My Cooper is 5lbs and he loves the snow.....not so much just plain cold weather....but LOVES the snow. If it isnt snowing he will stay out 5-10 minutes in the cold and shiver(sometimes with a coat on sometimes without) but when the snow hits it's like pulling teeth to get him in....he could easily stay out a half hour running around and making angels
without a shiver. I guess each are different and have their preferences. It's up to us to pay attention to them and let them have their fun also.
