afraid i'm gonna be no help because if you exchange the name saffie for that of barkley, you would then be reading a pretty accurate account of how my dog can be!
barkers is 14 months now and is getting better... but i am very aware that he doesn't yet have anything close to a reliable recall. there has been many an occasion in recent weeks when he has picked up a stick or something and then just wont let any of us near him to put a lead back on. and he has also perfected the infuriating habit of looking up at you when you call him, looking back at whatever he was sniffing, considering the situation for maybe up to a minute, and then just happily going back to whatever he was doing.
i shall read with interest any advice that people give you but i think liver cake may be very much worth trying. roast chicken and cheddar cheese don't work for barkers either!
