I've taught my mare some tricks too! When it's too hot or too cold to ride, I need to give her a job and keep her mind occupied
She picked up all her tricks super fast- they each took less than a week for her to learn
Liz does kisses, high fives (touches her nose to my hand), hugs to each side and down (nose to ground).
She loves doing her tricks! For hugs, she hugs then straightens out and then "comes back" for a second hug. I also make her do a few tricks in a row for a reward. For example, she'll have to go down, kiss, high five, kiss and down for one treat. For a while, she would only do tricks with a hand cue. Now, she'll do them all with just a verbal command.
I'm not sure what to teach Lizzie next, either! She's not mouthy and doesn't paw, so I don't want to encourage either of those behaviors. I don't want to teach her bow because she's old and arthritic and I think it would be too hard on her physically. I think I'll teach her yes and no this summer
