THE DINGOS ATE MY BABY!!!!!!!!!
Seriously, the first thing I would do is talk with the local law enforcement and find out the legality of shooting "ferals"......in some places, it is illegal to do so, irregardless of whether or not they are on your property, chasing game, etc. About the only time you can shoot a dog is if it is coming after YOU, and you better have several reputable eye witnesses. More than one person has been caught doing this (shooting ferals), and the end result is a lot of $$$$$ payed to "owners" (irresponsible owners
), and of course, it was their daughter's beloved pet & now she needs therapy, or it was a grand champion show dog that was worth a million billion dollars, blah, blah, blah. You know the drill.
Besides that, people take a dim view of shooting dogs......doesn't matter what type of damage they were doing; you should have called a vet and got a tranquilizer gun and then had the dog spayed/neutered and found it a good home afterward. If you shoot it, your just a heartless bastard (never mind that the original owner dumped the dog and left it to starve).
Been through this whole issue with feral cats; fortunately, they aren't as beloved as dogs......but still, we got NO pleasure from having to shoot 20+ cats in a year because they were dumped on/near my Aunt's farm. She would feed her two, but then the damn strays would show up and take over.......used to have barn swallows in the milking station and purple martins in the yard....the ferals made short work of those, and then started on the local cottontail population.
Good luck......I'm glad I don't have your problem.
On another note, where do these idiots who think "spay and release" of feral cats get there information?? Just how is this supposed to be a "good idea"? The are still vectors for disease (including rabies) and still menacing wild bird populations.......and people just dump more strays in the same area
