We have a 5 y/o lab, 2 pekin girls and 1 mallard drake that are 1 y/o. The drake is CONSTANTLY chasing the dog. Just started doing it this spring. For the most part the dog has fun but I know she gets tired of never being able to lay in the sun in peace. Most of the time I put the drake in time out in the fenced area. The dog has never been mean to the drake to provoke the attacks. The drake will litterally seek out the dog and chase her. Anyone else had this problem?
