Wrong food for medium size dogs. food is too big

i have been buying Iam's dog food for many years and it is a very good dog food. In April I bough this and didn't notice that it is for large breed dogs, so I have dog food that my dog can't chew up. I have talked to Chewy and and say sorry they don't get the same food for Medium dogs and that is all they have. Chewy didn't let me know that this 15# bags was not the same as the other 15# bags I have been buying for a long time. not good!! So I have decided to go to another buyer and get the size dog food I need.

Ol Girl Likes This Flavor Better!

Our Aussie was eating the Weight Management IAMS, but she got finicky about it after a couple bags. It did help her lose a few pounds while she was on it, but she just stopped eating it. So we bought the IAMS Chicken Senior Dog Food and so far so good with a half of the bag gone, she isn't hesitating to eat this flavor. Came quickly after switching.

Mature Dog food

Was worried our dog would not like changing from regular food to the mature food. Dog likes it fine so there were no issues.

Fast shipping! Great food that did not upset my dog's stomach!

First time we used Chewy and we were very happy with the super quick arrival of the food and the discount coupon we used actually worked, so this was a great deal. We have food for quite a while, but I am sure we will be back. Thanks!

Healthyaging dog food

I have used this before,but with smaller pieces. My dog has had very loose bowel movements since I started this new food. I mixed it with her previous bag for a week,no help. I am mixing it with rice now for slight improvement. Did you change the formula?

Great product and price

Size of the food for my GSD is much better than prior experience with other brands . The dogs like it and the price per pound is also great.

Purple bag for Seniors

I adopted an 8 year old Lab and he was 100lbs. He was previously fed Pedigree but I switched him to Iams Senior Large Breed a few months ago and he really likes it. His previous food gave him gas and I think had too many calories for an older dog. I worry about weight related problems with his leg and hip joints so I’m glad he has lost a little weight without ever acting hungry.

Dog seems to like it

I've been trying to find a dog food for my picky puppy. This one seems to fit the bill. And it's part of the Iams family so you know it's good.

My dog really likes this food

We've been feeding Deebo Purina One for years. We bought Iams due to Purina being out of stock. Deebo scarfs it down like he hasn't eaten in days. We're going to continue with Iams.
