What are Hives in Dogs?
Hives in dogs, also known as urticaria, are a skin condition characterized by the sudden onset of raised, itchy bumps on the skin. Hives can develop anywhere on a dog's body and may be accompanied by redness, swelling, and discomfort. In severe cases, hives can cause difficulty breathing or other respiratory distress, which requires immediate veterinary attention.
Signs & Symptoms of Hives in Dogs
The signs and symptoms of hives in dogs, also known as urticaria, include:
Raised, itchy bumps on the skin
Hives appear as raised bumps on the skin that may be round or irregularly shaped. They can range in size from a small pea to a large coin. The bumps may be pink, red, or white and are often surrounded by a red ring.
Swelling
In addition to raised bumps, hives can cause swelling of the face, lips, or other parts of the body. This can sometimes be severe and cause difficulty breathing or other respiratory distress, which requires immediate veterinary attention.
Itching
Hives are typically itchy and can cause your dog to scratch, lick, or bite at the affected areas. This can lead to further skin irritation and potentially secondary skin infections.
Discomfort
Hives can cause discomfort for your dog, and they may seem restless, uncomfortable, or anxious.
Sudden onset
Hives can appear suddenly, without warning, and may last for several hours to days. They can also disappear just as quickly, which can make them difficult to diagnose.
What Causes Hives in Dogs
Hives in dogs, also known as urticaria, are typically caused by an allergic reaction to a trigger. The immune system produces histamine and other chemicals in response to the allergen, which leads to the development of hives. Some common triggers of hives in dogs include:
-
Toxic Plants
-
Shampoos or Topical Agents
- Food Allergies
Certain proteins or other ingredients in a dog's diet can trigger an allergic reaction and cause hives.
- Environmental Allergies
Dogs can be allergic to pollen, dust mites, mold, or other environmental triggers, which can cause hives.
- Insect Bites or Stings
Some dogs may develop hives in response to insect bites or stings, such as those from fleas, ticks, or bees.
- Medications
Some dogs may develop hives as a side effect of certain medications, such as antibiotics or pain relievers.
- Pressure Urticaria
Pressure urticaria in dogs typically appears as raised bumps or welts on the skin that are accompanied by intense itching and redness. These bumps can be caused by anything that puts pressure on the skin, such as a tight collar or harness, or even just the pressure from lying down on a hard surface.
The exact cause of pressure urticaria in dogs is not fully understood, but it is believed to be related to an overactive immune response. In some cases, pressure urticaria may also be a sign of an underlying condition, such as an allergy or autoimmune disorder.
What Plants Cause Hives in Dogs?
There are many plants that can cause hives in dogs, either through contact or ingestion. Some common plants that are known to cause hives in dogs include:

When planning your garden or arranging indoor plants, try to avoid the plants mentioned above. It's important to note that there are many other plants that can cause hives in dogs, and some dogs may be more sensitive to certain plants than others.
Diagnosing Hives in Dogs
Diagnosing hives in dogs can be challenging, as the symptoms can be similar to those of other skin conditions. To diagnose hives in dogs, your veterinarian will typically start by performing a physical exam and taking a thorough history of your dog's symptoms. They may ask questions about your dog's diet, recent medication use, exposure to potential allergens, and any recent changes in behavior or environment.
If hives are suspected, your veterinarian may perform additional tests to help identify the underlying cause of the reaction. These tests may include:
Skin Scrapings or Biopsies
These tests can help rule out other potential causes of skin irritation, such as infections or parasites.
Blood Tests
Blood tests can help identify the presence of antibodies or other indicators of an allergic reaction.
Skin Allergy Testing
Skin allergy testing involves injecting small amounts of potential allergens into the skin to see if a reaction occurs. This can help identify specific triggers of hives in dogs.
Elimination Diet
In some cases, an elimination diet may be recommended to help identify potential food allergens.
Once the underlying cause of hives is identified, your veterinarian can develop a treatment plan tailored to your dog's specific needs. This may involve medications to manage the symptoms of hives, as well as avoidance of potential triggers and long-term management of underlying allergies.
How to Treat Hives in Dogs?
Medications
Antihistamines are medications that help block the release of histamine, which is responsible for many of the symptoms of an allergic reaction. These medications can be given orally, such as Chlorpheniramine Maleate.
Topical Preparations
- Antifungal
- Reduces inflammation
- Easy to apply to ears or skin
- Effectively treats a wide array of skin conditions
Good for wound healing, skin renewing, and itching relief, having great antibacterial and anti-inflammatory effects.
Shampoos
Chamomile is well known for its ability to reduce inflammation and irritation on human skin.
To use chamomile to soothe a dog's skin after getting hives from plants, try Chamomile shampoo.
A common home remedy for both humans and animals is coconut oil. It is a very effective option for soothing a dog's skin after developing hives from plants because of its antibacterial, antifungal, and antiviral properties.
Coconut oil contains lauric acid, which is particularly helpful in preventing and combating harmful bacteria that can lead to skin issues.
To help soothe your dog's skin as the hives subside, give them a nice chamomile and coconut oil shampoo bath to get some much-needed relief.

Omega-3
Supplements containing omega-3 fatty acids can also provide relief from pruritus (itchy skin). Studies on dogs treated with oils containing omega 3 have shown improvements in pruritus and overall coat condition. If nasty allergens cannot be avoided and your dog develops chronic skin allergies, other treatments are needed.
Final Thoughts
It's important to develop a treatment plan that is tailored to your dog's specific needs and underlying condition. In some cases, hives can be a sign of a more serious underlying condition, so prompt veterinary care is essential.
FAQs
Can a Dog Get Hives from Stress?
Yes, dogs can develop hives as a result of stress or anxiety. When a dog is stressed or anxious, their body releases a hormone called cortisol, which can affect the immune system and make them more susceptible to allergic reactions, including hives.
In addition, stress can also trigger a release of histamine, which can cause hives and other symptoms of an allergic reaction. This is known as "psychogenic urticaria," and it is often seen in dogs with anxiety or behavioral issues.
Why Does My Dog Keep Breaking Out in Hives?
Allergic reactions: Allergic reactions to food, medications, insect bites, or environmental allergens are a common cause of hives in dogs. In some cases, hives may be accompanied by other symptoms, such as itching, swelling, and respiratory distress.
Stress and anxiety
As mentioned earlier, stress and anxiety can also trigger hives in dogs. This can occur as a result of environmental changes, separation anxiety, or other emotional stressors.
Autoimmune disorders
Certain autoimmune disorders, such as lupus or pemphigus, can cause hives in dogs. These conditions occur when the immune system mistakenly attacks the dog's own body tissues, leading to inflammation and other symptoms.
Infections
Infections, such as bacterial or fungal skin infections, can also cause hives in dogs. These infections can cause an inflammatory response in the skin, leading to the development of hives.
Can Dogs Get Hives from Pants?
Yes, dogs can develop hives as a result of exposure to certain plants. Some plants are known to cause allergic reactions in dogs, which can lead to the development of hives and other symptoms.
Common plants that may cause hives in dogs include poison ivy, poison oak, poison sumac, and stinging nettles. In addition, some dogs may also be sensitive to other plants, such as certain types of grasses, trees, or flowers.
What Weeds Cause Hives in Dogs?
There are several types of weeds that can cause hives in dogs if they come into contact with them. Here are some common weeds that may cause hives in dogs:
- Burdock

What Do Hives Look Like on a Dog?
Hives on dogs usually appear as raised, red, or pink welts on the skin that may be circular or irregular in shape. They can vary in size from small dots to large patches and may be accompanied by itching or discomfort. Hives may appear on any part of the dog's body, including the face, neck, abdomen, back, and legs.
Hives can develop rapidly and may disappear within a few hours or may last for several days. In some cases, new hives may continue to appear while old ones are fading away, leading to a prolonged and uncomfortable experience for the dog.
It's important to note that hives can be a symptom of an underlying condition, such as an allergic reaction or infection, so it's important to seek veterinary care if your dog develops hives. Your veterinarian can evaluate your dog's symptoms and provide appropriate treatment to help relieve the discomfort and promote healing.
How to Treat Dog Hives at Home?
While it's always important to seek veterinary care if your dog develops hives, there are some home remedies that may help alleviate the discomfort and promote healing.
Here are two examples of home remedies for treating dog hives:
1. Oatmeal Baths
Oatmeal has anti-inflammatory properties that can help reduce itching and soothe the skin. To make an oatmeal bath, grind plain, uncooked oatmeal in a blender or food processor until it forms a fine powder. Add the oatmeal powder to warm bathwater and mix well. Soak your dog in the oatmeal bath for 10-15 minutes, then rinse with clean water and pat dry.
2. Plain Yogurt
Plain, unsweetened yogurt contains beneficial bacteria that can help reduce inflammation and boost the immune system. You can add a spoonful of plain yogurt to your dog's food or apply it directly to the affected area. If applying directly to the skin, leave the yogurt on for 10-15 minutes, then rinse with clean water and pat dry.
