Well, Rio leaps in of the edge (there are sloped areas but not at this piont), he got a bit close to the edge and since its muddy just slipped in, he can swim and eventually got out, i didnt help him because i know he can swim and can get out at a slope close by.
i want him to like water as much as rio, being dark and long coat it would be great if he will swim.
