What breed or mix breed of dog you have had shocked you?

We now have a little Blue Heeler/terrier mix, and she is a fantastic little mouse-catcher ! She loves to play, and thinks that she is the family guard dog as well.
The possum comees around sometimes at nite, looking to see if there is anything he can eat, and Tootsie will run out and bark at him, too; but she doesn't hurt him.
Probably a very good thing, because those opossums have extremely sharp teeth, and if the possum bit Tootsie, it would be a very bad bite.
So far, the worst hee has done is curl up into a ball and "play possum"; so he doesnt seem to be agressive at all.
Wee don't have any mice here, but when we lived out in the country in that trailer house, it had lots of holes big enough for mice to sneak inside, and every now and then one would come running across the kitchen floor, and Tootsie would usually catch it and kill it. [/font]
