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.

Feeding Guidelines

ADULT DOG FEEDING INSTRUCTIONS
The recommended feeding amounts indicated are based upon the average nutritional needs of an adult dog with a normal activity level (using a standard 8 oz/250 ml 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 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.

IT'S NOT FOR ALL DOGS
Purina ONE SMARTBlend Large Breed Adult Formula is specifically formulated for adult dogs. If you have a puppy, or a pregnant or nursing dog, feed Purina ONE SMARTBlend Healthy Puppy Formula.

MAY BE SERVED DRY OR MOISTENED
Purina ONE may be fed dry or mixed with water. If mixed, we suggest one part liquid to four parts Purina ONE.

MAKING THE SWITCH TO 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.

NO SUPPLEMENTS NECESSARY
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.

FRESH WATER, PROPER DIET & VETERINARY CARE
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 an appointment today.

excellent stamina without the added pounds!

My 10 year old Black Lab has been raised on Purina One. She has always had an excellent coat, and abundant energy. She's not as fussy as some dogs, she liked all the flavors, chicken, lamb, even the Sensitive skin kind, and certainly the latest venison, but I'm the one who inspects the ingredient list, and through the years the LARGE BREED ADULT has kept her trim and proper. Thank you Purina One, for a product her and I can trust with out hesitation.

Truly Amazing

Truly a Amazing Product. My wife and I rescued a 13 month old German Shepard. When you tried to pet him it was like petting a wire brush. His eyes where dull looking and lacked energy. We started Him and the Large Adult Breed. and he truly loved it. Or other dog is a German Shepard Blue Heeler mix so we Started him on the dame product. There Eyes are Bright and Vibarent. There Coats are AMAZING Soft and a true enjoyment to pet. And there Energy Level is out of this world. Glad we Made the switch.

Great food! Great price!!

We just got our first dog and a friend recommended Purina One. After trying an expensive grain-free food that our dog did not like we switched. Now our 7 month old girl is more than happy to eat her dog food! And Purina is much more affordable!

Best for large breed!

I have two English Mastiffs and this is the only food they eat. When I got them as puppies, a year apart and from two different states, they both were eating another brand and quickly decided they no longer liked that brand. I switched them first to Purina One Large breed puppy, then as they got older to large breed adult and have never looked back. they are now 3 years and 150lbs, and 1 year 120 lbs and thriving! I love my big boys and they love your dog food!

best large breed I have ever used

We never imagined when we got our mastiff male the extra needed vitamins and glucosamine needed to keep them healthy! Of course our vet sent us home with food that was near $60 a bag and he wouldn't touch it! So we shopped around compared labels and found this!!! Purina Smart blend large breed! It actually exceeded the vet brand and my dogs love the meaty chunks. We purchased a female a yr ago and after sending our breeder tons of pics of how big and healthy she is the woman ask me ok so I have to know what food you are using because Rowsey is double the size w a much prettier coat than either of her parents. I told her and she was in awe bc she too had been using the vet recommended food and spending a fortune! Upon her switching her older male within days has relief in his hips and was able to get around better! WILL USE NOTHING ELSE. If u love your Dane, Mastiff or Rott I would totally recommend!!!

Wonderful!

I switched my two German Shepherds from Iams Large Breed Puppy to Purina One Large Breed Adult at 1 year because they were both starting to have problem with the Iams. I could tell a difference even in the middle of switching and since they have been completely switched no more dietary issues. Their coats are beautiful and a shiny black. They are both very active and both love this food. My female eats it much better than she did the Iams. From now on these two and any future dogs will be on Purina One.
