Purina Pro Plan Veterinary Diets OM Overweight Management Formula Dry Dog Food is rated 4.8 out of 5 by 49.
Rated 5 out of 5 by from Best Food we've discoved yet!! The Purina Pro Plan OM (Overweight Management) was recommended by our vet to reduce and maintain our newly adopted English Bulldog's weight. It worked extremely well. He receives two cups of the food three times a day to match his previous intake. It fills him up and kept him trim and healthy. We switched our French Bulldog to this food from the Purina Pro Plan EN (EN GastroEnteric) formula. The Frenchie had skin allergies to various table scraps and typical dog food. Although the EN cured the skin irritation we gambled on Pro Plan OM for both dogs believing that the higher Qual ingredients of the Pro Plan (either formula) would be suitable for the Frenchie. We were correct and now both dogs benefit from that full feeling along with keeping both our brachycephalic fur kids as healthy as can be.

Rated 5 out of 5 by from Product helped my dog lose 9 lbs. and maintain her weight. Makes for a healthier dog! This is a great product to help your dog lose and maintain its weight. Its a bit pricy; however it does work. If your willing to spend the money; its worth a try.

Rated 5 out of 5 by from Convenience Plus! I love the convenience of ordering from Chewy.com. No longer do I have to take time out of my busy schedule to run to the vet's office only to pick up a bag of food for my dog. It is delivered right to my door. I compared prices between Chewy.com and other sites, as well as with my vet, and the Chewy.com prices are the best that I have found. I can get the exact same food that my vet has recommended for my dog. I also like the added feature that the Chewy.com site offers by having an automatic ordering feature so that I don't need to worry about forgetting to order until my dog's food runs out.

Rated 5 out of 5 by from Purina OM is a great product. I have used Purina OM for a year now, and switched from Royal canine OM. The dogs do not eat as much which makes it actually more budget friendly, and are not banging their bowls between feelings.This product is also great if they have allergies. And their skin and coat well are maintained.

Rated 5 out of 5 by from This is the one... My golden has had numerous issues with her pancreas and needs, basically, fat free food, which is not an easy task! However, this food fits the bill. She has been on it for almost two years and no more issues... (knock on wood)... and the best part is, she loves it!!!!
