Another sheltie, definitely. I just dunno what, though I have been thinking about it the past few weeks. Initially I thought when Payton was three, but then I thought maybe I'd stretch it to when he was four... but then I started worrying about Auggie's age being factored in there. If Payton was four, Auggie would be ten. He might still be a total snot but I have worries about his wrists slowing him down, so Payton would need a playmate (Pepper most likely doesn't count unless she evolves into a beautiful crazy butterfly.) once Auggie starts slowing down... so it might be when he's three.
So really it's just going to depend on how Auggie is doing, I think. =/
In an ideal world, there's a particular person I have in mind, and I'd like to breed Payton to one of her bitches and get myself a little blue boy.
OTOH I still wouldn't mind an Auggie nephew, but that may never happen.
Unless I score a high paying job or something, the next dog is IT until Auggie is gone which I'm hoping is at least a decade away. So I have to pick veeeery carefully.
