Guide to Dog Allergy Testing:
How to Know Whether Your Dog is Allergic to Something

how to know if your dog is allergic to something?

In 99% of the cases, you should be able to spot common dog allergy symptoms:

  • Obsessive, constant licking
  • Itchy ears
  • Swelling
  • Sneezing
  • Biting the skin and body
  • Visible signs of skin infections
  • Inflammation
  • Wheezing

But the only certain way to find out is to perform allergy testing.

For any dog allergy testing, make sure that your dog is not taking any antihistamines or corticosteroids (at least 2 weeks before the testing), or it can affect the quality of the testing results.

In the meantime, take a look at some tips to ease the symptoms and help your dog:

https://www.youtube.com/watch?v=1xqz17j3cKs

Once you are positive your dog has allergy symptoms, perform an allergy test, and gather all the information, it's recommended to schedule a veterinary appointment.

In some cases, the allergic reaction can be eliminated by limiting the exposure to the allergen.

But some allergies in dogs, especially skin infections, may require medication.

A specialist may prescribe corticosteroids or antihistamines for dogs, especially in the case of atopic dermatitis and similar skin allergic reactions. In severe cases, an intradermal injection may be needed.

For milder conditions, just make a brand-new diet plan, with some wholesome ingredients, excluding the things your dog is allergic to.

Types of Dog Allergy Tests

1. Strand Hair Test (My Recommendation)

Out of all types of allergy testing for dogs, this allergy test provides the most extensive and reliable sample report.

Here’s how it is performed:

  1. You receive your allergy test kit (currently, there’s no better than the 5strands one)You’ll have to fill out some info regarding your dog and your address.
  2. Collect the hair. 10-15 strands should be enough (preferably, pulled out or clipped - not shed).
  3. Send the whole kit with the sample via mail. You will be provided with a pre-addressed envelope.
  4. Wait. You will receive a notification email that the test has been delivered to their laboratory, and you should wait for around 5 to 7 days.
  5. Analyze the report. Upon the arrival of the allergy testing result (again, via email), you can observe what your dog is allergic to. It’s pretty easy to follow (signaled in green, yellow, and red - according to severity).
  6. Improve your dog’s life! 🙂 Now that you know what’s causing allergies, it’s time to stop that scratching & itching forever, and reevaluate your dog's diet - perhaps go with homemade food so that you can control what your dog takes in?

2. Saliva Testing

Although I suggest strand testing, saliva tests can also be a good approach for dogs - certainly better than blood and intradermal skin allergy tests.

The procedure is quite similar to the hair allergy test, so I won’t describe saliva allergy testing in detail. You’ll receive the allergy testing kit, fill in the info, and mail it back in the pre-addressed envelope.

What differs is that you should put the cotton device in your dog’s mouth and collect the saliva sample until the swab indicates that it is enough.

3. Veterinarian (Blood Allergy Testing/Intradermal Skin Testing)

At-home dog allergy tests are much more convenient than veterinary blood allergy testing and intradermal skin testing.

It is reasonably easy to perform at-home allergy tests, and they show the same results as blood and skin test.

Not to mention that blood and intradermal skin testing is almost three times as expensive as the homemade alternative!

You should opt for a veterinary skin or blood test instead of a home-based one only if you don’t find the ingredient you’re suspicious of on the list of allergens. But that’s very unlikely, especially with the gold standard, 5Strands Test, that contains more than 350.

Veterinary Blood Tests

Veterinarian blood tests include blood samples, and - just like us, humans - our dogs are not too fond of blood extraction. No need to submit your dog to torture!

Veterinary Intradermal Skin Tests

 Intradermal skin allergy testing is very unpleasant for dogs. If you've ever had one, you'll know what I'm talking about - it involves the injection of allergens under the surface, and the same goes for dogs.

5 Best Products for Allergy Testing

1. 5Strands Pet Test - Standard Package
– The Best Test To Find The Root Cause Of Your Pet’s Allergy –

My Rating: 96/100

Food allergy is a nasty bugger. It is devastating for us dog parents to watch our beloved fur babies suffer day after day in a harsh battle with allergies.

I can understand you all feel miserable when you still keep trying to implement their already poor diet with some new ingredients only to watch them becoming once again itchy, bloated, and gassy.

The first option is to visit the veterinarian and schedule blood or intradermal skin testing, which may cost you fairly enough and, in general, is very unpleasant.

The second option is to try an at-home test kit. 5Strands 300 Test For Dogs (pets) is an affordable, stress-free (for both your dog and you) at-home test that will allow you to test your dog for over 300 common food and environmental allergens. To be more specific, you can test your dog for 255 food allergies and 100 environmental allergens. Click on this link for a full list of specific allergens.

The 5Strands allergy test uses bio-resonance technology. The machine runs electronic frequency through the sample of your pet's hair and detects imbalances in enzymes, which allow them to process substances efficiently. Sounds like science fiction, right? But it is actually rather simple to use.

The allergy testing kit includes an envelope you will use to collect 5 to 15 strands of your dog's fur and mail it back to the testing facility. After a week, they will mail your testing results with personalized guidelines for improving your pet's diet.

You can use this kit on all breeds. This test is 100% accurate, and it will detect even long-term skin allergy reactions, which are hard to detect and have a delayed onset.

Remember, this test is no substitute for making a veterinary appointment! The best thing you can after you get your dog tested is to go to your vet with the positive results and discuss them so you can come up with the best possible diet for your pet.

Pros

  • Stress-free allergy testing for your pet (unlike skin and blood tests)
  • Require only hair samples
  • 100% accurate
  • Easy to use and quick results
  • Affordable
  • Testing for over 350 allergens

Cons

  • Do not detect yeast infections

Conclusion:

If you doubt your pupper might be allergic to something, I recommend you to get it tested with the 5Strands Pet 300 Test and narrow the options if you get a positive result.

2. 5Strands Pet Metals & Minerals Test
– Great In Detecting Drug Resistance And Sensitivity –

My Rating: 92/100

Our dogs are playful little things, aren't they? They will put their paws, noses, and mouths everywhere, literally everywhere they can. Don't get me wrong - that can be very cute, but it can be extremely dangerous since some toxic substances are not obvious. Some are even airborne or found in our regular household products.

For example, did you know that toys, balls, meds, and even your dog's ceramic glazed food or water bowl can be a source of heavy metal and mineral toxicity? This also means tests will indicate positive results for any food-specific reaction.

The bad thing is that toxicity symptoms look very similar to digestive problems (fatigue, constipation, appetite loss), so you can easily overlook them. You need to pay attention to some other symptoms, such as specific skin problems, insomnia, anemia, hypertension, etc.

So why risk your pet's health when you can detect heavy metal and mineral poisoning in the early stages by using a simple home hair test by 5Strands? You can get both your dogs and cats tested for the 40 most common environmental metal and mineral allergens.

This hair strand test may detect imbalance of minerals and metals such as:

  • Aluminum
  • Arsenic
  • Zinc
  • Gold
  • Copper
  • Iron
  • Magnesium
  • Cadmium
  • Mercury
  • Phosphorus
  • Lead
  • Lithium

To get your pet tested, simply pull out 5 to 15 strands of its hair, pack it in the special envelope that came with the package, and send it to the testing facility. Their 5Strand team will screen the sample and mail you the extensive result report in between 5 and 7 days.

Keep in mind that the result will be positive just for items that exceeded the threshold set by the lab. Also, it won't indicate physical measurements of the amount of metal and minerals in the body. For that type of result, you will need to take your dog for blood or HTMA testing.

Knowing what toxins are causing the problem will help you at the veterinary appointment to make the necessary diet changes and eliminate the excess amount of allergen out of your body.

Pros

  • Detect heavy metal and mineral poisoning in the early stages
  • Accurate in detecting which mineral or metal is causing the problem
  • Detects drug resistance and sensitivity
  • Easy to use
  • Affordable
  • Fast results

Cons

  • Can't show the exact amount of allergen in the body

Conclusion:

I highly recommend you to use this test for allergy testing alongside the previous one since not all allergies are caused by food intolerance; some might be a result of exposure to heavy metals and minerals.

3. 5Strands Pet Treat Test
– Great Option To Test Intolerance On Most Common Ingredients In Commercial Pet Food –

dog allergy testing - best allergy tests that won't break the bank

My Rating: 88/100

Usually, even the slightest amount of allergen may make a mess in your pet's body, no matter the source. Of course, you may not notice this at the beginning since the allergen may need time to accumulate in the body and have delayed onset.

There are numerous cases where pets may be exposed to the allergen on a daily basis without owners even knowing it, through treats. Yes, it sounds ridiculous - but even those tiny teeny amounts of allergens over time can cause some serious allergies and allergic reactions.

Symptoms like hair loss, joint pain, inflammation, and dry skin are the best indicators of skin allergy. Inflammation causes the skin cells not to absorb nutrients properly, which inhibit certain skin & body functions. This nutrient imbalance for certain nutrients occurs since most commercial dog food and treats are of poor quality.

That is why it is always smart to test whether your dogs are positive on the most common foods that can be found in treats. This test will allow you to alternate their food or supplementation according to the allergies you've found.

5Strands Dog Nutrition dog allergy test is an at-home test that will indicate which supplement, mineral, vitamin, or any other food ingredient your pet's body is not absorbing properly. This test tests your dog for 50 most potential food allergens that can be found in popular dog treats such as Bones, Jerky, Tendons, Hoofs, etc.

Even though the limited ingredient list is the main flaw of this test, it will help you to make a decision about which brand of treats you should avoid and which you should continue to use.

Pros

  • Pain-free for your pet (unlike blood and intradermal skin tests)
  • Suitable for both dogs and cats
  • Very accurate
  • Fast results
  • Detects skin allergens and helps rule out non-allergic skin diseases

Cons

  • The narrow scope of food

Conclusion:

If your fur baby suffers from some kind of food allergy, you should keep in mind that many dog treats contain a lot of potential items that can trigger an allergic reaction.

4. 5Strands Pet Environmental Only Dog Allergy Test
– Great Option When You Know That Food Is Not The Root Of The Problem –

dog allergy testing - best allergy tests that won't break the bank

My Rating: 85/100

Just like us, humans, dogs can be allergic to invisible allergens such as pollen, fleas, dust mites in their bed, or they can be sensitive to trees, grasses, flowers... the possibilities for allergies are endless. These kinds of allergies are often mild but make their skin go itchy.

Anyhow, if you are sure your dog has no food allergy and you suspect that something from the surrounding triggers the allergic reaction, this is the solution: you can opt to test your dog at your veterinary clinic, or you can use an at-home dog test.

The 5Strands Dog Environmental Intolerance Test covers dog allergens such as grass, trees, mold, animal dander, fabrics, and cleaning materials. It test covers 100+ allergy triggers.

The environmental intolerances are classified into three levels based on the response after exposure. Level 3 allergens cause discomfort to your pet, and it is recommended to avoid exposure to them for 6 to 8 weeks until it passes through the system. Level 2 allergies may cause significant health issues and noticeable symptoms. Level 1 allergies may affect your pet's body on a cellular level.

Click on this link to find out the complete list of environmental factors tested.

This test will help you manage symptoms your dog might be experiencing. Keep in mind that intolerances do not involve the immune system, unlike allergies.

Pluck out 5 to 15 strands of your pet's hair and mail them to the testing facility in an envelope provided for that and wait 7 to 10 days to get your results back. 

The results will come with guidelines provided by the 5Strand team of experts, but it does not include the food recommendations. Then you can visit your vet with all the information you obtained and find the best possible solution.

Pros

  • Affordable
  • Reliable and accurate
  • Tests for over 100 items
  • Helps distinguish skin allergies from skin diseases
  • Fast results

Cons

  • The results do not come with food recommendations

Conclusion:

When you know that the food is not a trigger for your pup's allergic reaction, the next logical step is to check the living environment. Fleas, dust mites, and molds are common skin allergens for dogs, and this Pet Environmental Only test will help you discover if your best friend is in danger when exposed to them.

5. 5Strands Food Intolerance Test
– Find Out Which Food Ingredient Makes Your Pet’s Tummy Go Ouch –

dog allergy testing - best allergy tests that won't break the bank

My Rating: 88/100

Most dogs suffer from food allergies. There are so many allergens in food that we are not aware of; it is not unusual that you discover dogs have an allergic reaction to certain food ingredients after years and years of living together.

Food allergies usually cause an upset stomach, vomiting, nausea, skin itching, hair loss, paw biting, etc. Consider testing dogs for food allergies if you notice some of these symptoms. They will appear between several hours or even 2-3 weeks upon exposure.

Causes of the most common food allergies are proteins, peanut, wheat, corn, and dairy. Most commercial dog food contains ingredients like wheat, corn, and chicken, so it is a great idea to test your furry best friend on foods on time and prevent exposure to irritants.

The 5Strands Food Trial Test covers 250+ items that include proteins, fats, grains, veggies, fruits, seafood, additives, and preservatives. The results will show only the allergens your dog registered sensitivity to. This test does not register allergies that are caused by the immune system.

Level 3 allergies need a 6-8 week elimination period and in this period, make sure not to feed your dog with any unfamiliar food item. You can never know how they will respond to them, and you can harm their overall health. Level 2 and Level 1 allergens should not be consumed by dogs more than 23-3 times per week.

After you send the hair sample to the testing facility, you will get the result back in 7 to 10 days. 

The result will show what food items are causing allergies, so you will be able to eliminate them from the dog's diet and soothe the symptoms until they disappear.

Make sure to consult your vet after getting the result back. In most cases, after the elimination period (6-8 weeks), you can reintroduce foods to your dog one at a time in small amounts and see if the symptoms reappear.

Pros

  • Excellent test for a food trial
  • Easy to use
  • Stress-free for your dog (unlike skin and blood tests)
  • Very accurate
  • Recommended by veterinarian
  • Quick results

Cons

  • Do not register allergies caused by the immune system

Conclusion:

Food intolerance is the main trigger for allergic reactions in dogs and cats, so why not use this 5Strands Food trial and prevent unpleasant reactions by testing them in advance!
