Ollie and the Jetty

Great day for Ollie today, he finally walked right to the end of the jetty, something he has been trying to do for a few weeks !
But at the end of the jetty is a ramp which leads down to the floating pontoon. He eventually put two feet onto the ramp but would go no further. It would be interesting to know what is going through his mind; he is desperate to do it, is clearly frustrated with himself, and won't leave, unless his lead is on. He has a few months to conquor his nerves otherwise he won't be coming on boat trips with us in the spring/summer !
