I have two (who are sisters) but one is 2 years older and really spoiled and the other is obviously 2 years younger, but spoiled also. For some reason the 4 year old likes to walk and stop frequently to let the wind blow through her hair and to sniff at everything. The younger wants to go-go-GO! I've tried to link them both together so Kiwi (the younger) could take Cleo for the walk and I just have to supervise. Kiwi can outwalk Cleo any day. Probably 2 miles is my guess.
