My horse is good for awhile after doing join up but then seems to regress over a couple of weeks, especially if the weather is bad and he is not worked with much. I feel like I need to repeat the join up over and over, just to keep his respect. But Monty says you should only have to do join up four or so times. As if the lesson should "stick" forever. What is going on? My horse is a retired race horse and I have heard they are stoics. Maybe he is just not too impressed by anything.
