Aww, sorry to hear that, my call duck did the same thing when the nebibors dog got his mate. Then he tried tomake buddies with the mallard draks, but they are so mean. Eventually he became pals with the two female pekins I had and a banty hen I had. I no longer have any ducks because the same dog killeed them all. Np longer have ducks, but now have the dogs under control.Maybe you can find another call duck,so that he can have a buddy.
