I have three Shih Tzu's.....how do I get them used to the ducks. Right now all they do is run like crazy up to the fence and bark like crazy at them. While I was on vacation, they got one of my females and played with her to death...literally! She died. Has anyone had a problem with their dogs being like this and got them over it? I would like my dogs and ducks to coexist nicely. My dogs aren't being mean, they just want to PLAY and PLAY. Any advice?
