Dry Dog Food

Product Overview

In our Large Breed Adult Formula Dog Food, real chicken is our first ingredient, along with other key ingredients and nutrients including rice and glucosamine. Why? Because feeding a large breed dog is a balancing act.

An ideal body condition helps minimize stress on bones and joints. And the right balance of vitamins, minerals and other nutrients helps them live large, healthy and strong. It's choosing ingredients that work better together than they ever could on their own that inspired us to call this dry dog food SmartBlend.

What's A Dual Defense Antioxidant Blend? One That Works Inside & Out.

It's probably not something your dog thinks about, but his SmartBlend is working around the clock. It starts with a dual defense antioxidant blend of Vitamins E & A along with minerals zinc and selenium in a 100% complete diet for your adult dog. Together, they make a healthy difference on the inside by supporting your dog's strong immune system and on the outside by supporting healthy skin and a radiant coat. 

We're inspired by the science in nature, discovering the power of smart ingredients that work together for your large breed dog's whole body health.

  • Real chicken as the first ingredient blended with other high-quality protein sources helps build strong muscles and a healthy heart
  • Omega-6 helps give your dog a radiant coat and healthy skin
  • Natural sources of glucosamine to help support healthy joints
  • Highly digestible so more nutrition goes to work inside your dog

Weight of Dog (lbs) Weight of Dog (kg) Amount to Feed (cups) Amount to Feed (grams)
51 - 75 23.1 - 34.0 3 1/4 - 4 1/4 299 - 391

The recommended feeding amounts indicated are based upon the average nutritional needs of an adult dog with a normal activity level (using a standard 250 mL/8 oz measuring cup, which contains approximately 92 g of Purina ONE). Factors, such as a dog's metabolism, breed size, activity level, age and whether the dog is spayed or neutered, will affect the amount of Purina One needed to maintain an ideal body condition. The pet experts at Purina have provided the feeding amounts indicated as a starting point. If you find that your dog is losing weight or becomes slightly overweight when fed these amounts, please adjust accordingly. To help your dog maintain an ideal body condition, monitor your dog's weight on a regular basis, making sure that his ribs are easily felt and his waist is visible when viewed from above. Maintaining an ideal body condition can impact your dog's lifelong health.


Purina ONE SmartBlend Large Breed Adult Formula is specifically formulated for maintenance of adult dogs. If you have a puppy, or a pregnant or nursing dog, feed Purina ONE SmartBlend Healthy Puppy Formula.


Purina ONE may be fed dry or mixed with water. If mixed, we suggest one part liquid to four parts Purina ONE.


Although you'll be anxious to see the difference Purina ONE can make in your dog, please allow 7 - 10 days to ease the transition from his current food. Each day, simply feed a little less of the previous food and a little more Purina ONE until you're feeding Purina ONE exclusively. This gradual transition will help avoid dietary upsets.


Purina ONE provides 100% complete and balanced nutrition for maintenance of adult dogs. There is no need to add vitamins, minerals or other supplements, unless specifically directed by a veterinarian.


Be sure to provide fresh water in a clean container for your dog daily. Proper diet, exercise and veterinary care are the best ways to keep your dog healthy. If your dog hasn't had a check-up in the past year, please make and appointment today.

Purina One Smartblend

I have two large dogs Leroy (mixed Lab breed) and Charlie ( purebred Rough Collie). Both of absolutely love the dog food. Leroy before on other brands he would leave it until he was real hungry but not Purina One, he loves it his health the best it has been and his coat is soft and shiny :-). Charlie has only ever had Purina dog food when he was with the breeders he started out with Purina Pro but when I got him I switched him to Purina one puppy. He also is very healthy and a beautiful coat.

Meat first

We purchased this brand often for our pitbull x, meat as the first ingredient is extremely important to us, we spent a long time searching for that one product that we knew was not going to be just loaded with fillers. Our girl can be very particular , she likes to have her dog food changed often, we've never had her have stomach issues from switching between the Purina one flavours. Overall Very satisfied with this product, Price point is satisfying, will buy again and would refer to friends

My dogs love this blend

I have 2 very picky dogs and one has severe allergies, the Pyrenees. I have tried so many super expensive, all natural/organic and vet recommended foods and no matter what they said was best she just wouldn't eat it. A friend suggested the lamb smart blend and it was a hit from the first bowl, and for some reason she's not allergic to the ingredients. Her hot spots have decreased and my older lab loves it too! I'll be sticking with this food as long as I can, no more full bowls going in the garbage! Thanks!!

Since than we have had a compliment from our vet he has been our fur babies vet for over 20 years now and he told us that our fur baby has been looking more healthy than before as he was examining her for hey yearly check up we told him we had recently changer her food and we told him that she has been having more energy also her fur has been so shiny we love that it has No added fillers or artificial flavors that was the reason we had changed her because of what was in her old food we have been very happy with our babies results and compliments thank you for making a awesome food for our baby :) i HAVE INCLUDED A PICTURE OF HOW HEALTHY SHE LOOKS <3

Puppy loves it

Adopted a greyhound last year and had constant problems with gas and loose poops. Additionally, my dog did not appear to really like the food. She picked at it and would sometimes not eat for a day or two. A friend who has three older greyhounds suggested Alpo. I couldn't find Alpo but got Purina One and now she has almost no gas and great poops (you would have to be a greyhound mom to understand what a big deal this is! LOL) Now she loves eating her breakfast and supper and eats it all up at once. Never misses a meal.
