Not going to get any credit for "common sense" from me. She's had this gelding for 3 YEARS and doesn't know a thing about the basic care of male horses? Has a vet who refuses do a routine cleaning and can't be bothered to find someone else to do it? One would hope for better "sense" than this.
That is kind of a leap.
What one person considers basic care others have never even heard of.
I read the OP as there is a new problem what could be causing it, looking for ideas. Not how can I fix this problem with out putting any effort in and I just can not look bad in the show ring.
The comments about not doing something in the show ring were in response to people saying how to make the issue go away with out actually addressing the actual question.
For the record, I have owned a gelding for a very long time. I have never personally looked for a bean. I have no problem cleaning my gelding's sheath myself but once per year I have the vet give it a thorough cleaning and they take care of the bean issue. Shrug. I guess that makes me a bad horse owner in your eyes since I do not know how to remove a bean myself.
Sorry for just jumping in here but...It sounds like he only does it at shows.
If I were you, I would find local open shows and sign up for every halter/showmanship class you can. Take that opportunity to train your horse to behave at a show, without you worring on placing. I would try to use some kind of vocal command that will make him stop along with backing up or jiggling the chain or whatever you chose. Eventually once you make that vocal command he will get your point without you having to make any movments to screw up your performance.
Yeah...my gelding also likes to embarrass me at shows. Usually when he's waiting around for my class--guess he gets bored. Like the other posters, we just back him up and re-focus him. I would never hit his "area"---he's pretty sensitive temperament-wise and probably would throw a fit.
My question was more "why is he now doing this?" since its new, not "how can I beat his penis into submission when he does this?" Good Grief
I think he took care of this part for you
My first guess would be that even if he doesn't have a bean, something is itchy up there. I use baby oil on my geldings for sheath cleaning, and I've never seen it irritate anyone like Excalibur did. The second guess would be that the area around his sheath opening is itchy. If you scratch right in front of the opening, does he stretch out and moan? I've used Bag Balm there as well as Triple Antibiotic Ointment with good luck. Otherwise, I really like the schooling show approach. Then he can learn that you can discipline him, even at a show, which I think he doesn't get right now.
send some of their smart literate deer who can read road signs up here since ours are just run of the mill dumb ones who get splatted all over creation because they won't stay in the woods
