Isis has always had skin issues: rain rot, fly bite allergies, scratches, etc. For the most part, these things last a little while, are treated, and then resolve. For the past two months or more, Isis has had lumps under her legs, right where the girth goes. Initially, the lumps did not interfere with the position of the girth. The lumps were slightly in front. However, wearing the girth irritated the lumps.

The lumps are behind Isis’ front legs right in front of the girth. The lumps appear to be only in the skin: I can move the lumps easily around. They feel mostly hard and small. The lumps are not uniform in shape. The one on Isis’ right side is long and tube-shaped, while the ones on the left side are like clustered pearls.

The lumps have gotten worse in the last week (see pictures).

Attempted treatments

I’ve tried a variety of things to deal with these lumps and so far, nothing has worked.

  • Early May: Clipped the hair around the lumps to try and help keep the area cool in case the lumps were related to the increasing heat. Made sure we had fly spray in case the lumps were fly bites. I tried using Sore No More Sports Salve on the lumps to help prevent chafing.
  • Early June: As the weeks passed, the lumps became larger. My vet suggested trying antihistamines, so we started Isis on Histall (which has helped for other conditions). After about a week, the lumps seemed to be softer and slightly smaller but did not go away.
  • Early July: Isis has been off of Histall for about a week and she continues to have more trouble with the lumps. They have gotten larger and are harder again. She is having trouble with the heat so she is also on electrolytes. Her IR has flared up (fat pads above her eyes and on her rump even though she doesn’t look fat), most likely due to lack of exercise. It has been too hot to ride most evenings.

My next step will be to call the vet and see what she recommends. Maybe a biopsy? Maybe this is caused by clogged sweat glands. Who knows?

Just before I started this blog in 2004, Isis had a record year for Bad Things. Okay, not as bad as later years, but up until that time it was Bad. Laminitis, rain rot, sprained tendon, and dew poisoning.

A reader asked a question about Isis’ February 2006 case of belly gunk. In addition to her gelding having the same belly gunk that Isis had, he also has a bad case of scratches or dew poisoning.

Back in the winter of 2002/2003, Isis had a horrible case of dew poisoning. I had not documented what happened with her case on the blog so I am writing about it now. Just in case what I learned can help someone else (like 3horsemom who commented on the Belly Gunk post).

Bad scratches, no donut

Isis’s 2002/2003 case of dew poisoning (a.k.a., scratches), a skin condition that causes crusty scabs, inflammation, and irritation to the horse, was bad enough that she was lame. Dew poisoning most often appears on the horse’s heels or around the pasterns on legs with white socks. In mild cases, the horse has some bumps that are easily treated. In bad cases, the horse may be lame from the painful scabs and have swelling.

Her worst case of dew poisoning started around Thanksgiving of 2002 as a few small bumps behind her fetlocks on her back feet. I treated them by washing her legs with antibacterial soap (so much fun in cold weather), clipping long hair from around the scabs, and picking off the scabs before applying zinc oxide ointment. Over the course of the winter, the dew poisoning got better.

By mid January, the scabs had exploded all over her legs. The scabs went from her hocks to her coronary band on her back white stockings, her front white sock had scabs, and so did her front black. Her back legs were the worse. The scabs were as thick as my thumb in some places. (Other cases of dew poisoning I’ve treated on my mares, the scabs are the size of small beads clumped together.) When the scabs were pulled off, she bled.

Treatment

I finally had the vet out. The treatment she gave me worked for Isis, so I’ll repeat it here:

  • If the horse is in a wet or unsanitary pasture, change the environment if possible. (The quality of the care wasn’t an issue in Isis’ case. We were able to turn her out later so she avoided the dew on the grass.)
  • Do not pull the scabs off. They will fall off as they heal. Pulling scabs off irritates the skin underneath and can actually cause the stuff to spread.
  • Gently wash the area periodically with an antifungal/antibacterial shampoo. You don’t have to wash every day.
  • Use an ointment on the scabs to kill the gunk causing the scabs. Some people use zinc oxide, Monostat (yeast infection treatment for people), or other concoctions (see recipe below).

It took several weeks for the scabs to disappear and for Isis’ legs to heal properly.

Recipe

The goop I used on Isis was made up of:

  • 1 ounce of .5% hydrocortisone cream
  • 1 ounce of Desitine (the kind in the jar, not the tube)
  • .5 ounce of Desinex (athlete’s foot powder)
  • 1 ounce Nitrofuracin ointment

I mixed the ingredients in an old Cool Whip container using a plastic spoon.

Isis ad a lameness exam today. She has been moving stiff since early April. Not enough to where she was lame or off, but just enough that she wasn’t moving right. She was unhappy when I rode. When I ride, she falls in on the right side.

The vet came out today and did a thorough lameness exam as well as x-rays of Isis’ back left and right hocks. Lameness exams take some time: over two hours in this case. She found some soreness on Isis’ front right leg and stiffness in Isis’ back left hock.

The vet did two nerve blocks on Isis’s heel and pastern to make sure the soreness was not caused by something deeper in Isis’ foot. I’m still not sure what caused her soreness there. Maybe it is because she has to compensate for her back left hock hurting?

The vet had a digital x-ray machine: she took the x-rays and then immediately developed them. Pretty spiffy. The x-rays showed that Isis has some arthritis.

The vet is going to make a recommendation for treatment early next week. Possibilities include intramuscular Adequan, IV Legends, or hock injections every six months. Adequan and Legends both are given every week for the first 3-4 weeks (at $50-60/dose) and then once a month after that. The hock injections give HA directly into the hock joints. It’s about $400-500 each time, but it’s only that once. (The bad part is what if something gets into the hock joint when the injections are performed.)

And then there is the whole question about how Isis’ IR might react to these treatments… The vet wants to do more research for treatments and how they might interact with Isis’ IR.

I felt relieved when the vet told me that it was arthritis. It’s not comfortable for Isis but at least it isn’t some strange complication from the IR. It’s just part of my girl getting older.

I quit doing regular updates here when things in real life exploded. Isis’ insulin resistance flared up, my job stress went through the roof, and my back (then knee and hip) all had problems.

During the middle of March, Isis’ crest became more pronounced and she looked like she wasn’t feeling good. It took a few days to really register it, but the subtle symptoms of insulin resistance were back.

My first priorty was to get Isis’ IR under control by investigating her feeding program and upping her exercise. I started by reviewing the factors that had recently changed:

  • Warmer weather so she was using fewer calories
  • Isis was moved to a new barn in mid-February with different hay, but was still on Nutrena Safe Choice, a low-starch pelleted grain.
  • Her exercise program was inconsistent.
  • She was off grass and keped in a dry lot (a good thing).

My posts here have been reduced since Isis has been in NC. I’ve been out to the barn almost every day so I can work with her.

Most of her first week was spent lunging and getting her in shape. Her feet were long, so I had to wait until after her trim to work with her under saddle.

She was trimmed on Wednesday afternoon by the new farrier. He seems really good. He was patient with Isis and willing to explain how and why he trimmed her the way he did.

Thursday morning the vet came out and drew blood for a test for insulin resistance. Once the test results come in, we’ll know where Isis is as far as her metabolic condition. Isis is slightly under weight — a good thing for a horse who has been IR in the past. The vet didn’t think Isis would show that much on the test. The results will provide a good baseline, though.

The goal is to go to a horse show in October. So we’re on our way…

A friend of mine is working on a book and had asked me if there were any situations I’d like to share where my horse had gone above and beyond what might normally be expected.

My initial reaction was ‘Where do I start?’

I have lost almost half of Isis’s available riding time to medical issues. Isis had two boughts with laminitis and recovered fully with little to no rotation and the farrier has said several times that Isis’s feet look perfectly normal. We had a riding accident in 2005 caused by Isis tripping due to thin soles from the laminitis. Grazing muzzle, spiffy shoes, supplements, low starch grain, and chiropractic treatments later: she fully recovered from the laminitis and her IR is carefully managed.

I have always wanted to show Isis. Ever since she was little, I had dreamed about taking her to shows and winning under saddle or over fences. When we were in the middle of dealing with her medical issues, I never though I would get to show. There were days I would have been happy to know that she would be safe to ride.

It’s hard to imagine how far she had come by July 2006. Laminitis behind her, new shoes to help her tender feet, and chiropractic work so her muscular-skeletal system was working well. Her rain rot was under control thanks to the supplements she was on. Finally we were making progress. My vet had cleared Isis for regular work and for some jumping (nothing very high, and not a lot of it over sustained time periods).

My riding instructor and I had discussed whether to take Isis to a show that summer. We both agreed it might be a better idea to let me get some experience on a seasoned show horse and then take Isis to a later show. Besides, the trailer was full so we didn’t have space for Isis. I focused on working my instructor’s horse and didn’t ride Isis that much prior to the show.

The day before we left for the show, my instructor asked if I would like to take Isis. There was space on the trailer. I jumped at the chance to take her to a show just for the experience for both of us. That evening, I went to the barn, pulled her out, worked on her gaits, and jumped her a few times over cavaletti. We also cantered on cue for the first time since our riding accident in 2005.

The next day, my trainer picked us up at the barn and hauled us over to where the rest of the riders were meeting to caravan. My instructor had me pull Isis off the trailer and then tack up for a quick riding lesson. This was the second time Isis had ever been ridden away from home and the first time she had ever seen a ring with a full jump course (the jumps were lowered to 18 inches for us, instead of the 2’6″ for the other riders). She had never seen plastic flowers around jumps. She had never been ridden in a ring with more than one other horse, much less horses she didn’t know.

My instructor was skeptical: last time she had seen Isis and I riding, we had a lot of work we needed to do. She was pleasantly surprised. Not only did the Bay Wonder Mare take the jumps (after some encouragement) and do a course, but she eagerly headed towards the jumps. The other horses didn’t even bother her.

We rode at the show that evening to practice on the jump course. All of the jumps we took at home were cross rails. The jumps in the ring were set at 2 feet and were solid rails with flower boxes. I was nervous. I’d never asked her to jump anything like that. Of course, she picked up on it and shied at one of jumps.

The last time I had done a jump course at a show was on my old Appaloosa gelding when I was in high school. He had a bad habit of shying at a fence: teleporting sideways and leaving me hanging. I remembered that experience and became nervous because I expected her to do the same thing.

We approached the jump several times and each time she shied. I was a nervous wreck. My instructor had me get off of Isis and let one of the other girls ride her. They worked with her again on going over the fence and she did it. I then got back on her and we took the fence. Humiliating to not be able to deal with a situation like that and nerve wracking. My confidence had felt demolished — until we really rode together and took that jump. And took it again and again.

The next morning, Isis and I rode in the warm up ring before our classes. There were probably 20-30 people in that ring riding at different gates, taking jumps left and right. It looked like a swarm of bees trying to find the entrance to a hive. And we rode in that. And survived. Isis was jumpy at first – because I was nervous with all of these kids running around. It was worse than driving on the beltway around DC during rush hour.

My instructor gave me excellent advice: you can’t be nervous if you sing. I picked a silly trotting-speed ditty and sang. I calmed down, Isis calmed down and things improved. The biggest distraction turned out to be not from the other horses in the ring – but from the other horses tied to the trailers parked on the hill. Isis kept whinnying to them. No matter what I did, she was always looking for her buddies.

Because this was my first show in way-too-long, I decided to do something simple. Our classes were in the Walk-Trot division: three over-fence classes with 18” jumps and one under-saddle class. We had 9 people in the division, seven kids on ponies and two 30-something adults.

The biggest surprise of the day? Isis loved it. She headed for the jumps and wanted more. After the first ride, we were both grinning. The second ride, she knew her stuff. We even cantered the course in the the third ride. My instructor was impressed. Isis did pretty well in the equitation class, too. In fact, she kept trying to head for the jumps. We had a few bumps where she pulled against the bit, but that was more my fault than hers.

At the end of the equitation class, Isis and I waited in the line up. I wasn’t expecting anything. I knew we hadn’t done that well, but you know, the fact that we had gotten through it was amazing. I did a double-take when the announcer said our names. And then I grinned and couldn’t stop grinning. (I’m still grinning as I write this.) Isis and I won sixth place in all three of the over fence classes and then took fifth in the under saddle class.

She went above and beyond my expectations and certainly those of my instructor. Isis tackled a set of new situations and obstacles with intelligence and curiosity – and would have done a lot better if her spastic Mom had been calmer initially.

Later I realized that it’s possible that all of the people in that division got ribbons, but you know what? I don’t really care. Those ribbons represent a dream come true after years of dealing with assorted problems and medical issues. To this day, they still hang on her tack room door along with the show number.

Six weeks after this horse show, Isis had colic surgery on August 28, 2006. She fully recovered and we’re now working on low-level dressage lessons. We jump periodically as a reward for a job well done.

I’m on a mailing list for owners of horses who are insulin resistant and/or have Cushings. These can be very serious conditions for horses if left untreated. These metabolic conditions can not be cured, only managed. Isis has insulin resistance and so far we’ve kept her well managed. We have been lucky. She had two cases of laminitis back to back (side effects of the insulin resistance) but neither episode left much damage. In fact this past trim, the farrier said if she didn’t know Isis’ history she would be able to tell that Isis had had laminitis in the past. Amazing.

I feel truly blessed to have Isis still. Last summer when she colicked was the closest I’ve come to losing her. It was devastating to even have to consider preparing to make that kind of decision.

I just read several women’s accounts of how they just had to put their horses down. It was gut wrenching. It is like losing a child or a family member. I can almost imagine what they are going through because I was almost there last year.

To those brave women who have to face this, may your horse find greener pastures and run free. They and the rest of your herd will be waiting for you when you cross over.

The question of whether to breed or not to is especially hard to me. I grew up on a breeding farm. We bred the best Crabbet and Egyptian Arabians (later only straight Egyptians) we could afford and always made sure they found homes. My primary mare, Isis, is a product of the Crabbet/Egyptian breeding. She is the granddaughter of our first Arabian mare. I have had the honor of meeting the majority of her grandparents and even great-grandparents.

I’ve thought about breeding Isis to have her daughter as a replacement. She is an exquisite mare with a lot of jumping and dressage potential. Isis is insulin resistant (see safergrass.org for info on this condition). She is carefully managed now. Prior to her diagnosis, she has had laminitis twice (luckily with little to no rotation) as a result of her body’s inability to properly process fructans. She has also had skin-related issues (rain rot goes systemic, for example) due to immune system problems caused by IR. There is a chance that she could pass this condition on to her foal.

My Mom has a stallion who would cross beautifully with Isis. The foal would have an amazing pedigree and considering the two phenotypes–potentially gorgeous and athletic.

So here is my question… Would you breed a mare with insulin resistance to preserve a much-loved bloodline? How do you weigh the love of the horse and wanting to have her or her daughter around with the potential repercussions on a foal?

(As a side note on a long post After two years of recovery, chiropractic/accupuncture sessions, specialized shoeing, and close work with a trainer, Isis went to her first show July 8, 2006. Four classes, three over fences (18″ walk-trot ;) and one equitation. She pinned 6th in all of the over fences and 5th on the flat out of 9. I was so proud of her. Six weeks later, she colicked from two lipomas (fatty tumors suspended from stalks) that had wrapped around 70% of her small intestines. I do not know if the lipomas were related to the insulin resistance or not. One of her vets (who specializes in IR) said he has seen lipomas frequently in IR horses, but doesn’t have any evidence to show a connection.

Surgery, one week in intensive care, and a lot of careful management…She is (mostly) recovered. I rode her for the first time in the saddle last Friday.)

The vet said that Isis could indeed begin having grain again. She is allowed a cup of grain two to three times per day along with a quarter cup of corn oil morning and evening. I have my doubts whether Isis will actually eat the corn oil. She has objected before to things being in her grain. We will see. The corn oil is a high fat supplement that can help horses with insulin resistance gain weight. With an IR horse, you don’t want to add a lot of grain to their diet. Instead, you look for other ways to increase their calories without increasing the starch or sugars.

After a week on this regimen, she’ll be allowed to have 1 1/2 cups of grain 2-3 times per day with a third of a cup of corn oil twice per day. She can also go back on her regular hoof/coat anti-rainrot supplement (yay!).

I just spoke with the vet. He said Isis is doing about as expected, which is pretty good considering everything her small intestines have been through. She had some issues with electrolyte levels today. That has been corrected and is being monitored. She still doesn’t have any motility in her small intestines and may not for another 24-72 hours. It all depends upon how she starts healing.

She was transferred from the emergency vet to a regular vet today. Well, he’s not just a regular vet, he happens to be a specialist in insulin resistance. Isis is truly in the best possible hands for her case.
