We're on day 7 of snow and subzero (Celsius) temps and Dexter seems to be acclimating well! back to business as usual on our 4x a day walks unless the temp is colder than about -15c and windy. Then he's a bit hesitant and asking to be picked up. He'll still do his 'thing' but it's a very quick walk.
One thing he's REALLY missing is the other people and dogs he used to see on his walks...as the weather changes, we encounter fewer people so he's absolutely overjoyed when we meet anyone on the street
