It's so hard not to laugh when they're doing that
But you must discourage the biting, and offer a treat every few minutes. Luna's getting better since I read on here to give a tiny treat here and there. I give Luna the Gerber Graduates freeze dried apple bits, she loves them and they dissolve easily, so they don't take long for her to eat. Plus, they're just apple, nothing added
You just have to keep at it. Praise and treat
