Rated 5 out of 5 by from Great Features I love this dog food and so do my dogs they love the pork flavor not the chicken I just have picky dogs that are sensitive to everything. I hate that every store I go to does not carry the pork anymore it is all chicken. Why can I not find the pork flavor anywhere?

Rated 5 out of 5 by from Growing strong I've had both of my dogs one is a Doberman and the other a Rottweiler on IAMS since they were both 8 weeks old. They've been doing great on it. Their coats are shiny and they're both very energetic! I personally like it because it contains chicken as it's 1st ingredient and it's not that expensive compared to other brands. My Dobie is 2.5 years old and my Rottie just turned 2 years and I plan on keeping them on IAMS for the rest of their lives. I'd definitely recommend because of the reasonable cost and quality. I'll be updating reviews as they get older so far I'm satisfied!

Rated 5 out of 5 by from IAMS & CATS 15+ YRS Our family has used Iams dog and cat foods for over 15yrs. Many yrs ago one of our vets recommended Iams saying it was high in protein as well as containing other better, healthier ingredients and had fewer fillers. He also commented that because of better ingredients, the dog and cat's fecal waste was in smaller amounts and the waste didn't smell as foul. We noticed these two bonuses immediately! Our pet's fur ALSO became VERY soft and shiny. The two cats I've had over the last 15 years have been SO soft to the touch like silk. I would positively recommend Iams dog and cat foods. I've only used the dry foods so I cannot vouch for the wet foods. You will not be disappointed in Iams pet foods.

Rated 5 out of 5 by from The best!! My German Shepherd turned up his nose at Diamond Large Breed, Nutro, Fromm, and ProPlan across a span of two years. He LOVES this food! I'm so happy to get the extra nutrients specific to large breeds and relieved not to have to add or top the food with some kind of enticement. I have had to throw away so much dog food, because I didn't find it true at all that "if he's hungry enough, he will eat it". Maybe not every dog will like this, but my very picky and spoiled dog loves it!!

Rated 5 out of 5 by from Best dog food for my German Shepherd I started buying her the large breed puppy food and she loved it! She did very well on it and grew to be a big dog! When she was two years old, I gradually switched her to the adult large breed formula. She is thriving and very energetic! She is an indoor dog, but obviously gets her outdoor fetch exercise! I highly recommend this dog food and so does Jet!!

Rated 5 out of 5 by from Proven Quality over years of use I have raised several dogs using Iams and have had healthy long lives. I have had people suggest I not use this product but then they go on and tell me about all of their vet bills. My current Lab I rescued from a family that couldn't handle her. They gave me a supply of their cheap food which I used to gradually change her to Iams. She changed physically and mentally to a much happier dog.

Rated 5 out of 5 by from When confirmation is important Having had numerous short haired purpose built hounds I have learned a lot about food. Having tried everything from generic to small batch designer kibble and home made raw meal to Alpo the truth eventually comes out. My dogs: coonhounds, Ridgebacks and an occasional pointer have the best combination of muscle confirmation, energy, overall health and brain power in Iams kibble. This statement extends back 36 years to when I started using it. And that product had a fault, 4% or so too much fat. This product repairs that and remains free if criticism. Well, I do complain that the one folks at Iams no longer make charcoal biscuits.

Rated 3 out of 5 by from Ok I received this free from Pinch me and Im glad that I did. I had been considering buying it for a wile but when I ended up giving it to my dog I saw no difference and I was a bit more expensive then my old dogs food so I will continue to use the original food I had.

Rated 5 out of 5 by from I always recommend Iams I've been using Iams before it was even sold in the stores. I've never had any issues with my dogs that were related to the food they were being fed. I always recommend Iams. Dogs love it, it's affordable and safe for them.

Rated 5 out of 5 by from My dog could not get enough I have never seen my dog eat like he did with iams. He could not get enough and it seemed like he was begging for more!.... so I guess we have officially switched brands..
