What a lovely a lovely pair they are!! I think that that snow makes them go crazy,my lot go completly nuts in the snow and be very careful when they are fully grown not to call them when they can get a run at you as you might just become a bowling pin :0 that is what happened to me in Mischa's first snow last winter.
