It’s always a good idea to keep an eye on the health and well-being of your equine companion and contact your veterinarian if anything appears off or abnormal. 

A thorough exam will allow them to accurately pinpoint any potential problems with their respiratory system early on so they can create a plan tailored specifically to your horse’s needs.

What to do if your horse has equine influenza?

When your horse has equine influenza, the best thing to do is to take immediate action and follow these essential steps. First and foremost, immediately remove your horse from contact with other horses and place them in an isolated area. 

Secondly, contact a veterinarian who can provide you with veterinary advice on how to proceed. Administration of vaccines is highly recommended, along with preventative measures such as doubling up on bedding and increasing ventilation in stables or barns. 

Finally, you should monitor the affected horse daily for symptoms such as coughing, loss of appetite, fever, or nasal discharge. By taking these steps and following your vet’s instructions carefully, you can help ensure that your horse recovers quickly and safely without subjecting other horses to the same illness.

How long does equine flu last?

Equine flu can be a real headache for horse owners and often has people asking “How long does equine flu last?” While symptoms vary in the severity of their presentation, most cases are typically cured within a few weeks after states of rest and closely monitored treatments. 

Without proper management and care, equine flu can cause serious detrimental effects on the horse’s health, including inflammation, infections, and breathing trouble. To prevent these issues from occurring, you must seek professional advice from your vet as soon as possible upon noticing any changes in your horse’s behavior. 

By ensuring that the duration of equine flu is kept to a minimum you will be well on your way to establishing the best conditions for a healthy life for your four-legged companion.

What causes horse equine influenza?

Horse equine influenza is a highly contagious virus that infects the respiratory system of horses, donkeys, and mules. It is caused by a specific type of bacteria known as Influenza A Virus subtype H3N8 and is easily spread from one animal to another. 

Horses contract this virus through contact with infected animals, contact with contaminated surfaces or items, and ingestion of contaminated food or water. Vaccines are available and highly recommended for horses that are kept in high-density horse populations or travel frequently. 

Symptoms of equine influenza include fever, coughing, nasal discharge, loss of appetite, and a general feeling of being unwell. The disease can range from mild to severe and can last from two to six weeks; however, if left untreated it can lead to bacterial pneumonia or death.

What medicine treats horse flu?

Horse flu is a serious illness that can be debilitating for horses, but thankfully there are treatments available to combat the virus. Currently, Equine Influenza Infection in Horses is treated with the administration of antiviral injections. 

Such medications work to reduce the severity and duration of symptoms by blocking the infectious agents from replicating within the animal’s body. Veterinarians typically prescribe a course of oral antibiotics along with these antiviral injections to prevent potentially more serious secondary infections from occurring. 

In some cases, medicated injected electrolytes may also be given to ensure adequate hydration levels as this particular virus is notorious for causing dehydration. The key to successful treatment of horse flu lies in early diagnosis and prompt intervention on behalf of the vet.

How do you treat equine influenza at home?

Treating equine influenza at home is a tricky affair and should be attempted with caution. It is important to pay attention to the signs exhibited by the affected animal and contact a veterinary practitioner right away if the symptoms become severe. 

If mild symptoms are observed, it is best to take preventive measures such as ensuring that the horse is thoroughly cleaned and not exposed to any other animals suffering from illness of any kind. 

It might also be beneficial to isolate the animal from other occupants of the stable so that there is minimal chance of cross-contamination. Furthermore, providing proper nutrition and dietary regimen goes a long way in ensuring full recovery for an infected horse. 

In addition, regular deworming can also help in boosting immunity against illnesses like equine influenza. All said it’s best to get professional help when dealing with this type of illness as a wrong diagnosis or treatment plan could make matters worse.

How do you prevent flu in horses?

For horse owners, taking precautions to prevent the flu is essential for ensuring that their animals remain healthy. The best way to protect against the flu is by getting your horse vaccinated annually. 

Additionally, as a preventive measure, you should also practice good hygiene habits in your stable—this includes providing clean water and feed bins and regularly changing bedding. 

You should also take extra care with visitors and foals who are kept away from the herd, as contagious viruses can be easily spread. 

Lastly, it’s important to carefully monitor your horses for any signs of respiratory distress such as coughing or nasal discharge, and contact a registered veterinarian at the first sign of illness. By taking these precautions, you can help ensure that your beloved equines stay happy and healthy!

What is the best flu vaccine for horses?

When it comes to taking care of your horse’s health, the best flu vaccine is essential. Horse flu is an incredibly contagious virus, and a vaccinated horse can provide invaluable protection for your herd against this sometimes life-threatening illness. 

Most commonly known as ‘Equine Influenza’ or ‘EHV-1’, selecting the right vaccine for your horse is important; with so many options available, it can be difficult to know where to start. 

Your vet should be able to steer you in the right direction when it comes to choosing the best flu vaccine for horses – the one least likely to cause adverse reactions, protecting without upsetting your horse in any way. 

Commonly recommended are Flu Avert I.N, Avian Influenza Vaccine (H3N8), and Rhino 4 Vaccines – but don’t feel like you have to take their word for it – do some research of your own before making a decision.

How often do horses need a flu vaccine?

They say an ounce of prevention is worth a pound of cure, and this is especially true when it comes to horses. 

Vaccinating your horse against the flu is one of the most important steps you can take to keep them healthy, as horses are notoriously susceptible to infections caused by equine influenza viruses which can quickly spread throughout a herd or stable. 

The experts generally recommend that adult horses receive their flu vaccine at least once per year, while young horses and those in close contact with other equines should be vaccinated every six months. 

Additionally, if you’re around other horses frequently–like if you show your horse or visit boarding facilities–it’s prudent to give your horse “booster” shots every two to four months just in case they’ve come into contact with another possibly ill animal. 

Taking the time to ensure your horse gets their flu shot on schedule can help minimize the risks of contracting equine influenza, ensuring your horse stays happy and healthy!


In conclusion, being aware of the early signs of equine flu in Shire Horses can help you spot the disease in its earliest and most treatable stage. 

It’s important to remember that these are just some generally accepted warning signs and symptoms, and any potential variations should be discussed with a professional vet. 

When it comes to our beautiful Shire Horses, prevention is key. Regular vaccinations, isolation from other horses, avoiding damp and dusty conditions, ground hygiene practices, and washing your hands after grooming will all help to reduce the risk of equine flu. 

Thankfully, with the right diagnosis and early treatment it can be easily managed; so keep an eye out for those signs – there’s nothing more precious than knowing our lovely horses are taken care of.
