I didn't want to go outside last night, but needed to bring up a load of firewood with the tractor, so I took out our young puppy (4 month old cavapom ), and watched him cavort in the snow for the first time. It was probably his fisrt time to run falt out in the yard, so I ran with him.

Not our puppy, but similar;
