWAY, which again, blows my mind in their customer service. They never argue with you, and just solve your problem with no questions asked. This is why I always buy as much as I can from Amazon, you cant beat the customer service. Again this dog food brand is awesome, I love the ingredients, my dogs poop (yeah I know gross) is awesome - firm and always solid. I actually like this one with the bigger kibble, plus I have an akita so the extra joint supplements I am sure help as well. As with most food my dog chows it down like no other. If your looking for a healthy well priced bag of dog food, go with ANY Diamond Natural Food. This goes for cats as well, our cats love their food. ... show more
