You should talk to @RossDCurrie. He adopted me when I was 18 months old and I am certainly a handful... totally worth it though! (I think!!)

German Shepherds are totally a high maintenance dog, so don't get one unless you're really sure you can put in the time.

I need to be walked, played with, and trained, every day... and I still wake my owner up most days at 5am because I'm just so gosh darned full of energy!

He doesn't mind too much though, because I'm great!
