Looks good, but not in this house

Chewy was out of my regular food, after research this looked good on paper so it was worth a try. After working on the transition to this food, the one dog started eating her own poop. I backed off on the mix and she stopped. I quickly bought a bag of her old food and put her back on it, and no more 'recycling food' from the yard. Since I had the bag, I thought I would try again to mix them to at least use it up and every time I get about half mixed, she and the puppy started eating her poop. I dropped the bag off at the shelter to get it out of my house. I wish it worked, it looks like a good dog food but I just don't like the end results.

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.

Not sure what this is

I bought the wrong size of kibble I usually get large breed , was afraid Onyx wouldn’t eat it but she gobbles it right up

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.
