Pet nutrition backed by science and research The PURINA ONE range provides everything you need to keep your pet healthy and happy, no matter what. Our natural dog and cat food formulas use only the best ingredients with added vitamins, minerals, and nutrients - so you know your pet is getting the best formula for them.

Purina One is a grain-inclusive dry dog food using at least a moderate amount of named meat meal and named by-product meal as its dominant source of animal protein, thus earning the product line 3.5 stars. Recommended.

Purina ONE still offers the same great SmartBlend of nutrition in our teal and red bags of pet food. We simply removed the term “SmartBlend” from the front of the bag when we redesigned our packages.

Purina ONE +Plus Vibrant Maturity Adult 7+ Formula combines nature and research for results you can see in your senior dog. That includes a SmartBlend® of high-quality ingredients, plus MCT-rich vegetable oil, for a formula that supports your senior dog's mental sharpness & healthy energy.

Purina ONE is a quality choice for dogs who need help managing their weight. However, if pet owners want to add probiotics and more natural ingredients to their dog's diet, a slightly pricier alternative is available from Purina, Purina Pro Plan Weight Management.

The Dog Food Advisor finds Purina Pro Plan to be an above-average kibble. Each grain-inclusive recipe uses a moderate amount of named meat and by-product meals as its primary source of animal protein, thus earning the brand 4 stars. Pro Plan Bright Mind gets 4.5 stars. Highly recommended.

If signs such as weight loss, excessive drooling, vomiting, loss of appetite or increased thirst or urination have occurred in their dog while eating this diet, pet owners should contact their veterinarian. No other Purina pet care products are affected.

They look the same and have the same ingredients so what exactly is the difference other than the cost? They don't have the same exact ingredients. The tender selects has corn gluten meal for one, which is an ingredient I refuse to feed my cats. The true instinct does not have any corn products.
