Along with being extra clingy i also find they tend to get a little nervous of thing that they normally woldnt think twice about. Isis when due in season gets a little nervous of men although there is no barking or cowering she will use avoidance and its not just with strange men she is like it with Doug (our trainer who has trained us since Isis was 10 weeks) and Isis just loves doug. Also i find it can happen upto a month before they actually start thier seasons, poor girlys a slave to thier hormones

(cant wait for Isis to be spayed)
