Would this be a good food for German Shepard’s and good for their hips and joints?
Answer by ChewyMay 26, 2018
This food is suitable for all large breed dogs, including a German Shepherd, and contains guaranteed levels of Glucosamine and Chondroitin to support joint health.

Where is it made
Answer by ChewyMar 30, 2019
This food is made in the United States.

How large are the pieces? Our dogs really only like smaller pieces, but we want to feed them the large breed formula since they are all between 65-115 lbs.
Answer by ChewyJul 03, 2019
The kibble for this formula has a flat disc shape that is similar to the size of a nickel.

How many cups of food are in the 40lb bags?
Answer by ChewyFeb 05, 2018
There's approximately 160 cups of food in the 40 pound bag.

bag torn in 2 different places upon delivery

This review is for the condition of the bag upon opening the chewy box. We love the food and our dog does very well on it. I do however wish that they would not send large, heavy, 40 pound bags of dog food in the same box as other smaller items that could have sharp edges to them or their packaging. The bag of dog food has two large tears in it. There was food all inside the box and I do not feel comfortable feeding it to my dog.

Formula causes GI Upset

Please before you order this product, check the recent reviews here and on other sites. My issue does not seem uncommon within the last month or so. I originally was using the large breed lamb puppy formula for our 4.5 month old puppy.. Was great until we opened the last bag we ordered and my puppy immediately had GI issues for several days. Ordered this because it's the same flavor and thought maybe the puppy formula was just a bad batch. This caused another round of GI upset in him. We ended up over the course of a week throwing away almost 60 pounds of this brand of dog food. We switched to a Purina large breed puppy formula and he was almost immediately fine. I also emailed Diamond Naturals with no response.

Happy with it

I have been feeling my setter the lamb and rice since 8 weeks old. I compared ingredients to other brands and this one it up there with the very expensive ones. So for quality and price point, you can't beat it. My breeder has been using this with their kennel for over a decade without issues.

Great dog food

I have a almost 2 year old GSD who when I returned from a vacation in December looked awful bald spots and red itchy skin. He had some issues before we left but it definitely got worse. Vet told me to try switch his food he was on Perina one pro plan for large dog. Switched his food to this and he looks amazing! Shiny coat and he loves it.

Great Food

We would buy the puppy formula from Diamond Naturals for our GSD so it was a no brainer to get this adult food now. Our almost 2 year old GSD has a mixed diet and this kibble has been great for him. Definitely recommend.

used to be great

My dog used to love this food. I’m not sure if the formula got changed but since my last purchase she doesn’t want anything to do with it.

Exactly what we needed!

We had our dogs on a grain-free diet, but at the information from our vet about grain-free and heart problems we decided to add some rice. However, we had to find something without corn because we are feeding two German Shepherds. So I looked and looked and found this food. It's corn free but has rice, and is healthy for our dogs! It also comes in a much bigger bag for cheaper than what we were buying, and our dogs LOVE it! I would definitely recommend this for owners looking for more natural ingredients in a big container :)

No complaints here!

I’ve been feeding my dogs Diamond Naturals for over 5 years without any issues.

Dogs didn’t like taste.

My non picky working dogs did not like this dog food at all. I’ll be changing my autoship!
