Thanks everyone for your replies!

Actually Tom was prancing around as if it was the height of summer - he didn't seem to notice any difference in the conditions.

Candy though was doing that little flicky-shaky-paw dance as she walked through the snow..... Not her cup of tea at all.

Actually they were both back inside LONG before me while I pranced around for a bit more. Much more rain since so its all gone now. Hopefully you have the same result in Belgium so as not to ruin your plans!
