Clever enough, he excels at article searching ie; finding keys etc in the long grass. It's just for fun and sometimes comes in handy for real.

Around work he also uses the drain,he has not yet cocked his leg.
Easier in terms of hygiene but i have never known a dog or bitch do this on the bullseye in the drain everytime.
