I was trying to think about what factors could have caused Blossom to have breakthrough bleeding or another heat cycle so soon after her June heat. I started to give her an adrenal supplement from a holistic vet containing the following: I understand licorice for one, is estrogenic and for fertility and also for relief in menopause. She started this a week before the bleeding. Previously she was on standard process canine adrenal powder for a few months. On blood testing for resting cortisol her level did go from a 2.0 to 3.8, which was better. She possibly has slowly developing addisons but we don't know yet. Her ACTH was normal but if you read it holistically, the "normal level" she attained post ACTH stimulation was stinking low. So could this be a possibility, I was thinking specifically for licorice.
