My little doeling, Luna, has a bad habit. She likes to jump up on me. So now I have hoof prints on my pants every time I come back inside. I've tried putting a knee out like I would do it a dog, so she bumps against it and has to land on the ground, but she's a persistent little bugger! She'll catch me right when I turn my attention to someone or something else. Any tips to discourage this behavior before she gets bigger?
