He does run, Hazel, but generally not from the shelties. More like at them.
Barkingdog, he's a bit over 10 months now, he might be finished growing upwards now and start filling out. His breeder has a couple of lovely male pups for sale, a red and a lovely blue pup. Good thing I can't let myself be tempted, we've had so much fun with Roo but he'll have to do for the next 14+ years I think.
