I buy aldi's dog food, the cheapest on the market, she eats a bag about once per month. I feed her a bowel maybe every 3 days and only when she is begging for it. During deer season she prefers the dead deer guts in the woods and she may not eat dog food for 1-2 months. She also likes eating mice sahe catchs. Coyotes are very much like dogs and live on mice mostly.
