Yes. I have 4 ambulls, the one biting her, the one she laid on and the two in the crate by the back door. The one she tried to jump over is a rhodesian mutt and I believe the boxer was laying on the couch.
The big one that she laid on is protective. She's not aggressive at all unless she feels necessary. She has run up at me full speed when I was facing into the wind at night. She knocked me over, but realized it was me by scent in time stop her attack. I was trying to suprise her, so she did exactly what I wanted.
