    Kibble too small

    By on

    I think this is a good food, just NOT for large or giant breed dogs. I got this food due to the high ratings and great ingredients. I did not think about the size of the kibble. My Newfie and Mastiff just made a mess of the food due to all the small pieces - they were all over my floor. Plus they just really did not like it. It was not a good fit for them. I have since found a large breed grain free dog food with big kibbles. They love it and there is no mess.

    High quality dog food at a reasonable price

    By on

    This is everything I look for in a dog food; high quality ingredients, no fillers, and, most importantly, my dog enjoys eating it. The cost is reasonable and the shipping is quick.

    Great stuff

    By on

    I put my old Westie on this 10 years ago, after many years of stomach and bowel problems. He did wonderfully on it. I have another young Westie from Finland, and yes, he had stomach problems. I started him on this and he has had no bowel problems. It's great and he loves it. I trust Castor-Pollux. And I love Chewey!

    My dog won’t go near it!

    By on

    I have a very very picky dog, I have had the hardest time finding a dry food that she really likes. I decided to try this one since Chewy no longer sells Acana and it was a definite “no go” with my dog. She will nibble on Organix but Chewy was out of stock so I thought this would work since it’s made by the same company but it didn’t work!! Also there was a lot of crumbs that my dog also hates.
