We have irresponsible pit bull owners in the yard diagonally behind ours. I have, prior to owning chickens, gone to the backyard (fully fenced with 4' chain-link) to find a strange pit-bull in my yard...How did it get in there?? More than once, mind you...
I didn't really care HOW, so much as that it was there. What if I had released my 9# mutt? What if my cat got out when I opened to door to go out? What if one of my daughters went out there????!!!???
I decided not to return said dogs, but to call AC. I was fortunate enough to have the animal trapped on my property, but I was ticked and scared. I've called the police, AC and the Humane Society about these bozos because they breed them like mad and I've witnessed them beating on the poor things. Awful owners, not to blame the dogs, but I'm not about to trust the strange dogs, either. I figure getting impounded was the poor things' best chance!! We have a no-kill shelter.
If I had this problem, back to the original post, I'd get a paintball gun, a X10 video camera hooked up to a VCR, and I'd annoy the living crud out of AC every time there was a sighting ONE INCH on my property line. I'd definitely dose a tasty morsel of food with downers(the appropriate amount for each dog) and FEED IT TO THEM!!! By hand, if necessary, to avoid unintentional collateral damage. I'd offer treats and be sweet as honey to the things until they keeled over dopey(or lounged, anyway), and then go call AC and demand their impound, explain the situation, and insist my property was protected- not their business how the drugs got into the dogs. I had drugged meat in my yard for *my* business, thank you! MY yard!!
Last ditch, I'd live trap and take to the pound 2 towns over. The gene pool doesn't need the Ditzes' input, btw- I agree it's too bad they got to breed.
Jerks.
