So I took him down to the Common to practice recall today, and he actually did pretty well, the little hooligan. Even managed a little bit of loose lead walking on the way down there (he had to, or I'd have been on my arse, it's that icy today).
Then I looked like a complete lunatic for the first 20 minutes or so as every time he scampered too far ahead, I doubled back or went off in a different direction. After that he was pretty good at checking in and keeping me in sight. I wasn't planning to use the whistle today as I didn't want him to be able to ignore it, but at one point he went round a corner and got distracted by some other dogs, so I did call him back - he couldn't see me but turned immediately and ran back to where he thought I was. So overall a big success. Obviously mentally challenging for him too as he's completely exhausted now.
I am not going to get complacent again though, I'm going to keep looking like a maniac and doubling back on him for a few weeks I think.
I'm so relieved that it looks like I intervened in time. I had visions of him turning into his mother, who was notorious for escaping the house and disappearing off for hours at time.
I'd like to take him for a walk in the woods, but not sure I'd risk it without him physically secured to me (can you get people harnesses as well as dog ones?)
Today's very good boy:
