I am a female owner of an australian cattle dog/pit bull male dog who is approximately 2 years old. The dog is extremely bonded to me and in the past has been posessive around men. I recently got married and the dog accepts my new husband, however since the introduction of the "new man" the dog has changed his attitude and is now posessive of me around females. He basicly doesn't like women all of a sudden - except me. Any ideas?
