My girl is still young (8 months) but I have never had such an easy puppy...ever, and she has high drive. She only has two bad things...she is a puller and she has coprophagia. The pulling we are working on so I am dealing (my arm isn't happy when we walk though) but the poo eating is really really really gross. If it was her own she ate it would be a simple fix, but it is everyone elses. I can't let her play without her finding a nice pile to "clean up" Strangely she has a strong leave it except for this. Anything else her nose goes close to that I don't like...leave it, she comes back to me. Poo...leave it, looks at me, eats it really fast, then comes to me! UGH!
