this is a training issue, rather than a hormone issue. i would work on obedience training with her. rigid boundaries and expectations should help with this issue.
if you feel this is beyond your abilities, please consult a good balanced trainer. you should be able to get a referral from your vet.
agreed – consistency is important during the training process. once she’s used to it and goes in willingly, i’d say feel free to scale back, but for now keep things to a daily practice.
