Hello. I've just been for a walk at Marbury park in northwich cheshire. As I live in the local village it is a nice place to walk my dog and my nephew. As soon as we got to Marbury park today we went down to see the ducks and there were 3 swans and as usual I put my dog on her lead and held my 3 year old nephews hand for security. One of the swans immediately came out of the water and the other ones stayed in there and started running towards us! This has never happened at all as I've been going down there for years with my dog. My nephew was petrified and we had to hide behind a tree. How can I prevent this from happening again? X
