Hmmm, my dog is half boxer and half pit bull. So he's kind of like a hyperactive, mischievous, pit bull.
He's pretty good with most people but let another animal come around he'll be going after it. Just like a pit bull too, he goes for their neck. He's not that big, only 24 inches at the back but damn he's strong. I've probably been through $50 worth of chains. Any regular dog chain I got he would snap in a few days. I finally went to the hardware store and bought some big chain like you'ld pull a car with and some huge snap hooks on the ends. I sunk a post hole about 3' in the ground and filled it with concrete and put 12" eye bolt in the top. That seems to hold him so far. Not that I keep him chained up all the all the time but if he's been bad he has to pay the dues. When I mow the lawn I have to chain him up on the patio. He attacks lawnmowers too.
I bought him as a pup from a guy on the street corner for 5 bucks. I think I know why now.
