I have two border collie dogs, do you like them? They were specifically bred for intelligence and obedience! 
Yes, I actually used to have one. He now lives with my ex girlfriend. Do you work yours? Ours worked on my horse ranch.
No, i live in the city :) I love them though, they're even considered as the most intelligent of all domestic dogs.
Yes, mine could go to the fridge and bring back a water bottle then head out to work the horses.
That is actually amazing! i need to teach mine how to do that haha. As well as intelligence, they are also extremely energetic, acrobatic and athletic. They often complete with great success i sheepdog trials and dog sports so its no surprise that yours were good at working the horses.
