I, too, am so sorry for your loss, but please do not blame yourself or make the decision not to geld in the future! I think that you made a very responsible decision to geld, a decision that I wish far, far more people in this world had the sense and the courage to make! I own three WONDERFUL geldings and another that I am going to geld in the future. I KNOW that all three of mine (one of which was an aged former breeding stallion) are MUCH, MUCH happier now that they have been gelded (he got to go back in with his mother who he LOVES, LOVES, LOVES).
