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.

  • Hoof Gurus ??? re: Coronary band

    So, my clyde X (shown dressage) is having funny issues w/her coronary band. She was barefoot until almost exactly a year ago when a new trainer asked if I would try her in shoes. She was sound without them, but I have to admit, moved even better, she has truly amazing movement, but lengthenings, etc got stronger with the shoes on. Recently, we had some minor lameness issues and did some xrays. The xrays showed an irregular bump and blocking showed some issues in the fetlock (same area as the bump,) but nothing that involved her hooves. BUT, the vet was concerned that her coronary line is not straight-not even close. The shoer (who also works for my vet) was there during the xrays and agreed but didn't seem to have a reason for the change. He was aware of it and had made a few changes to the shoe job with no positive change to the coronary band. The vet asked if I could give my mare some time with nakey feet and see if there was improvement. The shoes were pulled yesterday and the shoer said, "You check that coronary band and tell me if you don't see improvement within 48 hours". Well, I thought that was crazy, 48 hours???? But, this morning (22 hours after the shoes were pulled) her coronary band is almost straight. I suspect by tomorrow it will be.
    Now, this is a very good, very well recommended farrier. I think he does a great job, he shows up without me (so I don't have to take time off work), my horse likes him, he's always been kind with her, BUT WTF???? what causes the coronary band to change shape/direction? BTW it was the same in both front feet. No change in the hinds.
    Don't toy with the dragon, for you are crunchy and good with ketchup!

    Barefoot vs shoes

    I personally prefer barefoot. Horses hooves are like people's feet. None are perfect. They can flex as they need to when they are barefoot. The shoes restrict movement and blood flow. Horses have much healthier feet, includes
    the bones inside, cornet band etc. when they are barefoot and trimmed properly. I would say the shoes were tweaking his feet in a way that was not
    natural for him and so the bump which would be inflammation is my guess.
    See if you can just get the trim that will enable the horse to move better and not use constricting metal shoes.

      I think they call that a "push up" and yes, it can disappear within hours. It makes you realize that the hoof capsule is not some static box. It really moves and changes.

      It sounds like your horse would do well without shoes. Your farrier sounds like a good egg and good farriers are thrilled to have their clients' horses go barefoot. Could you try some front boots if you are needing some extra protection for schooling? I am about to take my dressage horse out of shoes and am going to use some easyboot epics on him.

        The change in coronary band level is usually referred to as "jamming."

        But if your Clyde-X's hooves are anything like my Clyde-X's, then leave the shoes behind.

        Penny mare has amazing rock crushers. I've ridden her over the sharpest gravel, on concrete, on pavement, etc. for miles and her feet just get better. (I do trim myself, tho, so can keep up her between my trimmer's check ups. If I didn't her bars would be huge! )

        Would loff to see some pictures. I have a hoof fetish

          It actually is not the shoes causing the jamming in the coronet band but rather the trim is not right. I'm all for horses going shoeless when possible but I wanted to mention that. Blame the trim in this case and a jammed coronet band is not limited to shod horses.

          When a horse is barefoot, they relieve pressure on the quarters by flaring, chipping and breaking off hoof. It's also a sign of a bad trim but generally they can relieve the jamming themselves if given enough time. In shoes, the shoe prevents the hoof from self correcting so you might be more likely to see problems from that.

          I've seen a coronet band relax in only a few minutes during a trim when a correction was made that corrected an imbalance that was causing distortion of the coronet band.

            Could also have something to do with peripheral hoofwall loading thanks to the shoes. The coronet band is very dynamic: http://www.hoofrehab.com/coronet.htm

              I have seen this also to fix it I have had sucess trimming to correct the jamming then walking the horse around before reapplying the shoes.

              I could be wrong(I am just an apprentice) but from what I have witnessed it can happen on a correct trim if the cycle goes to long.

                what is causing this jamming? is it some part of the internal strucures inside the hoof being pushed upwards or outwards and causing the bulge?

                how does it work?

                  It is the hoof wall itself pushing upwards that causes the jammed coronet band. Think of it for a minute...the hoof wall grows down from the coronet band and changes in the length and balance of the wall cause changes in the coronet band.

                    thanks for your answer Daydream, from the OP and the above, am i right in thinking the bulge lies horizontally and follows along the coronary band?

                    this is caused by the wall being too upright?

                    am i miles off or going in the right direction?

                    sorry, i've never come across this problem before and it's very interesting

                      Not so much as being too much upright but rather too much wall there..more a height issue. It may look level from the bottom to the farrier/trimmer but what the jammed quarters tell you is that you have too long of a wall in that area. The coronet band is so elastic that it will push upwards in an attempt to give the horse a level hoof. A trimmer might "relieve" the quarters by lowering that area slightly...not overtrimming there shortening the wall and allowing the coronary band to relax. You would be surprised how "elastic" that coronet band is and how quickly it can change.

                      I didn't have time to spend a lot of time looking...Here is a pic of a jammed coronet band. Can you see how much upward strain is on that area?

                      I borrowed this pic from Irishcas who posted them on another thread in a shoeing method discussion.

                      This is a normal coronet band. This horse has a clubby LF..it is one that I trim.

                      http://i97.photobucket.com/albums/l2...ss/WBclub1.jpg

                      These coronet bands show lateral imbalance (side to side) as well as jammed quarters on the LF inside of that hoof.

                      Same horse post trim. This is a first trim I did on a client horse. Can you see how different the coronet band appears? You can even see a change in his stance. It's still not perfect but it's a work in process and I did not have a lot of hoof to work with.

                        Just as a side note - this horse is not even enough in his body. He tends to load the dominant right fore more and the left front not enough, hence the clubby left front.

                        The most effective way to get on top of this is for the owner to strengthen the horse's weaker side, so the horse becomes more balanced overall and loads the fronts more evenly.

                        Otherwise , as trimmers , we'll only be fighting an uphill battle with this. Either you'll need to trim this hoof more frequently to get the heels down more or be more agressive when you trim and take the heels down enough, but this can potentially cause some soreness due to decontraction, as those hooves often are contracted as well.

                          I'm assuming this horse is mature. Are you suggesting that through exercise one can fix a club foot?

                              Dune you are assuming that all upright hooves like the one in the photo is a true club foot. Most are not and simply a result of body imbalances - unfortunately this is still a little known fact among horse professionals, vets included because most do not have a very good understanding of the musculo-skeletal system, its portural habits due to side dominance and how this can affect hoof form and wear.

                              Simply observe horses - in pretty much all cases you will find a flatter/wider foot on the dominant front leg and a more upright hoof on the non-dominant side. From what I have observed as a trimmer and massage therapist this is VERY consistent among horses. To verify I also often check the muscle development over the shoulders. The msucles over the dominant shoulder are generally also much more developed than on the non-dominant, weaker side.

                              This also corresponds with what canter lead preferrence the horse has - right sided horses usually prefer the left lead canter, as they like to use the stronger right hind for strike off and balance, while left sided horse prefer the opposite.

                              The more even the front hooves naturally generally are in size (not made by trimming) , the more balanced side to side a horse usually is too.

                                    I don't work with ferals, so I could not tell you - I just know the front hoof shape differences are common in domestic horses to varrying degrees and some are worse than others and respond to correct trimming and body work that evens the bosy out more.

                                    Side dominance influences how the front hooves are loaded. Loading makes the hoof expand . The more it is loaded the more it tends to expand.

                                    Even in humans you can see the developmental difference realted to side dominance - the dominant hand is usually bigger.

                                    If you want to learn more and see supporting photos , look for the upcoming article on side dominance of the musculo-skeletal system and hoof form in the Horse's Hoof and the Natural Horse Magazine

                                    Have not come across one yet. The ones I have seen were simply left too high in the heels, in other words not taken down enough when trimmed, which seems to be a common problem among some trimmers and farriers.

                                        The word "assume" was meant more in a general way, as most people assume this is what a club foot looks like without thinking further about it.

                                        For example, it is widely "assumed" that a club foot is caused by a contracted tendon, yet tendons cannot contract, only muscles can. Tendons can artificially be shortened due to injury, but muscles usually make up/compensate for this, unless it is very severe. At the other end, tendons can overstretch and lose their elasticity, creating joint instability.

                                        If a club foot is caused by a tendon that is naturally too short, the horse would be affected at birth and it would probably be very obvious.

                                        If I pick up a "clubby" looking hoof and I see about 2 inch deep collateral grooves at the back of the heels, it is an indication to me that
                                        1. The horse perhaps is not heel loading enough for some reason, or in other words wants to toe load ( can be due to weakness at the back of the hoof)
                                        2. The horse is not loading this hoof enough due to side dominance
                                        3. the hoof has not been trimmed correctly (taken down enough) during prior trimmings
                                        4. All of the above
                                        All the above are VERY common and can cause the flexor muscles to chronically shorten, pretty much like what happens to women who wear high heels all the time. They chronically shorten their calf muscles - the same principle applies to horse's flexor muscles as well.

                                        True club feet because tendons that are too short are very rare and usually pretty obvious right at birth, unless it happens later in life , thanks to a traumatic injury that shortens the tendon too much.
