Our mare is really difficult when she is in season - she doesn't want anything to do with people, she gets really spooky, and she is so obsessed with the other horses it's almost impossible to work with her. The mood change only lasts about 2-3 days during which we generally just give her a little extra time off. After that she is back to being her mellow sweet self. Although inconvenient (we have had to cancel riding lessons because of it), it hasn't been too big of an issue but I'm thinking ahead to this summer when my daughter wants to enter a couple of 4-h shows. If Lily is in season for a show I don't feel that she is safe for my 8-year old to ride. I suppose we could just cancel the show at the last minute, but with all of the work and prep that goes into getting ready for a show I really don't want to pull the plug at the last minute due to Lily's "PMS".
I was thinking about trying Mare Magic or Moody Mare to see how it works and was wondering if anyone has had experience with it.
