Hazel, she is sometimes overwhelmed by him, especially if it it hot and all he wants to do is wrestle. Scares me to think how I'd manage him if I'm away for a show weekend. Reckon I'd need to take a puppy pen for twice daily play, but then he has no-one to play with.
Barkingdog, I always gave the shelties bottles with a few stones in them, they love the noise they make. Roo doesn't, so might have to remove the stones and try him again.
DD, how are your babies going? Are they rough pups like this guy? I sincerely hope not.
