When transitioning your pet to a new food, we recommend a gradual introduction of the new formula over a 7 day period. For pets with sensitivities, extend the transition period to 10 to 14 days. Start by adding a small amount of your pet’s new food to his or her current food. Gradually, increase the new food amount and decrease the current food amount at each feeding until you are feeding only the new food.

Uncompromising Holistic Nutrition
Diamond Naturals dog food provides high-quality holistic formulas designed to meet every pet's needs. These nutritious recipes are enhanced with proprietary probiotics for good digestion and immune system support, and superfoods are added to supply nutrients that keep animals strong and healthy.
Superfoods That Deliver
They didn't just add a few superfoods here and there in Diamond Naturals. You'll find 10-20% superfoods in all Diamond Naturals dry foods, made up of tasty ingredients like kale, blueberries, chia seeds, pumpkin, quinoa, coconut and spinach.

Balanced Digestive Support
Foods with added probiotics allow more nutrients to be absorbed and used by your dog's body, and that leads to better digestion and overall health. Diamond Naturals foods are enhanced with patented and powerful K9 Strain probiotics. Prebiotic fiber from chicory root plus soluble and insoluble fibers from pumpkin, coconut and dried kelp give extra digestive support.
Really Delicious Real Proteins
Made with real beef, lamb or chicken, Diamond Naturals dog food satisfies carnivorous cravings meal after meal. These nutritious animal proteins have the essential amino acids your dog needs to keep running, playing, jumping and staying fit. High-quality proteins like these are the building blocks of healthy muscles and strong bones.


Options for Sensitive Pets
All of Diamond Naturals' recipes exclude corn, wheat and soy, common fillers that are used in pet foods. If your dog is sensitive to this trio of ingredients, there's no need to worry when feeding Diamond Naturals. And for pups that have problems digesting grains, Diamond Naturals Grain-Free dog kibble is a great option for limiting exposure to these ingredients.
Don't Forget the Treats
When you want to reward your pup with a tasty treat, give him a Diamond Naturals biscuit. These crunchy bite-size snacks feature real lamb, chicken, beef or peanut butter plus whole flaxseed, rolled oats, turmeric and brown rice. They're all free of corn, wheat and soy, and they come in Large Breed with added glucosamine and Puppy biscuits that are smaller for tiny mouths.

Great product!
By KJackson on Jan 12, 2021
I have a 10 month old American Bully and have been feeding her Hills since we got her. She has had some allergy issues and recently has been avoiding her food so we switched to Diamond Naturals. My dog loves this! She had no stomach issues when switching and her coat has become more shiny. She is no longer itchy like before. We will continue to buy this because she eats it and the price is great! I like that there are different flavor choices because I’m slightly convinced my dog doesn’t tolerate chicken well.

Not sure yet
By AGold on Jan 18, 2021
This is the 3rd dog food I have tried with my 14 week old pit puppies. It’s been almost 2weeks and I am about to lose my mind with the continuous large stools. They don’t act like they r in love with the food either but they haven’t acted like they loved science diet or blue Buffalo either. They had more normal stools with the blue Buffalo. Just not ready to throw the bag in yet and move on to a 4th type.

Bummer it didn't work for us.
By flhr on Dec 22, 2020
After lots of research I thought this as going to be a great food for my German Shepherd puppy. After 2 x 40 pound bags and many soft and loose stools I had to give in. I switched to Purina Pro Plan Large Breed Puppy which is a chicken based product and within a few days everything was normal. I'm not sure what the issue was, but it probably could use more fiber. I added fiber to the Diamond Naturals and it helped, but the directions recommend so much food and adding fiber made it always an emergency when my puppy had to go out. The volume was huge. I had high hopes and many people rave about this food, maybe start with a small bag.

Dog doesn't care for this food
By Kara on Dec 13, 2020
Our vet recommended that we find a large breed puppy food rather than the puppy food we were feeding our 12 week old Great Dane. We picked this because our other dog (3 year old yellow lab) has food allergies but loves to steal kibble that the little one throws out of her crate while eating. This was the only large breed puppy food that was lamb based with only a small amount of other protein source. Unfortunately, our Great Dane won't eat this without mixing in toppers or wet food to entice her. She also has started trying to steal the older dog's food, so we know she's hungry! This food is harder for her to bite than the previous food, so it's either the texture or the smell that she isn't Our vet recommended that we find a large breed puppy food rather than the puppy food we were feeding our 12 week old Great Dane.

Nutritious and Economical
By Review on Jan 19, 2021
This dog includes salmon oil and is nutritionally sound for my large puppy, pyredoodle. She loves it. AND it's the best price for this level of nutrition. Everything that I read suggests salmon oil for her skin but she did not like her last food that was salmon flavored. She loves this lamb flavor and still gets the nutrients she needs.

Puppy seems to like it!
By Diane on Jan 13, 2021
He likes it better than the Blue large breed puppy food, so I guess that a good thing. But, he still doesn’t LOVE it. Maybe i’s him...lol. A 4month old Great Pyr. The food smells good and I like the ingredients so I will be sticking with this one until he is 2. Price seems fair too.

No more soft stools!
By Stella on Dec 27, 2020
I could not get my pup to have firm stools, I called the breeder for a recommendation and was told my pups mother was just switched to Diamond Naturals because of the change in her stools. After a few weeks on Diamond Naturals Stella is doing great and I’m happy. (Easier cleanup in the yard!!).

diamond large puppy lamb
By Millissa on Dec 15, 2020
We have four large kids and we mix this with another adult kibble and they love it. It helped us since we have multiple allergies in our pack. Cherry has always been helpful and understanding. We tried cheaper brands and that didn’t not work. We will be sticking with this as their coats are soft and smooth, they are energetic, poo is solid, and they look forward to eating. Thank you chewy

She loves and AAFCO recommend
By BoPeep on Jan 10, 2021
My Bernese mountain dog mixed with a golden doodle loves her food! She’s three months old and nice and healthy. After researching I found this to be rated 5 out of 5 stars for large breed puppy foods by the AFFCO and enthusiastically recommend. Great buy!

Hallelujah my dog likes it and didn't get diarrhea
By TimTamSlam on Nov 12, 2020 Top 500 Contributor
I went through about 5 different dog foods until I got to this one but my dog likes it and it didn't make him sick. I'm so happy I finally figured out what to feed him. I bought a more expensive brand of puppy food with this bag and had him taste test the two and I'm very happy to report he picked this one because it is a lot more affordable. I tested him three different times and he picked this one over the expensive one everytime. And he's been on it for about three days and his poo is pretty solid. Which is great because another food we tried before he loved the taste of but it gave him raging diarrhea. So happy he picked an affordable quality option and his poo is solid. Hallelujah.
