My puppy was getting way too excited for food. Constant zoomies, barking, jumping, etc. I taught her to sit before she gets her food and now she will wait patiently for her food. However, she's stuck at that step. I can't get her to know it's okay to eat now. She just waits patiently in front of her food and wagging her tail. I pet her, tell her to eat, bring the food up to her mouth but nothing. If I step away, she just follows me or she will sit next to her food and stare at me. She will eventually eat later, usually when I step out of the room. I've stopped telling her to sit before eating, but she still sits patiently now. Any tips?
