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.

  • Help! Is this Anhidrosis?

    Hi everyone,

    Before I go into details, my horse IS currently being seen by two vets at our normal clinic, and I've also spoken with another one from another local clinic on this.

    Wednesday evening I went out to the barn to find my horse calling and calling for me, lethargic, and running a high fever of 105.8. Most of the other horses around were sweating, but mine was not. NO heaving, whatsoever.

    We called the vet, and he had us cold hose and give banamine. Within 30 minutes, the fever started coming down, but my horse is still SUPER lethargic and tired. Appetite OK. The vet said this is anhidrosis and that it could take weeks to months for him to be able to regulate his temperature again. He advised me to put him on ONE AC and give him 1 bottle of beer with both AM & PM meals.

    The following morning, Thursday (after he'd spent the night in a cool barn), his fever came back with a vengence again, spiking up to 105.8 before the banamine kicked in (we gave it at 103 & immediately started cold hosing, which also make him shiver violently). 8 hours later, same thing. We seemed ineffective in bringing his temps down with alcohol baths, or ice on the jugular. In my opinion, the only thing helping the fever is the banamine.

    Friday, we had beautifully cool weather (in the 80's only during the day), same thing, plus laying down on the floor, looking almost colicy - so we took him into the vet clinic for COLD fluids and to start the ACTH shot set.

    Saturday - Same recurring fever when the banamine wore off, so I called my vet AGAIN wanting to verify that this really was anhidrosis. My vets said this recurring fever WAS typical, and he wasn't worried. The one I spoke with from the other clinic said she did not think this was anhidrosis, and she would do blood work. I spoke with the second vet at our normal clinic (Who was actually the one on call Saturday), and he said this could possibly also be coming from a virus or infection, so we put him on broad spectrum antibiotics as well as Gastroguard since he's been on the Banamine every 8-12 hours since Wednesday.

    Since having the ACTH shots and starting antibiotics, his fever doesn't seem to go up past 102/103ish. We are still using Banamine/Bute to keep it down. We are also still using the Gastroguard, ONE AC and beer.

    He is still exhuasted looking, and seems depressed at times. Does not want to move past a walk (and he's an ARAB! :-P) Still not sure if he's sweating since it's not been hot enough outside for him to, NOR have we really given him a chance as we're told to keep him as cold as possible.

    I can't find enough information on the internet to make me happy, so I just need to know if this sounds like anihidrosis that any of you all have experienced? My horsey friends who have had horses with anhidrosis have not experienced the recurring high temps in such mild weather as we're having.

    TIA!

    It could be but I am not 100% convinced. It doesn't sound like a typical case to me. If I were guessing I would go with virus. FYI I find most horses respond better to Let M Sweat than One AC. I hope your horse is better soon.

      This does not sound like it in MY experience, there is plenty of heaving,
      to bring the temperature that high I had to lunge in the sun.
      Waterhose would bring down the rapid breathing, I did not have to scrape, put him in front of fan, never any shivering, night time was the worst,
      I had to rinse every hour, never any exhaustion,
      I hope he feels better now.

        I think the key fact that stands out to me is you saying that hosing and alcohol baths do not help and only banamine will bring his fever down. The hosing and the alcohol baths are effectively taking the place of sweating which means if he were sweating he would still have the same problem right?

          Thanks Everyone!

          I appreciate the input. So now, after being on antibiotics for two days, Banamine every 11 - 12 hours, finishing the ACTH shot set, and using beer and One AC, his temp is not increasing dramatically any more.

          Just to restate, it's MY opinion that it's the banamine working to bring the fever down. Mainly because we have been logging like crazy and can see a pattern. My vet has told me that he is not so sure that it's the banamine - and he thinks that the cold hosing and alcohol baths should be working. I just am not seeing it that way. I also have given him banamine w/o cold hosing (basically 'cause I'm tired of seeing him shake violently -- this stopped Friday-ish), and the temp went down still. He has ALWAYS been sensitive to cold water (even in fall, he is the biggest wimp, and will come in sore if he was out in rain under 60 degrees).

          In my logging I found previously the banamine would work for 8 hours, and then the fever would spike quickly and predictibly. As we progressed, the fever started slowly rising after 8. Then slowly rising after 10 hours etc...NOW, he seems to have some MILD temp raising, but not at 8 hours, more like 11ish. Tonight, we waited for 12 hours before giving the banamine to see, and his temp was 100.5 - 100.8 while being outside and grazing. He was still "sore" looking and tired, but wanted to graze and be outside with the other horses.

          He has NO inclination to trot (which is not normally like him - he is a FIT 5 year old Arabian I've been training for dressage and eventing). He normally gallops on his own EVERY day. And if I jog next to him, he ALWAYS picks up a trot. Now, even when the fever is gone, he is still exhausted and looks sore.

          So could his body be getting back to normal after all the treatment for the anhidrosis? Could the antibiotics (2 scoops of Uniprim once/day) be working after only 2 doses already? Or could it be a virus that's just working out?? I have no clue... :-\ But it seems like it's getting better, right??

          Thanks again!

            Fever without panting sounds more like an illness than anhidrosis to me.

            And I believe there is an easy, fairly definitive test for anhidrosis, which could have been done right away if your vet suspected that was the problem was.

            I think I'd be looking for a new vet.

              I am not saying it couldn't be, because my horse is a mild non-sweater and I have not dealt with a severe case before, just mild ones. In my case my horse was often not sweating enough or if indirect sunlight didn't always sweat, more like if he got hot too fast he wouldn't sweat. Also he panted a lot!

              Your horse sounds way more serious regardless of what is wrong. Also in my experience One AC would NOT be working yet, it takes awhile. I don't have any ideas, but I hope you guys get it figured out soon!

                I think if I were in your shoes, I would want to rule out tick-borne illnesses. I know ehrlichiosis/anaplasmosis presents with a very high fever, but I didn't think anhydrosis was also involved.

                I think you are right ... there is something else going on here. Doing some more bloodwork is a good place to start. And if you cannot keep him cool with relatively normal vital signs, it is time to take him to a clinic where he can get more advanced care—not implying you aren't taking good care of him, but you can only do so much in a nonclinical setting.

                The one time I had to deal with anhydrosis was in early July, as a side effect of Tri-Hist. Cold hosing, discontinuing the Tri-Hist and a few pints of Guiness with some beet pulp took care of things and my mare was back to normal within days. But when we found her she was not sweating, had a low fever and a very high respiration rate (over 100).

                Good luck. I hope you figure out what this is soon!

                    I have had experience with two horses who had anhidrosis and another one who literally had his first onset in front of me.
                    For what that's worth, none behaved like this; they all had trouble regulating their temps, but from a clear cause (that is, it was very hot and/or they had been exercising), and they panted like dogs because they were not sweating.

                    Standard ways of cooling them down worked just fine -- you just needed to be more aggressive about it than with a normal horse (one who really had a bad episode we iced his poll and his jugular, and he got acupuncture which really helped).

                    The one who had his first onset was competing on a very hot day. His rider cooled him out as per normal and then I found him (we were trailering together) a few minutes later heating back up, but dry, and panting. Again, he did respond to aggressive cooling. The vet at the show said she'd let him run cross country if his temp came back to normal. I thought this was a terrible idea given the experience I had with other anhydritic horses, but the owner did it anyway.

                    Horse has been anhydritic ever since; now has to be managed very carefully.

                    But in all cases the horses did not need drugs, but cooling, to feel better.

                      I think your horse has an actual fever.
                      She wasn't running away with me, I just couldn't stop her!

                        This is what anhydrosis usually looks like - panting and the fever is secondary to the overheating - it would likely go down if he were cooled without having to give him banamine. Having to give him banamine to bring his temperature down sure sounds like there some internal mechanism going on that's spiking his fever.

                        They can test for anhydrosis by doing a dilute epinephrine skin injection that can tell you clearly whether that's involved - although he could be anhydric secondary to the infection unfortunately.

                          This is what I'm thinking. After going all of yesterday without any signs of fever (although still on bute every 12 hours), this morning (80 + high humidity) he was blowing a little and temp back to 102.8. He was brought in under fans, and his temp immediately went down to 101.8. He seemed happy and ate all his breakfast. This is the first time I've seen the fans work to bring his temp down. After the blood was pulled (and I'm sure the bute kicked in, his temp was back to 100.7 (which it usually seems to stay around when he is feeling OK).

                          The vet came out today to pull blood for cbc and fibrinogen as well as a ketotifen shot. We should have those results tomorrow AM...

                          One vet thinks virus/infection...the other thinks it's still the anhidrosis that is just taking a while to get under control. :-\

                              Viris going around

                              Here in Georgia there is a virus going around that has them running a temp, being lethargic, not eating and having some swelling in the back legs. Your horse's temp seems higher than the ones here have had, but he could have a worse case than I have seen. It lasts about 10 to 14 days.
                              I have a horse with Anhidorsis and have done a lot of research on the subject. Your horse's symptoms don't match with anything I have seen.

                                That one's been going around up here in NY as well. My boy had it a couple of weeks ago and I would have sworn he was having heat stress, but the vet said she was pretty sure it was the virus. He didn't have much of the swelling in the back legs, but some of them have had legs that looked like stove pipes! He was lethargic and didn't want to eat-not even grass. When the "lawnmower" didn't want to eat, I knew something was up!

                                  Blood work came back with the white cell count only slightly high - usually indicative of stress. Fibrinogen test was normal. Nothing really strange other than that he was very slightly anemic.

                                  I also had the vet do the anhidrosis test (epinephrine), but all that tests is his physical ability to sweat (not if his body can control his temperature). We found that he IS able to sweat, so that's a good thing.

                                  Basically he looks like he is feeling back to normal, and his bratty ways are returning! Not sure if he can sweat yet though, since we haven't really given him the chance... I guess just taking it easy and continuing the treatment for anhidrosis...
