I've Used Ivermectin

10/11/2021

For my horses, and only for my horses. The way things are going right now, I might not be using it for a while.

On Saturday, I stopped by my local feed store for some beet pulp and rice bran. Hanging on the door was a sign saying they had dewormer. When I walked up to the counter, I laughed about the sign and asked what that was all about. Apparently, there is now an ivermectin shortage. First it was toilet paper, then it was computer chips for cars, and now it is dewormers.

When I asked why, the clerk said she didn't know, but the gal who runs the place can't get it back in stock. None of her suppliers have any. We both whipped out our phones and did some searching. We both found article after article reporting the same thing: feed stories around the country are now keeping dewormers behind the counter, and in some cases, requiring proof of horse ownership before they'll sell a tube.

I shook my head in bafflement. So did she. The media would like me to believe that every looney tune across the country has decided to hoard ivermectin to use as an antidote against COVID. Other media would like me to believe that the government has forced manufacturers to reduce the production of ivermectin so that the medical field can't prescribe it to combat COVID. I am certain that there is a reasonable explanation for the "shortage," but I don't know what it is.

I would appreciate it if you would all start reporting facts, not fear.

Based on my vet's recommendation, I deworm with ivermectin twice a year; once in the spring and once in the fall. I almost always have fecal tests done first, but I've been a bit lazy about that this year. My horses always have a zero eggs per gram result, but I use the dewormer anyway. There is a long explanation why, again, based on my vet's recommendation, but that's not today's topic.

I generally deworm in November after the first few cold days of the fall, not that it actually gets "cold" here. When I buy my ivermectin boxes, I usually get them in groups of three or four. Once I made it home from the feed store, I checked my medical drawer to see if I still had a few boxes left. I didn't, but I did find a brand new bottle of prednisolone, a box of Prascend, and some whitening shampoo. I like to buy things in advance.

Price gouging?

If I am ordering from Dover or another online tack shop, I'll often throw in a few tubes to meet the free shipping requirement or to just round out my order. With nothing else to buy, I decided to hit up Amazon first. The price of ivermectin there has shot up several hundred percent. The last time I ordered ivermectin from Amazon, I paid under $12.00 for 3 tubes - about $3.50 a tube. The price is now closer to $18 a tube.

Before paying such a ridiculous price, I took a peek at the Riding Warehouse, my go-to for most everything equine related. Fortunately, the fine folks over there have only raised their price a tiny bit, if at all. I was able to buy four tubes for under $34 - $7.95 a tube. More expensive than I feel is normal, but it was an acceptable price.

I don't understand the world right now, but it's making me very angry.

Speedy's Junk

7/16/2021

It has been a month since I've done an update on Speedy's junk, so here goes: On June 11th, Dr. Tolley wrapped Speedy's man parts in a sock in an effort to prevent flies from depositing habronema larvae in Speedy's urethra. You can read about it and see pictures here. That sock was the second attempt to thwart the flies. For the second go-round, Dr. Tolley also gave me a steroidal solution to swab over Speedy's urethra several times a day. That was five weeks ago today.

"The Sock"

I am thrilled to report that Speedy's urethra is summer sore free. Some time during the two weeks that Speedy stayed at STC Dressage - Sean Cunningham, owner and trainer, took really good care of both boys, the summer sore cleared up and has stayed gone. And despite being completely gross and disgusting, the sock is still on!

I called the vet a week or two ago and asked if I should try to remove the sock or simply let it continue to ride around as is. Dr. Gonzalez, the other practicing vet at Bakersfield Large Animal Hospital, advised me to let it be as it is still acting as a barrier against the flies. As gross as it is - it gets saturated with urine every time Speedy pees, the sock doesn't seem to bother Speedy at all. Sometimes I can see it hanging out, but most of the time, he retracts it within his sheath so that only a tiny portion of the sock is visible.

Nothing to see here.

About every other day or so, I try to catch Speedy in a letting it all hang out moment so that I can check the condition of his urethra. Since it's tucked away in the sock, I have to roll the sock up so that I can get a clear view of things. He doesn't seem to mind the sock, but he does mind me poking around up in there. Thankfully, he is back to normal other than having his ding-a-ling wrapped up in a sweater.

I'll take a mare next time, please.

Still Gross

On Friday, I took Speedy to Bakersfield Large Animal Hospital to have his junk scraped and cleaned again. This summer sore business is no joke, it's not cheap, and it also (probably) really hurts. Poor Speedy.

At least the horses always have a nice view.

Since Speedy is so shy about his man parts, there was no way to assess the state of the summer sore without giving him a sedative. Izzy's ding dong hangs out all the time allowing me a daily opportunity to check things out; I know his penis is in good shape. I wish Speedy weren't so reserved. Before Dr. Tolley could do anything else, he had to give Speedy a little mid-morning cocktail.

The summer sore wasn't nearly as ugly as it had been the week before, but Speedy's body is still working overtime to get rid of the Habronema larvae. Instead of just ignoring the little larvae that are trying to burrow through his urethra (so, so gross), Speedy's immune system is launching a full scale attack, killing the larvae which leaves yellow granules of dead larvae. At least his skin tissue hasn't gone necrotic this time, but Dr. Tolley explained that the remnants of the larvae do create a sore that is painful. And since the sore is in Speedy's urethra, it probably feels like what you think it would. Not good.

I thought Dr. Tolley dug deeply the last time we were there, but for this visit, he really got in there. I didn't know the urethra could be opened that much, but obviously it can. Dr. Tolley was especially thorough this time around. He wanted to be sure to catch every bit of dead larvae that was stuck. Once the larvae is completely removed, Speedy's body won't have anything to which to react.

Once Dr. Tolley felt confident that Speedy's urethra was free of Habronema larvae, he and Dr. Gonzalez put a fresh sock on Speedy's penis. Based on my feedback about the last one, he decided to keep this one long. The purpose of the sock is to act as a barrier around Speedy's penis much like a mosquito net around your bed. If the flies can't get to his lil' dude, they can't lay eggs on it. In addition, Dr. Tolley gave me a liquid steroid that I am "painting" on the sock which should soak through to cover the top of Speedy's penis. The steroid is supposed to reduce the inflammation and reduce Speedy's reaction to the flies.

The Sock

For the next two weeks, Speedy will get his penis and/or sock (depending how long the sock stays on) painted with a liquid steroid twice a day. He'll also get covered in fly spray twice a day. Every other day he'll get a 5 cc/mL injection of Dexamethasone. He is also going to stay in the barn at STC Dressage in Moorpark which has a fly system. Unfortunately, this is all we can do for him. His body simply has to stop reacting to the fly larvae. It would be much simpler for him if the larvae could just pass through his system, land in his gut, and get pooped back out as eggs that hatch into flies.

My fingers are crossed that this next two weeks clears things up.

Oh, Boy, Was That Ever Gross

6/3/2021

If you are squeamish, simply read the condensed version that follows. If you dig learning about all of the weird crap that can happen to horses, stay tuned. It's about to get weird(er). Here's part one.

Short Version:
Speedy does indeed have a summer sore in his urethra. Summer sores are caused by fly larvae. They typically occur on a horse's moist areas such as eyes, corner of the mouth, and occasionally, the penis. Treatment includes steroids, to reduce the inflammation and allergic reaction, and dewormers.

Long Version:
Holy hell, summer sores are gross, creepy, and not something you ever want your horse to have anywhere near his junk. As I suspected, Dr. Tolley thought I should bring Speedy in, and the sooner the better. I called on Tuesday morning, and we were there by 2:45 that afternoon.

I unloaded Speedy and walked straight into the hospital's examining bay. Dr. Tolley didn't mess around. He asked a few questions, and then he brought out a sedative. Speedy has proven to be a roaring dragon when he's in the stocks getting messed with in a serious way, and Dr. Tolley wanted no part of that business as he was messing with Speedy's ... business.

As soon as Speedy's lil' dude dropped, Dr. Tolley took hold and peered closely at the urethra. It was nasty. I mean, I had seen it, felt it, and held it up close and personal, but seeing it exposed in full daylight without Speedy snapping it back inside showed how disgusting and crusty it was. What Dr. Tolley had to do next made it all even worse.

Dr. Tolley used a very pointy pair of scissors and dug inside the tube of the urethra, scraping and scooping all of the funk out. As Dr. Tolley is wont to do, he scraped the gunk into my hands for examination. Speedy isn't always the best patient, and I am a hands on type of client, so Dr. Tolley long ago gave up using "real" assistants. I am now the assistant, so handing him the soaking cotton and squirting soap onto it as he passed me the necrotic tissue to examine was no big thing.

Even sedated, Speedy wasn't too happy to have the inside of his you-know-what scraped with a long pointed object. I couldn't blame him. Before long, the dead tissue was scraped away and blood was dripping to the floor. I didn't know you could dig into that little opening quite that far, and I am sure Speedy wasn't aware of that fact either. Either way, it had to be done.

While Dr. Tolley is happy to explain what he's doing, I have learned to be a tiny bit patient and let him do his job. So while I wanted to keep asking, and then what are you going to do? I didn't, but I so wanted to. Instead, I waited and watched. Once Speedy's manhood seemed to be free of all things nasty, Dr. Tolley brought out some Elastikon tape and a thing that looked like a baby sock. Yes, you read that right, and yes, it was actually a penis sock. Dr. Tolley didn't call it that, but that's what it was.

Unlike vet wrap, which only sticks to itself, Elastikon sticks to everything. In fact, if you were to wrap it around your arm, you would lose all of the hair once you pulled it off. It is STICKY. I can see you doing the math right now, and yes, you would be right. Dr. Tolley wrapped that super sticky tape around Speedy's ding-a-ling and actually WANTED it to stick. Before wrapping it around though, he first slipped Speedy's penis into the sock and then taped the sock to his penis using the super sticky Elastikon. I swear this was not a scene from the movie American Pie.

Once the sock was taped securely in place, Dr. Tolley applied a huge handful of Triamcinolone Cream - the same steroidal cream he prescribed for Izzy's gnat bites, to the entire head of Speedy's very tender doodle. Before finishing completely, he also gave Speedy a dose of dewormer and an injection of Dexamethasone. Once all of that was finished, Speedy was taken to a paddock, and Dr. Tolley and I had a powwow.

What I wanted to know (and I am sure you do, too) is how did that happen, and what the heck does one have to do to not let it happen again? In short, summer sores are the result of a nematode (worm). Rather than explain the life cycle, read this bit from Arizona Equine (full article here):

Summer sores are commonly found on the lower limb, corner of the eye, and the urethral process of geldings and stallions. They can also be found on the face neck or any other area of the body that has had an open sore or wound. They are characterized by a non-healing sore with small yellow granules, and decayed tissue.

The adult worms live in your horse’s stomach. The eggs are passed into manure where flies ingest them. The larvae then move to the mouthparts of the flies and get deposited on moist areas of your horse while the flies are feeding. The routine life cycle occurs when the fly lands on the horse’s mouth, the larvae are deposited and swallowed.

Flies are attracted to different areas on the horse for feeding, mouth, eyes, wounds and sheath. Any skin abrasions or wounds are also potential sites for the larvae to set up housekeeping. The larvae do some damage directly simply by migrating into tissues and causing irritation. The larvae cannot live in these areas. Much of the reaction is from the horse’s own immune system responding to the larval invaders.

For now, I'll be giving Speedy injections of the Dexamethasone for the next ten days, applying liberal amounts of Triamcinolone Cream to his kicky-wicky, and dousing him with fly spray. Because his body's immune system is over-reacting, his eyes are also filled with puss because of the flies, so I am adding an ointment as often as possible. And while Izzy will probably have them torn to bits, I covered Speedy with a fly sheet and fly mask. Surprisingly everything, including the penis sock, was still in place yesterday afternoon.

Normally, Speedy is fly-free. I don't know why they've bothered him so much this year. I rarely even use fly spray on him, and they are never on his face. They love Izzy instead. My fingers are crossed that we can kill off any lingering Habronema. My boys are wormed regularly, but since not everyone worms their horses, reinfection is possible.

And that my friends, is one of the grossest things one of my horses has ever had!

Oh, Boy

6/1/2021

Uh-oh. Speedy has a boy problem that has me quite concerned. Sometime in the spring, I cleaned both boys' sheaths. They're really good about me doing them, and I am not squeamish.

A few weeks ago, I noticed that Speedy wasn't dropping all of the way to urinate, so I've kept my eye on things. Over the weekend, I realized that I needed to do more than keep on eye on things when I saw his urine spray out like water from a clamped off hose.

If you've never seen male horse urinate, it shouldn't look anything like what comes from a pressurized hose. I grabbed some Excalibur Sheath Cleaner and a bucket of water. I carefully worked my hand and arm up into his sheath, scrubbing gently as I went.

If you've never cleaned a horse's sheath, I'll spare you the worst of the details, but it's rather funky up in there. The only way to describe what comes out is shmegma - clumps of black gunk.

Yeah. Kind of like that.

This next part is not safe for kids. Little by little I was able to work my hand up to Speedy's actual penis, tucked up like a turtle in its shell. As gently as I could, I poked around his man parts until I could feel his urethra. It was quite swollen and crusty. It is not supposed to be crusty. In fact, the little tube should be very soft and squishy. Speedy's is not.

I gently picked away at it removing the blockage as best I could. Normally, when a gelding gets a "bean," it will be gray in color and almost feel like clay or wax. The junk that Speedy has in his urethra is hard and feels like compacted hay and dirt. I was able to remove a good portion of it, but without getting the penis to drop, it's really hard to see how bad the problem actually is.

You get the idea.

Yesterday, I repeated the cleaning, hoping that things might have softened up overnight. They did not. I was able to get the inside of his sheath very clean, but the urethra is definitely still clogged. Speedy always pees when I bring out his bucket of feed, so I made sure to time the arrival of the bucket for a time when I could closely watch him pee. To say it is a Pavlovian response would be very correct.

Speedy trusts me, so as he was peeing - oh my gosh this is so gross, I reached over and grabbed his penis to see what the urethra looked like as he urinated. Not good was the answer. He doesn't seem like he's in any pain, but things are definitely not right "down there."

Ivan Pavlov (1849 - 1936)

I will be calling Dr. Tolley today for some advice. Does Speedy need to go in? Should I just continue trying to soften and clean it? I'll let you know what he says.

Boys and their junk.
