I again relate the sweet boy pit I tried to adopt at the SPCA in the city. The puppy cop went by my house and turned me down due to an inadequate fence. I asked how can a dog jump a fence and maul the neighborhood if he is asleep on the couch? No dice, home checks for all dangerous breeds. So I asked about the black lab. Sure, no problem, you want him? No. Said black lab had not stopped eyeballing me the entire time I was in the runs. Complete aggression if you went near his run, but no barking. If let out I had no doubt he'd go for my throat. The vicious pit I couldn't have? Tried to beat me to death with his stub, drowned me in slobber, and peed himself and then sat in it wagging his stub because he was so happy to have some human time.
My only serious bite was from a Dachshund. 2-3 years old and the little turd tried to take my face off. The dog died the same day as my grandfather. No, not a true dog love story, dog went to the vet for the big needle as soon as the old guy passed. Not too many fans among granddad's caretakers.
Tug of war was mentioned. Worst dog game ever, lets the dog start thinking that they are somehow competing for control with a human. I don't care what breed I get they will release their mouth when I tell them to.
