Start puppies on moistened Purina ONE as early as they will nibble at solid foods, generally 3-4 weeks of age. Allow your puppy to eat at will until fully weaned (6-8 weeks). After weaning, feed pups (to six months of age) all of the moistened or dry Purina ONE they will consume at intervals throughout the day. If water is added, use no more than one part warm (not hot) liquid to four parts Purina ONE, changing frequently to ensure freshness. If fed dry, this formula may be kept before pups at all times. For best results, develop a regular feeding schedule, such as three small meals a day for younger puppies. Gradually reduce the one feeding in the morning to one in the evening as your puppy ages. The routine should not vary.
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.

Tailored Nutrition for Every Pet
Purina One Smartblend formulas are made with high-quality ingredients, delivering the taste dogs love and the nutrients they need. These dry and wet food recipes are inspired by nature and advanced by science to give your dog a complete and balanced meal with real meat, fish or poultry as the number one ingredient. With selections for dogs of every age and breed, plus formulas that target weight and sensitivities, you'll find the perfect Purina One for your pup.


Premium Smartblend for Adult Dogs
Adult dogs will enjoy Premium Smartblend real lamb or chicken formulas with the exciting texture combination of tender, meaty morsels alongside a classic crunchy kibble. Nutrient-dense True Instinct has even more soft morsels of meat with two animal proteins. If you want to go grain-free and all-crunch, Smartblend True Instinct with beef and sweet potato could be your pup's new favorite.
Puppy and Senior Health
Purina provides the ideal diet to keep your pet healthy throughout his life with life-stage specific dry foods. Smartblend Healthy Puppy gives growing puppies high levels of essential nutrients, including protein and DHA for vision and brain development. Once your pooch reaches age 7, the Vibrant Maturity 7+ Senior formula helps nourish his mind with enhanced botanical oils that provide energy for the brain.


For Dogs Big and Small
Small breeds can benefit from Small Bites Beef and Rice, a kibble that's easy to eat with bite-size pieces. And for the big dogs, Smartblend Large Breed formulas help maintain an ideal body condition that minimizes the stress placed on bones and joints. Puppies get just the right amount of protein, vitamins, minerals and glucosamine to help them grow at the right pace, and Large Breed Adult continues the delicate balancing act of key nutrients for strong bones and muscles.
Targeted Nutrition
By researching different ingredient combinations, Purina One created Targeted Nutrition formulas that are optimized for your pet's lifestyle. With 25% less fat and 15% fewer calories than the Lamb and Rice Adult formula, Smartblend Healthy Weight promotes a naturally healthy weight. Sensitive Systems is a diet designed to nurture sensitive skin and stomachs with rice and oatmeal that are easy to digest, plus omega-6 and vitamin E for a radiant coat.


Delicious Wet Food Entrées
Serve it as a complete meal or topper—either way, Purina One wet food satisfies cravings with tasty real chicken, duck, turkey, venison, lamb and beef entrées. Choose from Classic Ground or Tender Cuts in Gravy—both have twice the recommended antioxidant levels with zinc, selenium, and vitamins A and E. For a nutrient-dense meal with two different protein sources, True Instinct's a great choice, and it comes in grain-free formulas for sensitive pets.

For dry puppy chow, it's not bad!
By Luna on Feb 19, 2021
Since my human likes my poops to be drier, this stuff delivers. I like to get a mouth-full of it and take it over to where my human is working at his computer and chew it up there. Then I go back for another mouth full. I like the way it tastes and I eat a heaping coffee cup full of it every day. When my human mixes it with some canned Purina One, it makes me happier than I have the capacity to contain. When he cracks an egg on top of it, I tend to lose all measures of decorum and eat so much of it that I need to go lay down for a while before I can chew on his house shoes. When he reaches into the bag to scoop it out, it makes me love him so much I can't stand it. This guy is a real keeper. Since my human likes my poops to be drier, this stuff delivers.

Can't get enough!
By Jenna on Mar 2, 2021
I read through reviews for hours looking for the best food for our pup, Ruthie. I went with the Purina ONE Smartblend Large Breed Puppy food based on reviews. She is obsessed with her new food...it's almost like the prior food she was on must have tasted like cardboard. She is jazzed for breakfast and dinner now! Also, her poop has never been drier! Amazing since it was so frequently soft-serve with her old food. Great puppy food!

My bby didnt like it.
By OhNooo on Feb 14, 2021
I went with this food because I once dog sat my friends dog (before I got mine who her dog was the father of) & her dog loved it he was also a very beautiful dog. I could see the difference in his build also. But my fur baby didnt like it at all. We tried mixing it with soft food & sometimes even rice but she would pick through it & eat the soft pieces. Sometimes she wouldn't eat it at all. I wouldnt say I dont recommend it because as I said my friends dog still eats this food & it works for him it just didnt sit right with mine. Its definitely worth a try if you have a big dog though.

Great Food!
By 2Brothers on Feb 12, 2021
Our two 5 month olds love this food! We mix it with another Purina Puppy Chow food for them and they eat every piece of food and clean up the floor from whatever got away from them. We did some research and found our boys should be getting a food to help them grow to their potential as they are large breeds and need as much protein with little carbs as possible. We stay away from grain-free for larger breeds cause of the health issues that can come into play for them. The two of them have so much energy, healthy skin/coats and growth in their nails (we have to get them trimmed every 2-3 weeks) from this food.

Tried and True
By DogLady on Feb 15, 2021
I consistently go back to this food for my big dogs. They have gleaming coats, firm easy to clean up poops, hold weight well, and just thrive their very best on this, even over more expensive foods. On a budget you really can't beat this brand, though I'd feed it for the results even if money was no object.

Puppy loves the food
By Jackie on Feb 24, 2021
Our new rescue puppy loves this food! We bought the wrong brand after some confusion with the shelter got us the wrong name of the food she was on while there- but she loves it so much she will even accept it as training treats.

wasn’t good for our GD
By AA1022 on Jan 28, 2021
We bought this cause we always used purina. Our GD had lose stool the whole time he was on it. We switched to another large breed food. That didn’t have chicken and it has helped. Also I noticed the more bags I received the smaller the chunks of chicken were. Have always liked purina but this food has changed our mind.

He love, love, loves his food !!!
By Gretzky on Dec 31, 2020
So far our 15 week old Hound/Pittie mix loves his food...transitioned great from the food he was fed from the rescue to this and the Chewy rep that helped me with making that choice along with other purchases was absolutely fantastic. Love Chewy’s customer service. Will definitely be using the adult version when he is ready.
