How can I get this to stop? I tie her up when she does this or not let her out back very much. I take her back inside when she does this. I do tell her no and run around screaming to get her to stop that is what it takes she totally does not listen when she is doing it at all. She will leave it, and drop it for other stuff like poop, cat, are little dogs etc. but not the duck. She is 6 1/2 months old and I don't want her to hurt the duck by it happening when I can't get her to stop before she gets her mouth on it that is what she tries for. Thank you for any help!
