That's kinda where I'm at on it.That is just wrong. That one should have joined the Shepard in doggie heaven.
Bad Joo-Joo.
I'm not really against APBT as a breed. Yeah, they probably are inclined to be more aggressive (and maybe even provably so). But also, nurture can go a long way to mitigating that particular part of their nature in any particular dog. "But mine just loves people" is totally believable to me for any specific family dog. Doesn't mean I won't be leery of it, but I can accept that people believe that about their particular APBT.
For purposes of that anecdote, though, I don't care what breed it was. If it goes after a GS (even an elderly one) unprovoked and does real damage, that's a problem dog. Like, unfixable. At the very least, untrustworthy around any one. And if you can't trust your dog, I can really only think of a couple reasons to keep it around. And neither is particularly kind to the animal.
