Dog Hives (Urticaria | welts): Causes, Diagnosis & Treatment

What Are Dog Hives (Urticaria)?

Hives, otherwise known as urticaria by medical professionals, are one abnormality you may see. They occur when your dog is allergic to something, such as an insect, medication, or food. Recognizing hives in dogs and understanding the cause is essential to relieving your dogs discomfort and preventing dog hives in the future.

What do dog hives look like?

• Dog hives look like raised bumps on the skin, usually about the size of a nickel.
• Hives are usually red in color; however, you may not notice redness if they are on a very furry part of your dog. In this case, your pets hives may only look like fur-covered bumps. Sometimes, its difficult to see the raised bumps, and you may only feel them when petting your dog.
• Dog hives can appear anywhere on the body, including the face, tongue, neck, legs, chest, abdomen, or back. They can affect just one area of the body or the entire body.
• Dog hives are very itchy. This may be the first thing you notice before seeing or feeling hives on your dogs skin. Your dog will likely be trying to scratch, lick, or bite the areas affected as it will be itchy.
• Hives usually happen very fast within minutes after exposure to whatever caused them.
• You may notice excessive drooling and a swollen/puffy face if the hives affect your dogs throat or mouth.

What causes hives on a dog?

Dog hives are almost always related to exposure to an allergen. Once exposed to an allergen, mast cells in your dogs body release a substance called histamine. Histamine causes blood vessels to dilate, which leads to raised welts on your dogs skin.

The most common allergens causing dog hives include:

• Insect bite or sting, or ingesting an insect (photo recommendation: dog playing with bee)
• Vaccinations
• Acute allergic reactions to medications (chemotherapy, vitamin K, antibiotics)
• Food allergies
• Environmental allergies (grasses, trees, mold, dust mites, etc.)
• Contact allergens such as shampoos, insecticides, cleaning products
• Ingesting or skin exposure to toxic plants

Much less common causes of hives in dogs include prolonged exposure to extreme temperatures (hot or cold), strenuous exercise, parasites, or significant psychological stress.

Insect bites/stings, food, and medications are the most common causes of hives in dogs.

How are dog hives diagnosed?

As a pet parent, it can be worrisome to see these skin rashes, but luckily, for your vet to diagnose your dogs hives. Your vet will use a combination of your history and their physical examination findings.

Its essential to think about anything new your dog may have been exposed to. Did you see them playing with a bee? Were they recently vaccinated? Did they start a new medication or a new food? During the physical exam, your veterinarian will look at your dogs skin to evaluate hives and where the hives are located.

If your veterinarian is having trouble diagnosing your dogs hives or the reason for their hives, they may perform additional diagnostics, such as blood work, skin cytology, skin scrapings, or fecal analysis.

How to treat & get rid of dog hives?

Treatment for hives in dogs can be simple or more extensive, depending on the cause, severity, and duration of the allergic reaction.

To get your dog quick relief from the swelling and itchiness related to hives, your veterinarian will usually administer an injection of diphenhydramine (an antihistamine) and a corticosteroid. Once your dog is feeling better and discharged from the hospital, your veterinarian may also recommend that you continue giving your dog Benadryl two to three times a day at home for a couple of days.

To prevent hives from reoccurring, you need to understand what caused them in the first place so that you can avoid the allergen in the future. If there is no apparent cause for your dogs hives (such as insect bite, medication, or vaccinations), it may be more challenging to understand how to prevent hives in the future. Environmental and dietary allergies are two possible causes of hives that may require further diagnostics and treatment.

Environmental allergies

If your dog has recurrent hives or has other signs of allergies, your veterinarian may recommend testing for environmental allergies with serum allergy testing or intradermal allergy testing. With these results, your veterinarian can create a plan to desensitize your dog to these allergies with allergen-specific immunotherapy.

If you determine that you cannot eliminate the allergens in your dogs environment or pursue allergen-specific immunotherapy treatment, your veterinarian may recommend:

• Giving your dog daily antihistamines (such as Benadryl, zyrtec, or hydroxyzine)
• Giving your dog other prescription-strength allergy medications such as apoquel or cytopoint
• Starting daily skin health supplements, such as omega-three fatty acids.
• Frequently bathing your dog with medicated high-quality shampoo

Food allergies

Allergies that stem from food can also cause recurrent episodes of hives in dogs. The most common cause of allergies in dogs include chicken, beef, dairy, and egg 2. Recurrent episodes of hives can also be related to dietary allergies. To diagnose a food allergy, your veterinarian may recommend a diet trial for 6-8 weeks with a prescription food or an over-the-counter diet with a different protein source, like fish or venison. If your dog responds positively to a food trial, you can continue the special diet long term.

Are dog hives dangerous?

Dog hives are rarely life-threatening. However, there are a few less common situations where hives can affect your dogs breathing and become dangerous.

• Hives in the face, neck, or throat can cause severe swelling that impacts breathing, which can become life-threatening.
• The presence of hives anywhere may indicate your dog is having or about to have an anaphylactic reaction, which causes constriction of airways and difficulty breathing. 3 Besides hives, other signs of anaphylaxis include vomiting, diarrhea, facial swelling, drooling, blue gum color, and collapse.

If you notice that your dog has hives, pay particular attention to how they are breathing and for any other concerning changes in their behavior. If you are concerned your dog may be having severe allergic reactions, take them to the emergency room immediately to rule out a medical emergency.

At-home remedies for dog hives

If possible, take your dog to the veterinarian if you notice they have hives, especially if this is a first-time problem. If your dog chronically or intermittently has hives and the issue has previously been discussed with a veterinarian, some at-home remedies may help relieve the allergic reaction.

• If the hives are not affecting your dogs face, neck, throat, or ability to swallow, you can administer Benadryl by mouth. Always discuss if this is appropriate for your dog with your veterinarian first and receive instructions about dosage and frequency.
• If the hives were caused by a contact allergen (such as grasses/trees or chemicals) or insect bites you can help relieve itchiness by bathing with a gentle oatmeal-based dog shampoo can help your dog feel more comfortable.
• Apply a cold compress to the hives or the most severely affected areas of your dogs skin. Be careful never to apply a cold compress for more than 10 minutes at one time, and always wrap the ice or cold object in a towel before applying it to your dogs skin.

Cold-Induced Urticaria in Dogs

While somewhat uncommon, dogs occasionally develop a condition known as urticaria, characterized by numerous itchy hives. Many different things can bring about the hives, and sometimes cold temperatures can induce urticaria. Urticaria is not limited to dogs, and it can afflict all domestic animals as well as humans. Fortunately, the condition is rarely serious, and several treatments are possible. Often, urticaria disappears without treatment of any kind.

Double-Checking the Diagnosis

Upon discovering that your dog has the wheals or hives associated with urticaria, take him to the vet to confirm the diagnosis. Your vet can verify urticaria simply enough, but tests are often necessary to determine the cause. Fortunately, the test for cold-induced urticaria is simple -- an ice cube is held against the skin for up to 15 minutes. The appearance of hives indicates cold-induced urticaria.

Typical Treatments

Veterinarians often attempt to treat urticaria by eliminating contact with the symptom-inducing stimuli -- in this case, exposure to cold temperatures. Doggy outerwear may reduce the exposure enough to stop the symptoms; if not, you may have to limit your pups time outside in cold temperatures. Alternatively, your veterinarian may prescribe antihistamines or steroids to help alleviate the hives.

Self-Resolving

In many cases, urticaria resolves without treatment. According to Veterinary Allergy, most cases of urticaria are transient, and last less than 48 hours. Sometimes, this happens because your dogs body stops reacting to the cold in this way. In temperate or subtropical climates, the condition many resolve with the arrival of spring.

Danger Signs

If the hives were caused by an insect sting, rather than exposure to the cold, it is possible that your dog will suffer from anaphylaxis, which can be life threatening. Anaphylaxis may cause the lining of your dogs airways to swell, cutting off his oxygen supply. If your pet displays signs that he is having trouble breathing or swallowing, contact your veterinarian immediately.

Other Causes of Urticaria

In addition to cold temperatures, a variety of stimuli can cause urticaria. Toxic plants and stinging insects can cause animals to develop hives, as can chemical exposures and medications. Additionally, exposure to high temperatures or pressure can cause the condition. The Merck Veterinary Manual for states that stress, exercise and genetic factors may also cause urticaria. Some short-haired dog breeds are at increased risk of suffering from dermographism, a condition in which they exhibit linear hives in response to pressure. Vaccinations can also cause urticaria. In such cases, the vaccination schedule and procedure should be adjusted under the direction of your veterinarian.

One of the mild allergic reactions that dogs experience is dog hives. Uncommon, but it can lead to unpleasant complications for your pooch. In rare cases, hives can lead to dog anaphylaxis, which can be life-threatening.

Like more major issues such as ticks, fleas, and other pesky parasites, its best to deal with them to minimize your dogs experience of itchy skin, dog rashes, and irritated skin, and maintain their high quality of life.

This article covers the basics of dog hives. Why they appear, and six effective and natural home remedies you can do to get your pooch feeling at the top of their game again.

Understanding Dog Hives

Hives (urticaria) are swollen, red, usually itchy patches of skin that tend to appear and then disappear almost as suddenly commonly.

The common causes are broad and range from insect stings/bites to medications and even dog shampoos. Toxic chemicals or plants can also be a cause, and sunlight, exercise, genetic irregularities, and friction can exacerbate the symptoms.

Identifying Dog Hives

To identify dog hives, gently locate the irritated area. If it is a dog hive, it will appear swollen and could result in swelling in your dogs face, lips, throat, or ears. Sometimes they meld together and become bigger and larger, which is more challenging to deal with.

Before Home Treatment, Try These Safety Precautions

Its vital to consult a vet for a proper diagnosis. This applies equally if you are uncertain about the nature of your dogs hives. But if your dog experiences swelling in or around the airways, this can lead to dog anaphylaxis, which can be life-threatening.

If your dog seems to be having trouble breathing or is breathing in a laboured manner, consult the vet immediately. Equally, its worth speaking to your vet to get a diagnosis specific to your dog.

Home Remedies for Treating Dog Hives

Cold Compress

A cold compress helps to alleviate swelling, irritated skin, or hives. Press an ice pack (simply crushed ice in a bag, remove air, and seal) against the area gently.

You can also use a commercial gel pack or wrap that fits around the joint or area in question. Bags of frozen vegetables like corn or peas work, too, and can be used without ordering a product.

Oatmeal Bath

An oatmeal bath is a classic and inexpensive way to remedy minor hives. Simply run a lukewarm-mildly bath, pour and mix in 1 cup of oatmeal as the tub fills, and soak your pooch gently for 10-20 minutes. Pat and dry. For smaller breeds, you can use less oatmeal (1/3 cup)

Aloe Vera Gel

Aloe vera gel is very beneficial when it comes to calming irritated skin. You can even purchase animal aloe, which is even more pet safe and less likely to cause an unwanted reaction, as with human aloe gel.

Start small to test for an allergic reaction; dont let your dog ingest it. It can be a natural remedy for skin contact, but if ingested, its toxic.

Chamomile Tea Rinse

Chamomile in hot water, cooled, and applied to your dog is another natural allergy medication that helps with dry skin, skin rash, and itching. So again, for the mild symptom, its effective.

Apple Cider Vinegar Solution

This product comes in a number of forms, commonly in a spray. This is convenient as it allows the pet owner to spray the hive area before going on walks easily. Its best with a 50/50 solution of apple cider vinegar and water.

Honey

Honey is multipurpose for dogs; it can help with insect bites, skin wounds, and allergen hotspots. Feeding your dog a teaspoon of raw honey each day is the trick.

A large dog might need a touch more, and a smaller breed a smidge less. The trick is to purchase local raw honey, which contains pollen, to help your dog acclimate to allergy season.

Monitoring Progress and Consulting the Vet

Monitor the progress of your dogs skin irritation by checking the affected area before and after applying the allergy relief solution.

With consistent care, the hive areas should start to go down. But if the issue persists or worsens, you must contact the vet for a more detailed and personal diagnosis. Guides are all well and good, but we dont know your dog personally.
