Do try to keep up Jonty

I left him way behind in the park this morning, in between the rain, but he was always in sight. If I shouted him he would look to make sure I was still there and then continue sniffing around. Hmmm, thinks, should I start being strict on the 'Come' command if he's starting to ignore me? No, I don't think so, he does come, just in his own time!
When I got far enough away on the small rise he realised I could disappear and came tearing along, as in the photo.
Probably better exercise for him than just wandering along with me so it's not a bad thing.
