We love IAMS
Flavor Name: Chicken Size: 30 Pound (Pack of 1)
This IAMS large breed mature dog food has been a solid option. My dog eats it without any issues and seems to do fine on it. The kibble size works well for larger dogs, and it doesn’t upset his stomach or anything like that. Coat and energy seem normal, nothing negative to report. It’s not a fancy premium food, but it’s consistent and gets the job done. ... show more

Great food for older dogs
Flavor Name: Chicken Size: 30 Pound (Pack of 1)
I reorder this every 3 weeks. Packaging is always perfect. Great for my older dogs. Really helps with their joint health. They have no issues chewing. It doesn't smell bad like some of the other joint kibble.

Perfect switch!
Flavor Name: Chicken Size: 30 Pound (Pack of 1)
My dog is getting a bit older and the regular Iams large breed didn’t interest him anymore. Switched to this and he is eating regularly again and seems much more active.

My dogs loved this dog food but seller doesn't have "subscribe" option anymore. I had to change to a different flavor.
