Every ride is a training ride and it is often easier to teach horses bad habits then good ones.
That is so true!! I have had Biscuit 13 months and every ride with him has been a training ride. He is/was sweet, gentle and willing but was also allowed to just follow mindlessly on the trails with a totally inexperienced (read never rode a horse in their life person) on his back so he just tuned everything out.
Every ride has been to reinforce his good points and work on those that aren't good or could be better. Leg aids on and hands gentle but firmly on the reins has helped. Also me learning better aids has helped IMMENSELY because Biscuit wasn't the only one that needed training!!
