What's this boxer good for?

[model 70]

that brings up a good point. when i give my predator call a blow at home, both boxers i have go crazy. they start barking and lunging at my face since that's where the call is. they don't mean me no harm, i know that for sure. they really do hate the sound the call makes. came home one day and found what they did to my circe rabbit in distress call. killed it.
