Okay here was my uncle's answer to this situation...And before anyone starts in on me...Remember, I'm just relaying the incidents, not abdicating one way or another my opinion on his solution...
My uncle had lots of acerage out in the country here in Texas and many "hunters" used to poach on his property...My uncle lost several of his dogs to the "poachers"...many he had raised from pups (my uncle loved GSD's). One year he lost 3 dogs to hunters and he was given all types of legal advice...including "your dogs shouldn't be roaming during hunting season, even though it's your property they are on." That pretty much ticked him off. He knew people were coming in and abusing the system, several from a town not too far away...but the straw that broke the camel's back...so to speak...was one day he was sitting in the local coffee shop and at the next table were two non-locals bragging how they used this "particular farm to practice live target shooting because he had dogs on the property. It was much better than still practice!"...Since my uncle couldn't PROVE in the court system WHO it was on the property shooting the dogs he decided enough was enough. So my uncle waited in the woods for the "poachers" and when they started aiming at his house to practice on the dogs roaming in the yard, an avid hunter himself he winged those two boys. This happened a few times and his house became known as the place "NOT to practice target shooting"....and just like my uncle, those boys that got "winged" couldn't prove a dang thing in that same court system. Now right or wrong, it helped save the lives of many a dog that lived with my uncle after that...And the law really should be on the side of the landowner, but it's not...so until it is, I know there are a few other people that have been like my uncle...And irregardless of whether or not I condone what he did...I am glad that the pup I helped raise lived out her life with him until old age helped her to cross the bridge and become my 1st angel girl...
