IAMS

I've been feeding my dog's Iams for almost 20 yrs! I've had Dobermans my entire lifetime they all lived long lives on Iams, I've used both Iams mini chunks and Iams

I've been feeding my dog's Iams for almost 20 yrs! I've had Dobermans my entire lifetime they all lived long lives on Iams, I've used both Iams mini chunks and Iams large breed my Dobermans and Chihuahuas coats shine and they're always healthy no health problems, this is my 7 month old Doberman she's transitioning from puppy food to the Iams large breed and mini chunks... as you can see she's very shiny and healthy very muscular. I've been giving her half mini chunks and half Iams large breed the vet pointed out that the Iams mini chunks has such a high protein content similar to puppy food that it would be beneficial to use both mini chunks and large breed until she's at least two years old after 2 years old I can switch to only using the large breed for her. All the Dobermans in my lifetime live to at least 13 years old and we're all 120 plus pounds that's a long time for a large dog and they were all fed Iams their entire life!!

Our dog really likes this food. I have chosen Aims on/off for many many years. I am always tempted to switch to those expensive fresh/frozen delivery options & I have tried them in the past, but I seem to land back on Aims products over time. I, also, like that they have so many options these days for special dietary considerations, breeds, life stages, etc. Chewy's autoship option is super convenient too!

Great choice for large, adult dogs

We switched from Eukanuba large breed to save a little bit of money. The other food we used to use that they liked, for comparison, was Blue Buffalo large breed

We switched from Eukanuba large breed to save a little bit of money. The other food we used to use that they liked, for comparison, was Blue Buffalo large breed chicken flavor. So far, our dogs like this food and when we informed our vet of the switch - they said it's a great choice. I searched quite a bit for good quality and price foods for large breed dogs (specifically Doberman's and senior pitt) and this one always came up as a top choice. We have two dogs over 60lbs and one is a picky senior. He took fine to this one. It is also a good choice for Dobies since it is not grain free. We get the 44lb bag since we feed both of our dogs the same food and we love the option for a big bag. On autoship, we get this every 4 weeks with 2 times a day feeding.

I have used various foods for my 10 y/o doggo, including prescription foods. He has always had some digestive issues but I have found that with Iams he is best controlled. I have trusted this brand for over 25 years as my past Labs also were fed the same brand.

I have 2 kids, Buster & Bella. Buster was allergic to many foods & we stumbled upon this from Iams. Bingo! No rashes, very healthy. Bella took to it right off. We free feed, bowl full most always & they don't gorge, eating when they are hungry. Buster is almost 10 larger (90 lbs) mix, Bella is a Pitty about 75+ lbs & 5 yrs old.

I love not having to go to multiple stores to find the exact dogfood that each of our great danes eat. 3 Danes, 3 different foods for their dietary needs. The large bags aren’t always available locally on the shelf and not having to lug them into the cart, then into the car and finally into the house. With Chewy, our authorship order arrives and is at our door.

Economical and Consistent

My dog isn't that picky, but he loves this food. He has tons of energy and a super healthy coat, and even better, it doesn't cost me hundreds of dollars to feed

My dog isn't that picky, but he loves this food. He has tons of energy and a super healthy coat, and even better, it doesn't cost me hundreds of dollars to feed this nearly 120 pound beast. The kibble quality has always been consistent and I've never had issues with a bag. I've been buying this for over 2 years now and I'll continue to purchase. My one nitpick with it is does not contain pre- or probiotics, but that's easy to supplement.

Metal findings

I found this piece of metal in the bag of dog food. Now I'm scared to feed her this but it's all she'll eat as long as I put hamburger chicken with it. I'm still

I found this piece of metal in the bag of dog food. Now I'm scared to feed her this but it's all she'll eat as long as I put hamburger chicken with it. I'm still buying lines but I checked every handful. Chewy is one of the best places you can get your items from but always look in their food. I'm not saying it's chewy fault but you don't know who out. There is ignorant enough to put in an animals food from the factories. I would still recommend the product. But it can happen in any dog food. I'm only putting this here so everyone can keep an eye out. I was so shocked so just always look at what you're feeding your dog. Sorry I don't want to come off rude and if it sounds that way I apologize.

The Name Says It All

Our Great Pyrenees has reached a mile-stone so to speak. We have upgraded her to the next level of food, in which she has been eating this for about 3 weeks now

Our Great Pyrenees has reached a mile-stone so to speak. We have upgraded her to the next level of food, in which she has been eating this for about 3 weeks now. She has always been active but we noticed lately she has a little more activeness to her. We attributed that to the quality of food we have been feeding her. She enjoys her feedings and the food. We have been so pleased with the Chewy family and the quality of the brands they offer customers like myself. We have 3 other Great Pyrenees that will be coming of age, so to speak in the next few months. We have no problem feeding them quality to keep them healthy and happy.

We have a 4 year old St Bernard/Pyranese mix. We started out on a higher priced Petsmart dog food. She was digging up all of our tree roots, and eating them. She was eating the bark off of the trees. We thought, she's bored. We spent all of our time with her, we bought every stimulating toy we could find. After a comment to our vet, just a random comment really.. He figured she had a nutritional imbalance. He recommended we try Iams, for large breeds... Since then, she hasn't touched the trees in any way. She loves this stuff! We won't change food again. Until her needs change anyway!
