Heavy bag

The food is wonderful but as I am in my eighties, a 32 lb bag is much too heavy and I would rather order two of the , I believe, 18 lb bags and keep trying to call and talk to someone. All the operators have bbeen really nice but except for once I keep getting the 32 lb bags. Is there anything I can do?

My dogs absolutely love this food and I have noticed after the past month in using it that they have lost a little bit of weight. They have more energy so it is definitely improving their quality of life. Thank you so much for this product!!

Not sure about the results yet.

My little Aussie has gained weight as I was told she might. The food my vet prescribed has yet to show any results, but she has not been on it long enough to tell most likely. That's why I have to give a neutral star. Shipping was fast and I liked that about it.

Wonderful food

After trying four different brands and my dog gaining instead of loosing, finally he has lost four lbs. in two weeks. Doesn't seem like a lot but this is a GREAT BRAND WHICH WORKS. I hope that it will continue so my dog will be with us for a long time. Before the vet said that if he doesn't loose weight his life will end much sooner. Besides the food being great Chewy always stands behind everything that they sell. Great Company

Get the right one!

My dog lost a significant amount of weight using this product. BUT, be careful when ordering. There is also one that looks exactly the same, but if you read the description carefully It also says Prime Choice. I ordered that twice by mistake and he gained weight giving him the same amount of food as on just the regular overweight management. But the overweight management does do the trick. Now that I know the difference I'll just be careful when ordering.

Pro plan OM

My dog will actually eat this after trying others. So far he's not lost but a pound (4weeks) but he has not gained. He gets prescribed 2 3/4 cup per day he's full he just don't want to be.

I can hardly believe that my very picky dogs actually love this prescription food, but they scarf down every last crumb! Now Im just waiting for the scale to reflect their new, healthier diet. Thank you, Purina, and Chewy!
