How to treat hives from dog allergy
Dog Hives
What Are Dog Hives?
Hives (also referred to as urticaria) are areas of the skin that appear reddened and raised. Just as with humans, hives can be very itchy for your dog. Theyre a sign that an allergy is causing the immune system to overreact.
Hives can appear very quicklyand disappear just as quickly. The raised red area of the skin is referred to as a wheal, and it can appear anywhere from a few minutes to hours after exposure to an allergen. Wheals can appear anywhere on your dogs body, but theyre usually found on the head, neck, back, stomach, and legs.
In mild cases, the hives will generally disappear within 12-48 hours after contact with the allergen. However, because of the risk that the reaction can worsen to dangerous swelling of your dogs airways or a serious allergic reaction called anaphylaxis, you should seek out treatment any time you see hives on your dog. This is especially true for hives that occur on the face or around the throat, which can lead to dangerous swelling and possible blockage of the airways.
Symptoms of Dog Hives
Red raised areas of skin called wheals, which can occur anywhere (including mucous membranes) but are most commonly seen on the head, neck, back, abdomen, and legs
Intense itching
Excessive drooling if the mouth is swollen
Swelling (angioedema), which is particularly concerning when it involves the face and respiratory system and can have severe and life-threatening consequences
Causes of Dog Hives
The allergen that causes the hives may be environmental, chemical, or dietary. Any allergen your dog is sensitive can also lead to hives. Common causes include:
Insects bites, chemical contact, and medications are the most common.
How Vets Diagnose Hives
Your vet will closely examine your dog to locate the distinctive wheals associated with hives. Wheals typically have hair on them, and may appear in clusters. Beyond the physical examination, other parts of the diagnosis include:
Any history you are able to provide; be as thorough as you can in describing allergens your dog might have come into contact with and when and where you first saw the hives
Your dogs response to treatment
Treatment for Dog Hives
Dogs with hives usually respond quickly to treatment, which may include:
At-home treatments may include:
Cold compresses over the hives or swollen areas to give relief from itching
Antihistamines, but only under the supervision of your vet
Management of Dog Hives
Work with your vet to determine the cause of the hives, using both your dogs health history and history of exposure to allergens. Depending on the cause and the frequency, your vet may recommend:
Allergy testing to confirm environmental allergens
Immunotherapy treatment to desensitize your dog to specific allergens
A food trial to find ingredients that cause a reaction and develop specific dietary recommendations

Hives and Rashes (Urticaria) in Dogs
Hives or skin rashes (urticaria) are localized patches of red, swollen, usually itchy, skin. They often develop and disappear suddenly. Hives are relatively uncommon in dogs. The most frequent causes are insect bites or stings, shampoos, and medications. Other causes include contact with toxic plants or chemicals. Friction, sunlight, heat, exercise, stress, and genetic abnormalities may cause or intensify the rash. Hives may develop after inhaling or consuming allergens. Hives can be seen while a dog is in estrus ("in heat") or seen in puppies with intestinal parasites ("worms").
The wheals (eruptions) appear within a few minutes or hours of exposure to the causative agent. In severe cases, the skin eruptions are preceded by fever, poor appetite, or dullness. They can develop on any part of the body but occur mainly on the back, flanks, neck, eyelids, and legs. In advanced cases, they may be found on the mucous membranes of the mouth, nose, lining of the eyes, rectum, and vagina.
Often, hives disappear as rapidly as they arise, usually within a few hours. Treatment may not be required. They may return rapidly if exposure to the cause is not eliminated, however. Also, if your dog develops hives after receiving a vaccination or medication, contact your veterinarian immediately to see if treatment is needed. Treatment may include rapid-acting corticosteroids. If hives are chronic, environmental or food allergens should be considered as potential causes. Death does not commonly occur, unless anaphylaxis (a severe allergic event) or swelling of the respiratory tract is present.

Why Does My Dog Have Hives?
Seeing red spots on your dogs skin and watching him itch them furiously can be a bit alarming.
And finding out that your dog has hives from allergies or another cause can be even scarier.
While you can treat hives with a strong allergy medication most of the time, hives can also be the symptom of a life-threatening condition.
Heres what Dr. Ursula Oberkirchner, a veterinary dermatologist and owner of Advanced Veterinary Dermatology in Florida, had to say about hives on dogs, and what to do if you see these allergy bumps on your pup!
What are dog hives?
Hives on dogs, or urticaria, are most often caused by an allergic reaction, which means they develop after your dog is exposed to something hes allergic to.
Hives are a very characteristic symptom of an allergic-type reaction, Dr. Oberkirchner told The Dodo. Typically, hives develop within minutes or hours after exposure to the allergen.
Hives can be totally harmless and simply require an allergy medication to get rid of but sometimes they can mean something else is wrong.
Depending on the number, size and location of those hives, and if they are accompanied by other symptoms, such as trouble breathing or vomiting or diarrhea, hives can be a minor symptom or be part of a serious, even life-threatening, condition, Dr. Oberkirchner said.
An example of a life-threatening condition that causes hives includes anaphylaxis, which is when a dog has an extremely severe reaction to an allergen.
Certain cancers can also cause hives on your dog.
Your veterinarian will be able to help you determine whats causing allergy bumps on your dog. A thorough work-up by a veterinary dermatologist is often beneficial to help identify the cause of the hives and to manage them accordingly, Dr. Oberkirchner said.
What do hives look like on a dog?
Hives look like soft bumps that can range in size from small pebbles to egg-size and can be localized to one area of the body or develop all over the body, Dr. Oberkirchner said.
How to get rid of dog hives
How a vet will treat your dogs hives will depend on how severe they are.
The appropriate treatment is commensurate with the severity of the symptoms, and can range from giving your pet an antihistamine by mouth to requiring hospitalization with intravenous fluids and steroids, Dr. Oberkirchner said.
If you choose to give your dog antihistamines, make sure they dont include any added ingredients like decongestants or alcohol.

Your vet might also prescribe other dog allergy treatments, including prescription medications like Apoquel, an injection (like Cytopoint) or steroids.
But truly the best form of treatment for dog hives is to figure out what your dog is allergic to and then keep him away from it, Dr. Oberkirchner said.
The key to long-term, successful management of hives lies within identifying what the pet is allergic to and, if possible, avoiding it in the future, Dr. Oberkirchner said.

People who are allergic to dogs may experience a rash, hives, or watery eyes when exposed to dog saliva or dog dander.
In many cases, symptoms of a dog allergy are mild, and a person may still be able to live with a dog if they can manage their symptoms. Some home remedies can reduce symptoms. However, the only truly effective way to eliminate dog allergies is to avoid exposure to dogs.
In this article, we look at symptoms of allergic reactions to dogs and ways to manage them, including home remedies and medical treatments.
Specific symptoms and when they occur depend on the severity of the allergy. People who have severe allergic reactions to dogs may experience symptoms soon after exposure, while those with more minor allergies may take longer to develop symptoms.
Symptoms include:
- a skin rash that is red or consists of small, red, raised bumps called hives
- nasal congestion
- a runny nose and sneezing
- itchy, red, and watering eyes
- coughing
- wheezing
- tightness in the chest and shortness of breath
If a person lives with a dog, it is difficult to make the environment allergen-free. Dog dander (dead skin cells) can linger in the air for a long time and can stick to household items, such as curtains, furniture, bedding, and carpets.
Hypoallergenic breeds of dogs shed less than others so they may be less likely to cause allergic reactions. However, some
The only sure way to eliminate dog allergies is by avoiding contact with dogs. However, if a person does spend time with dogs, the following home remedies may help them to manage symptoms:
- Using a saline sinus rinse. Rinse the nostrils using a mixture made of 3 teaspoons of salt (iodine free), 1 teaspoon of baking soda, and 8 ounces of warm water. Use an ear dropper to put the solution into the nostril or purchase a sinus rinsing device from a pharmacy or online.
- Plant supplements. Taking certain plant supplements, such as those containing rosmarinic acid, may reduce allergy symptoms according to a 2014 study.
Lifestyle tips that can reduce the impact of dog allergies include:
- avoiding touching eyes or face after contact with dogs
- washing hands with soap after contact with dogs
- avoiding close contact with dogs, such as hugging or kissing them
- using a vacuum cleaner designed to trap and contain airborne allergens
- cleaning the house, washing the bedding weekly, and keeping the house tidy
- cleaning more often during winter months
- restricting dogs to specific rooms or spaces
- keeping dogs out of the bedroom and off furniture
- bathing dogs every 1 to 2 weeks
- wearing a dust mask and gloves while cleaning or in areas with dogs
- brushing and cleaning dogs outdoors when possible
If anyone is considering bringing a dog into their home, they should do an allergy test or undertake a trial period before committing to this.
There are over-the-counter (OTC) and prescription medications available that can help reduce or resolve the symptoms for people who are allergic to dogs.
OTC remedies for dog allergies include:
Antihistamines
Antihistamine medications block histamine, a compound that helps initiate local immune responses and cause allergy symptoms. Popular OTC brands for long-term exposure may contain loratadine, cetirizine hydrochloride, or fexofenadine hydrochloride.
Antihistamines can be bought online or obtained on prescription from a doctor.
Nasal decongestants and nasal corticosteroids
These medications help reverse the inflammation caused by immune responses and relieve nasal congestion. Some nasal corticosteroids are now available without a prescription and can be purchased online.
Immunotherapy
An allergist (a specialist in diagnosing allergies) may treat severe or chronic allergy symptoms using immunotherapy, also known as allergy shots.
Immunotherapy involves injecting allergens into a person in gradually increasing amounts. These allergy shots help a person to build a tolerance to allergens. It usually takes several sessions over several months to complete immunotherapy.
Other treatments
Many people with pet allergies also have asthma, and exposure to the pet allergens can cause asthmatic episodes or worsen a persons symptoms. In these situations, a doctor may prescribe inhalable corticosteroids or bronchodilators that help keep the airways open.
Dogs produce a variety of proteins that cause allergies in some people. The highest concentrations of these proteins are in dog saliva, with lower amounts found in dander and urine.
Dander tends to build up on hair follicles, so dog hair usually carries a large number of allergens.
If a doctor thinks that a person may be allergic to dogs, they will refer them to an allergist.
In most cases, an allergist will use a skin-prick test to diagnose allergies.
During a skin-prick test, an allergist will put a droplet containing a tiny amount of dog proteins onto the skin. They will then make a small prick in the skin, allowing the mixture to enter the body.
Most people who are allergic to the mixture will have a response within 15 to 30 minutes.
Sometimes, an allergist will decide that an individual who thinks they are allergic to dogs is actually responding to other allergens commonly found on dogs or dog hair, such as dust or pollen.
People who are allergic to dogs can get relief from symptoms by avoiding dogs and places where there are dogs. Many people choose to manage their symptoms by making lifestyle adjustments, such as more frequent housecleaning, but this can be extremely challenging.
OTC medications, such as antihistamines and nasal decongestants, can also help a person reduce or manage their allergy symptoms.
People with more severe or chronic dog allergies should speak with a doctor about prescription medications and therapies that can help manage symptoms.
