I am not sure whether Kailee would or not, thus far she has not shown any real protective instinct. Heavens if the doorbell rings she just looks at us, then hides behind us until we let them in. But, like Buddy, I always like to think if I needed her she would be there for me.
Buddy was extremly laid back, never ever showed any aggression or protectiveness either ,until one day. My niece, as usual, was staying with us (She was about 1 at the time). Buddy and I were in her room tucking her in for a nap. Once she was settled, we came down the hallway towards the kitchen, and lo and behold I found this VERY strange man standing in our house! Needless to say I was somewhat freaked, and without Any hesitation Buddy reacted on my reaction and took over! YeeHaw!! He backed that creep right out of the house, letting the guy know he meant business. Once outside he knocked the man down and sat on him. I called the police, they came, the man gave some idiotic story about thinking it was someone else's house, and he got charged with trespassing :( Buddy did not hurt this man, just scared him and let him know who was in charge. I knew from that day on, although he was very gentle, he was there if I needed him. That was however the beginning of his habit to pounce at the door whenever someone knocked or rang. Didn't bother me though, cause I knew he was doing his job

Although Kailee has yet to show the need, I think perhaps she would if she had to.
