i believe my collie bitch is showing signs of a false pregnancy, sent her up to my parents for a few days, she tied with their neutered merle collie boy dexter several times over 3days, brought her home and she was still in bloody heat, kept her seperated for another 2days, enduring constant howling from my boy, found him about 6/7days after she started accepting male attention under the dog trailer with her, they were not tied and i believe she was out of season by then, they were unsupervised together for less than 10mins (hoping shes not in pup) sorry seemed to have started waffling
