The first time our previous dog, a long haired Maltese terrier from Pretoria, encountered snow outside our front door in Cumbria, she charged around in it for a couple minutes then stopped, literally frozen to the spot. Had to be picked up and the underside de-iced.
Remarkably for a collie x labrit he took 4 steps, and turned round and charged back indoors. And refuses to go back out. It’s hard to believe but maybe snow is new for him.
Bedtime pee is going to be a battle.
It is winter! Here in south Manche, we briefly had thunder snow, intense enough to trip the power twice.
Admittedly not very deep. She and Bertie thought it was the most wonderful thing ever. 
My Shiba Inu used to adore any snow we ever got which in his life was only once that actually covered the ground. It was in his breed coming from the northern island of Japan and being a primitive race so it obviously stirred his genes. Getting him back indoors from the garden was a major operation when he discovered this white stuff. I miss him so much but we had 13.5 years together from birth.
My cats were very snooty, would beg to be let out and then spend ten mins sticking a paw out and testing the white stuff meanwhile letting the heat out and then decide going back to bed was a better plan. The litter trays got a good bashing over those few days from four cats.
Son just phoned to check in on me as he does every day and said they had over half a metre of snow fall since yesterday evening up at Les Angles so the kids were making the most of it sledging and the adults skiing. He said the wind was also very rough up there as it is here still at present but blue skies and sunshine all round.
Very pleased for you, nice to have family within easy each.
