Benji has started jumping up at us whenever we are sitting on the sofa. He doesn't want to get on the sofa, just get our attention. Its becoming a bit of a pain. I don't know whether we should ignore it, push him down with an 'off' command or get down on the floor to play with him. It has started since my in laws have been to stay, partly because we were sitting down more often and partly because they loved to make a big fuss of him but weren't so good at the keeping the boundaries! He doesn't jump up when we are standing and sits to greet etc. Any suggestions gratefully received.
