What has worked for your horses with heaves when you have to stall at an event? I know every horse will be different but I am curious what has worked for others.
Some of you may remember my past threads but I felt a new thread was appropriate since I have a more specific question, and I have learned some things about what seems to be working for my horse, over the course of the year.
Mare is 8 years old this year. We primarily barrel race. Last year is when we started having trouble. I feel that I have kept her REALLY well managed this year. I am lucky that I have a lot of acerage so she is outside 24/7 on pasture grass. (not in a dusty stall and not in a dusty dry lot) We had lots of rain this year which I believe was also helpful that it wasn’t dry and dusty. We are still dealing with wildfire smoke from time to time but not as bad as last year. We typically don’t have a lot of humidity; if we do, it doesn’t usually last too long.
Last weekend was the first time in a long time I have done a weekend event where I stalled her. They were outdoor stalls. The first day she was fine. About halfway through the second day I noticed her breathing was elevated and she seemed to be having a mild heaves attack (I say mild b/c she was still eating and drinking but she certainly was not right). I always travel with my meds so per my vet, I gave her 10 mL of IM dexamethasone as well as nebulized dex/albuterol in her Flexineb. I also took her out of her stall and tied her to my trailer in the campsite, in the shade, and cold hosed her off. I’ve learned over the summer that those things seem to help if she seems to have elevated breaths per minute (cold hosing and getting her some shade). Within a few hours, she seemed much better. I did end up scratching my barrel racing run that evening, which really sucked, but it’s not worth my horse’s long term health.
The next morning, I got up real early and got her out of her stall again, and gave her 5 mL of IM dex and nebulized dex/albuterol/ipratropium. We didn’t have a run until much later in the day and she seemed fine so I did choose to run her that day. She did fine, and she’s been fine all week since we have been home.
But we have a few more weekends coming up for 3-day events where she’s going to be stalled again and I want to prevent a potential heaves attack. I have the approval of my vet to give her IM dex “preventatively” when I have to stall her, and we also switched up her nebulizing medication this week to RRVP (budesonide, etc). I have been doing either albuterol or ipratroprium during the week, but not on the weekends and/or before barrel runs. I have been avoiding nebulizing dex unless I absolutely have to.
-Tried the Aservo inhaler for her earlier in the year but did not seem to work for her. She coughed more after her 10-day treatment than she had before it.
-She is nebulized Alpha2EQ about every 3-4 weeks. I do feel like that makes a difference.
-She is also given kenalog injections, and we currently do every 6 weeks.
-She has been on allergy shots for about 8 months now.
-She is fed a very clean diet for any supplements/feed as she is allergic to quite a few ingredients (including soy and flax). She gets Purina Outlast, Hygain Zero, and Standlee alfalfa pellets, long with 24/7 grazing in the pasture. She is a picky eater but she does like Race Today which I give her.
-She makes her barrel runs on LASIX because she is a bleeder. We just recently had a clean BAL at the vet to confirm that my dosage and timing is appropriate for her.
-During the warm months, she only gets hay when we travel and it’s good square bales.
-I have rarely needed to give her IM dex this year and I only give it to her when I absolutely have to, in order to avoid steroids as much as possible. Thankfully she is not the body type to founder, but the risk is still there.
It seems to me for her that a major trigger is the mold under the grass in the spring when it starts to warm up the first time. She had a heaves episode in April 2024 as well as April 2023 (which was her first episode that started this whole thing) and both times was when it got warm for the first time after winter. She is on a round bale with a hay net during the winter but she actually did well this winter and didn’t have any trouble when it started to warm up. I’m not opposed to figuring out how I can switch only her to square bales this winter (and leaving everyone else on the round bale) but I’m also not convinced that the round has anything to do with it. Seems to me I should have had more trouble with her this winter if that was the case but that’s one of the things I’ll still have to figure out for her if that’s a true trigger or not.
And obviously I have learned that a new trigger is DUST from being stalled at multi-day events, with the dust from the stall and the dust from everything else (alleys, warm up pen, outdoor arena, etc).
Some places allow me to set up my own pen at my trailer and I can obviously park as far away from the dust as possible. Other places do NOT allow you to set up your own pen and some don’t let you tie to your trailer in some areas. So some events I will be limited on what special modifications I can try to make for her.
Anyway, so as stated in the beginning, my question is what has worked for others to try to prevent a heaves episode when you have to stall at an event? I normally make it a point to just haul for the day but you just can’t do that when you are driving 4+ hours to a 2 or 3 day event.
