Lovely photo's of both you ladies, and it's nice putting faces to the names.
DD, your boy must be ahead of Roo. He only ever piddles once when he goes out, again before going back inside. No more than that at Obedience either. He doesn't appear to be into marking (yet), but he may be a bit slow because he is still with Jarrah and just wants to wrestle her or chase his Cuz ball, while the 4 sheltie boys know she's not far off coming in season so have different ideas altogether than the pup's. Have to watch that lot .
That's really nice that your fur kids are getting a fan club going. Does not surprise me one bit.
