Quma is really coming into her own.  Some more work today using climb to initiate sit and down and building up resistance from Quma if I try to move her by lead pressure before the "free" is given.  She has really understood that exercise and I can put some quite serious tension on the lead and she still won't move - she pulls back an equal amount.  Did some nice heel work on leash.  Finished with some tug of war games which she now engages in with hardly any encouragement and then some chasing her favourite ball.  Happy session, happy dog, happy owner.
