Need help
Why do your distributors not carry the dry Adult Dog food? Sams keeps sending the minichunks, I have large dogs, they don't even chew the small bits. They used to carry the large dog, but not anymore from. What I can tell. Also, why can I not find the 50lb bags. And why can I not just put my name in the nickname slot? My name only has 3 characters.???

It has always been a stable dog food, unlike many
I fed IAMs for many years when I was a K9/trainer and I never had any problem with my dogs.

Great product!
Packaging came in great condition, the effectiveness was great there was a lot of food in the bag itself, the durability of the bag was excellent happy with the way it came, sizing was good great for big dogs like my Great Dane mastiff to know the size of the food so she doesn’t choke, overall the value of this bag was spectacular and very happy with this order will keep purchasing it!!

Great taste without the weight gain!
We are an IAMS dog food family! I had a 16 year-old dog that strictly ate IAMs and after she passed, we continued the tradition with my girls today. As you can see the dog food does not make them gain weight, we feed ours about one cup two times per day. They absolutely go nuts anytime I bring in a new bag of dog food!

Dry food for large dogs.
Dry food for large dogs with real chicken. Large economical packaging. Specially developed balanced nutrition for our pet. Our dog always runs when he hears food pouring into the bowl. Our dog is healthy, cheerful and happy. In a package of 30 pounds.

Great value great food!!
Amazing food and such a great deal!! All my dogs love it and it does well with their digestive systems. The packaging is always easy to spot in the bright green bag. I love how much you get for the price so I can feed the strays if need be. They love the scent as well every single time I feed them no matter where they are they come running!! Great real ingredients that I feel god feeding them!!

Iams Dogs are Healthy Dogs
My large (100+ lb) mixed breed dog lives to be nearly 16, eating nothing but Iams Large Breed. She lived a super long and very happy life, her weight and bones remained strong until the very end.

Great product
We have always used this brand for our Saint Bernard and he loves it :) He always cleans his bowl. I like how it’s specifically for large breed dogs

Great dog food for my multiple dog household.
My dogs have been eating Iams dog food for years now, every dog loves the food, no issues with this dog food, complete and balanced diet which doesn't break the bank completely especially with having multiple dogs.

Information should be free.
I can't find the price out on this website. It wants to harvest all of my information instead of posting an honest price.

My dogs favorite food
This is the food that my dog eats everyday. She loves it so much! She runs to her bowl every time we put it out to her. It is a great price for what you get.

My dogs aren’t fans!
Purchased while on sale and slowly integrated into my dogs daily feeding. Unfortunately, it gave my pitbull very bad gas to the point where he stopped eating it completely after a week (very unlike him).

Dog loves it!!
My golden doodle Murphy loves Ian’s dog food! It has great ingredients and doesn’t upset my dogs stomach at all which is something we’ve struggled with in the past. And It’s an affordable price!

Not worth the money
We tried multiple flavors of this and it created digestive issues in our dogs. Not a coincidence that multiple dogs couldn’t handle the food. Save your money and do your research!

Good for doodles
My two golden doodles loves Iams! They run to the bowl when we feed them. It is also very good for their digestive track. We noticed a big difference in their bowel habits when we started feeding them this brand!

Good product
My dogs have always enjoyed this food. I normally buy them Diamond brand because it was recommended for their particular breed. However, Diamond Naturals is somewhat hard to find in my area and typically has to be ordered online. Iams is my backup brand as it has similar ingredients, is affordable, and can be purchased at my local grocery store.

A faithful standby
We’ve been feeding our pups Iams for years! It’s a great standard kibble; sometimes we spice it up by adding a few squirts of salmon oil on top for skin and coat health.

Dogs Love!
We’ve been an Iams family for the last 16 years. This is what our vet recommended and our dogs love it. We currently have two black labs and they get very excited at meal time. Spins and giving paws, it’s very cute.

So happy to hear that your pups give IAMS a paws up! It's always rewarding to hear when our furry friends are excited for meal time!
