I'm looking after a dog long term, he is 3 years old and a dear chap, but when walking him he lunges and barks at other dogs and children. A dog trainer has helped, but I am wondering if any Gransnetters have any words of wisdom on overcoming this problem. He is fine off lead and socialises with other dogs well. It is just when he is on lead. I am told he is a reactive dog. Thanks
