I knew a standard poodle that could climb trees. I saw him do it, and scare the crap out of a cat.
I had a German shepherd that was highly dumb and ate everything, including Barbie dolls, the sofa, and the fence.
My mini Doxie is super-smart, and even has a sense of humor.
My Lab can climb a 6 ft chain link fence.......whenever he wants..........
Speaking of standard poodles, I saw one pass its HRCH. It caused quite a crowd.
I also saw a Boykin Spaniel get its HR. That had a bunch of people scratching their heads.
