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.
It's so cool to learn new things about my fur baby. I knew she was smart but did not know how smart. 
They are an absolute gift to humans! They continue to be employed for their traditional work of herding livestock throughout the world! :)
