Happy old dog

When his box arrived, Slip was so happy. He kept circling the box and sniffing it until I got it open. He ate a bowl of kibbles right away. But I have to say his true joy was in getting that box of milk bones.

Unhappy dogs

I have 3 dogs. 2 of them will eat anything! 1 is picky. Because of the picky eater, we have had to change food up frequently. Started giving them this food a week and a half ago. They ate it in the last and were content. Currently. All 3 dogs avoid eating this unless i add something like chicken broth. Very disappointed.

Something seems off with these bags of food. Our Great Dane has not finished a meal since we opened either bag, even when we add chicken broth to entice him. Do you know if there was a recall or any issues with Ian’s recently?

Gassy and Sick

I don’t know what happened to this brand. We will never buy Iams again. The first bag was fine. But we noticed that after she started eating the second bag of food that she became terribly gassy, all the time. She could (and would) clear a room, it smelled that bad. Her coat got waxy and smelly. She is a very athletic dog, but this food added weight to her. Not to mention the messiest/smelliest “trips outside” issues. I switched her food back to her old food (back in stock) and immediately she was fine. No more farts & the extra weight around her ribs was off by the end of the weekend. 100% believe the food was the cause of all these issues. Hoping her coat returns to normal soon.

Great for my dog

1 year old Chesapeake bay retriever. Had to change from another food due to getting sick for whatever reason. She has been on Iams for months no with no issues. Great quality dog food.

Something changed with this food

our lab has been eating this food for the past 3 years and recently she has started to tolerate this kibble less and less the past few months. she will literally have her stomach growl before eating it now. she's also been a lot more gassy recently. will be switching after this bag.

Something about this food has changed!

My dog won’t eat this food anymore, even if I put something I know she likes on it. I have tried and tried. I am switching to another brand. I still have 2 unopened 40 lb. bags! I have no idea what has happened to it.
