These small raised wheals are extremely itchy, and if your horse scratches to excess, they may become even more inflamed or even rupture, which can lead to dangerous skin infections. Swelling that occurs in the throat and nasal passages is rare, but when it happens it can make breathing difficult, if not impossible.

Hives in horses are small rounded lumps and bumps on the skin; they are usually not painful or life threatening unless they cause the throat to swell. Urticaria, better known as hives, is an unexceptional skin condition for the horse.

Allergic reactions are the most common cause of hives, and the allergic reaction may be a response to allergens such as biting or stinging insects, ingested plants or insects, or to a substance that came into contact with the horse's skin. Hives have a distinctive raised appearance and are frequently diagnosed visually.

In many cases, the hives disappear on their own before the animal is even able to be evaluated by a veterinarian. Hives are caused by allergic reaction more often than by anything else, so determining the correct allergen is the primary focus.

Skin scrapings will often be taken from any areas that are affected by the hives or by other types of rash, for use in the microscopic examination of the skin cells to look for issues like signs of disease, mites, or yeast infections. Horses generally respond quite well to antihistamines, and very few equines develop either excitability or drowsiness from taking them.

Another option for relieving allergy symptoms in horses is called hyposensitization. Many cases of urticaria do not reoccur, and quite often the allergen or other cause may never be definitively diagnosed.

When the hives are persistent the prognosis for clearing up the lumps and bumps may be more guarded, although equine antihistamines are often helpful in relieving symptoms. This can include changing the horses usual feed, pasture, and stall.

I can't actually diagnose or prescribe anything without seeing Cody, and it would be best to have your veterinarian look at him before giving anything. Benadryl can be used safely in most animals for allergic reactions, but I can't say for sure that that is what is happening to him.

. My 24-year-old AQH broke out in hives and was laying down with no interest in food. He gets garlic every day, he is kept in his stall under fans during the day with turnout on pasture at night.

There are many possible causes for a breakout of hives in horses which may include bites from a variety of different insects especially during the summer months which is why it is best to keep horses stabled during the hours of dawn and dusk when insects are most active; fans in the stable are great in preventing flying insects as well as screens (if appropriate). “Just give him a dose of ex,” advises your trainer, speaking of dexamethasone, a steroid commonly used to treat skin conditions.

When your horse is exposed to allergens (substances that trigger an allergic reaction), they bind to an antibody called IGE that’s circulating in his blood stream. In some cases, the fluid within the hive will even leak out of the skin, causing scabs and areas of hair loss.

The good news is that hives are rarely dangerous and, surprisingly, they don’t make your horse terribly uncomfortable. Still, if your horse has hives (especially if they’re accompanied by scabs and hair loss), you’d probably like to make them go away eventually.

It’s more likely it was just the “final straw” that pushed your horse’s allergy response over the threshold level required for him to develop hives. Otherwise, his body may well be pushed over that allergic threshold whenever a new allergen that’s “on the list” comes along, and he’ll get hives again.

The selection of different allergens used for intradermally skin testing is an extremely important part of formulating an effective treatment, and should be specific to your horse and his environment. Truth: Unfortunately allergies aren’t ever really “cured.” Unless you’re really lucky and your horse experiences an isolated reaction to some specific allergen, a dose of dexamethasone may eliminate the symptoms (hives) for the short term, but chances are they’ll be back.

Work with your veterinarian to explore some alternative medications to control your horse’s allergies. Some horses respond well to prescription antihistamines such as hydroxyzine or domain, or even over-the-counter options like Benadryl or Zyrtec.

Consult with your own veterinarian for help to formulate an effective medication plan for your individual horse. It’ll be a relief to know what to avoid in my horse’s lifestyle so the hives stop coming back.

Truth: There’s no question that allergy testing is the best answer for helping you to manage your allergic horse’s hives. In fact, most specialists agree that intradermally skin testing is much more accurate and effective.

With a blood test, the lab looks for allergen-specific IGE antibodies and generates a list of things that could contribute to your horse’s allergic response. The list of possible allergens is extensive and often includes substances that are irrelevant to your horse’s lifestyle.

From this list, the lab will generate a serum to be used to hyposensitize (desensitize) your horse through a series of allergy shots. The veterinarian carefully selects the allergens to test based on substances in your horse’s environment, so you gain horse-specific information.

You’ll learn what substances are most important to avoid, which means the allergens included in your horse’s allergy serum for hyposensitization will be much more relevant and specific. Myth: My horse’s hives were awful, so I started giving him allergy shots.

Truth: There’s no doubt about it, allergy shots or hyposensitization are the safest, most effective way to help your seriously allergic horse. Egg doesn’t have the same effect of binding with eosinophils and mast cells, meaning the substances that produces the allergic symptoms (hives) aren’t released.

Another misconception is that your horse’s hives may worsen in the day or two after you administer the allergy shot. You go out to visit your beloved equine companion to give him his evening meal, and when he comes into eyesight, you have to pick your jaw up off the floor.

You immediately assume that he is dying (we always jump to the worst conclusion, especially with our horses)! Upon further inspection, you note that he isn’t in any pain, just maybe a bit itchy and seems to only be impatiently putting up with this impromptu exam, so he can get his feed.

Putting in a call to the vet immediately comes to your mind and after you get them on the way you begin to try and piece together the puzzle. Hives (urticaria) is an outbreak of swollen, red bumps on the skin that come up suddenly.

Substances that can cause a horse to break out in hives may be ingested (feed, supplements, any oral medication, etc. ), maybe medications given by injection (such as vaccines, phenylbutazone, or penicillin), or maybe due to contact with the skin (bedding, tack or blankets, or topically applied substances such as fly sprays or certain shampoos).

Contaminants in hay or feed such as mold or other allergens that are inhaled may also cause a horse to get hives. When your veterinarian comes to check out the situation he/she will usually give a single dose of a short-acting corticosteroid that will usually help the hives go away.

The ideal therapy for preventing hives from plaguing your horse is to avoid or eliminate the triggering factors. Simple steps you can take include changing paddocks and bedding, eliminating supplements (at least for a trial period to see if this is what is causing the reaction), and going over any recently added medications with your veterinarian.

Recurrent or persistent hives may be treated with a more routine administration of low doses of steroids which can be kept at the barn (in your equine first aid kit). The appearance of hives on horse body is termed as Urticaria which are the pale red-colored, swollen bumps on the skin.

Hives can be a result of an insect bite, wrong type of food, pollen grains, excessive workout, stress, extreme weather, medications, changes in shampoo or conditioners, contact with an infected surface, or diseased animal, and ringworm. With proper care and controlling the main cause of this issue can let them go just in few hours on in severe cases, just one day.

Make sure to identify the cause of hives quickly so that you can cure it and give relief to your pet. He starts scratching his affected parts with some hard object and the already irritated and swollen pops burst in this way.

Using cold things like an ice bag on these bulges can help a lot in the reduction of swelling and redness. It is a must identify the actual reason so that you can find an immediate solution for it or seek some medical help.

Treating the skin wrong or mishandling can cause severe urticaria development with pain and discomfort. Washing it with cold water, applying an ice cube, ointment, avoiding sun exposure and anti-itch medications can help a lot to treat this issue.

Like if you are trimming him with a hair removing machine with gentle pressure, then this can be the first cause of the appearance of these protrusions. Be careful while cutting his hair and do not apply any pressure which triggers the sensory cells beneath the first layer to produce inflammation.

Similarly, if the blade of the trimmers cuts the little piece of skin and gets blood over it, then the germs will keep on multiplying if you will not wash the machine. The best thing is to use spirit or some rubbing alcohol on the blade to make it more hygienic and avoid infections, irritation, and sudden responses like these bulges.

A severe kind of sneezing starts in this situation which makes them tired and frustrated and the appearance of hives is the exact reaction of sniffing the pollen. There are so many of the foods which can cause an allergic response as a result of which hives appear and sometimes other different symptoms arise.

If you feed some peanuts to your pet, and he is allergic to it then he will become colic, flushing, tingling, hives, and losing consciousness are the main signs that appear. Whenever you are going to introduce a new food to your horse, feed it in a tiny amount for checking out any bad reaction.

Insects who have sting for biting others also have some chemicals in the mouth or back part of the body. Similarly, ants release formic acid on the skin they bite which causes mild to severe redness, swelling, and hives.

Bees and wasp have alkali in their sting and some other active venom which causes awful kid of pain and swelling. Rubbing a piece of onion or some chalk powder can soothe the affected area of insects attack and make the marks disappear.

In case of severe discomfort and ill condition, you should take him to seek medical assistance from the veterinary. You should immediately take your pet to a good vet so that he can prescribe medicines to deactivate the venom spreading inside him.

In such a situation, you have to tie the area where reptile has bitten your horse so that the poison may not spread further. Such conditions create hive marks and bathing him immediately is the perfect solution to it.

When your animal’s living area has no shade on it, and he keeps getting sun exposure all the time, then the rays can burn his skin. If he gets exposed to the sun even in summer then definitely he has to face issues related to his skin and health.

If you want to eliminate all such issues to give him relief then you should arrange a cool and shady place for him in summer. When you feed your horse without checking the food quality then it can also be the main cause of the formation of hives on skin and allergies.

If the hay or grains have fungus on it or it has been rotting and you give it to your pet without even noticing, then it can cause severe kind of harms on your health whose signs appear on the skin as well. Such kinds of things give painful marks on the skin which you can treat by not providing him with that food.

Select the food items for your animal wisely by keeping in mind its quality and freshness. Before trying every new food, one must give it a small amount to check for its reaction and then serve it as a complete meal.

In extreme cases, horses can get mouth ulcers, hives, diarrhea, and several other health issues. The only way to get rid of it is to make a relaxed and peaceful environment for your horse where there is no noise and enough amount of food to eat.

If your horse is struggling with some disease, then try to keep him happy by spending time with him, talking and loving can support a lot. You can also notice his physical activity, like in stress animals do not do his normal workout and appear sluggish.

You might think it as irrelevant but keep in mind that there is a big connection between mental state and physical health of the body. They get excited to see the big ground and start running there for a long time without even noticing that this much activity can hurt their muscles badly.

There is always a warning on every medicine to discontinue it in case of strange kinds of side effects. If this same case is happening to your stallion, like he's getting hives, marks, and other conditions like these then you should immediately discontinue the medicine and get help from the animal doctor.

If you have more than one pet and you give the same medications to your horse which the vet has prescribed to your other one in some disease or some ill-health condition, then you are doing completely wrong. Not only the skin conditions but the wrong tablets can also cause ulcers, constipation, diarrhea, and other symptoms.

Besides this, the chemical used in it to make the hair silky can also damage the sensitive skin and create hives on it. Similarly, every conditioner is not suitable for all hair types, when the wrong product comes in contact with the skin, then it irritates.

Select the right product for your pet and if you are unable to find the one for your horse skin and hair type, then you can ask some vet whenever you visit him for some issues. You can cover the body from the neck to the back with some cloth so that he may not come in direct contact with the allergic skins.

If he has a habit of eating mud or chalk because of some nutrient deficiency, then he is most likely to ingest ringworm. They get cravings to lick the chalk powder or mud several times a day.

The most common deficiency in his state is calcium which induces horses to taste something like mud and other things. But these types of items are not good for health, moreover, they have bacteria and worms in them which can cause monotonous conditions and stomach related problems like diarrhea, colic, etc.

Take care of your beloved and spend some time treating his issues so that he can stay safe from the bigger problems related to his skin and overall health. Photosensitization is a condition in which skin becomes overly sensitive to ultraviolet light (sunlight).

The photo dynamic compounds are energized by the UV light and cause chemical reactions that damage cells in the skin and lead to ulceration and fluid accumulation. Affected areas are usually those that are lightly pigmented or that have little hair, such as the lips, eyelids, and tips of the ears.

A common cause of hepatogenous photosensitivity is poisoning by grazing plants toxic to the liver or ingesting blue-green algae (cyanobacteria) or fungal toxins. Photosensitive animals are hypersensitive when exposed to sunlight and squirm in apparent discomfort.

They scratch or rub lightly pigmented, exposed areas of skin such as the ears, eyelids, or muzzle. When exposure is prolonged, fluid discharge, scab formation, and death of skin tissue can result.

While photosensitivity continues, animals should be shaded fully or, preferably, housed and allowed out only at night. The severe stress of photosensitization and extensive death of skin tissue can be highly harmful, even deadly.

My five-year-old Arabian gelding, Khoi, has had chronic mild hives for the past few months. The hives are small -- not really palpable on the skin, but the hair is raised throughout his neck, shoulders and withers.

(We live in Southern California, and this winter has been extremely mild -- no rain to speak of, no fires, just lots of sunshine and warm weather.) However, he's had shavings (same brand) his entire life, and has never demonstrated any allergic reaction, so I'm a bit confused as to why it might suddenly cause hives.

First, have you heard of a horse suddenly developing an allergy to something he's been exposed to for quite some time? Khoi lives in a stall with turnout, and is also turned out to pasture for a few hours per day.

He is fed grass hay twice a day, and 2-3 pounds of a mixture of oat-based supplement (Ruse Elite Performance) and alfalfa/timothy pellets, with a few cubes of alfalfa/timothy hay thrown in for good measure, which is moistened. He hasn't been exposed to anything different in the way of shampoo, fly spray, etc., nor does he share his brushes or tack with any other horse.

You've described the situation very clearly and thoroughly, and in the absence of any other obvious cause, I think that your vet is right, and your horse's bedding is indeed the most likely culprit here. Pine and cedar shavings smell nice to us, so we like to use them for our horses bedding, but this isn't a good idea.

If you find more and bigger hives on your horse, your vet will need to be told this immediately. If your horse needs treatment, your veterinarian has quite a few drugs to choose from: corticosteroids, antihistamines and non-steroidal anti-inflammatories, singly or in combination.

A really severe allergic reaction can turn into anaphylaxis, which would definitely qualify as a red-alert emergency. If you come to the barn and find your horse breathing much too fast, wheezing, or flaring his nostrils in an effort to get more air, or if you find him acting extremely twitchy and nervous, you should talk to your vet immediately.

Just a note: unless your horse is working hard and sweating profusely, you can leave the electrolytes out of his daily feed. They're helpful ONLY if a horse is sweating enough to create a significant loss of mineral salts.

While a mild case of hives or other allergic response, such as itchy or irritated skin, may appear mysteriously and disappear just as quietly on its own, it's worth your while to puzzle out what caused it. Allergic reactions can make a horse miserable, and they often become more serious with repeated exposure to the substance, or allergen, that triggers them.

In this article, two experts--veterinary dermatologist Stephen White, DVD, of the University of California Davis, and Sarah Gardner, DVD, an associate professor in equine medicine at North Carolina State University, discuss common allergic reactions. Inside and Out In an allergic reaction, your horse's immune system perceives a threat from something harmless and goes to Level Red, mounting a response that's entirely out of line.

Moreover, he becomes hypersensitive to the specific allergen and beefs up defenses against it--so the next time he's exposed to it, the reaction is likely to be quicker and stronger. It's an allergic reaction to the bites of Suicides, the tiny midges many people call “no-see-ums”.

Depending on the species, these insects typically bite your horse along the crest of his neck, around his dock or on his belly. The area becomes covered with an oozing, crusty rash that itches intensely, causing him to rub and scratch.

Could That Be Heaves” below for more about respiratory reactions, which erupt when internal swelling narrows breathing passages. Allergies also have been suspected in some cases of head shaking, a condition in which your horse constantly tosses or shakes his head during exercise.

This extreme, systemic allergic reaction is most likely to occur after repeated exposure to something to which your horse has become hypersensitive, and it usually appears quickly. That's done with quick administration of epinephrine (Adrenalin) to stimulate the horse's body and raise his blood pressure, and a corticosteroid such as dexamethasone to reduce internal swelling and open his airways.

Prime Suspects Insect bites are probably the most common cause of skin symptoms such as hives and pruritic, says Dr. White. Certain proteins in the saliva of Suicides, found worldwide, are known to trigger an allergic reaction in horses.

However, in these cases, it's not always clear whether a limited reaction (such as local swelling) results from a true allergic response or simple irritation from the bites. Environmental allergens include pollen, mold and dust that your horse inhales.

When a horse develops hives or other skin symptoms because of one of these substances, he's said to have an atomic dermatitis. Surprisingly, horses can be allergic to pollen from Bermuda grass, which grows widely in the southern half of the United States and is sometimes used for pasture.

For instance, Dr. White says, hives sometimes herald the onset of a case of ringworm, a common skin disease caused by a fungus. The horse first has an allergic reaction to chemical substances that the ringworm fungi produce.

The classic signs of this disease--hair loss in circular patches, with raised, scaly skin--soon follow. Breeders sometimes report cases where a horse shows the same allergies as its sire or dam.

Follow the Clues It may take some detective work to determine which of many possible factors causes your horse's symptoms. For a true allergy, suspicion falls first and heaviest on anything new in your horse's life--a new medication or a new grooming product.

If you try a different shampoo on your horse, and he breaks out in hives, obviously you'd suspect a contact allergy. If your horse erupts in crusty pustules and rubs his mane out in the spring, Suicides should top the list of suspects.

Keeping records of when and where your horse's reaction appears can help narrow down the range of causes. For example, if he's sprinkled with hives after a day in the pasture in September (ragweed season), then that plant's pollen is a strong suspect.

The dermatology service at the UC Davis veterinary clinic keeps a bank of about 70 allergens for testing. If you opt for testing, here's what to expect: Your horse is sedated, and an area of skin (usually on the neck) is shaved.

The cost varies with the clinic and the number of allergens tested, but it generally runs to several hundred dollars. Even a “normal” horse may show some reactions, so test results have to be put in context.

The answer has to fit the history (that is, the substance was something that your horse was or could have been exposed to) and the physical signs. Tests are useful mostly for atomic dermatitis (when a horse develops hives because of an environmental allergen such as pollen, mold and dust), Dr. White says.

They're also useful if a horse can't be sedated or clipped, or if he's on medications that could obscure the results of skin tests. Change your horse's hay and withdraw all grain, supplements and treats; if the problem doesn't go away, food is not a likely cause.

Keep horses that are sensitive to Suicides in during early morning and evening hours when these insects are most active. For skin reactions caused by pollen, mold spores or dust, hyposensitization--allergy injections--may be an option.

In fact, the main purpose of doing skin tests is to develop shots custom-tailored to your horse's allergies. Although protocols vary, a typical program might involve shots every other day for a month, then weekly.

A chronic cough, labored breathing, nasal discharge, exercise intolerance--those are classic signs of heaves, also known as broken wind, recurrent airway obstruction and chronic obstructive pulmonary disease (COPD). Allergies play a major role in heaves, which is a lot like human asthma, and affects about 12 percent of horses, says Sarah Gardner, DVD, PhD.

IAD produces milder signs than heaves, but it tends to affect younger horses. Triggers: Barn dust is the most common culprit in allergic respiratory reactions.

This is organic dust, full of mold spores, pollen and endorphins produced by certain bacteria. In horses predisposed to heaves, the dust irritates the airways and triggers an allergic bronchitis.

Some unfortunate horses (mostly in the Southeast) have “grass heaves” and develop seasonal signs while on pasture. Generally, skin tests aren't very helpful in isolating more specific causes for these reactions, Dr. Gardner says.

Management: Providing good air circulation in your barn and cutting down on dust--for example, by storing hay in a separate building and using low-dust bedding such as shredded paper--may reduce the symptoms. If your horse develops signs on pasture, he may do best in a clean, low-dust barn with turnout on a dry lot.

Medications: Drugs can help your horse breathe more easily while his lifestyle is adjusted. Sarah Gardner, DVD, PhD, is an associate professor at the College of Veterinary Medicine of North Carolina State University Raleigh, where she specializes in respiratory conditions.

They were also started on Elk Grove Milling Senior pellets around 1 yr ago. After our gelding had a colic scare we purchased some pasture grass from a friend.

Within a few days my mare started showing signs of hives. Finally, we switched her back to Alfalfa and the hives slowly went away.

We called the vet who advised used to give her a higher dose of Benadryl and start trial and error again to rule things out. We finally switched her back to Nevada Alfalfa, and she cleared up.

I feed timothy hay and Idaho alfalfa cubes. If the vet thinks it might be a pesticide reaction, I would take a sample to your local co-op for analysis or send it out for analysis. I would not be feeding something that had been treated with something that makes my horse sick -- if that's what it is.
