You have a smart dog. My dogs do wonderful with adults but babies have to be kept from them having mini dachshunds with strong prey drives it's just better for dogs and ducklings/chicks to see each other through fencing for a while.It has taken a year for Maddie to understand that these "creatures" are loved by me and therefore "family." Maddie is a "real" dog allowed to have a "brain" and her own thoughts and opinions. I imagine the dogs that harm so much wildlife - waterfowl are dogs not used to being allowed to think who get loose or are stupidly encouraged by their owners to harm & kill or for good reason have long ago lost all respect for their owner's opinions.
