I posted like a bagillion pages ago, but I actually kind of completely forgot about my childhood German Shepherd, Sadie.
She was an extremely unstable dog. My dad got her for me when I was 10yrs old so we bonded. And that was the problem... she became SO protective of me. By the time she was 3, she had bitten (that I can recall) my step-mom's father, one of my close friends, and two of my dads friends. And last but not least, at 4yrs old, she attacked a man who came onto our property to check the oil in our house.
All of these were our fault. For the most part, we managed very well, but I forget sometimes how difficult it really was living with her. Any time we knew someone was coming over, we finally started locking her up in the bedroom, but well... people are stupid. When she bit my dads friend, it was because he claimed "every dog loves me" and decided to let her out. He reached out to pet her and she bit (but let go quickly). That was forgiven. My stepmoms father once went into a bedroom where he did not know she was and she got him, but he closed the door quickly enough to not have too much damage. My friend, who was 13 at the time, was being obnoxious and jumping up and down on my bed and Sadie went after her. The last time, she was off leash in an unfenced yard and we did not know the service man was coming to our house. She full on attacked him, puncture wounds, etc, and he had to call AC since he was on the job. They put her to sleep that day. I think they basically told my dad that he was obviously getting cited or whatever, and she would now have a bite record, and if it happened again, there'd be huge fines and a whole mess.
But my dad being the kind of person he was, wouldn't have put her down had that not happened. And he would've continued living the way we did.
But with all that said, my brother Camron was born about 8 months before she was put to sleep... we honestly never even worried about it. She never cared at all about the new baby and if anything, was very protective of him. So that was the main thing we were worried about -- we would put her away when visitors came over because we did not want her thinking they were harming the baby.
But it WAS very stressful from what I remember.
