Wet Dogs in Caravans

Just wondered if this would be useful to anyone else; one of my dogs loves water so spends much of our holidays looking like this

Not great when we only have a very small caravan. I saw something called a wet dog mat that is designed for incontinent dogs but also suggested for dogs that do hydrotherapy or just like getting wet. It absorbs water then doesn't let it out the other side (I'm not explaining it very well!) but it was a life saver last week and kept my car seats and then the caravan seats clean and dry when Douglas was wet after swimming. In case anyone else is interested - http://www.jacobsden.co.uk/the-wet-dog-mat.html
