I have a 2yr old spayed female who suddenly became vicious to my other female after living peacefully for the first 8 months living together. I was told that it was due to Halle (the younger one) maturing from puppyhood to an adult. The attacks started when Halle was about 8 1/2 months old. She is not spayed and just started her 1st heat cycle last week. Lexie (the 2year old) will still attack Halle given the opportunity, I have no doubt, so we've been keeping them separate for the past 2 months or so & will continue to do so. I believe it may be partly the "female" thing and also partly a jealousy issue about time/attention from me. |
