I don't do any heelwork training on lead so from the outset I probably have to do more work that those who do all their training on lead & get through tons of cooked chicken(part of the dogs diet)in the process. I do a little & often & alway finish on a good note
I also teach dogs to play(our GSD arrived at 8 months unable to play as no one had ever played with her & now to get her attention I just touch or mention a toy)if they don't know how to, if the dog isn't interested in an ordinary tuugy maybe rubbing something he/she does like on it I like the ones that are about thumb thickness,
Perhaps going back to basics but using a different method for heelwork & doing training rounds in the higher class might help, it's a same when the set exercises are done well to be let down by heelwork & of course lots & lots of play in between the short bursts of heelwork training to keep him thinking what is coming next.
As a judge I have no problem with training rounds after all where else can you train for the ring but actually in it at a show ?
