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./250mL measuring cup which contains approximately 96 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 may be fed dry or mixed with water. If mixed, we suggest one part liquid to four parts 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.

My 8 yr. old Collie Rough is a very pickey eater, but he loves this product!

I have brought home several different brands of dog food, including other types of Purina, only to have my Collie snub them and refuse to eat at all. However, Vibrant Maturity seems to be what he has been waiting for and the humans don't have to share their dinner!

Simply The Best!

I have fed many expensive and inexpensive foods to my dogs over the years. I never noticed a visible difference in any of them...Until NOW!

I have two senior black labs, 11 and 12 yrs. Old.

I have seen a HUGE change in their mental alertness, activity level, and overall zeal and zest for life! They are bouncing around like pups, and have a brightness in their eyes again! They are so zestful, I threaten to take away the new food! LOL!

I can't say enough about what a great difference I've seen in my two old dogs! My 12 yrs suffers from arthritis and hip problems, she didn't want to do much..Now, she is out walking with me, even running sometimes!!!

I feel strongly, if you have a senior dog, Purina One Vibrant Mature is the food to buy! I highly recommend this particular product!!!!!

I can't believe what a difference this dog food has made!!!

Please, please keep making it Purina!

No more meds

My Border Collie has arthritis in his hips and has been on Rimadyl to help him out. He is 11 1/2 years old.
My spaniel mix is 10 and she is a picky eater. They were eating Purina dog chow. So I switched to Purina One Active Maturity.
My Border Collie is off his Rimadyl and is playing like a puppy. I no longer have to mix wet food with the dry to get my spaniel mix to eat. She inhales it.
Thank you Purina for this food. Our pups are happy.

Answer to our Prayers

Our 14 year old Jack Russel Tarrier (Napoleon) has had a rough go as of late. His thyroid has begun to act up and he went from a healthy 16 pounds to 26 pounds. Well we started looking for a replacement for his other name brand food and came across Purena's Vibrant Mateurity formula. We are proud to say that our Napoleon is gonna be around with us for a few more years. Not only does he love the flavor, he has lost 8 pounds and is acting like his old self again. Also he poops alot less cause there are less fillers and his body uses it all up for nutrition...Switched our other pets to Purena One and great results as well (:

Great changes!

We have an English Setter/Brittany cross, Lucy, who is 9 1/2 yrs. old. She was put on this planet to be a love & forever stalk squirrels, which she NEVER outsmarts!
Last summer we switched her from Purina One Senior because we thought she was becoming allergic to the food. She began itching & everyone told me to go GRAIN-FREE!!
So....we switched her to a HIGH END grain free froduct. She's gained more weight than usual this winter, has clean teeth, but horrible breath and VERY large stool volume!!! What's up with that!!
Lucy's gradually going back to Purina One Senior Vibrant Maturity & looks great! More energy, the breath is changing along with the stool volume

Keeps my Senior from inhaling his food!

I got Chevy (Pitbull/Dachshund) when he was 7 years old from the local shelter. He was very underweight, and even though he is a healthy weight now, and also 14, he still feels the need to inhale his food even after being well taken care of for 7 years. Every food he gets he has always inhaled and then consequently he was suffering from vomiting/loose stools. Every senior dog food I could find had similar sized kibble, which must have been the perfect size for him to inhale, until Purina One! The Vibrant Maturity 7+ food has very small kibbles and meaty bits, therefore my dog has learned he needs to chew! I also think the chewy meaty bits make him want to slow down and savor the flavor! This food also includes a generous joint health blend, and I have been able to take him off his joint supplements with no adverse effects! Thank you Purina One for offering this affordable food that saves my stubbornly hungry senior dog from his tummy woes!
