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.

Stallion-like behavior in mare - UPDATE and new question post #8

  • Stallion-like behavior in mare - UPDATE and new question post #8

    I am boarding a mare for a friend. 9-yr-old warmblood. This mare displays very strong stallion-like behavior (showing strong interest in my other mares, sounds like a stallion, etc. She has actually tried to mount another mare in the past.)

    I am taking her to the vet to get an ultrasound to check for an ovarian tumor. Does anyone know anything else that might cause a mare to act like a stallion? That is, what else should I make sure my vet checks for?

    This mare has been on regumate in the past due to her behavior. It helps but does not make her completely "normal." She is off regumate at the moment. If we don't find a specific cause of the behavior, she will go back on regumate or a vet recommended alternative.

    She is turned out by herself but shares a fence line with 2 other mares. Has settled down enough that she is okay when everyone is out. But, every time I bring the other mares in or turn them out, new mare calls to them like a stallion and gets agitated. And if one of the other mares is tied in the aisle, new mare calls like a stallion and tries to sniff them. The other mares are not currently in heat but that doesn't seem to matter. It was worse when they were in heat just because they would react to the new mare.

    Read my post about weird heat behavior. Our Mare B (not the one in heat) has always had behavior like you describe. She has always had a difficult temperament which I attributed to her being an orphan, hand raised (not by me), unsocialized foal. The only reason I kept her all these years is that she has been a good babysitter for other horses.

      Sounds like a granulosa cell ovarian tumor that is secreting testosterone. You probably want to pull some blood work too.

          I also agree with Kyrabee. Back in the mid-90's I knew a mare at a barn I worked at who was exhibiting stallion-like behavior. Poor girl would even turn around and bite herself on the flank to "tease" herself and squeal. Turns out she had a cyst on one of her ovaries. Poor girl's hormones were so out of whack, but once they had the cyst removed, she eventually became normal again.

            I wish I had known about the potential ovarian cyst issue back in the day. I leased a massive Canadian sport horse as a teenager. It was like having a stallion and she was very difficult (to anthropomorphize one could say very moody) Very talented, but no vet or trainer suggested looking at her hormones.

              The last mare I owned was spayed due to granulosa cell tumors on her ovaries that were producing testosterone.

              Before the surgery to have the ovaries removed we could only turn her out with geldings because she was mounting all the mares!

              After the surgery she was completely laid back about everything.

              And just so you know, there are 2 options for having the ovaries removed. I know someone who did it and they removed them using incisions in the flank. My mare had it done vaginally and had much less downtime.

              Good luck!!

                Preliminary diagnosis is granulosa theca cell tumor, as suspected. Blood is being sent to UC Davis for confirmation.

                The mare's left ovary is about the size of a softball!

                QUESTION: The mare first displayed stallion-like behavior when she was 5. She is now 9. Is there a chance for her to return to any kind of normal horse behavior since this has been going on so long? I know her hormones should level out after the ovary is removed. But, I am a bit worried about the behavior not necessarily going away since the mare probably barely remembers what it is like to be "normal." She gets very attached to mares.

                  She should go back to normal over time. It may take a few months. Years ago, I had a mare spayed because of painful heats. She did have a solid tumor on one ovary that did not secrete hormones...it just took up space and hurt when she built a follicle. I wasn't interested in breeding and just had them take both. It took her about 3 months to realize that she didn't hurt anymore then she was fine. She still occassionally acted like she was in heat but she was never overbearing with her heat displays. I just chuckled when anybody told me that my mare was in heat.

                    Hello fellow boisean!

                    As a side note, spayed mares still produce the hormones to come into heat and can actually exhibit worse and longer "in heat" behavior than before. It can be quite annoying, but the heat cycle is at least not painful. Regumate can be used to keep the spayed mare out of heat (hormonally).
