Pretty impressive. Mine can jump pretty high too. He just hasn't learned the landing part too well. Been some times he's hit the ground and I've cringed, so I try to not let him get that high. Nice shot though.
Lucky you having never had anything more "lame" in your life than to have to explain that you are not a spambot/dog fighter/ anti pit bull on a pit bull internet forum!
There's a sample intro here:http://pitbullforum.com/viewtopic.php?f=17&t=64327 that will describe a bit what we're looking for in an introduction. When that's done, one of the moderators will likely approve you.
