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.

Thanks for being a part of the COTH forums!

      I wholeheartedly disagree with this statement. Did you know that anything that is put into a human's body is tested in animals as the step before clinical trials? It's not like there's a big jump here, otherwise we'd make no advancements in medicine.

      A study that found OA in 10 year olds (average age 18.5 years). Secondary to Perthes, which leads to abnormal loading on the joint and subsequent OA.
      I don't feel like going through 83 pages (20 results each page) to find one closer to 4 years of age. I found this result on Page 2.

        I appreciate the replies, but you are sort of making my point for me. We are not in disagreement. Osteoarthritis is a disorder with multiple triggers, and although the microscopic appearance may be the same, the individual's history, genetics, age, weight, other health conditions, etc. play a large role in how the disease progresses and expresses itself. This was my point. Dosing oral products is iffy enough--extrapolating widely between different species and individuals just isn't possible, especially when talking about absorption of oral supplements. The response to a product has more (IMO) to do with the evanescent, relapsing/remitting nature of osteoarthritis SYMPTOMS than with some random supplement being "effective". In other words, grandma's hip is going to hurt worse on some days than on others because that is the nature of arthritic pain. Her using a supplement from the grocery store isn't going to change that fact, although she may swear that when they ran out of the chocolate flavor and she was forced to use the vanilla it made all the difference in the world. (<---actual patient story I was told, not that long ago)

        You may disagree if you like. I'm not saying animal testing has no role or that there are not some similarities. But on the other hand . . . do you know why tylenol is not used in cats? Why grapes should not be eaten by dogs? Chocolate? Why ivermectin cannot be given to certain breeds of dogs? Why benzodiazepines are lousy horse sedatives? Different chemicals and substances have different actions in different species. Fact.

          Scientist types, got a question here.

          We're talking about the efficiency of oral supplements or medication, for that matter.

          We know that HA works as an injectable, as do many of the other anti-arthritis injectables. We also know, don't we, what chemical reactions take place in the digestive system and where and how the active ingredients are taken up by the rest of the body. We could probably test blood to see how much active ingredient actually makes into the blood stream, which would be the equivalent, wouldn't it?, of an injectable's method of working unless it was injected IA.

          Couldn't someone develop a computer model and plug in the variables to see (virtually) if an oral supplement even had a chance of working?

            I guess I just misunderstood your wording, then:

            This is why I thought you were saying in all of these people and animals, it is not the same disease. Which was why I was arguing that it is the same disease. There are many different causes of the disease, but the disease itself is the same.
            If you're arguing about treating the symptoms of OA, then that's a whole different ballgame. Symptoms are far different than pathogenesis.

            But this is true within the same species as well. Peanut butter can be consumed on a daily basis by one human, and kill another. It's the nature of biology and normal variation. We're all different.

            So should we say that what applies to one human can only be broadly applied to another, with a large number of caveats?? No.

            Sure, there are specific examples of where you cannot apply something across species, as you pointed out above, and that is well noted in research. But osteoarthritis is not one of these examples. That was the point I was trying to make.

                The odd peanut butter allergy is not an exception that proves the rule that peanuts are good sources of nutrition for humans. We don't feed cats vegetarian diets because we know CATS IN GENERAL don't thrive without at least some animal products. Trying to point out differences between species, not odd anomalies here. And the rare child with a rare form of joint disease (if the "local paper" is even accurate--not all arthritis is osteoarthritis) is not the exception that proves the rule that osteoarthritis IN HUMANS is generally a time-dependent, degenerative condition that has a lot to do with overuse, age, weight and anatomy. I still maintain that although under the microscope a young racehorse's knee arthritis may look similar to an elderly person's wrist arthritis, it is still not necessarily precisely the same disorder in that different factors had a role. Factors we almost certainly do not yet understand fully.

                A bruise from a hammer blow to the thigh is going to look the same under the microscope as a bruise on the sole of the foot from running barefoot on concrete.

                But I think this is straying far enough from the original topic that it is no longer worth belaboring. Suffice to say that I've been around long enough to never think that one size fits all. And this goes double and triple for the use of medications and/or supplements in one species and expecting it to be the same in others.

                As to computer modeling of drug absorption and distribution--probably it exists. There are actually studies on oral absorption of GAGs in multiple species, as well. But whether a given supplement manufacture is going to bother doing a study to show that their product does what it's supposed to do? Why would they bother? People buy it without any proof at all. Waste of money in their view.

                  as if it were some unprecedented phenomenon, mere conjecture for the sake of argument.

                  I'm not sure what you're arguing here, we use human drugs in horses all the time, use vaccine methodology which is efficacious in human,cats & dogs & only marginal in horses ...

                    Oy. Yes, we use some human drugs on animals. After they've been TESTED FOR SAFETY AND EFFICACY, for the most part. And there are many, many human drugs which are NOT used on horses, cats, dogs, etc. because we know THEY DO NOT WORK THE SAME BETWEEN SPECIES and are UNSAFE or INEFFECTIVE. Humans are not horses are not dogs are not cats are not pigs, although many biological systems work very much the same. Supplements can just be sold with no testing. They are not drugs with evidence behind them. The topic is nutraceutical hyaluronic acid in oral form. It is absorbed and utilized differently between species and this is not a matter of opinion on my part! Jeez.

                    Their DNA may be very close to the same, but would you give your collie a nice big dose of ivermectin while you're deworming your horse or your other dogs? Some nice tylenol for your kitty who just had stitches and seems a little sore? A nice little bit of xanax for your old dog who's afraid of thunderstorms? Of course you wouldn't. Because we know these drugs, while perfectly fine in the proper dose in the proper species, are unsafe or may have unexpected effects for these individuals.

                    One can find 4 year old humans with advanced atherosclerosis and all manner of other diseases. Doesn't remotely mean that a young horse and an old human have the same story to tell when it comes to their bodies and what's happened to them. One-in-a-million freak occurrences are not what I was referring to. Apparently, however, it is imperative to find a single example of something to disagree with every last thing I write. Not atypical, of course.

                        Back to the topic...

                        I did the injectable HA for a 12 year old Hunter with diagnosed arthritic changes in the hocks and OCD for several years. There was an obvious difference. At the suggestion of my vet, I tried the oral HA gels LubriSyn and Hyalauronix and observed similar benefits to the injectable. We were able to increase the time for hock injections from yearly to 16-18 months. We also were careful of footing and watched the workload.

                        During that period, we experimented with switching to less pricey powders with disappointing results-as in they did nothing. Must have tried all of them that were available at the time, had to keep returning to the oral HA. When the horse hit about 17, had to go back to every 12 month hock injections, then every 6 months. Stopped the oral HA and returned to the Legend IV but noted little improvement. Stopped jumping the horse at 20, retired at 21 with unrelated injury.

                        Anecdotal for sure but consistant to what friends experienced, observation within the large show and sales barn I boarded at for many years and what my vets were observing with those specific products on horses of similar age and background with known, diagnosed issues.

                        So, for OP? Whether it works or not depends on the horse and what is actually wrong that is making them uncomfortable. But those few products that worked, the injectable and oral gel HAs, worked right away if they were going to and they did not work on all of them. If you are not seeing any improvement, use up what you have and move on.

                        Cannot see any reason to use it as a preventative, they don't even offer human products as arthritis preventative. So many get it as we age, if something worked to avoid it it would be out there.

                          I have seen the use of the liquid form of HA used to good effect on a stable full of racehorses, many of them claimers, many of them with various and sundry joint issues. All of them were helped. It has to be given daily and squirted in the mouth, not put on the feed. This is the product we used.

                              I was syringing Flex-Force HA into my horse's mouth for a few months. Got tired of the sticky mess and now just squirt it onto his feed. Haven't noticed it being any less effective.

                                I had great results with lubrisyn over the years but it seemed like it was very sensitive to cold and would not be effective if it got cold. I could keep it at a suitable temp but had no control over the various places it was shipped before I got it. I stopped using it for that reason and switched to pentosan or legend.

                                    Pentosan was not available until the very end of the years I managed my aging horse. Anecdotally, it seems effective depending on what's going on with the horse. I would have used it. Horse, now 26 is on nothing except occaisionally Previcoxx
