Oh do be careful with the dog, H! I remember one year we were sharing a lock with another boat. There was a little terrier on the front of the other boat and he fell into the lock as it was filling up. Poor thing didn't survive
19C - I've canalled to Carcasonne. Very nice it was too The Canal du Midi boats have the ideal 'toilet' situation. There's a hole in the bottom of the loo and waste simply drops into the canal. It's probably best not to fall in!
