I had fed my two bullmastiffs raw for the last year until it became to expensive, so after thorough research, we switched to Acana, the next best thing from raw food. Being that my dogs are massive and love food, they gobbled the kibble up quickly. Love that the quality of the food is top notch. The dogs are fed less quantity-wise compared to other kibble brands. The only con is that it is almost just as expensive as feeding raw.
