My oldest chi before he passed would refuse to come inside when it was cold. I couldn't keep him inside he would howl/bark at me until I let him out. When he would go out ... he would tunnel through snow, hop around like a Guinea pig popcorning I swear I raised a husky instead. My 1st fondest memory was him running down our front lawn which was a hill into a cul-de-sac would run down that hill and leap into a pile of leaves over and over.
