If your furry friend is constantly scratching or exhibiting signs of discomfort, an allergy test for dogs could provide relief.

There are three main options: the RAST blood test, intradermal skin testing (the gold standard), and at-home hair/saliva tests. While convenient, at-home kits lack scientific backing compared to vet-administered tests.

Identifying specific allergens through proper testing allows your vet to develop a targeted allergy management plan, potentially involving hyposensitization therapy to build tolerance.

Don’t let your pup suffer – the right allergy test for dogs can get to the root cause and pave the way for an itch-free life.

Types of Allergy Tests for Dogs

You have a few options for testing your dog’s allergies.

The intradermal allergy test is considered the gold standard, but it involves injecting small amounts of allergens into your dog’s skin and requires sedation. It’s highly reliable at identifying environmental allergens.

Blood allergy tests like RAST measure allergen-specific antibodies without sedation but have higher rates of false positives.

At-home dog allergy tests using hair or saliva samples are convenient but lack scientific backing for accuracy.

Costs vary widely depending on the test. Carefully interpret results with your vet to develop an effective allergy management plan for your furry friend.

RAST (Radioallergosorbent Test)

The RAST (Radioallergosorbent Test) is a blood test that measures allergen-specific IgE antibodies, allowing you to determine the specific allergens triggering your dog’s atopic dermatitis. This essential information enables the development of an effective allergy management plan customized to your pet’s needs.

Blood Test That Measures Allergen-specific IgE Antibodies

You can opt for a blood test that measures allergen-specific IgE antibodies. It’s known as the Radioallergosorbent Test (RAST) and involves:

1. Drawing a blood sample
2. Analyzing for IgE levels against specific allergens
3. Identifying potential triggers
4. Providing data for allergy management

This test offers convenience, as it doesn’t require sedation and can be done while your pup is on allergy meds.

Determines Specific Allergens Triggering Atopic Dermatitis

Once the RAST test identifies the specific allergens causing your dog’s atopy, you’ll know what’s triggering their itchy skin. This valuable information allows you to:

Option	Benefit
Avoid allergens	Reduce exposure, flare-ups
Allergen-specific immunotherapy	Gradually build tolerance
Antihistamines	Manage symptoms
Specialized diet	Eliminate food allergens
Frequent grooming	Remove environmental allergens

The RAST test’s allergen identification is essential for managing atopic dermatitis effectively.

Allows for Development of Allergy Management Plan

With the allergy triggers identified, you can develop a holistic management plan customized to your dog’s needs. This includes evading exposure to problematic allergens, examining medication options, and potentially pursuing hyposensitization therapy – an effective long-term solution where success rates typically range from 60-80%.

Can Be Performed While Dog is on Allergy Medications

Conveniently, you can have your dog’s RAST test done while they’re on allergy medications. This is a key advantage, as it:

• Allows testing without interrupting treatment
• Avoids medication "washout" periods
• Reduces risk of flare-ups during testing
• Guarantees accurate results despite current medications

However, be aware that RAST has a higher rate of false positives compared to intradermal skin testing. Still, its non-invasive nature and ability to test while medicated make it a popular choice for many pet owners.

Intradermal Skin Testing

Intradermal skin testing is the gold standard for diagnosing environmental allergies in dogs. It involves injecting small amounts of allergens into the skin and measuring the skin’s reaction to identify specific allergens your dog is allergic to; this test requires sedation or anesthesia but offers higher accuracy compared to the RAST blood test.

Gold Standard for Diagnosing Environmental Allergies in Dogs

The gold standard for diagnosing environmental allergies in dogs is intradermal skin testing. It involves injecting tiny amounts of suspected allergens into your pup’s skin, then observing for localized reactions. While requiring sedation, this highly accurate test identifies specific triggers for targeted allergy management and prevention plans.

Involves Injecting Small Amounts of Allergens Into the Skin

For the gold standard intradermal skin test, your vet injects tiny amounts of potential allergens just under your dog’s skin. They’ll likely need sedation or anesthesia, as these allergy injections can be uncomfortable. It’s a controlled way to observe your pup’s skin reactions, identifying specific triggers behind the itching.

Measures Skin’s Reaction to Identify Allergens

During an intradermal skin test, your vet injects tiny amounts of potential allergens just under your dog’s skin. They then closely monitor for these reactions:

1. Swelling
2. Redness
3. Hives
4. Itching

This allows them to pinpoint the specific allergens triggering your pup’s immune response—no blood sample or at-home test can provide that clarity.

Requires Sedation or Anesthesia

Intradermal skin testing requires sedation or anesthesia since it involves injecting allergens under your dog’s skin. This can be inconvenient and carries some risks, but it also offers higher accuracy compared to blood tests like RAST. Consider the pros and cons carefully with your vet to determine the best approach.

Higher Accuracy Compared to RAST

While RAST tests are convenient, intradermal skin testing offers higher accuracy in identifying your dog’s allergies. It directly measures your dog’s skin reaction to allergens, 1) minimizing false positives, 2) detecting allergy severity, 3) guiding treatment options, and 4) avoiding false negatives with environmental allergens. Although costlier initially, its precision aids effective allergy management, potentially saving you money long-term.

At-Home Dog Allergy Tests

At-home dog allergy tests allow you to collect a hair or saliva sample from your pet and mail it to a laboratory for analysis. Within a few weeks, you’ll receive the results, which should be shared with your veterinarian to develop an appropriate allergy management plan.

Collect Hair or Saliva Sample at Home

For at-home dog allergy testing, you’ll collect a hair or saliva sample using the kit provided. Hair samples are less invasive but prone to environmental contamination, while saliva offers cleaner results. Though convenient, at-home tests raise accuracy concerns compared to lab methods performed by professionals. However, the lower cost makes them an appealing option for some pet owners.

Mail Sample to Laboratory for Analysis

After collecting your dog’s hair or saliva sample at home, you’ll mail it to the laboratory for analysis. This typically involves placing the sample in a provided container and using a prepaid shipping label to send it off. The turnaround time is usually a few weeks, and the laboratory fees can range from $50 to $200, depending on the test’s thoroughness.

Results Emailed Within a Few Weeks

After mailing your dog’s hair or saliva sample, you’ll receive the analysis results via email within a few weeks. The laboratory thoroughly examines the samples, identifying potential allergens causing your furry friend’s discomfort. These at-home tests provide valuable insights, but interpreting the results requires professional expertise.

Share Results With Veterinarian

Once you receive your dog’s at-home allergy test results, it’s imperative to share them with your veterinarian. While convenient, home testing has accuracy concerns. Your vet can evaluate the results, compare costs with in-office testing, and determine if a holistic approach aligns with your dog’s needs for accurate allergy management.

Accuracy of At-Home Dog Allergy Tests

So while at-home tests relying on hair or saliva samples may seem appealing, you should be aware of their limitations:

• Currently, conventional scientific research hasn’t found these tests analyzing hair samples for intolerances to be conclusive or accurate
• There’s a higher chance of false positives and negatives compared to blood or skin testing methods
• Many holistic vets still utilize these test methods as part of their practice approach
• Results can be inconsistent and unreliable for definitively pinpointing allergens
• Inaccurate results could lead to unnecessary diet changes or allergy shots

That said, at-home tests combined with vet guidance may provide supplemental data. But for thorough allergy testing, clinical methods like RAST blood tests or intradermal skin tests are recommended for reliable diagnosis.

Symptoms of Dog Allergies

As a dog owner, you should be vigilant for common symptoms of allergies.

Such symptoms include excessive scratching, itchy and inflamed skin, constant licking or chewing, runny eyes, ear infections, hair loss, sneezing, and gastrointestinal issues like vomiting or diarrhea.

These signs can indicate an underlying allergy.

Identifying the specific triggers through proper testing is essential for effective management and relief.

Increased Scratching

One of the most noticeable signs of allergies in dogs is increased scratching. If you notice your pup can’t stop scratching, it could indicate an allergic reaction.

Identifying and managing the specific allergy triggers is essential for your dog’s comfort and well-being. Proper atopy management through allergy testing and avoidance strategies can provide relief and improve your furry friend’s quality of life.

Itchy, Red, Moist, or Scabby Skin

Another telltale sign of allergies is itchy, red, moist, or scabby skin. If your pup’s scratching reveals irritated patches, it’s likely experiencing a dermatitis flare-up. Moist dermatitis and scabby skin can worsen without proper treatment, so seek itching relief by identifying the trigger. Manage skin irritation before it escalates.

Constant Licking

If your dog is constantly licking certain areas, it may be due to allergy triggers causing skin irritation. This obsessive behavior can:

1. Lead to hair loss
2. Create hot spots or sores
3. Increase risk of infection

Consult your vet immediately, as constant licking warrants professional evaluation to identify allergy triggers and provide relief.

Itchy, Runny Eyes

Besides constant licking and scratching, you may notice your dog’s eyes looking irritated – red, watery, and itchy. This condition, known as allergic conjunctivitis, is a common sign of environmental or food allergies in dogs. Runny, itchy eyes can indicate your pup is reacting to certain airborne allergens like pollen, dust mites, or mold spores.

Itchy Ears and Ear Infections

Itchy ears and recurring ear infections are also telltale signs of allergies in dogs. You might notice them constantly shaking their head or scratching at their ears. If left untreated, ear infections can lead to ruptured eardrums and hearing loss. Allergy testing can pinpoint the trigger, allowing you to manage their environment accordingly.

Hair Loss

If your pup’s losing hair, it could signal allergies. You’ll notice thinning fur, bald patches, and red, itchy skin. This hair loss results from:

1. Constant scratching and licking irritated areas
2. Inflammation caused by allergens damaging skin
3. Secondary skin infections exacerbating hair loss

Addressing the underlying allergy is key to stopping this vicious cycle.

Sneezing

Sneezing is another common symptom that could indicate your pup has allergies. If they’re regularly sneezing, especially when exposed to certain allergens, it’s a clear sign you should look into allergy testing. Identifying the specific triggers through proper diagnosis is key for effective allergy management and prevention of more serious issues.

Vomiting And/or Diarrhea

If your pup suffers from vomiting or diarrhea, it could indicate an allergy. Food allergies often manifest as digestive issues, but environmental allergens like pollen or dust mites can also irritate the gut. Try switching to a hypoallergenic diet first to rule out food triggers. If symptoms persist, allergy testing can pinpoint the culprit – whether dietary or environmental.

Diagnosing Atopic Dermatitis

To properly diagnose atopic dermatitis in dogs, you must first rule out non-allergic skin diseases such as mange and ringworm. Once these conditions have been eliminated through appropriate testing, further investigation is necessary to pinpoint the specific allergens triggering your dog’s symptoms.

Rule Out Non-allergic Skin Diseases (e.g., Mange, Ringworm)

Before diagnosing allergic dermatitis, you must rule out non-allergic skin diseases like mange or ringworm. These conditions can mimic allergy symptoms, leading to:

• Misdiagnosis
• Ineffective treatment
• Wasted time and money

Conduct a thorough physical exam, skin scrape, and fungal culture to eliminate these false positive results from a blood sample alone.

Further Testing Needed to Determine Allergy Cause

Once non-allergic skin diseases are ruled out, you’ll need further testing to determine the allergy cause. While RAST testing can identify allergens triggering atopy, it has limitations with false positives. Consider this cost alongside at-home tests’ accuracy concerns before proceeding:

Clinical Testing	At-Home Testing	Alternative Methods
Higher accuracy	Convenience	Food trials
Vet guidance	Questionable	Elimination diets
Costly	Affordable	Environmental changes

A multi-pronged approach weighing pros and cons is often best for diagnosing atopy.

Role of Allergy Testing in Atopy

Allergy testing plays a critical role in managing atopic dermatitis in dogs. It determines the specific allergens triggering reactions, enabling the development of targeted hyposensitization therapy, which involves administering injections or liquids to build the dog’s immune tolerance over time.

Determines Specific Allergens Triggering Reactions

You’ll need to determine the specific allergens triggering your dog’s atopic dermatitis. Allergy testing through blood samples can identify these allergens, though false positives are possible. With an accurate atopy diagnosis:

1. You’ll know your dog’s triggers
2. You can develop a specific management plan
3. Hyposensitization becomes an option for long-term relief

Proper identification allows you to manage your dog’s allergies effectively.

Used for Hyposensitization Treatment

A key use of allergy testing is guiding hyposensitization treatment. This protocol builds your dog’s tolerance to allergens, managing reactions long-term. The customized immunotherapy improves quality of life:
