Switched over to Diamond originally for our German Shepherd puppy. We had him on Blue Buffalo but the food was too rich and he always had runny #2's. He also had a lot of dandruff which we think may have been caused by a chicken allergy, which is very common. Since he did so well on it we decided to switch our cat over because it was very affordable. Our Bengal does not eat a lot so we keep the food in a sealed storage container. It keeps the food very fresh and for much longer, so if you have picky pets, ask yourself if you would eat stale month old food that has been sitting out lol. There are always people complaining about their dogs or cats having diarrhea. I really feel like people need to be more educated on how to switch to a new food as well as the time involved. 1) Every animal just like every person is different and some animals could eat a different brand and flavor every day and never have an upset stomach. Some do better with a changing, varied diet while others are better off with the same food and no interruptions. Age, breed, temperament, environment, and pretty much everything else you could think of all play a part. 2) Switching to a new food varies but it is usually suggested that the slower you acclimate them the better. Assuming I did not wait until the last minute and have planned for the change I will start by replacing 10% of the old food with the new food (rough estimate, I am not counting kibble) and then every day I will replace another 10%. Total acclimation of about 10 days, it's really not that hard so stop being lazy. If I notice my pet is not adjusting well or has an upset stomach I will generally go back to the previous day's mixture, when they were feeling well. 3) Even if you slowly acclimate them to a new food it can take a couple weeks for their stomachs to get back to normal. This is especially true with younger animals. I see people giving good foods 1 star reviews because their 10 week old puppy had diarrhea for a week...get real. Before you get the pitchforks out I am not saying that everyone should just ignore their pet that's having some stomach problems for four weeks. I am just saying I think there are a lot of nut-job pet owner's out there that claim a food is poison because their dog didn't do well on it. It takes time to adjust even if you do it right. In some cases it just doesn't work out, like my German Shepherd on Blue Buffalo. They have great quality food and I would still recommend them to people but for the couple puppies I have had on it, it seemed to be a little too rich/pure. They did better with the natural foods that had a little more filler like Diamond.

I've been using Diamond Naturals since 1997. I've always owned large dogs so the formulas I've used the most have been Large Breed Puppy and the Adult formulas including Adult Large Breed. Due to an increase of chicken allergies over the years I tend to stick with Salmon or Lamb. I currently give my Adult dogs the Lamb. I've never had an issue over the years with any deficiencies in my dogs related to nutrition and I've never had this recalled over any sort of contamination. Years ago I used Iams, and they did have a recall. I know stuff can happen but I'm pleased with Diamond. I can usually find it TSC, Rural King, Petco and a few other places as well. I work with dogs and anytime I have my animals out people always ask what I feed them and compliment the dogs. My primary breeds over these couple of decades have been St. Bernards, AmStaff and Doberman. This food has served them all well. I will always recommend this brand until I have a reason not to. I feel it's a good middle ground food for anyone who wants to feed their dog the best they can without breaking the bank. It is costly but not like many of the brands and you can feel good that you're not feeding Ol Roy type quality food. I've occasionally taken on foster dogs and I actually had a puppy with knuckling, this food helped correct that condition. I currently have 2 puppies less than 3 months old on this food and they are gaining weight at a rate of 3.5lbs a week. The kibble is easy for them to eat and easy to digest. I can always tell my dogs poo from other dogs when we are on walks, traveling or stop at a park. It makes clean up so much easier too. A 40lb bag of the adult usually last my 2 adult dogs 2.5 weeks. They are 80/90 something lb dogs. I'm only on my first bag of puppy food so I can't say for certain how long the 40lb bag last for 2 large breed puppies. It's been years since I had dogs this young. Best I can remember, the 40 lb puppy bag lasted a month. All of those factors depend greatly on the breed you have and their weight. Hopefully this will give you the general idea. My vet knows the food I use and approved of it. For me, it's a 10 out 10. Like everything else, I have watched the price of this go up over the years. I used to pay like $35 for the same size bags. The puppy formula does cost a bit more than the adult formula. That seems common across any brands. Give this food a try, I really don't see you regretting it. Our Doberman all have nice sheen to their coats. We have reds and we have blacks. Oh, Amazon also got this shipped out to me quickly.

Our pup was having stomach issues. We tried this out and he’s doing great. Just inspect your shipment right away, one of our bags came tapped shut on the side so we threw it away to be safe.

Anyone that has ever had a GSD knows how hard it is to get weight on them while they are growing, especially if they are really active. It's not uncommon for them to look like they are starving even when they eat the entire house (Ribs showing type scenario). After lots of research and pricing, I settled on Diamond Natural Large Puppy. My GSD pup was around 4 months old and pretty underweight when I rescued her. She had been really sick with a parasite, on top of that, so we had some real work to do to get her healthy. I increased her food amount nearly a cup and a half a day over the recommended serving size for her age for about a month and she gained nicely! Once she was no longer showing ribs, I brought her back down to the recommended amount and have stuck to it since. She has nearly doubled in size in less than 2 months, 30 lbs to now 54 lbs, and I have been able to keep her at a good body ratio the whole time! Ultimately, she is an absolute beast at 7 months old and is stronger than any GSD I've had (Even as a pup). She eats this food like she is dying, so I rated the flavor as 5 stars. It is average price for large breed puppy food, but I buy the largest bag they sell and it lasts about a month. I'd rate the value as a 3.5 ish and I will keep buying it until she graduates to adult food based on the amazing results I've see in her so far. Side Note - 1st Vet Appt was a few days ago and our vet she is in impeccable physical condition - Muscle mass, Fur, Teeth etc, so to keep up what we're doing! I do add olive oil to her food each night (Just a few tablespoons) and this helps with the skin and coat too!

I was having a hard time finding a good puppy food specifically for a larger breed, so I was really happy to find this one. My puppy has done great with the Diamond Naturals Large Breed Puppy formula, and the lamb and rice recipe has worked out really well for us. I also love the convenience of having a 40-lb bag delivered right to my door. Great option for large-breed puppies!

As a pet owner with a beagle who’s allergic to chicken, finding a suitable dog food was a challenge. Most brands sneak chicken into their formulas, but Diamond Lamb and Rice has been a game-changer. This chicken-free recipe is gentle on my beagle’s sensitive stomach, and he devours it with his usual gusto. Unlike other foods that trigger intense itching and hot ears due to his allergy, this one keeps those symptoms at bay. His coat remains glossy, and at his senior age, he’s still happy and energetic. I’ve been buying Diamond Lamb and Rice for a while now, and its consistent quality keeps my pup thriving. For anyone struggling to find a chicken-free dog food that’s both palatable and effective, I highly recommend this product. It’s a reliable, allergy-friendly choice that delivers.
