You can have a dog that's too well trained ( or too stupid?) . My two wolfhound dogs have taken to sitting as soon as I get the sugar for my coffee from the cupboard. I deduce that this is because, if I give them a sugar lump, i require them to sit on command first. They now do it anyway, either to save me the trouble or to give me a hint of what they hope for.
As related before, I once had a standard poodle which rushed to get outside in thunderstorms, so she could chase the lightning. My mother had a papillon that would rush to the door when the postman came, not to bark at him, but to riffle through the letters on the floor and pick up any which came from me and proudly carry them off. One of the cockerpoos here likes nothing better than to rest in the hearth, and is permanently marked with soot. She even tries this in Winter, when the hearth is cool enough. Nothing compared to one wolfhound who liked coal so much that she'd pick burning coals out of the fire and trot off around the room with them, in a fair impression of the Hound of the Baskervilles. One spaniel took to barking at a fox head on the wall and then ran outside to find the rest of the fox and bark at where it should have been,as it was 'looking in', when the door to the room was shut.
They've been a mad lot here.
