I give my mare a daily dose of hormonease . Without it she goes into season and is difficult/dangerous to manage

We have a very good but very sassy mare who can be troublesome in the spring to handle and ride, i put her on Hormonease and it definitely made a difference to her, she was more relaxed and it made a difference to riding her.  She's back on it now and for the summer.

My mare continues to excel using this problem.  We no longer have any mare-ish issues and it is no trouble to feed.  It smells so nice sometimes I want to eat it myself!
