How about the Pennsylvania SPCA humane officers led by chief George Bengal (and soon to be featured on Nat Geo's Philly Undercover)? Just yesterday, the eve of Christmas eve, Bengal and company busted an illegal dog breeding operation and rescued 26 dogs in the Olney section of Philadelphia. The two individuals facing charges, James Hines and Denekei Lawson have a string of past animal abuse charges between them.
So consider this: where township lines meet, your pet may be safe on the side of the street in the municipality that's paying, but God forbid he runs across the street where, providing he's not hit while doing so, he is on his own.
Animal control highlights the depth of the dysfunctional and fractured governmental system in Pennsylvania (see Maryland for how to do it right.)
