Had one for 16 years, another for about 5 years.
Mine where good with kids.
And plumb danged mean to a drunk that happened to stagger on to my carport at 0200 on a Sunday morning. It was not pretty to watch. Keep telling him to stop, he wouldn't stop. He continued towards the door waving his hands and hollering at me. I let him set his foot on the carport slab. Had my female catahoula dog by the collar, she was snarling and growling. When his foot touched the slab I gave the collar a twist, told her "get'em". She was not trained, figured at most she would nip him, maybe and bark getting his attention making him back off. She hit him at a run leaping up just as she reached him, her front paws hit him in the chest. Knocked him flat, then she began to take nice large chunks out of what ever part of the body the guy offered. He scrambled to his feet and my last sight of him was going down the driveway with his back pocket ripped nearly off. Daphne, my sweet family dog, giving him a bite and head shake every few feet. Some strange reason he was still hollering and waving his arms. To this day and it has been over 10 years ago, I do not know who the drunk was, nor have I heard from him again.
