I bought my mare in June last year and I only had her a week and she came into season and the misbehaviour started. I put my mare on Oestress and this helped her behaviour and moodiness. I stopped giving her it Sept/Oct and she has been fine. However, I noticed yesterday that she is in season again! In January?! Is this normal? She has been more challenging to work with over the last few weeks. Do you think she needs to be on Oestress all year round? Any advice would be helpful.
