Questions & Answers

Where is Iam's manufactured? Where do the ingredients originate?
Answer by ChewySep 22, 2017
All of Iams dry dog food products sold within the United States are manufactured at their plants located in the United States. Their ingredients are carefully selected for the health and well-being of the pets they feed. For this reason, they're committed to sourcing ingredients from suppliers located near their manufacturing facilities when possible. Like most other pet food and human food companies, some vitamins and minerals are supplied by their trusted partners in China. Rest assured they're confident in the ingredient integrity of all of their suppliers because they demonstrate the ability to consistently meet the strict and thorough standards of their own Supplier Quality Assurance program, regardless of where they are located. As a key part of this program, their suppliers undergo frequent quality audits to ensure expectations are met.

Our Boxer just turned 1 and weights 58 pounds. Should we transition to this now from his Iams ProActive Health Puppy Dry good?
Answer by ChewyMar 31, 2021
Your puppy's transition to adult food should begin when they approach adult height. Their breed type will also help determine when to switch. Small-breed dogs tend to mature physically much sooner than large-breed dogs. Small-breed dogs that weigh 20 pounds or less when fully grown are usually ready to eat adult food at 9 to 12 months of age. Medium-breed dogs that weigh between 20 and 50 pounds as adults normally mature at 12 to 14 months of age. Large- and giant-breed dogs, those weighing more than 50 pounds when fully grown, might not be ready to switch to an adult food until they're 12 to 24 months old. Please consult with your veterinarian if you're unsure.

Are the kibbles the same size as the puppy ones? They look to be the same size on the picture.
Answer by ChewyMay 19, 2019

Good stuff

My 100 lb, 29 in tall, 10 yr old Malamute/ high content wolfdog has been eating this all his life. Still healthy and smart as can be. A stray wandered in 9 months ago. Suffered from malnutrition and dehydration. He looks to be a Husky/low content wolfdog. Had no hair on his belly, no under fur and skinny as a rail. He's about 3 yr old. He had been living on pine cones and a broad leaf weed he seemed partial to. Today, his diet consists of Iams and table scraps. He has gained at least 30 lbs. His coat is normal now and he is very energetic. A friend passed 9 months ago and my two dogs adopted his dog. A Shepherd/Healer mix, he was at least 30 lbs overweight. This guy has lost 35 lbs. His feet used to hurt after short walks. No more. He, like the other two dogs, has had a diet of Iams and table scraps since under my care. Yes. We do walk and play everyday. Diet and exercise mean everything.

dogs don’t like it

None of our dogs liked this. They will only eat it if they are really starving or if we put something (gravy or cheese) on top of it. We tried both the chicken and lamb. Big no.

Great dog food

I have a 85 pound German Shepherd/Boxer mix and he loves the size and taste of this food. Plus I've noticed an improvement in his coat, less shedding.

Dog food for two canine dogs

Dog food for two canine dogs. I have tried other food that was healthy but it did not agree with their stomach. This dog food and they seem to love and have never had any problems in their coat looks great.

I love this product an also my dogs do too

We switch to this after taste of the wild was outta stock.. best decision made. My malamute an husky crave this up. And the best thing is actually that they have a 30lbs bag and not 28lbs ... ordering again.

Love the service!

I am older now and am the sole shopper now. Buying large bags of dog food was getting harder. I don't know why I didn't start ordering from you before this. We have had Mastiffs for many years and find that Iams is an excellent food for them.

Best food!

I have been feeding my dogs Iam’s for years. Now with the pandemic and not being able to find iam’s, I had to put them on whatever I could find. Unfortunately it was some holistic stuff (seemed to be the only stuff that was stacked on the shelves). I raise shepherds and food is expensive plus they need a solid food to fill them up. Iam’s I hope that your back and stay in stock because your the best for me and my pet family!!!
