I have 2 pure-breed black labradors and they're why labs are my favourite breed, though they both are complete contrasts to each other.
The big one is pretty smart, I mean I don't know anyone else's standard for smart pets but this one can 1.open doors by himself and once actually closed it
2. can wake me up, lead me downstairs and into the kitchen for me to feed him breakfast(this has only happened twice though) and
3.finally he sleeps on MY BED if I'm not in it before roughly 11 o'clock(again, pretty rare).
though the smaller one is a complete idiot and I wouldn't have him any other way for example
1.he sometimes walks into walls without the other one with him.
2.once tried number 2 of the smart dog's list but instead fell down the stairs and probably farted in my room(at the time i didn't even KNOW dogs could fart)
3. whenever I play catch with the two of them the smart one will try to get it before the ball hits the ground but the small one will wait until it hit's the ground and sometimes ithit's him on the head and he doesn't even FLINCH
