Purina One Dog Food: An In-Depth Review


You love your dog and want to provide them with the very best, but the prices on some high-end dog food available today are just astronomical. Can you feed your dog well without breaking the bank?

Purina One dog food has been serving dogs for a long time. Are they still a great choice for quality and inexpensive food? In this in-depth review of Purina One dog food, I look deeper into this brand to determine whether it provides a high-quality yet affordable choice for you and your pup.

Things to consider before buying an affordable quality dog food

Just because you want to feed your dog well doesn’t mean that you can afford the crazy prices on top-shelf dog food.  Luckily, you can provide your dog with a nutritious and well-balanced diet without paying as much as you do for your own groceries. Here are some things to look for in the ideal dog food. 

Real meat as the first ingredient

Whatever diet you choose, you want food that offers plenty of protein from meat. Ideally, you will be able to choose from different protein sources such as chicken, turkey, beef, and lamb. You also want to see meat as secondary ingredients, especially meat meal. Meat meal packs more protein per ounce than muscle meat.

Formulas for different needs

Once you find a dog food brand that works well for your dog and that you can afford, you don’t want to have to switch to another brand if your dog develops a special need. For instance, if your dog needs to go on a weight-loss or a limited-ingredient diet, you’ll probably want to stick with the same brand they have grown accustomed to. 

For this reason, you should choose a dog food brand that offers a range of formulas to meet your dog’s needs throughout life, from puppyhood into old age. It’s great to find a brand that also offers food at different prices depending on the quality of the ingredients.

Some dogs do just fine on a diet high in corn, wheat, and soy, while other dogs need higher quality grains or a grain-free diet that may cost more to make. Choose a company that charges accordingly for the ingredients in the dog food. 

Quality ingredients

Every ingredient in your dog’s food should have a purpose and work towards the overall nourishment of your dog. Even ingredients that some people prefer not to have in their dog food (such as corn, wheat, or soy) have nutritional benefits for your dog. Additionally, most dogs digest them just fine. At the very least, you should understand the purposes of the primary ingredients. Avoid products with unidentifiable “mystery” ingredients.  

Purina One Dog Food: An In-Depth Review

Purina One is an affordable, high-quality food that uses meat as the first ingredient and offers a wide range of different recipes to meet the needs of every dog. You can choose from formulas for puppies of all sizes, recipes for dogs with sensitive stomachs, or limited-ingredient diets for dogs. There are also high-protein recipes and a recipe for older dogs.

Foods are not only formulated to meet AAFCO standards but are also tested with animal feeding tests using AAFCO procedures. They have been found to provide complete and balanced nutrition for your dog.


  • Affordable food with formulas that will serve your dog throughout their life
  • Offers varieties with limited ingredients, grain-free, high-protein, and other specialized diets
  • Offers food for both large and small breed dogs from puppyhood throughout life
  • Diets are not just formulated to meet standards but actively tested to be sure they are balanced for your dog’s nutritional needs


  • Many recipes include products from wheat, corn, and soy, which people often seek to avoid in their pet foods
  • Some dogs experience digestive upset or gas, especially with the high-protein and grain-free diets
  • Bags do not come with velcro or zipper seal, so you need to find a way to close it to keep the product fresh 

 Specialized products

You can tell that Purina One cares about the needs of every dog by their line of specialized products. Even if your dog doesn’t need a special diet now, you don’t want to have to switch dog food brands if your dog suddenly needs a special formula or as your dog moves into old age. 

The standard diet comes in both regular kibble size and small bites for little dogs. Purina One offers a range of specialized products to set you up for success in feeding your dog exactly what they need to be healthy.

Wet dog food is offered to serve the needs of older dogs and adult dogs of small and large breed sizes. You’ll find options for dogs that need weight management and dogs that need to avoid corn, wheat, or soy. Grain-free options are also available.

Digestive Health

This formula is specifically designed to make digestion easier for your dog; it offers probiotics so your dog gets the most out of every bite they eat. Sometimes, even if you are giving your dog a very high-quality diet with food they should be able to digest, they don’t get the most out of it. Added probiotics make it easier for your dog to digest the nutrients they need.

Chicken is the first ingredient, providing a highly digestible form of protein. It is followed by brewers rice, which is also easy for your dog to digest. Crude protein of 25% gives your dog what they need to build powerful muscles while a fat level of only 16% ensures that your dog won’t gain weight on this diet.

Healthy weight

You know how hard it is for you to keep the pounds off, and it can be a struggle for your dog as well. It’s very frustrating to give your dog the appropriate amount of food only to have them begging you for more minutes or hours later. You need a diet that will fill your dog up so they don’t keep begging for more. You also want a diet that will keep your dog from gaining weight, which can prove dangerous for their joints and back.

This dog food uses turkey as the first ingredient to give your dog a strong dose of protein without the calories. Rice and soy naturally promote healthy weight and fill your dog up. An antioxidant blend of vitamins A and E supports your dog’s immune system. You can feel good about giving your dog a diet with a crude protein level of 27% and only 8% to 12% crude fat. 

Puppy formulas

You want to start your puppy off right. This healthy puppy food uses chicken as the first ingredient and includes other ingredients that offer essential nutrients, including rice and oatmeal. Puppies need more protein, but they can’t have too much or they may grow too quickly. 

This diet provides just the right balance of protein and fat to give your dog what they need to grow. It is also supplemented with DHA, which is a nutrient found in mother’s milk that helps your pup develop a healthy brain and eyes. 

A blend of vitamins A and E, along with the minerals selenium and zinc, offer a complete diet rich in antioxidants to keep up your puppy’s immune system. Your puppy gets plenty of protein in this diet with 28% and lots of healthy fat, too, at 17%. 

Limited ingredient diet

If your dog is suffering from digestive upset due to allergies, the only way to find out what is bothering them is by ruling out potential allergens. This limited ingredient diet has only nine completely natural ingredients that may be allergens, along with other essential nutrients that are unlikely to create an allergic reaction. 

The only animal proteins are from chicken and beef, with chicken as the first ingredient and beef fat that is naturally preserved with vitamin E. Other ingredients include rice, barley, canola meal, and oatmeal, all of which are unlikely to prompt an allergic response to grains like corn and wheat can do. Crude protein of 24% and fat of 14% provide a good balance to maintain your dog while keeping fat a little bit low to allow easier digestion. 

Sensitive systems

If your dog struggles to digest their food, and especially if they experience dry or flaky skin, this sensitive systems diet may be perfect for them. Salmon, the first ingredient, provides an excellent source of glucosamine for joint health and omega-6 fatty acids to give your dog a beautiful coat and healthy skin. 

Rice flour, pearled barley, and oatmeal are grains that are easier to digest than wheat; your dog will benefit not only from the skin-improving qualities of oatmeal but also find relief from digestive upset. This food is designed to maintain your dog, with a crude protein at 26% and fat of 16%. 


Most dogs who suffer from allergies are allergic to protein such as chicken and beef, dairy products, and/or eggs. If they suffer from grain allergies, most dogs have problems with corn, wheat, and soy. Some dogs, however, seem to have difficulty digesting any grains.

If your veterinarian has recommended a grain-free diet for your dog, this option from Purina One may be a good choice. In the beef recipe, beef is the first ingredient, followed by chicken meal. In the chicken recipe, chicken is followed directly by chicken meal. 

In place of grain, they use canola meal, lentil flour, Cassava root flour, and pea starch. Not surprisingly, this grain-free recipe is particularly high in protein. 30% protein is enough to give muscle building power to even very energetic dogs. A crude fat of 17% means that your dog won’t gain weight on this diet. 

High protein

If you want even more protein than the grain-free diet has to offer and you want your dog to have the continuous energy offered by carbohydrates in grain, this high-protein diet may be perfect for you. The first ingredients are beef or turkey, depending on the formula. Corn gluten meal, chicken meal, and soybean meal provide a powerful dose of protein so your dog can forge through each day. 

Salmon offers an added boost of glucosamine and Omega 6. A crude protein of 32% with only 17% fat means that your dog will gain muscle, not fat. The turkey and venison formula provides slightly less crude protein at 30%. 

Vibrant maturity

When your dog gets older, Vibrant Maturity may be the recipe for them. This formula is made specifically for dogs that are seven years or older. Chicken is the first ingredient, providing a highly digestible form of protein. Added botanical oils offer a great fuel source for your older dog’s brain, enabling them to think like they did when they were young. Grains like soybean meal and oatmeal provide lasting carbohydrates. 

What people say about Purina One

In general, people are very happy with this affordable food that meets their dogs’ special needs. People who need a limited-ingredient food for their dogs were thrilled to find that the limited ingredient options offered by Purina are affordable enough that they can feed them throughout a large dog’s entire life. 

Alternatives to Purina One

NUTRO MAX Adult Dry Dog Food

You’ll pay a little bit more for Nutro Max than you would for Purina One, but you may prefer the ingredients offered in this recipe over those provided by Purina One. The first ingredient in this food is chicken meal, which offers more protein from meat than the chicken muscle protein in Purina One.

Grains include whole-grain sorghum, Brewers rice, and oatmeal, all very easy for your dog to digest and packed with vitamins and minerals.

  • The chicken meal in Nutro packs more protein than chicken muscle meat in Purina One
  • Slightly more expensive than Purina One
  • Offers very high-quality grains at a reasonable price

Whole Earth Farms Grain Free

If you are willing to spend more for the best dog food that offers predictable ingredients, this Whole Earth formula may be what you’re looking for. This is a grain-free diet that contains no poultry; if your dog has allergies to grain or chicken, this might be a great choice for you.

Pork meal is the first ingredient and offers a great source of concentrated protein. Other great proteins are included as well, including muscle meat from pork, beef, and lamb.

  • More expensive than Purina One
  • Contains probiotics in the standard diet to make it easier for your dog to digest
  • A poultry-free option gives plenty of protein from various animal meat while avoiding potential allergens in chicken and turkey

Pedigree Adult Dry Dog Food

If you don’t want to spend any more than you have to for quality food for your dog, you may want to consider this option by Pedigree. This is one of the most affordable foods that you’ll find on the market.

Corn is the first ingredient, followed by meat and bone meal. You do want meat as a first ingredient if possible, but if your dog has no trouble digesting corn, this affordable diet is nutritionally balanced for your dog’s needs. It should prove sufficient to keep them healthy and happy throughout their life without costing you more than you can afford to spend.

  • Much more affordable than Purina One
  • Corn is the first ingredient
  • Meat and bone meal provides a great source of protein and calcium; however, you can’t eliminate any animal protein since you don’t know where the meat comes from

My fiance, Justin, and I live with our two little dogs, Sofie and Lisa, and three chickens in Gainesville, Florida. Justin and I are homebodies who occasionally enjoy a good adventure. I love living in Gainesville, and I love Florida. I can’t imagine anywhere more beautiful or strange than this hot, marshy place where people are guaranteed to be nothing other than themselves. Justin is always reminding me to relax. Relaxing doesn’t come naturally to me. I’m always busy. Making art or editing photos, digging in the yard or trying to grow some new moss or plant. There never seems to be enough time to do everything that I want to do. Life is so, so full and I want to plunge into every second of it.
