Could well be mate. I just find it more than interesting that beddies, and the breeds I mentioned, are a similar size, have similar coats, are good in water, and have great noses.
I know otterhounds have some of those characteristics, but they are much bigger, and 3 times the weight of a beddy, but the other breeds are all very similar in size, coat, colour etc to beddies.
I might be way off the mark, but it's an interesting theory. ?
