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.

  • Spinoff--vision and spooking

    I had a horse with an old injury in one eye that left him with a small, very small blind spot. He'd always spook if something unusual came up on that side--shadows, ditches, funny lines in the dirt, you name it.

    General Chamberlin in Training Hunters, Jumpers, and Hacks made a big point of checking vision when looking at horses to buy. He says that horses may have blind eyes that simply do not show any signs.

    He wants to see the horse first in its stall.
    While in the stall if visibility is good, in addition to studying the expression of the eyes, a minute examination should be made to be sure that no cloudiness impairs the vision. Also, while standing a little to the rear of the horse's head, move a hand quickly upward, close to and past the eye, carefully noticing whether it blinks as it should. (Page 8)
    Next the horse should be led outside the stable. Closely study the eyes again just as he comes into the bright daylight. An eye may be totally blind from a paralyzed retina and yet appear clear and normal. Many a horseman has failed to find this defect until weeks after a purchase. Only by noting the contraction which the light causes in the pupil of a good eye, and the blinking which occurs when a hand is passed close to it, can one be certain that this type of blindness does not exist.
    Is this really as big a problem as he seems to indicate? Have any of y'all ever had a horse with a paralyzed retina? Heard of any? It's not something that I'd even think about. How much do PPE's focus on things like vision? Do many of you do ongoing vision checks?

    I think part of the problem is that it is very hard to tell how well horses see, without vision tests etc. Blind isn't that hard to identify, but limited vision seems hard to diagnose, since they don't have the eye chart etc.


    I owned a horse for 5 yrs who had a detached retina.

    At the PPE (age 6) vet examined in a dark room, said it was a small cataract, that horses can almost always see around them, shouldn't be a concern, they tend not to progress quickly and he will probably be very old before much vision impact. He was just off the track, so no performance record.

    Later on, my vet felt it was most likely a misdiagnosis at the time, that he had always had a detached retina rather than a cataract, but who knows . . .

    He was spooky, but not abnormally so--I've owned much worse. (Trainer said he was the most nervous horse he had ever owned at the track, so it may have been a factor there too).

    I never noticed anything to make me think he saw better on one side or the other--he didn't carry his head off-center or spook one way more than another.

    Initially he was very afraid of water--it took a long time before he would just go in and not put in a first stop. He was also a careful jumper, not necessarily in a bad way (gorgeous form, never rails), but I wasn't sure how bold he was going to be.

    Aside from the water issue he had a pretty normal early career at N/T. Jumped around half a dozen prelims, then had a relatively minor mishap at one (@ Marlborough--downhill 2-stride with the 1st element on the crest of the hill--he jumped the 1st, then sort of slid into/chested the 2nd). Retired on course, but he was never the same--just didn't want to do it. Dropped him back to novice starter trials and couldn't get him around. He'd jump a fence or two and then quit.

    So, did some jumpers with him, he was quite successful in the high AA and modified A/O, and it was at my selling-as-a-jumper PPE that they identified the detached retina, felt he was virtually blind in the left eye.

    Thinking back, the hints were there. He was spooky, had a water issue, gave up on xc after a mistake (perhaps he didn't see the fence in time and that was what scared him). There was also a more recent weird sj stop that I had attributed to me getting too greedy and putting to much L to R angle on the fence, but that was probably vision too.

    Hindsight being 20/20, I should have known that Chester's wasn't, but at the time nothing seemed too out of the ordinary. Just an OTTB who was a bit spooky and chicken and would rather stay in the ring. Now I feel really guilty for all I put him through.

      I honestly think I'd rather have a horse with one completely blind eye than one with spotty vision in one eye. If you know the horse has a blind eye, you can compensate and so can the horse.

      But if the vision is spotty, learning to compensate is almost impossible because things go in and out of the blind spot so quickly.

      BTW, I knew D had spotty vision when I bought him, and he never threw a dangerous spook under me except once, and that was when we were on asphalt.

        One of my horses had a VERY large problem with his eyes last summer that has left him with a blind spot or two in one eye. So far no spooking but his soundness has been limited too so I am not sure how it will work out under saddle. He is sounder now.

        My 27 yr old is developing cataracts. He does now spook occasionally. He almost NEVER did before.

        One thing I do know after more than 20 years of working with Linda Tellington-Jones and doing TTouch on horses is that TENSION in the poll and head area can negatively affect VISION!! And once you release that tension, they will spook less because they can see better. People who have bad headaches know this. I have had sinus issues for years and that has definitely affected my vision. I just had sinus surgery last week so it will be interesting to "see" how things change!

        Any eye check in a PPE would be VERY important.

        But one also has to consider the shape of the horse's head and the placement of the eyes because this is VERY important too and almost NO ONE talks about this. LTJ is the only one I have ever heard consider this.

        Wide set eyes give the horse great vision to the side or rear but gives them. potentially, a larger blind spot in front. Eyes place closer to the front in a narrow head will limit vision to the rear. Offset eyes are probably most troublesome because the view is from different angles. I met a horse years ago that was very difficult who had one small eye and one normal sized eyes.

        One of my horses had a very crooked looking face especially when he was younger. Nothing matched or lined up evenly including his eyes. He was VERY difficult but has gotten better and better over the years. Interestingly his face has become much more balanced looking and even.

          I had a horse who had a very specific spook and I think it must have been vision related although nothing was ever diagnosed. Always on his right side, and one day hacking I realized that as we approached a scary object on the right he moved his head around- up and down and then finally way around to the right so his left eye could see it - I could tell he was trying to get his head in a spot that allowed him to see it. If I moved his head (nevermind leg yeilding and obedience, just his head, this was an experiment) wayy to the left so he could see it only out of the back part of his right eye, he did not spook. Nor did he spook once his forehead had passed the object, so something didn't work in the front part of his vision on the right side. Once I understood that, I could make our lives easier by positioning him in ways that he wasn't seeing poorly - except in the dressage ring where the flowers and letters came up anyway.

          He evented at preliminary, so he functioned but he often blew in dressage about the flowers.

            Good point!

            I read a post elsewhere from a woman who's mare kept spooking randomly - a veterinary student used the mare as a guinea pig to practice doing eye exams on horses and found a dark "floater" in the mare's eye - which is what she'd been spooking at...

              I know my current youngster had a routine vision check in his PPE, that was 2+ years ago. Since he does get a bit spooky I had his eyes stained and checked in most recent annual. I really didn't think his spookiness was vision related, but was happy to spend a few dollars to rule it out.

                Having owned one spooky horse with wide-set eyes and ridden or known a few more I agree with this. I gave up jumping the one I owned and he was much happier as a dressage horse.

                  Yup.. imported a super talented horse once who turned out to be super spooky and nappy. Eventually turned out that he had cataracts. Three vets missed them.
                  Now, whenever I hear of a super nappy horse I always consider it as a possibility and would certainly always push to have the eyes VERY carefully checked..

                    One of the first horses I ever rode had super spotty vision... and he packed me around western games and barrels without a spook. The owners didn't tell me until I'd moved on and up, since they weren't sure how my little 6yo self would feel about that. He took a little more guidance than the others I rode but he was a golden little thing.

                    I've ridden lots with bad eyes that were wonderful, and lots with good eyes that weren't.

                    I think a lot comes down to how the horse handles it, and perhaps how it came about as well. (I.e., if the horse suddenly had poor vision or loss of sight from an injury and had no time to adapt to it, as opposed to a horse who gradually lost vision due to age or a degenerative condition).

                    I've also got to agree about the eye width thing, at least for the most part. My guys both have narrow faces (eyes set appropriately to their face size, but their faces are just very narrow) and they're both brave and unflappable. So are most of the other more narrow-set horses I know.
