I changed to this food on the advice of my vet, and it has been a disaster. After the transition was complete, my dogs (a Labrador and Bulldog) stopped eating it all of a sudden ! My Labrador will eat almost anything, so I concluded that this food must have a very particular taste. It's a shame, I've been left with a huge bag of food and I have to switch to a different brand, it would have been good to have been able to try before you buy.
Something or other in this food made my dog reject this food. Even though she has an anxiety disorder that normally makes her eat everything in sight, she went a day and a half without eating rather than eating this, which she completely rejected. I had to give it away.
