Talk about a working drive on this Collie X! He's on 4 years old, and not our easiest guy because he's just so "busy"! He's not be terribly willing to be around other dogs, and although he tolerates cats, you can tell he really wants to make them move so he can chase them. Otis is "quirky" for sure ... he's affectionate once he knows you, distant when he doesn't. Super smart, he'd benefit from someone who knows Collies and how to get the best out of them in terms of exercise and having a "job". No to children at this time.
