How much does an adult pit bull eat a day for 22 pounds? Usually, the dog food instructions have the corresponding feeding amount for different weight dogs. Generally, an adult dog of 22 pounds can eat 230g/day of dog food. If your dog’s main food is not dog food, then there is no ration for how much it eats a day, and each dog will eat differently. If his stomach is full after each feeding, but not too hard, then the amount is just right. If it’s hard, it’s too much, and if it’s deflated, it’s not enough.
