Good quality
By mountainpony on Aug 28, 2020
I don't "break the bank" when it comes to dog food. I try to buy middle to upper quality. This dog food is very good quality and supplies a lot of the vitamins and minerals my Aussies need.

So much gas
By Rebecca22 on Jun 24, 2019
Since starting this food, our dog has the worst smelling gas, and so much of it! We bought a big bag and will be throwing most if it away, because we can't take the smell any longer. He doesn't seem to eat it as well as the food he previously had either.

Not great food
By 2collies on Jun 7, 2019
Based on the ingredients I thought this would be great, not as many fillers. I tried a small bag first and seemed OK, so then I bought a big bag. By the end of the big bag, our dogs had soft stools, horrible breath, and an overall stink to them.

Healthy adult dog food
By AnimalHouse4 on Feb 13, 2019
My 4 year old dog eats the Adult dog food and has for the last 2+ years. I have switched between the chicken and the lamb; the terrier mix does not seem to care or favor one over the other as my older dogs do (they like the chicken better). All of my dogs have very healthy coats and have had great check-ups. I feel I am getting a great product at a reasonable price as compared to some other dog brands.
