The 7 pound bag contains approximately 28 cups, the 15 pound bag contains approximately 60 cups and the 29.1 pound bag contains approximately 116 cups.

The bag mentions glucosamine and chondroitin but neither is listed in the ingredients or nutritional info, are those actually in this dog food?

dog food puurchaser

I started using this dog food in October when Hills Large breed Senior dog food was unavailable and also had a big price increase. In 75 days I have noticed that my dog smells, has bad breath, loose stools, less energy and more inflammation. I have just reordered the Hills Sr Lg Breed dog food for my dog. He is worth it!!!

great order, not so great delivery

My order came during a rainstorm. I put a wheel barrow next to the gate so the driver could drop it in. Instead of dropping it in the wheel barrow they dropped it next to in the pouring rain. I'm 70 y/o and the pkg weighed almost 60#'s.

Transition to food for older dogs

Nina is definitely starting to show her age. She is slowing down due to some arthritis and putting on a few pounds. It was time to switch foods. I was worried Nina would not like transitioning to a food for aging dogs. She did a lot of smelling of the food when I first started mixing it with her usually IAMS Minichunks food and then started to eat it slowly. I guess she liked it because she gobbled it up. There were no digestive problems or upset stomach. She loves it.

Good for smaller dogs too

I'm always nervous about kibble bits being too big for my 15# shih tzu. These aren't tiny, but definitely are small enough that she can comfortably eat them without issue, even missing half of her teeth! After about a month, we've seen improvement in coat and skin health. She's on meds for arthritis, so I can't really speak to if the food is helping that, but it definitely hasn't hurt!

We have fed IAMS foods to our puppies, to our younger labs and senior labs for over 16 years, and all of our pups young and old have always been, and are now, very healthy. Having the convenience of CHEWY in addition, just makes it a no brainer. At this point, we will continue with the total plan as long as things remain the same.

Les than desired

I have to overwhelm the kibble with gravied canned dog food in order to get my dogs to eat it. Less than spectaculer...

My old dog loves this.

Mischka is about 15 years old. She is a bit of a finicky girl and she's absolutely loving this food. I hope it doesn't get more expensive as I'll be ordering this again.

My dogs love it!

Both my dogs are 10 and have been on senior food for 3 years. I just switched them to Iams and they love the food! They literally jump at meal time. Happy dog mom!
