Yesterday I noticed my mare was lame in her right foreleg at the trot while lunging her.
I checked her leg and hoof thoroughly for any abnormalities, heat or swelling, but could find nothing. The limp was not obvious at first, but after about six laps at the trot it became really noticeable, so I stopped her right away.
She is 11 years old, with not the best conformation (extremely long back, straight shoulder), and lives out in a tree filled pasture 24/7 with another mare. I got her about two years ago and her previous owner (a good friend of mine) said she had never been lame in all the time she had owned her (7 years). This mare has never worked hard in her life, only being used on trailrides once a month until this spring. Since then she has had the summer completely off, and in November, I started lunging her for about 10 minutes twice a week (no riding).
What I have noticed is that in the last two weeks of lunging, she has been VERY reluctant to go clockwise, to the point of turning with her butt towards me to go back to counter-clockwise (which she never does, she is trained to to face up before turning). I now think this has a lot to do with her being in pain, and I feel horrible because I thought it was bad behavior. However, there was no way I could have known, because she showed no obvious sign of being in pain until yesterday.
I thought maybe she had just taken a funny step yesterday and her leg was sore, so I tried lunging her again today, and at the trot the exact same thing happened.
I have googled alot about lameness since yesterday and the two things I found that could be causing her pain without swelling or heat is arthritis, and navicular. I think arthritis is unlikely because she has never been worked hard in her life, just leisurely rides/ground work. But maybe the amount of work has nothing to do with arthritis? Navicular I do not know much about either, but what I found is that the lameness appears and then goes away. My mare's lameness just started yesterday.
I tried calling the closest vet (which is two and a half hours away) but they are closed for the holidays. To keep her out of pain I will stop lunging her (so she doesn't have to trot). I am hoping I don't have to call the vet because we don't have the time or a working trailer to bring her in, and it would be a HUGE cost to have them come out to my place.
What do you guys think is going on here?
Long distance diagnosis is pretty much a guessing game, but just thinking aloud here: If she doesn't have a history of lameness it's something that happened recently. If she's recently started lunging, and just recently started not liking going in one direction, the lunging is aggravating it even if it isn't the cause. I am not a fan of lunging at any rate, the continuous circular stress doesn't seem great for feet, ankles, or even shoulders. Take a circle proportional to your body size compared to your horses, and run in one direction for three minutes, then switch, for a total of 10 minutes, and then tell me you don't feel the stress in feet or leg muscles. If you want to gently exercise her, unless you are heavy, a gentle stroll in mostly straight directions, not circles, would be good as long as she doesn't seem to be lame in the process. Gentle movement such as loafing in the paddock or walking in hand is better than total stall rest or trotting to the point of lameness. You could try comparing a slow turn(walking in hand) in each direction on soft ground compared to hard, and if she is reluctant to do that in one direction it might indicate a mild laminitis, bruised sole or abcess in the hoof, which is not rare, but hard to see with the naked eye. None of this is very definitive. Presumably you have examined the hoof for any possible nail, sign of heat etc. I'd have her farrier/hoof trimmer take a good look if possible, hopefully she's up to date in that department? Not much more you can do till a vet arrives.
The most common cause of lameness in horses is an absessed hoof. It can take a long time to come out sometimes, but a good farrier will find it and be able to release the pressure. If the horse will stand with the foot in a bucket of warm water with epsom salts in it that will help draw the absess.
Have you checked your horse's foot to see if there is an abscess? If you can't get your vet out a really great farrier might be able to help your girl out.
I agree it sounds like it's in her foot. She could have a stone bruise too if it's not an abscess. It's good that she's out in a field though. She should be a lot tougher than she would be if she was kept in a stall. I'm wondering about the lunging regime though. What's the point? It's not enough to get her fit but might be enough to cause some damage if she's not that strong. It's like going to the gym twice a week for ten minutes. Your not going to get much stronger but you might just pull a muscle or sprain something and make yourself sore.
Dealing with a lot of lame horses over the years - used to rehab them for people - first thought when I read your post was abscess. Soaking in a mild dilution of apple cider vinegar or Epsom salts and movement is the best thing for getting an abscess moved through. When they are lame moving them is not pretty but stalling them and limiting movement with an abscess will only delay the natural process of it breaking out and relieving their pain.
