My dogs have been enjoying ToTW for a few months now- my senior border collie has quite a tricky gut and is a garbage hunter, so it's a relief to find a food that is actually appealing to her and easy on her stomach.
My BC mutt, Jack, gobbles it down unlike any of the food we've tried in the past and his coat and ears smell a lot better than when he was on grainy food.
As a side note- when I first started buying ToTW, both dogs had nasty fish butt. My husband insisted it was the salmon food and requested that I discontinue it immediately, so I switched to the bison brand- but still, fish butt persisted! I was about to do away with it for good and try another brand when, lo and behold, my sister shared the fact that all of the cat food in the barn had been raided- several bags of dry and a few boxes of wet packets had been chewed and destroyed! I had no idea she had been stock piling cat food in the barn, but apparently my dogs had found it and were enjoying a "buffet" every time they were in the barn unattended. D'oh! I'm so glad I didn't take the dogs off ToTW, but I'm also glad they are now fish-butt free (and the cat food is on lock down).
