How long does a dog allergic reaction last

Is your dog having an allergic reaction? Watch out for these warning signs

Pollen, chemical fumes, insect bites, and certain types of food are all common allergens in humans. Symptoms range from mild annoyances, such as itchy, watery eyes, to life-threatening anaphylaxis. For the most part, its easy to tell when a fellow human is suffering from an allergic reaction. But what about a dogs allergic reaction? They might not be as immediately recognizable as your seasonal allergies, but there are signs to keep an eye out for if you suspect your dog has allergies. Well tell you what to look for, what you can do to help, and give you a general idea of how long your precious pooch will have to deal with the symptoms of an allergic reaction.

How can I tell if my dog is having an allergic reaction?

Just like you, its possible for your dog to suffer from unique allergies. For brevitys sake, well cover the four most common causes of allergic reactions in dogs.

Acute allergic reactions

Unlike a chronic allergic condition, an acute allergy is a sudden response to an irritant, such as a sting or bite from an insect. There are other causes of acute allergies in dogs, but stings and bites are the most common. Swelling, itching, and vomiting are common, but dogs suffering from anaphylactic shock could experience difficulty breathing, show signs of cyanosis a bluish tint to the lips and gums caused by the lack of proper blood oxygenation and might even lose consciousness.

Food allergies

Yet another common allergy dogs suffer from, a food allergy often causes stomach upset like nausea, vomiting, and diarrhea. That being said, some dogs might develop skin conditions, begin to show signs of brittle fur, or might even suffer from the loss of fur. If your pup begins scratching at himself while suffering from gastrointestinal issues, its very possible hes allergic to something in his kibble. To determine the allergen, your dogs vet might recommend an elimination diet, or he may prescribe a formula developed for dogs with food sensitivities, such as this one from Hills Prescription Diet.

Seasonal allergies

Some people are overjoyed when spring rolls around each year. Others dread the sudden flare-up of seasonal allergies. And your dog might concur! Just like people, dogs can suffer from seasonal allergies with similar symptoms, such as puffy, watery eyes, itchy skin, ear infections, a running nose, and sneezing fits. While you should speak with your vet to make sure your dogs condition is related to seasonal allergies, if you notice him sneezing at the same time every year, thats likely the case.

Skin allergies

Just like some people have sensitive skin, so do some dogs. Whether your pooch has been exposed to an irritant from fleas, ticks, plants, chemicals, or even the detergent you use to wash your linens, skin allergies are miserable. Look for symptoms like hives, dry and flaky skin, redness of the skin, and itching. Make sure your precious pooch is on a flea and tick preventative, take precautions when growing certain types of plants and flowers, and use a gentle, fragrance-free detergent to wash any fabrics your dog comes into contact with.

What can I give my dog for an allergic reaction?

When it comes to treating your dogs allergies, look no further than your own medicine cabinet. Benadryl, a common antihistamine used to treat allergies, works as effectively in dogs as it does in humans. Thanks to the main ingredient, diphenhydramine HCI, Benadryl combats the symptoms of allergies with minimal side effects. Unfortunately, the FDA has yet to approve Benadryl for veterinary use, but vets frequently recommend the use of Benadryl in treating dogs and cats with allergies. Make sure to administer the correct dosage for your dogs weight, and speak to your vet before giving Benadryl if your pup is pregnant or suffers from hypertension, seizures, hypothyroidism, cardiovascular disease, glaucoma, or allergic lung disease.

How long will my dogs allergic reaction last?

As much as we want to give you a cut-and-dried answer, the truth is well, it depends on the allergen and the severity of your dogs reaction. If your dog is suffering from a skin allergy, you can look for the redness and irritation to last somewhere between two and three weeks. If your pup has seasonal allergies, you can expect to see symptoms for as long as the allergen is in bloom. Allergic hives generally appear within minutes of exposure to an allergen, and they can fade just as quickly. However, hives can also last up to 48 hours, so dont be overly concerned if they dont clear up right away.

Final thoughts on allergies

Allergies are as uncomfortable for dogs as they are for us. Whether your pup is suffering from an insect sting, a skin reaction, seasonal allergies, or a food allergy, we recommend taking your pup to the vet for a thorough checkup. Antihistamines can help manage symptoms, but your vet might also prescribe oral, injectable, or topical steroids to help control your dogs allergic reaction. Lastly, if your dog experiences difficulty breathing, you should take him to the emergency vet right away.

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

VEG is here to help! Check out this list of the four most common types of allergies in dogs. Each has its own causes and treatments, but understanding the categories can make a big difference in how well you recognize your dogs allergic reaction.

1. Food allergies

Your dog is usually quite the foodie! But now your pal has a sick stomach after eating certain types of food. This could be a food allergy, and the most common symptoms youll see is vomiting or diarrhea. However, food allergies may also present as skin conditions or fur loss, so be on the lookout for skin and hair problems.

2. Skin allergies

Yeesh, your pup usually does well in the great outdoors, but something is wrong. Skin allergies! Make sure your pet is on regular flea/tick preventative, which you can get through your primary veterinarian. We mention this because skin allergies in dogs can often be caused by exposure to fleas or ticks. Its also possible that plants or yard treatment chemicals are irritating your dogs skin. A skin allergy will present as:

• Hives (small, raised red bumps all over the skin)
• Itchiness
• Redness

A skin allergy for your dog can be caused by other things too. Have you tried a new detergent recently? New rug cleaner? Any of these could be the culprit, but you can likely rule them out quickly if you remove the suspected irritant from any contact with your dog.

3. Seasonal allergies

Its breezy and your dog is sneezy. If you notice your dog getting sick (ear infections, licking or chewing at their feet, sneezing, etc.) around the same time every year or notice him sneezing more often when hes been outside all day, theres a chance its seasonal allergies. Check out all of the allergy types in this blog, because its important to rule out other factors to make sure this is the case.

4. Acute allergies

Dogs who have sudden allergic reactions to irritants have acute allergies. Most commonly caused by pesky insect bites or stings, acute allergies may have other causes as well. An acute allergy will show as:

• Facial swelling
• Vomiting
• Trouble breathing and collapse in severe cases, this is an anaphylaxis reaction

Acute allergies may need immediate emergency vet treatment. Call or come in to your nearest VEG if you notice any of these signs. Our ERs are open 24/7, so call anytime and speak with a doctor who will answer your questions.

SYMPTOMS OF ALLERGIC REACTIONS IN DOGS

Now, were sure youre itchin to know about the seven allergy symptoms in dogs! Here are the most common reactions and what to do about them:

1. Itchiness and hives

Is your dog scratching a lot or have red areas of skin? These reactions are common in all types of allergies. If scratching and hives are the only symptoms you notice, you can wait a day or two before scheduling a GP vet visit. But if theyre coupled with any other symptoms, get to VEG soon. You may be tempted to give your dog allergy medication because theyre having a rough go of it, but call VEG for advice before doing so.

2. Diarrhea, vomiting, and upset stomach

If your dog has diarrhea or is vomiting, visit Veterinary Emergency Group as soon as possible so your dog can get the care he needs right away. Caution: this may be a sign of an early anaphylactic reaction.

3. Itchy ears

Though totally annoying for your dog, itchy ears usually arent a sign of anything life-threatening, and can wait for a primary care veterinary visit. However, if your pet is increasingly uncomfortable and/or starts to have any trouble walking, or your dogs head is tilted to one side, get to VEG asap for treatment.

4. Sneezing and runny nose

Your pups achoos are totes adorbs, but beware, when sneezing and/or runny nose is accompanied by fever or by any other symptoms on this list, your dog requires immediate veterinary intervention. They may be signs of seasonal allergies and could be very benign, but its important for your vet to check for the cause of your dogs allergic reaction.

5. Runny eyes

Watery, runny eyes need to be checked out by your primary care vet, even if you think theyre just due to an allergic reaction. This can also be a symptom of upper respiratory infection. Another reason for runny eyes is if there is damage to the eye itself (scratch or ulceration of the cornea). Rule out these potential issues by taking your dog to your vet to find out the real cause.

6. Frequent licking or chewing on skin

This symptom of a dog allergy kind of hides in plain sight! If your dog chews or licks his skinespecially his feetfrequently or seemingly nonstop, this is a sign hes dealing with some form of allergies. Who knew?

The problem could come from exposure to irritants in the backyard or on walks, but it may also be a symptom of food allergies in your dog. Although not an emergency, youll need to go to your primary care vet to determine how to treat it and what the underlying cause might be.

7. Swollen face

Take heed, a swollen face or snout is a sign that your dog may be headed into anaphylactic shock. Although dogs with a swollen face dont always suffer anaphylaxis, it is common. We recommend bringing your dog in to be seen by an emergency vet at VEG if there is any facial swelling. Well triage your dog immediately, and provide treatment to prevent it from getting worse. If theres enough swelling going on, it could lead to other signs such as trouble breathing, so dont wait it out.
