Shadow is a 4yr old purebred female (no papers though) that we've had since she was 8 weeks. She loves Frisbee, catch, some wrestling, and hanging out/watching TV (not big on plot, just there for the animals). Fairly well socialized, but she growls at our grand-kids (all under 3), so that's our only issue with her. Very affectionate (I'm sure she thinks that I'll soon be dumping the wife so we can start a family) & does well inside or outdoors. Up on her shots & is used to a medium sized backyard (at least 30 x 60). She weighs about 68-70lbs.
