Forum rules and no-advertising policy

As a participant on this forum, it is your responsibility to know and follow our rules. Please read this message in its entirety.

Board Rules

1. You’re responsible for what you say.
As outlined in Section 230 of the Communications Decency Act, The Chronicle of the Horse and its affiliates, as well Jelsoft Enterprises Ltd., the developers of vBulletin, are not legally responsible for statements made in the forums.

This is a public forum viewed by a wide spectrum of people, so please be mindful of what you say and who might be reading it—details of personal disputes are likely better handled privately. While posters are legally responsible for their statements, the moderators may in their discretion remove or edit posts that violate these rules. Users have the ability to modify or delete their own messages after posting, but administrators generally will not delete posts, threads or accounts upon request.

Outright inflammatory, vulgar, harassing, malicious or otherwise inappropriate statements and criminal charges unsubstantiated by a reputable news source or legal documentation will not be tolerated and will be dealt with at the discretion of the moderators.

2. Conversations in horse-related forums should be horse-related.
The forums are a wonderful source of information and support for members of the horse community. While it’s understandably tempting to share information or search for input on other topics upon which members might have a similar level of knowledge, members must maintain the focus on horses.

3. Keep conversations productive, on topic and civil.
Discussion and disagreement are inevitable and encouraged; personal insults, diatribes and sniping comments are unproductive and unacceptable. Whether a subject is light-hearted or serious, keep posts focused on the current topic and of general interest to other participants of that thread. Utilize the private message feature or personal email where appropriate to address side topics or personal issues not related to the topic at large.

4. No advertising in the discussion forums.
Posts in the discussion forums directly or indirectly advertising horses, jobs, items or services for sale or wanted will be removed at the discretion of the moderators. Use of the private messaging feature or email addresses obtained through users’ profiles for unsolicited advertising is not permitted.

Company representatives may participate in discussions and answer questions about their products or services, or suggest their products on recent threads if they fulfill the criteria of a query. False "testimonials" provided by company affiliates posing as general consumers are not appropriate, and self-promotion of sales, ad campaigns, etc. through the discussion forums is not allowed.

Paid advertising is available on our classifieds site and through the purchase of banner ads. The tightly monitored Giveaways forum permits free listings of genuinely free horses and items available or wanted (on a limited basis). Items offered for trade are not allowed.

Advertising Policy Specifics
When in doubt of whether something you want to post constitutes advertising, please contact a moderator privately in advance for further clarification. Refer to the following points for general guidelines:

Horses – Only general discussion about the buying, leasing, selling and pricing of horses is permitted. If the post contains, or links to, the type of specific information typically found in a sales or wanted ad, and it’s related to a horse for sale, regardless of who’s selling it, it doesn’t belong in the discussion forums.

Stallions – Board members may ask for suggestions on breeding stallion recommendations. Stallion owners may reply to such queries by suggesting their own stallions, only if their horse fits the specific criteria of the original poster. Excessive promotion of a stallion by its owner or related parties is not permitted and will be addressed at the discretion of the moderators.

Services – Members may use the forums to ask for general recommendations of trainers, barns, shippers, farriers, etc., and other members may answer those requests by suggesting themselves or their company, if their services fulfill the specific criteria of the original post. Members may not solicit other members for business if it is not in response to a direct, genuine query.

Products – While members may ask for general opinions and suggestions on equipment, trailers, trucks, etc., they may not list the specific attributes for which they are in the market, as such posts serve as wanted ads.

Event Announcements – Members may post one notification of an upcoming event that may be of interest to fellow members, if the original poster does not benefit financially from the event. Such threads may not be “bumped” excessively. Premium members may post their own notices in the Event Announcements forum.

Charities/Rescues – Announcements for charitable or fundraising events can only be made for 501(c)(3) tax-exempt organizations. Special exceptions may be made, at the moderators’ discretion and direction, for board-related events or fundraising activities in extraordinary circumstances.

Occasional posts regarding horses available for adoption through IRS-registered horse rescue or placement programs are permitted in the appropriate forums, but these threads may be limited at the discretion of the moderators. Individuals may not advertise or make announcements for horses in need of rescue, placement or adoption unless the horse is available through a recognized rescue or placement agency or government-run entity or the thread fits the criteria for and is located in the Giveaways forum.

5. Do not post copyrighted photographs unless you have purchased that photo and have permission to do so.

6. Respect other members.
As members are often passionate about their beliefs and intentions can easily be misinterpreted in this type of environment, try to explore or resolve the inevitable disagreements that arise in the course of threads calmly and rationally.

If you see a post that you feel violates the rules of the board, please click the “alert” button (exclamation point inside of a triangle) in the bottom left corner of the post, which will alert ONLY the moderators to the post in question. They will then take whatever action, or no action, as deemed appropriate for the situation at their discretion. Do not air grievances regarding other posters or the moderators in the discussion forums.

Please be advised that adding another user to your “Ignore” list via your User Control Panel can be a useful tactic, which blocks posts and private messages by members whose commentary you’d rather avoid reading.

7. We have the right to reproduce statements made in the forums.
The Chronicle of the Horse may copy, quote, link to or otherwise reproduce posts, or portions of posts, in print or online for advertising or editorial purposes, if attributed to their original authors, and by posting in this forum, you hereby grant to The Chronicle of the Horse a perpetual, non-exclusive license under copyright and other rights, to do so.

8. We reserve the right to enforce and amend the rules.
The moderators may delete, edit, move or close any post or thread at any time, or refrain from doing any of the foregoing, in their discretion, and may suspend or revoke a user’s membership privileges at any time to maintain adherence to the rules and the general spirit of the forum. These rules may be amended at any time to address the current needs of the board.

Please see our full Terms of Service and Privacy Policy for more information.

Can't say enough good things about the Herm Sprenger Duo bit

  • Can't say enough good things about the Herm Sprenger Duo bit

    I've owned my duo bit for three years...originally bought for my younger horse, it has sat in my tack drawer for about 2 years now...was just getting ready to sell it on ebay.

    Dentist was out and I told him about my older TB (owned him for about 4 years now)...dry mouth, fussy about contact....he highly suspected the horse may have TMJ. His teeth aren't ready to be done, so he is going to come back in December to work on him. In the meantime, I pulled out my Duo bit, wondering if it would help him.

    At first, I almost put the bit back in the drawer....it looked pretty thick and for a horse with TMJ, I would think it would make things worse. And this horse can be very spooky, would he just run through the bit and I would have little control during one of those bolts away from the chair beside the ring.

    First ride...about 10 minutes into the ride....horse was relaxed, over his back, head almost on the ground, stretching into contact. AND THE SPOOKINESS WAS GONE. When I picked him up, he was soft, round and was happily offering lead changes (he usually gets angry)

    By day four....we had these amazing extensions across the diagnol, a horse who was also willingly collecting up when asked....clean lead changes.

    Today, was just an amazing ride....it was just a stretch day..so I took him in the big arena and let him go....I couldn't believe the push he was giving me...I asked for a little more....OMG, his back loosened up and you could just feel the extension underneath...collected him back a little...asked again, same result.

    The transformation that this bit has made on this old guy has been absolutley amazing. I'm guessing that we had mouth pain, now this bit alleviates it and he isn't afraid of contact any longer. The spookiness is gone, he is no longer having recreational spooks.....he may look at something, but will immediatley listen to me and forget about it.

    Two thumbs up for this bit!!!!! If only I had thought to put it in his mouth three years ago.

    I posted on another thread that the Duo bit is the only bit my stallion is happy in. Cripes...I bought him $500 worth of different bits from Bauchers to KK's trying to get him to settle in his mouth and finally hit on the Duo bit. He has a thick tongue, low palette, and is a sensitive type, and I think that is the reason why he likes it so much. I just wish the full cheek version wasn't over double the cost of the loose ring! That's NUTS!

    I'm happy to hear your horse is still going well in the bit. It is nice when you finally figure out what they like!


    • #3
      Ok, what is TMJ? Also, is the duo legal in dressage? Not that that matters if your horse likes it unless you do want to show him.

      I do think that some horses will not settle except with certain bits. Period.

      Good for you to give it a try ...

        TMJ are the initials for the temporomandibular joint. When used in the context it was used it refers to Temporomandibular Joint Syndrome or Disorder which is the genreal term for any malfunction with that particular joint. Many people have problems with this...I know I do

        I may have to give the duo a try on my old gelding...i think you could use dental floss instead of a bit and he wouldn't notice, but I like to put him in the gentlest thing I can find...

          Where did you see a full cheek version? I've not been able to find one.

              Thanks for the definition.

              Oh, I think I have problems with that disorder too

              I have a really nice snaffle bit collection starting off with my first eggbutt in 1967. Yes, I am old

              I just recently picked up the Herm Sprenger RS D-Ring (it really is a cross between a D-Ring and an eggbutt).

              My pony (Welsh Cob) LOVES it. I can't believe I spent that much on a snaffle! Worth every penny. It feels different to me because I have a pony with a large tongue and a low palette and I pretty much feel his fat tongue in my hands ... however, it works and he works correctly in it.

              He objected to regular snaffles and he really wasn't all that great in the KK or a Stubben French Link.

              Herm Sprenger has always made exceptional bits ... and I go to them for anything out of the ordinary.

                I think it was Dover who had it. Can't remember for sure. It's been a while since I looked.

                I am not 100% sure these bits are legal for showing but I can't see any reason why they would not be. They are smooth plastic and I think that is what the rule book states and why the Happy Mouths are not legal.

                  I am not sure which Happy Mouth bits you are referring to- the regular Happy Mouth snaffles ARE legal- I've shown in the eggbutt at a recognized show and they had bit checks.


                  • #10
                    The ones that are not legal are the happy mouth mullens with the bumps.

                      Just goes to show you the horse picks the bit, not logic, not the rider, not always anatomy either!

                        Are these the same as the old "Nathe" bits? I'd heard that HS purchased the company that made them, or the rights to make them, or something. I have one that's been sitting in my car since forever, waiting to try it on maresy, who has the sensitive mouth/low palate/thick tongue combination very common in Morgans. I do worry about her "running through it" if she spooks.

                          Have to look again, but I am 99.99 percent sure that this bit is legal for dressage competiton...I remember asking before I bought it.

                              This is also a good reference, and regularly updated for rule changes:

                                I beleive the rules show all of the regular, basically simple snaffles that are legal (regular single jointed, french link double jointed, regular mullen mouth, a few of the simple smooth rotating middle bean types that do not have a straight non-flexible hinge type action, and a few others that are basically simple) and then they state that any of those bits can have a plastic mouthpiece or be covered in a plastic as long as it is SMOOTH and follows the original contours of the bit - NO modification of the basic bit and saying you were just covering it with whatever because your horse likes it.

                                From the USEF Rule Book:
                                Dressage Attire and Equipment

                                "... *Any of the above may be made with a rubber, plastic or leather covering, but the bit may not be modified by adding latex or other material. Bits with mouthpieces made of synthetic material are permitted, provided that the contours of the bit conform to the contours of one of the bits pictured above. Flexible rubber or synthetic mouthpieces are permitted ..."

                                  The material is similar to the nathes, but IIRC, not identical. There is now a thinner one available than the original. I use mine at home for both flat and jumping and my horse really likes it. This is the one that I have: http://www.123tack.com/sprenger-loos...hannelid=FROOG

                                    My very sensitive mare went great in her Duo for quite a while after trying every happy mouth out there but I had to switch her to a loose ring snaffle because she was just getting too strong but now she has started throwing fits everytime I pick up the slightest contact so I may try switching her back to the Duo and leave the (in her mind mean metal bit) for jumping.

                                      I have the D ring. It's a nice bit and it is legal, but it's a lot of money to spend for a bit that won't last forever (mine's a chewer). It really bugs me that the D ring is twice the cost of the loose ring, but my pony needs the stability of the D.

                                      I like that it's thin and just flexible enough that she can make it whatever shape she wants, but not floppy like a jointed snaffle. My mare really needs something soft but that doesn't move in her mouth. And, hooray, it comes in 4 3/4.
