I am teaching Millie and Roudy to fetch the target. So far, they run out, touch the target and run back for a treat! They will also bite the target, but only at the standstill. I just started 3 weeks ago.
For hugging I just use a carrot till they reach thier sides (without me there) and after 2 weeks of streeaching them I put myself next to their shoulder and make them streach.
Rearing is okay if the horse wont do it over and over I had to stop rodding my gelding to get him to stop its been 2 months and he stopped but senior pictures came and I wanted him to do it.. now I have to wait again.
Treat inside their leg. I use carrrot and bring their heads down till I go between their legs and they will bend back (hopefully) and bow I went through TONS of carrots when doing tricks.
For nodding im going to start by nodding my head and moving his head and give a treat and nod both heads and im hoping when I nod he will after a while.
Smile is harder and I have an idea but I don't know it will work.. so im going to try before adding something but I know a horse that will and its CUTE!
I got gypsy to kiss by holding a treat up by my cheek until she touched it, then she got the treat out of my hand [not near my face !] once she understood the word 'kiss' I started adding more words like 'gypsy kiss' 'can I have a kiss?'
I do not recommend this if your horse bites, snatches, or is pushy about treats, you don't want your face to get bit !
I will try to post some pictures later when I am on my computer. My mare Breezy smiles, says yes and no, gives hugs and kisses, "shakes a paw" does her "downward dog yoga pose" and bows on one knee, and rears. Thankfully she does not try it all the time, only when it is asked of her. We are also in the process of learning to lay down.
I love trick training and my horse has just the right character to enjoy it, too. For now he knows carrying an object (a crop, usually), marching, climbing on different objects with his front legs or all four, lying down on his side, on his chest (this includes also letting me mount him and then rising), sitting, rearing (from ground only), backing up from tail, and I'm working on bowing and hugging. These activities really lighten up the daily groundwork. :)
Other tricks sound neat, too. I'd like to teach him kissing, saying yes and no, and I've got ideas for others building up.
