Thanks for the ideas,
I don't have water outside - except a cold outside tap - I don't have the strength to hold them and they'd scream the neighbourhood down
I use vetbed in their beds, as you say, easy washed and dried, but the conservatory is 4 meters long - a big double sheet and towels is actually easier than vet bed for that.
Just wish I could do something outside to stop them getting muddy - they have to have baths for dog shows anyway - but that's inside.
Maybe I just have to grin and bear it like everyone else till spring and summer arrive
