That's horrible. I deer hunt w/ dogs in Central VA on a friends hunt club and I keep and own 8 rabbit dogs and no one should shoot someone elses dog in a situation like that. If my rabbit beagles run onto someone elses property, I try and retreive them as quickly as possible. I know deer dogs can run a long way out but my buddies who run them run tracking collars on them and all the clubs around them are polite w/ each other and catch each others dogs if they run over there and call and return them as quickly as possible.
