Obviously good wellies are a must and get a really good wet weather coat, - one of those with a shoulder cape (I know they are not a good look but they do keep you dry).
I find that wearing a good cap keeps it nicely out of my face - I hate wearing hoods, - it makes me feel quite vulnerable because you can't see what's going on around you, or really hear anything properly.
Have plenty of old towels by the doors really for drying paws.
Don't carpet your house, ever.
