I want to wish you all the luck with your Jolly. I am sure the two of you will do just fine.Please keep us posted? As for a horse nuzzling you,putting his/her head on your shoulder ect. I don't see that as a sign of the horse being pushy.I train horses all the ti me and and had a horse lower his head and stick his nose under my arm...to me that showed trust.Anyway,good luck.
