Very interesting, I remember a while ago I was watching a special on dogs and they did an intelligence test that consisted
of putting a towel on their heads and timing how long different breeds took to get the towel off and also putting food
under one cup and not under the other one and showing it to the dogs and they were judged on that and at that time
on the list the poodle was number one and the German shepherd was number two and on the bottom of the list
was the Basset hound, but yet you would not have to worry about separation anxiety with a Basset hound either.
