I think Diesel will do well on the Artemis, just remember like Erin said, make the transition slowly, so as not to upset his sensitive tummy. Kia did not care for Innova, the bites were too thick for her tiny mouth, and Canidae gave my girls the worst breath!
Artemis is the only food Kia doesn't bat out of the bowl to eat, she gobbles it right from the bowl.
