Large Breed Adult Formula Premium Dog Food

Rated 4.9 out of 5 by 36reviewers.
Rated 5 out of 5 by Great Product! Our 2 huge dogs (150 lb. Rottweiler and 125 lb. Great Pyrenees) have been eating Purina One Large Breed since they were puppies. They love the food. Every time we come home with a new bag, I have to open it so Chubbs the Rottweiler can shove his head in and sample it. Our dogs are healthy and not overweight. They are both certified therapy dogs and we believe their diet greatly contributes to their energy and happy attitude necessary to do their work. We are always complimented on their beautiful teeth and coats. Thank you for creating a product that gives us peace of mind. Caring for these dogs is a challenge and having a food we are confident to feed gives us one less thing to worry about. February 19, 2014
Rated 5 out of 5 by 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! June 22, 2014
Rated 5 out of 5 by Like a puppy For our 11 year old Newfie, we thought he was slowing down due to age, but with the change to Purina ONE Large Breed has turned from being a slug into a popcorn-ing puppy. He's now bouncing around the yard once again. June 12, 2014
Rated 5 out of 5 by 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. October 4, 2013
Rated 5 out of 5 by My Three Dogs Agree! I have three large-to-medium dogs from various rescue organizations: one ex-racing greyhound, one mixed Australian Shepherd-Golden, and one mixed Golden- Spaniel-Chow. They're all fanatical lovers of their meals, and the one trait they share is a definite preference for Purina One. Yes, I've tried other brands for variety and convenience, but now I stick to their favorite, Purina One. April 9, 2014
Rated 5 out of 5 by Helped my Dog!!! I have a 75 lb white boxer/pitbull mix with very sensitive skin. At the advice of my friends and coworkers, I had tried every "high dollar" food, to no avail. My poor baby's hair kept falling out in patches! After trying every food from "natural" to "organic grain-free", I did some research to figure out what all of these food have in common, sweet potato and potatoes. I went to Purina One, within 3 days my baby's hair started to grow back! I am more than satisfied! Purina One makes an excellent product! I love the cost compared to the "high end" foods, my dog loves the taste and the little meaty bits, and it's a quality product that has helped Miss Punkin enormously! Thank you Purina One for making such a great food! March 20, 2013
Rated 5 out of 5 by Great quality, great value Our family includes a Great Dane and an American Bulldog. The Dane is 4 years old and, since puppyhood, he has been a picky eater and it has been difficult at times to keep him at an ideal weight. I've been through some very expensive, all natural, foods only to have him reject them after a few months or have stool problems. Since switching to Purina One two years ago, he has had no problems keeping his weight on, maintaining a healthy appetite, or with loose stools. We began to see the same issues with our Bully as she grew out of puppyhood and switched her from the pricey food she was getting (because that's what she had been fed by her breeder) to Purina One. We found out later there was a recall on the expensive, "all natural" food she had been eating. From my experience, it is nearly impossible to find a dry dog food with the quality of Purina One (hello chicken as a primary ingredient!) at such an affordable price. June 29, 2014
Rated 5 out of 5 by Dogs love less gas I have two dogs a pit bull and a shepard lab mix. I have tried multiple dog foods blue buffalo, chicken soup for the soul etc...... Both my dogs had really dry skin and terrible gas. Since switching to purina my dogs have almost no gas and they have alot less dandruff. They also seem to really enjoy this food but they eat anything and everything. Will def. stay with this brand. January 9, 2015

Rated 4 out of 5 by real good quality food my dog enjoys My female cane corso really likes this food a lot. She has tons of energy and her coat looks amazing. I am staying with this food because I beleave its the best out there. Why switch? It works. No need to fix it. September 28, 2012
Rated 5 out of 5 by My Girls Love It! We have two English Hounds in our family. They are six year old sisters and have been with us since they were pups. One of them starting showing signs of gastrointestinal distress so we took her to the vet. He recommended that we try a different food brand that focused on a specific list of ingredients. After about two weeks on Purina One Large Breed Adult Formula, her issues were less apparent and after a month, she is back to her old self. Both dogs have thrived on this product. Their coats are shinier and their eyes are clearer. I haven't really noticed a change in their energy levels. They always have been constantly on the go. I would definitely recommend this product!

Rated 5 out of 5 by Quality food my pup enjoys lilly loves this food tryed all diff brands science diet she hated themost id say.. and lilly has never had "cheap" dog food September 28, 2012
Rated 5 out of 5 by No more hair balls My vet recommended Purina One. I was skeptical at first. I had been feeding my 2 yr old German Shepherd grain free Blue Buffalo. She was having problems with diarrhea, hot spots and shedding (more than the average for a shepherd). After 2 bags of food her shedding is completely gone. No more hot spots. No more diarrhea . I'm impressed! We'll be staying with Purina One!! September 16, 2014
Rated 5 out of 5 by wonderful meal We used Purina One puppy chow and adult food for large breed dogs. He loved the food and always has a good looking coat and plenty of energy! Thank you! January 6, 2013
Rated 3 out of 5 by Quality control possible issue We have had our Golden on this product )puppy/adult) for 2 1/2 years but have found the quality control and consistency to vary from bag to bag. I have written and sent samples twice to Purina at their request regarding all of the crumble and grit (that you might find at the bottom of a bag) throughout the bag. This has to be more than a shipping and handling issue, the product is coming out and bagged with this stuff. We are in the process of finding a new product as our dog isn't very enthusiastic about his feedings. April 10, 2014
Rated 4 out of 5 by Quality has deminished over years I have owned and breeded Labs for 10 years and have been loyal to Purina One. Over the past 6-8 months I have noticed the quality of the product has deteriorated. It is very crumby. At first I thought it might just be one shipment that got jostled around on the truck too much, but it doesn't seem to matter what store or what town (within 25 mile radius) that I buy it at, the bag still has a large amount of crumbs in it. I also buy puppy formula and have not had the same experience with that. July 29, 2013
Rated 5 out of 5 by My syberian huskies loves this food I have two syberian huskies . One of the dogs when you touched his back you could feel his bones even though he was eating hearty. I changed to Purina One large breed and now he looks like a Mack Truck. His weight is up to 60 pounds and he does not shed hair as bad. He is very happy. At 5:00pm he starts knock on the door and talking until he get his Purina One. August 2, 2013
Rated 4 out of 5 by Bigger bags This is a great product for the price. My only downside is, I cannot find it in a larger quantity. I own 3 German Shepherds, I would prefer to purchsse a 100lb bag as opposed to 3 to 4 bags at a time. August 12, 2013
Rated 5 out of 5 by Quality food my dog enjoys Our dog loves this food she was under weight so we put her on this and she gained so much weight she looks like she ate a cowor ssomething. If you need your dog to gain some weight then PURINAONE is for your dog November 9, 2014
Rated 5 out of 5 by Taste Great! I have always fed my pets Purina products. I had both my dogs on the Purina Dog Chow but one of them was barely eating it. She would nibble on it all day. One day, I asked my husband to pick up a bag of food on his way home from work and merely by accident, he purchased the Purina One Large Breed dog food. We have been buying it since. Both dogs now eat until it is gone. They absolutely love it! They seem to have more energy and have not gained a lot of weight. I do wish, however, that coupons for this product was made more readily available. October 11, 2013
Rated 5 out of 5 by He loves it! Since my baby boy had parvo when he was young, he was very picky about what he ate, because he thought it was the food that was making him sick. We went through just about every kind of food out there, and we tried this one as a last resort, because it has the soft chunks inside. He loves it, and has gotten back on track for his growth! As long as he loves it, I'll keep buying it! December 12, 2013
Rated 5 out of 5 by Purina One keeps my dogs healthy My 8-year old Boxer Annabelle has eaten Purina One all of her adult life. She had a litter of 9 puppies 5 years ago, and all of them were weaned onto Purina One for large breed puppies. Annabelle's puppies' new owners were all given Purina One large breed puppy formula, most of whom then graduated to the adult formula. My vet always tells me to keep feeding our Boxers whatever we're feeding them because they are very healthy and fit. August 7, 2013
Rated 5 out of 5 by A quality food that my dog enjoys My 10 yr old black lab had gotten where he wasn't eating much...until I switched to Purina One Large Breed Adult Formula. I no longer have to coax him to eat. He loves this food. December 4, 2013
Rated 5 out of 5 by my goldendoodle LOVES all of the different flavors! great choices, pieces are perfectly sized.. doesn't smell gross like a lot of dried dog foods... August 14, 2014
Rated 5 out of 5 by The best We have an english mastiff & a pit bull. It has taken 3 yrs. to find a food that both of our girls like & is what I'm looking for in a food for them. July 8, 2014
Rated 5 out of 5 by Great for them I have used Purina One for years. This is our second set of dogs and they all love it. 2 scoops in morning, and 2 at night. My German Short hairs have great coats and are silky smooth to the touch. Would never buy anything else other than another flavor of your brand.Thanks. October 4, 2013
Rated 5 out of 5 by Quality dog food My two st Bernard's love this!!They enjoy it and they look healthy !!I have tried changing brands in the past - but am sticking to buying this. June 12, 2014
Rated 5 out of 5 by Just good food, all around Recently the high dollar food we were feeding our Old English Bullies, had a recall. I picked up a bag of Purina One and we never switched back. The dogs coats seem healthier and they are more active then ever.At my Vet's recommendation I feed my dogs the large breed formula and they love it. Finishing all they can, with no issues. The switch was easy as my dogs like it better then the other. The hardest part is remembering to not overfeed :) November 30, 2013

    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.


    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.


    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.


    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 an appointment today.
