Your picture just warms my heart. We had 2 Choc Labs and Finnegan (who passed away 3 years ago at 14 1/2) loved to make snow angels. He supplied us with years of entertainment with his love of the snow.
When we hike in the mountains in the early spring, Michelangelo [Jello for short] will literally wallow in any of the snow patches he can find at higher elevations. Watching the steam rise off his body cracks me up!
