Pets can be sensitive to sudden changes in their diets. For this reason, it is extremely important to follow a gradual transition plan to best support your pet's health and product effectiveness. It is recommended to follow at least a 7-day transition plan before exclusively feeding your pet a new food. Start by mixing 75% of your pet's current diet with 25% of the new diet on Day 1 and Day 2. On Day 3 and Day 4, mix 50% of the current diet with 50% of the new diet. On Day 5 and Day 6, mix 25% of the current diet with 75% of the new diet. On Day 7, you can feed your pet the new food exclusively. Ask your Veterinarian about the best way to transition your pet to a new food.

Days 1-2 | 75% | 25% |
Days 3-4 | 50% | 50% |
Days 5-6 | 25% | 75% |

Delicious kibbles
By Plan on Feb 23, 2021
Had to switch to a reduced calorie and fat diet for my pup who needs to lose 20#. The Purina Select Blend exceeded my expectations as I thought she would not like it but instead, she loves it! Hopefully this food will do the job and she will shed the excess pounds. I also give my pups Purina Lean Pupperoni which they really like.....All of us who use CHEWY for their furr kids needs, prescription and non prescription items are so fortunate that this Wonderful company exists!!

My dog loves her new food!
By Shirl on Mar 1, 2021
Our chihuahua loves her new food. We have been using it for about two weeks now and she continues to eat it up. We are beginning to see she is losing weight slowly. That is good. She needs to lose about 3 1/2 lbs. and we are eager to see her more healthy.

Lost 8.5lbs in 4 months
By Angel on Mar 3, 2021
Angel gained at least 20 lbs because of meds and an illness .. she was on the Purina Pro Plan OM and lost 8,5 lbs in 4 months. I’m told a dog losing 1lb is like 10 lbs to humans

overpadded dog
By Natali on Dec 27, 2020
My boy only 2 years old, but he gained 7 lb in only a few month. I decided to try the Purina OM since I trust the brand for a long time. I just started, not even a month, waiting for the effect. For now, my dog is doing well on that food, his energy level is the same (he is an English Springer Spaniel), no allergy, the stool is fine, overall positive feedback

Fantastic diet food
By BK12 on Jan 18, 2021
I was so pleased to see my picky eater dog likes this diet food and ate it the first time. It was very similar to the Purina Shredded chicken regular food she had been on.

Works Great!!!
By Sharbear on Nov 12, 2020
Chewy did an awesome job getting my order to me...appreciate the service. The Purina Om really does work for overweight dogs. I had my dog on it for a while and she lost twelve and a half pounds...so I thought I could go back to regular food. She started gaining so I am a big believer of this food and will not change again. Thank you Purina!!!

Helped my dog lose weight
By Allison on Nov 17, 2020
Although, it helped my dog lose weight I felt that both of my dogs were losing key nutrients with this food. After hours of research on dog foods, I was very concerned to find out what I had been feeding my dog. I will always use chewy, however, I am not sure I will use a Purina Pro Plan diet ever again.
