Sophie Enjoys

My 5 month old Great Pyrenees seems to love this food. She is always eager for meal time and is growing perfectly on track for her breed. A healthy 45 pounds at 5 months old. I like that it’s a brand I know and the first ingredient isn’t a byproduct.

Beyond satisfied

The ingredients are great for this price. We’ve been using this food for our border collie since he was 2 months. He’s 7 months now and with this as his primary food he grew bigger than we expected. He has also always looked healthy with a beautiful shiny coat and has lots of energy. We are so pleased with this particular food that we plan to use it all the way up to 18 months.

Iams Large Breed Puppy Food

I appreciate the fact that this was delivered in less than 24 hours to my front door. The large bag is so much more economical than buying the smaller bags.

my golden loves it

My golden retriever puppy loves this food. She was having some digestive issues with the food the breeder gave, this food was an easy transition and no issues what so ever. She is a healthy weight, extremely active and healthy not to mention her poop is perfect on this food. Try it!

Great food

We got a puppy recently, and I was worried that he wasn't growing as fast as he should be in his old puppy food. Talked to his vet during his first visit and this was recommended. I didn't even realize they made puppy food specifically for large breeds (Brutus is a mastiff/pit bull mix) He looked so much healthier after even a few days after switching and was so excited to eat this over his old food. He even stopped abandoning his food to steal his sister's.

Ants found in Box!

I opened my box that my puppy food came in, and there were ants all over the bag and inside the box. They ended up getting into my house and now I have to spray to ensure they don’t go elsewhere. I never had this happen before, and I am sure it isn’t something that happens often, but I was shocked at the amount it tiny ants that were inside the bag and box. I had to throw all of it out.

Good Puppy Food

Great starter food for puppies. Puppies do well on it, start mom on it, a week or two before puppies are born, so easy transition to puppy. Easy to find food, so puppy people don't have to search around hunting "weird" brand of food to feed, although I do send a container along with the puppy when leaving.
