Who's a good boyyyy?! Ryu is! Ryu is a young pup who's learning his P's and Q's and taking his training seriously. He's already mastered sit, is doing great with down, and he's working on wait (because manners), plus place, stay, and watch. He's crazy smart-just 10 minutes a day and he's locked in and loving his "homework." If you've been looking for a fun, trainable buddy who actually enjoys learning, Ryu might be your guy.
