My Embden gander has been pretty mean to our dogs, pinching them in the behind when they would walk by, it would happen so quick we didn't have time to respond, but I am working very hard now to break his habit and it is working, I am using a long piece of flexible pvc like an arm extension everytime the geese start towards one of the dogs the pole comes out between them, using my voice also at the same time, They are very smart and learn fast. I don't let my dogs and geese out together unless i am with them until we get this down pat, Dogs are your friends, don't make them your enemies.Just stay away from Embden. I have read that this breed is notoriously bad with dogs.
