We have a nice looking TWH yearling that decided to develop a pushy attitude, etc. We gelded him last month and to date, his attitude has improved 100%. Taking him to get some basic training this month. He has also been ridden about 30 min in a round pen since gelding with no problem. Amazing what that little surgical operation will do to a male! (I have even met some human males where that would be a viable solution to their problems...lol).
