High value treats are really doing the job here - cheese. He's obsessed with cheese. we can walk past sheep, goats, chickens and so long as I put my hand in my pocket then he is completely absorbed with me.
I use the command 'play play' for him to run off and play for a bit then call back with whistle, engage his concentration, talk quietly to him and reward, then off we go again. I will be returning to the sheep-safe course in Malvern again this Summer as he was so young last year, I'd like to see him do it again as a more mature pup/dog.
as for the neighbours...the bottle of Merlot went down well and I'm currently hacking the brambles right back so I can run a fence, not least because the ruddy foxes (pleural!!) are living up there.
