My Yorkie's LOVE this food, and I LOVE it for their health.

I had to change foods last year due to my eldest Yorkie showing signs of aging, emotional well-being. I first tried Salmon based as I read that it is good for brain health. Even though it was a high quality brand, it did not do much of anything to help him. My Vet recommended this food and I will tell you that it made the world of difference in less than a couple of months.

Iams Proactive Senior Formula Dry Dog Food

I have been giving my dog Iams dry and wet food for quite some time but now that she is getting older, I decided to try the Senior Formula. She seems to like it and is doing well on it.

Picky eater likes it

We have two and the older will eat anything but his younger sister is more particular. She likes it better than the Lamb/Pea grain free we were using. Switched because our Vet said to move away from grain free.

Great Food

My only complaint is the box was way too HEAVY!! Then they only put one piece of weak tape on it and it always comes busted open. If you’re going to put all my 30lb bags in one box, at least use the proper amount of tape to keep it in tact!! Had to keep flipping it over and unload the box outside!

Change of formula? Dogs are not happy

Iams customer for over 10 years. Moved to the ageing formula a year ago and my large breed dogs were fine with it even with the large chunks. Now it's in smaller chunk kibble and they're not eating nearly as well. Poop is quite smelly now as well. Watching Iams prices go from $30 to $45 a bag in 2 years I'm concerned that shortcuts are being made now. Starting to look for other options.

Faster than expected

It came next day. I guess I don’t have to worry about last minute purchases because chewy is on it!

Finally, a food she'll eat

My vet recently told me I should feed my dog a non-grain free/senior food. I tried several brands and she wouldn't eat any of them. She likes the Iams and has been eating every bite. Now, what to do with all the food she won't eat?

Not well liked

My pups only ate some mixed with wet food, so i got more. Then, they wouldn't even touch it, even mixed with their favorite wet food. I'm giving up on dry food, lol.

My 12 year old loves this food

Bella is a 12 year old Bichon Frise. The IAMS Healthy Aging keeps her spry, her digestion on an even keel, and her stools firm. What more could you ask for?

Favorite Brand

Panda & Bella get Iams. Bella is turning 13 next month so she is an old gal. We switched her to this formula. She has an easier time chewing it and seems to enjoy it more.
