Thanks guys, brilliant advice. Worked on recall this morning, making sure he came all the wayback to me rather than a half hearted attempt where I had to catch up. Will try all that you suggested and yes I was considering the BARF approach in conjunction with our little trips. The good dog man in our area is currently rather ill so really appreciate help over the net. Think if he could talk it would be a sad tale- he did have a lovely owner but she had JR's and other dogs too and he really likes a one to one. So glad that he's starting to get his mojo back!
Heres the best pic I could find, no
