Hi and thanks for your reply.
We had him off the lead last night mainly because there were few people around to distract him. He was very good bar the jogger incident and take your point
We are lucky to have a very busy nature trail nearby which we took him on over the weekend. Lots of mountain bikers, kids, people, dogs, joggers...particularly during nice weather with a good selection of bits that are quiet and less busy so he can explore. He was very good..got a bit over excited when he met another pup and scared him with his enthusiasm *eek*
Will give it a try thanks.
