Who Is At Risk
People who are known to have allergies are more likely to get hives. You may also be at risk to develop hives if you are on medication or if you are unknowingly exposed to things you may be allergic to, such as food or pollen. If you are already ill with an infection or a health condition, you may be more vulnerable to developing hives.
Symptoms Of Dog Hives
Red raised areas of skin called wheals, which can occur anywhere but are most commonly seen on the head, neck, back, abdomen, and legs
Excessive drooling if the mouth is swollen
Swelling , which is particularly concerning when it involves the face and respiratory system and can have severe and life-threatening consequences
What Are Dog Hives
Hives 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.

What Does It Mean When You Get Hives Out Of Nowhere
Allergic reactions often cause hives, but hives can also happen in other circumstances. Anxiety, stress, exercise, infections, and even tight clothing can cause hives. Often, people break out in hives for no apparent reason. Unless you are experiencing a severe allergic reaction, hives are usually mild.
Why Does Stress Cause Hives
While it does appear that stress alone can cause hives, the actual reason behind it is not completely clear yet. It’s believed that the hives are a result of the impact that stress has on the immune system. However, scientists do not yet understand the complete connection and more research is needed to understand the cause.
There’s also a secondary connection between stress and hives. There are people who experience hives for unknown reasons that experience stress as a result of it. This could be that they’re stressed about their physical health and why they’re getting hives, or it could be that they’re stressed about their appearance when they have hives.
How Long Do Hives Last?
This is a tough question to answer. Hives can last for just a day, or they could go on for weeks. Many times, as some of your hives are starting to go away, new ones will begin to show up. And, they can come and go over a long period of time. If you find that they continue to come back or you’ve been dealing with them consistently for several days, you may want to talk with your doctor.
You may not know how long your hives are going to be around once you get them, but there are things that you can do to prevent them.

What Are The Different Types Of Hives
Acute episodes of urticaria last for six weeks or less. Acute urticaria can be due to infections foods, medications, insect stings, blood transfusions and infections. The most common cause of hives is infections. Foods such as eggs, nuts and shellfish are common causes of urticaria. Medications such as aspirin and antibiotics also are common causes of hives. Infections causing hives include the common cold, and other viral infections. In most of these cases, when the reason for hives is removed or avoided, the hives resolve.
Chronic episodes of urticaria last more than six weeks. In most cases, the cause of chronic hives will not be identified despite testing. Half of the patients have antibodies that attack the mast cell . This triggers chemicals such as histamine to be released which causes the hives and itching. Even though hives are associated with other autoimmune conditions such as thyroid disease, treating the other condition doesnt cure the hives. Rarely, chronic urticaria has been associated with cancer. In most cases of chronic urticaria, the hives will gradually disappear over time.
Potentially Serious Causes Of Hives
- Food allergies: Some common foods that can cause allergic reactions include nuts, milk, eggs, sesame, and seafood. These reactions can sometimes be severe and cause anaphylaxis, a serious condition requiring immediate medical treatment. Anaphylaxis can cause chest tightness, hives, difficulty breathing, vomiting, and rapid heartbeat.
- Medication allergies: Antibiotics such as penicillin and sulfa drugs can cause hives, itching, wheezing, and swelling. Other common medications that can cause allergies include aspirin and ibuprofen. If the allergy is severe, it can cause anaphylaxis.
- Insect stings or bites: Insect bites can cause itching and bumps on your skin. Some stings, such as bee stings, can cause an allergic reaction that can be more serious. If you are allergic to bee venom, you may need to carry an epinephrine pen. An epinephrine pen can help decrease your symptoms if you are stung and potentially avoid an anaphylactic reaction.
- Blood transfusions: Receiving a blood transfusion can trigger an allergic reaction. If this happens, you may break out in itchy hives along with an elevated temperature, chills, and trouble breathing.

What Might Be Causing Your Unexpected Hives
Hives are a very common skin reaction that can come from some unexpected sources. Some causes you might not have thought of include:
- Colds and other viral infections. Sometimes hives can be caused by your immune system fighting colds and other viral infections. These hives often appear near the end of your cold or virus as youre starting to feel better. Theyre most common in children but can happen to anyone.

- Chronic conditions such as lupus. Hives that last for longer than 6 weeks might be a sign of an autoimmune condition such as lupus, type 1 diabetes, thyroid disease, or rheumatoid arthritis. These hives wont go away on their own. Its a good idea to make a medical appointment to get this type of hive checked out and see if a chronic condition is the cause.

Environmental stimuli may cause hives, something experts call inducible urticaria . Things like pressure on your skin, exercise, changes in your body temperature, sweating, cold, heat, water, sun exposure, and vibrations can instigate an episode of hives. You might simply be walking by a construction site or riding a train, and because of the vibrations from these things, you break out, Elmariah says. These types of hives occur less frequently than those caused by food, drugs, or infections.
Chronic hives, meanwhile, can be caused by any of the above, but they may also be a sign of a health issue or autoimmune disease. Autoimmune diseases in general have been strongly associated with the development of chronic hives, Elmariah says.

The most noticeable symptom associated with hives is the welts that appear on the skin. Welts may be red, but can also be the same color as your skin. They can be small and round, ring-shaped, or large and of random shape. Hives are itchy, and they tend to appear in batches on the affected part of the body. They can grow larger, change shape, and spread.
Hives may disappear or reappear over the course of the outbreak. Individual hives can last anywhere from half an hour to a day. Hives may turn white when pressed. Sometimes the hives may change shape or form together and create a larger, raised area.
Hives can occur in a variety of places on the body. Call 911 or seek medical attention immediately if you develop a hive outbreak around your throat or on your tongue or have trouble breathing along with hives.

Mast Cells And Histamines
Underneath the lining of the skin, gut, lungs, nose and eyes are mast cells. These are designed to kill worms and parasites.
Mast cells contain chemicals including histamine. When these are released into the skin in small amounts, they cause itching and irritation. When large amounts are released into the skin, fluid leaks out of blood vessels, resulting in swelling of the skin .
Occasionally, hives produce swelling without an itch.

This could be new foods, changing your shampoo or soap, or wearing a different type of fabric.
Once you have ruled out that your hives have been caused by something related to an allergen you should look at what other symptoms you are experiencing. If your symptoms are all related to stress, then it’s a good chance that your hives are stress induced as well. But, if you have other medical symptoms that you are experiencing as well, you may want to talk to your doctor instead of trying to self-diagnose yourself.

No matter whats happening inside your body, hives look the same. Theyre usually red or skin-colored bumps that can blanch when you press on their center. They can change shapes and move around, and may break out all over your body, Friedman says.
Fortunately, although hives can be extremely itchy, theyre not contagious, and an individual hive usually disappears within 24 hours, Elmariah says. For some people, hives can be so chronic in nature that they can be an issue for months.

How Can I Soothe My Dogs Hives
Cold compresses applied over the swollen or hives area may help relieve itching at home. In some cases, you can take antihistamines under the supervision of your veterinarian.
A hive is a lump of skin that appears suddenly on a dogs body. Redness on the skin, swelling of the face, and itching are all possible side effects. Hives are caused by allergens that are inhaled, ingested, or injected in some way. Hives can be difficult to see in dogs with thick hair coats, but they can be seen more easily on their faces and bellies. If your dog suddenly has several small lump-like bumps on its body that had not yet appeared, it is most likely suffering from hives. Because some hives disappear much faster than they appear, there is no reason to treat them all the time.
Hives can be avoided in the first place if you take precautions. If you have hives, apply a cold compress, such as ice cubes wrapped in a washcloth, to your itchy skin several times per day if the cold does not cause your hives, do so every day. You can use non-prescription anti-itch medication, such as an antihistamine or calamine lotion, to treat youritch. If your symptoms persist, you may be prescribed anti-inflammatory medication such as corticosteroids or antihistamines. If these treatments do not work, your doctor may recommend a fatty acid supplement to increase the effectiveness of steroids and antihistamines.
