What is strangles in horses and how dangerous is it? Strangles is a highly contagious respiratory disease caused by the bacteria Streptococcus equi that can cause serious complications if left untreated. The good news? With proper care, most horses make a full recovery!
I've seen firsthand how quickly strangles can spread through a barn - one sick horse can infect an entire herd within days. That's why it's crucial to recognize the early signs: fever over 101.5°F, thick yellow nasal discharge, and those telltale swollen lymph nodes under the jaw that look like golf balls.
The key to protecting your horse? Vaccination, strict quarantine protocols, and immediate veterinary care at the first sign of symptoms. In this guide, we'll walk you through everything you need to know about identifying, treating, and preventing this pesky but manageable disease.

Understanding Strangles in Horses
What Exactly Is This Pesky Disease?
Picture this: your horse suddenly develops swollen lymph nodes that look like golf balls under their jaw. That's strangles - a highly contagious respiratory disease caused by the bacteria Streptococcus equi. It's like the equine version of a really bad cold that decided to throw a party in your horse's lymph nodes.
While any horse can get strangles, young to middle-aged horses who socialize frequently (you know, those social butterflies of the pasture) tend to be most at risk. The bacteria spreads faster than gossip at a barn party - through nose-to-nose contact, shared water buckets, or contaminated equipment. Before you know it, one sick horse can turn into an entire barn outbreak.
Why Should You Care About Strangles?
Here's the deal: strangles isn't just some minor sniffles. It can seriously impact your horse's health and your wallet. Treatment costs can add up quickly, and the required quarantine period might disrupt your riding plans. But here's the good news - with proper knowledge and prevention, you can significantly reduce the risks.
Did you know that some horses become "silent carriers" after recovery? They might look perfectly healthy but can still spread the bacteria to their buddies. That's why understanding strangles is so crucial for every horse owner.
Spotting the Signs: Strangles Symptoms

The Classic Symptoms You Can't Miss
Let's play detective for a moment. What should you look for? The first clue is usually a fever - your horse's temperature shooting above 101.5°F. Within a few days, you might notice:
- A thick, yellow nasal discharge that looks like melted cheese
- Swollen lymph nodes under the jaw that feel like squishy stress balls
- Your normally energetic horse acting like they partied too hard last night (lethargy)
- Turning up their nose at dinner (decreased appetite)
Here's an interesting fact: the disease gets its dramatic name because those swollen lymph nodes can sometimes press on the windpipe, making it sound like the horse is being strangled. Talk about a scary situation!
When Things Get Complicated: Bastard Strangles
Now, let's talk about the weird cousin of regular strangles - bastard strangles. This occurs when the infection decides to go on a road trip through your horse's body, forming abscesses in unexpected places like the abdomen or even the brain.
How would you know if your horse has this rare but serious complication? Watch for:
| Symptom | What It Looks Like |
|---|---|
| Colic signs | Your horse acting uncomfortable, looking at their sides, or rolling |
| Neurological issues | Circling like they're lost, pressing their head against walls, or having a wobbly back end like they've had one too many apples |
If you notice any of these red flags, it's time to call your vet immediately. Bastard strangles is like that uninvited guest who overstays their welcome and causes trouble - it needs professional intervention.
From Exposure to Infection: How Horses Get Strangles
The Bacteria's Journey Through Your Horse
Ever wonder how this whole strangles situation starts? It begins when your horse inhales or ingests the bacteria - maybe from sharing a water trough with an infected buddy or getting a friendly nose-to-nose greeting.
The bacteria then pull off a sneaky maneuver, crossing the mucous membrane barrier and hitching a ride in the bloodstream straight to the lymph nodes. This is where they set up camp and start multiplying like rabbits. As their numbers grow, they form abscesses that swell those lymph nodes to alarming sizes.
Here's a question you might be wondering: Why do the lymph nodes swell so dramatically? Well, it's your horse's immune system going into overdrive, trying to wall off the infection. Think of it like building a fortress around invading troops - effective, but it creates quite a noticeable bulge.

The Classic Symptoms You Can't Miss
Certain scenarios make strangles transmission more likely. If your horse:
- Boards at a busy stable with frequent new arrivals
- Travels to shows or events regularly
- Shares equipment with other horses
- Drinks from communal water sources
...they're basically playing Russian roulette with strangles. The more horses they interact with, the higher the risk. That's why many competition barns implement strict biosecurity measures - they've seen how quickly strangles can spread through a group of horses.
Getting a Diagnosis: How Vets Confirm Strangles
The Detective Work Begins
When you bring your vet a horse with suspicious symptoms, they'll start by playing medical detective. They'll ask about your horse's recent activities ("Has he been to any shows lately?"), check for those telltale swollen lymph nodes, and probably take your horse's temperature.
But here's the thing - many diseases can cause similar symptoms. That's why vets often recommend diagnostic testing to confirm strangles. They might:
- Swab the nose (like a COVID test for horses)
- Perform a nasal wash to collect deeper samples
- Do a guttural pouch flush (a special procedure requiring video guidance)
- Take a sample from swollen lymph nodes
Ever wondered why vets need to test if the symptoms seem obvious? Great question! Some horses can carry the bacteria without showing symptoms, while others might have similar symptoms from different infections. Accurate testing ensures proper treatment and quarantine decisions.
Understanding Test Results
The samples usually go for either culture (growing the bacteria in a lab) or PCR testing (a faster molecular method). Here's a quick comparison:
| Test Type | Time to Results | Pros | Cons |
|---|---|---|---|
| Culture | 2-3 days | Cheaper, confirms live bacteria | Can miss early infections |
| PCR | 1 day | More sensitive, faster | Can't tell live from dead bacteria |
Your vet will recommend the best option based on your horse's situation. Sometimes they might run both tests to be thorough.
Treatment Options: Helping Your Horse Recover

The Classic Symptoms You Can't Miss
Most strangles cases focus on supportive care - basically helping your horse feel comfortable while their immune system fights the infection. This includes:
- Keeping them hydrated (encouraging water intake)
- Making sure they eat (appetite stimulants if needed)
- Managing fever and discomfort (meds like Banamine)
- Providing a quiet, comfortable quarantine space
Think of it like when you have the flu - you want chicken soup, blankets, and Netflix. Your horse needs their version of TLC while they recover.
When Things Get Serious: Advanced Interventions
In severe cases where those swollen lymph nodes are seriously compromising breathing, your vet might need to perform a temporary tracheostomy (creating an alternate airway). It sounds scary, but it can be lifesaving when the regular airway gets too compressed.
The real turning point comes when those abscesses finally rupture and drain. It might look gross (okay, it definitely looks gross), but it's actually a good sign - it means the infection is coming out. Your vet might have you apply warm compresses to encourage this process.
After drainage, the area needs careful cleaning to prevent spreading bacteria. Your vet will show you how to gently flush the site with sterile saline - think of it like washing out a really nasty cut.
Prevention Strategies: Keeping Strangles at Bay
The Vaccine Debate: To Shoot or Not to Shoot?
Vaccination can be a valuable tool in strangles prevention, especially for horses at high risk. There are two main types:
- Intramuscular (IM) vaccine: Given like a typical shot, but can rarely cause abscesses as a side effect
- Intranasal vaccine: Squirted up the nose, may cause temporary sniffles but generally fewer side effects
Here's something important: you shouldn't vaccinate during an outbreak. It's like adding fuel to the fire. Always consult your vet about the best vaccination strategy for your horse's specific situation.
Biosecurity: Your First Line of Defense
Whether or not you vaccinate, good biosecurity practices are essential. Here's what works:
- Quarantine new arrivals for 2-3 weeks before introducing them to the herd
- Don't share equipment between horses without thorough cleaning
- Disinfect water buckets and feed tubs regularly
- Monitor temperatures twice daily during outbreaks
- Care for healthy horses before sick ones (and shower/change clothes after handling quarantined horses)
Think of biosecurity like washing your hands during flu season - simple habits that make a big difference in preventing disease spread.
Life After Strangles: Recovery and Long-Term Management
The Road to Recovery
Once those abscesses rupture and drain, your horse will start feeling better surprisingly quickly. But here's the catch - they can still spread bacteria for up to six weeks after seeming recovered. That's why follow-up testing is so important before ending quarantine.
During recovery, your horse needs:
- Plenty of rest (no heavy work until fully healed)
- Continued isolation from other horses
- Separate grooming equipment
- To be cared for after healthy horses (with proper hygiene afterward)
Most horses develop immunity after recovering, but some become those sneaky silent carriers we mentioned earlier. That's why some barns require negative test results before accepting horses with a history of strangles.
Watch Out for Purpura Hemorrhagica
In rare cases, strangles can lead to a secondary condition called purpura hemorrhagica (PH). This isn't contagious, but it causes inflammation of blood vessels leading to:
- Swollen head (like an allergic reaction)
- Puffy legs and belly
- Red spots on gums and mucous membranes
The good news? PH usually responds well to treatment with antibiotics and steroids. But it's definitely something to watch for during and after strangles recovery.
Frequently Asked Questions About Strangles
Can Horses Fully Recover From Strangles?
Absolutely! With proper care, most horses bounce back completely. Many even gain immunity that lasts several years. The key is catching it early and following through with the full treatment and quarantine protocol.
What's the Survival Rate?
For straightforward cases, the survival rate is excellent - we're talking 90%+. Complications like bastard strangles or PH decrease those odds, which is why prompt veterinary care is so important.
Can Humans Catch Strangles?
While extremely rare, yes - the bacteria can potentially infect people too. It's another good reason to practice excellent hygiene when caring for a horse with strangles. Wash those hands like you're prepping for surgery!
How Long Does Quarantine Last?
Until your vet confirms through testing that your horse is no longer shedding bacteria - typically at least 4-6 weeks after symptoms resolve. I know it seems long, but it's better than risking an entire barn outbreak.
Final Thoughts on Strangles Prevention
Making Smart Choices for Your Horse
After all this strangles talk, you're probably wondering how to best protect your horse. Here's my advice:
- If your horse travels or boards, seriously consider vaccination after discussing with your vet
- Implement strict biosecurity, especially with new horses
- Know the early symptoms so you can act fast
- Have a quarantine plan ready before you need it
Remember - an ounce of prevention is worth a pound of cure. Spending time and money on prevention beats dealing with a full-blown strangles outbreak any day.
Building a Relationship With Your Vet
Your veterinarian is your best ally in strangles prevention and treatment. Don't hesitate to ask questions or voice concerns. A good vet will appreciate an owner who's informed and proactive about their horse's health.
At the end of the day, strangles is a manageable disease when you're prepared. With the right knowledge and precautions, you can significantly reduce risks and ensure your horse stays happy and healthy.
The Economic Impact of Strangles Outbreaks
Veterinary Bills That Will Make Your Wallet Weep
Let's talk dollars and cents for a moment. A single case of strangles can cost anywhere from $500 to $5,000 depending on severity. Now multiply that by an entire barn outbreak, and you're looking at numbers that could make a Wall Street banker faint.
Here's a breakdown of where your money goes:
| Expense Category | Typical Cost Range |
|---|---|
| Diagnostic testing | $150-$400 per horse |
| Medications | $200-$800 per horse |
| Emergency vet visits | $300-$1,500 per visit |
| Quarantine setup | $500-$2,000 for temporary facilities |
And that's not counting the hidden costs like canceled shows, lost training time, or decreased property value if your facility gets labeled as a "strangles barn."
Insurance Nightmares and Legal Headaches
Ever tried explaining a strangles outbreak to your insurance company? It's about as fun as stepping on a Lego barefoot. Many equine insurance policies have specific exclusions for contagious diseases, leaving you holding the bag for those massive vet bills.
Then there's the legal side. If your horse spreads strangles to others at a show or boarding facility, you might find yourself facing lawsuits faster than you can say "guttural pouch." That's why many competition venues now require negative strangles tests before allowing horses to enter.
The Emotional Toll of Strangles
Watching Your Horse Suffer
No dollar amount can measure the heartbreak of seeing your beloved horse in pain. Those swollen lymph nodes look painful (because they are), and the nasal discharge makes even the toughest horse owners want to cry. You'll find yourself spending sleepless nights checking on them, worrying if they're eating enough, and praying those abscesses rupture soon.
And let's be honest - cleaning up all that gross discharge isn't exactly glamorous work. But you do it because that's what horse people do. We show up, even when it's messy.
The Social Isolation Factor
Here's something they don't tell you in the horse manuals: strangles quarantine means human quarantine too. You'll need to avoid other barns, cancel lessons, and basically live like a hermit until your vet gives the all-clear. Otherwise, you risk becoming "that person" who spread strangles through the entire county.
Ever been ghosted by your riding buddies? Try having a horse with strangles. Suddenly, people who used to beg for trail rides won't return your texts. It's enough to make you want to move to a deserted island with your horse.
Alternative Treatment Approaches
Natural Remedies Worth Considering
While conventional veterinary care is essential for strangles, some natural approaches can support recovery. Many owners swear by:
- Manuka honey - applied topically to draining abscesses for its antibacterial properties
- Echinacea tinctures - to boost immune function (but check with your vet first)
- Warm saltwater compresses - to encourage abscess drainage
- Probiotics - to support gut health during antibiotic treatment
Just remember - natural doesn't always mean safe or effective. Always consult your vet before trying alternative therapies, especially with something as serious as strangles.
The Role of Nutrition in Recovery
When your horse has strangles, their nutritional needs change dramatically. That fever burns calories like a furnace, and the nasal congestion makes eating uncomfortable. Here's what works:
- Soaked hay cubes or beet pulp - easier to swallow when throat is sore
- Electrolyte supplements - to replace what's lost through fever and decreased drinking
- Small, frequent meals - instead of two large ones
- Appetite stimulants like B vitamins - when they refuse to eat
Think of it like feeding a sick kid chicken soup - you want nutrient-dense, easy-to-eat foods that won't further irritate their system.
Strangles in Different Horse Populations
Racehorses: A Special Challenge
Racehorse barns are like petri dishes for strangles. The constant movement of horses between tracks, the high stress levels weakening immune systems, and the close quarters create perfect conditions for outbreaks.
Trainers face impossible choices when strangles hits:
- Stop training and lose fitness (and potentially owners)
- Continue training and risk complications like bastard strangles
- Cancel races and lose entry fees and potential earnings
No wonder many racing stables implement military-level biosecurity protocols. One sick horse can derail an entire season.
Rescue Horses: The Silent Carrier Dilemma
Here's a sobering fact: many rescued horses arrive carrying strangles bacteria without showing symptoms. Rescue organizations walk a tightrope between helping needy horses and protecting their existing herd.
Some best practices have emerged:
- Mandatory 30-day quarantine for all new intakes
- Testing before mixing with the general population
- Separate staff for quarantine areas
- Clear disclosure to adopters about any strangles history
It's heartbreaking to turn away a horse in need, but responsible rescues know that introducing strangles could jeopardize all their animals.
The Future of Strangles Management
Emerging Diagnostic Technologies
Researchers are developing exciting new tools to fight strangles:
- Rapid stall-side tests - giving results in hours instead of days
- Whole genome sequencing - to track outbreak sources
- Improved guttural pouch treatments - targeting those stubborn carrier cases
Imagine being able to test your horse at home like a pregnancy test - that future might be closer than you think!
Vaccine Innovations on the Horizon
Current strangles vaccines have limitations, but new approaches in development could change the game:
| Vaccine Type | Potential Benefits | Development Stage |
|---|---|---|
| Recombinant protein | Fewer side effects | Clinical trials |
| DNA vaccine | Longer immunity | Lab testing |
| Live attenuated | Better mucosal protection | Early research |
While we're not there yet, the future looks promising for more effective strangles prevention.
Personal Stories From the Trenches
A Trainer's Nightmare Experience
Jessica, a dressage trainer in Florida, shares her strangles horror story: "It started with one lesson horse sneezing. Within two weeks, I had 12 sick horses and $15,000 in vet bills. The worst part? Losing clients who didn't understand why we had to cancel lessons for months."
Her hard-earned lessons:
- Now requires negative tests for all new boarders
- Keeps a separate quarantine barn always ready
- Educates clients about strangles upfront
"That outbreak nearly bankrupted my business," she admits. "Now I'm paranoid about biosecurity - and proud of it."
A Vet's Perspective on Prevention
Dr. Reynolds, an equine veterinarian with 30 years experience, has seen it all: "The smartest clients are the ones who vaccinate before traveling and quarantine religiously. The ones who think 'it won't happen to me'? Those are the ones calling me at 2 AM with a barn full of sick horses."
His top tip? "Treat every new horse as potentially contagious until proven otherwise. That mindset has saved more barns than any vaccine alone."
Creating Your Strangles Action Plan
Building Your Biosecurity Toolkit
Every barn should have these essentials ready before strangles strikes:
- Digital thermometer (and know how to use it)
- Disposable gloves and gowns
- Separate grooming kits for each horse
- Chlorhexidine or bleach for disinfecting
- Pre-printed quarantine protocols
Think of it like a fire extinguisher - you hope never to need it, but you'll be glad it's there if disaster strikes.
Developing a Quarantine Protocol
Your quarantine area should be:
- At least 30 feet from other horses (more is better)
- Downwind of the main barn
- Equipped with its own water source
- Staffed by dedicated caregivers when possible
And here's a pro tip: set up your quarantine area before you need it. Trying to create one during an outbreak is like building a lifeboat after the ship starts sinking.

FAQs
Q: How contagious is strangles in horses?
A: Strangles is extremely contagious among horses - it spreads faster than gossip at a county fair! The bacteria travels through direct contact, shared water buckets, or contaminated equipment. I always tell my clients that one sick horse can infect an entire barn within days if proper precautions aren't taken. That's why immediate quarantine is so important at the first sign of symptoms. The bacteria can survive in the environment for weeks, which is why thorough disinfection is crucial.
Q: What's the first sign my horse might have strangles?
A: The first red flag is usually a fever above 101.5°F - I recommend every horse owner keep a digital thermometer in their first aid kit. Within a few days, you'll typically see thick yellow nasal discharge and those characteristic swollen lymph nodes under the jaw. From my experience, horses often become lethargic and lose their appetite before the more obvious symptoms appear. If you notice these signs, isolate your horse immediately and call your vet - early intervention makes a huge difference in recovery.
Q: How long does strangles quarantine last?
A: Here's the tricky part - quarantine typically lasts 4-6 weeks after symptoms resolve, not just when your horse starts feeling better. I know that seems like forever, but horses can still shed bacteria long after they appear healthy. We usually recommend follow-up testing before ending isolation. During this time, care for affected horses last, use separate equipment, and shower/change clothes after handling them. Trust me, the inconvenience is worth preventing an outbreak!
Q: Is the strangles vaccine effective?
A: The vaccine can help reduce risk, especially for horses that travel or board at busy facilities. There are two types: intramuscular (which rarely causes abscesses) and intranasal (which might cause temporary sniffles). In my practice, I've seen vaccinated horses still get strangles, but usually with milder symptoms. The vaccine isn't perfect, but when combined with good biosecurity, it's another layer of protection. Always consult your vet about whether it's right for your horse's situation.
Q: Can strangles kill a horse?
A: While most healthy horses recover completely, strangles can be fatal in rare cases, especially with complications like bastard strangles or purpura hemorrhagica. The mortality rate is low (about 1-2%), but the disease can cause significant suffering and expensive treatments. That's why prevention is so important - an ounce of prevention is worth a pound of cure, as they say. With prompt veterinary care and proper management, the vast majority of horses bounce back just fine.
