I do have the puppies places in a area that is next to the ducks. I'm hoping they will be used to each other.View attachment 1644184 I slowly introduced my labs to my ducklings. I had ducks in a wire cage to protect from dogs Incase and also so they could be around each other and get use to each other for several days before I let them out together. You may do something like that maybe even vise verse with puppies in kennel and ducks out since they are full grown. Good luck. I attached a picture from when I introduced them.
