I'm very aware of the Spaniel's ability and desire to stray off and self reward. With this in mind, I've always tried really hard to keep him close by with lots of rewards for doing so. I always keep him on his toes and change direction. We never do a standard "walk". At the recent gun dog training thing, it was clear that I had the definition of close wrong. I was letting him go too far. Now that I see it, and with him getting a little older (approaching 5 months), I can also see him getting more and more confident. And this straying further and further. He will on occasion completely ignore me regardless of treats. Do you have any tips, methods or advice to keep your Spaniel (or any other dog for that matter) close. Probably unrelated, his lead walking is brilliant now. He will nicely, albeit with a fair amount of Spaniel zig-zagging, with a slack lead. Off lead is a different ball game. I am genuinely getting worried now.
