Your absolutely wrong, why do hounds chase bears and mtn lions. Because there trained to and like it, unchecked and they will start chasing other animals.I bet your dog doesn't chase animals for fun either. Dogs chase animals because they are starving, therefore anyone who owns a dog must be charged with cruelty to animals if their animal chases something....there can be no other reason for it. After all, why would a tame dog chase an animal for fun but a wolf would not?
Stock dogs same scenario.
