Rated 5 out of 5 by from Dog loves it those who want a review of the contents the bag and not the bag itself, my dog likes it. He eats it twice a day and I’m thinking and hoping I am giving him a good quality food. Now for those who want or based their reviews on the bag the food comes in. Yes, I agree you can’t open it with your hands but I own scissors that I open the bag with. If you don’t own a pair, I’m sure you can buy a pair from target when you pick up your next bag of dog food. And as far as the bag ripping, I also purchased a large apothecary jar (yes, from target!) that I keep my dog food in. This actually keeps it more fresh than a rolled down bag(just a suggestion)

Rated 5 out of 5 by from Trusted nutrition I have had my dogs on Iams for a little over a year now. we have small consistent stools, nice skin and coat, bright eyes, good cognitive skills and maintain a healthy weight. I train my 2 dogs for mobility service so the benefits of this premium dog food matters greatly on their performance. The senior dog is retired but the training continues to keep her happy and engaged. I do buy two different recipes, senior large breed and the adult large breed.

Rated 4 out of 5 by from Good Product I have an older large dog, so I'm always on the lookout for new items for her. The first time I gave her this type of food, she gobbled it up. However, going forward, I had to mix her other food with it. It's a good item to supplement with.

Rated 3 out of 5 by from It's OK So I'm pleased to see that the first ingredient is chicken. It's an OK dog food. My golden retriever loves the change in food, and it's agreeable to her, but does no compare as well to other foods that we have given her. It's good, there are worse foods out there, but there are also better options. Good for the price point.

Rated 5 out of 5 by from Fur Babies Loved It! We normally purchase Rachael Ray for our two fur babies, one of whom has a very sensitive tummy, and cannot tolerate many of the low-end dog foods with lots of fillers and junk in them. We have to be very careful what he eats. The first thing I did upon receiving this was to check the ingredients and nutrition chart. I found only good things!! And they both love it!

Rated 5 out of 5 by from Dog enjoyed every bite My senior bulldog is very picky with what he eats. I have been a Pedigree user for years but as he gets older I know he needs extra nutrients and minerals to help him live as long as possible. This particular brand was great. The pieces are ideal for older dogs with less teeth, made like mini pancakes he had no issue chomping them right down. I noticed he was very chipper when it came to feeding time each and everyday. He seems to be getting up more and moving around outside enjoying the fresh air and even running a bit with the younger dogs. When placed beside a bowl of his previous brand he went to this one and ate every piece. We will continue to use this and hope he loves us out a while longer.

Rated 5 out of 5 by from my dog loves this food This is a great brand of dog food for adult dogs. Easy to digest for my larger breed dog. I switched to this brand and will continue to use this product for my dog . As it provides a great source of nutrients for my fur baby.
