5 Strands Dog Intolerance & Sensitivity Test Reviews — At A Glance
Our Verdict
Product Description: 5Strands offers at-home intolerance and sensitivity testing for dogs, cats, and people, with tests covering food, environmental factors, and wellness-related categories.
Our Verdict & Summary
5Strands offers a convenient, non-invasive way to explore possible food and environmental sensitivities using only a small hair sample. What stood out in our review is how simple the process is and how broadly the test screens potential triggers without requiring a blood draw or veterinary visit. However, 5Strands uses bioresonance technology and is designed to assess intolerances or sensitivities rather than diagnose allergies.
For that reason, we think the results are best treated as possible leads to investigate—not definitive proof that a specific ingredient or environmental factor is causing your dog’s symptoms. The non-invasive collection process and broad list of tested items are genuine advantages, particularly for owners looking for an easy at-home starting point.
It won’t be the right fit for every dog—especially one with persistent itching, recurring ear or skin infections, gastrointestinal problems, or suspected true allergies that warrant veterinary diagnosis.
Who It’s For ▼
This test is best for owners who want an easy starting point for investigating possible sensitivities and understand that the findings should be interpreted alongside their dog’s symptoms and veterinary advice.
What Makes It Unique ▼
5Strands stands out for its at-home, hair-only collection method and ability to screen a broad range of food and environmental items without invasive testing.
Downsides & Improvements ▼
The biggest drawback is that hair-based sensitivity testing lacks strong clinical validation, so we’d like to see more independent research demonstrating that 5Strands’ results are accurate and repeatable.
Bottom Line ▼
5Strands is an accessible exploratory tool, but we wouldn’t rely on it alone to diagnose a food or environmental allergy. Veterinary guidelines still favor a controlled elimination diet when investigating suspected food allergies. Used with realistic expectations, 5Strands may help owners identify areas worth discussing or testing further with their veterinarian.

Who Is 5Strands?
Origin & Mission5Strands was founded in 2017 by a team that included Lisa Blaurock, Austin Collins, and Ethan Steed with the goal of making intolerance testing more accessible. The company offers at-home assessments for people and pets using hair samples and frequency-based technology to evaluate food intolerances, environmental sensitivities, and nutritional imbalances rather than diagnose allergies or disease.
“We wanted to make intolerance testing affordable and accessible for
every family, because everyone deserves to understand their body’s
unique needs.”

What Is A 5Strands Dog Intolerance & Sensitivity Test?
A 5Strands Dog Intolerance & Sensitivity Test is an at-home hair-based assessment that helps dog owners identify potential sensitivities and intolerances to various substances. Although commonly called an allergy test, 5Strands does not diagnose true allergies or other medical conditions. Its non-invasive test kits are intended to provide informational insights that dog owners can use when considering changes to their pet’s diet or lifestyle.
How Do 5Strands Dog Intolerance & Sensitivity Tests Work?
5Strands uses Bioresonance Technology to test your dog’s hair sample to determine whether they’ve got imbalances or intolerances to food, environmental agents, common household products, nutritional items, raw food, metals, minerals, and other items. Each test only requires 10-15 hair strands to provide accurate results. Compared to other tests (blood and prick), 5Strand tests are a pain-free procedure.
What Is Bioresonance Technology?
5Strands uses bioresonance, a frequency-based approach based on the concept that biological materials have electromagnetic frequency patterns that can be measured and compared. The company uses this technology to identify frequency responses that it interprets as potential intolerances or imbalances.
Here is how 5Strand’s Bioresonance sample analysis works according to their website:
5Strands uses Bioresonance technology to test the hair sample and obtain the results. Bioresonance technology is a safe, non-invasive form of assessment for energetic alignments in the human body. Bioresonance works by scanning a hair sample to create a profile of the energies that radiate from a person or pet. This is called their energetic blueprint or profile. With this created profile, it can now be compared to all of the energetic profiles of all of the other items we test for. If the created profile from the hair sample does not harmonize with the items tested, the energy is distorted and the intolerance or imbalance is detected. The stronger the distortion, the higher the intolerance or imbalance.
5Strands.com
It’s worth noting that bio-resonance technology is not a scientifically proven method of determining allergies and other health issues. But it is used in holistic medicine (and holistic veterinary medicine), and several anecdotal cases support its results. 5Strands states, “Testing results should not be compared to traditional blood or saliva allergy test results.”

Learn how the 5Strands pet intolerance & sensitivity test works.
What Kind of Allergies Does 5Strands Test For: Intolerances or Allergies?
5Strands tests for food intolerances and sensitivities, not food allergies.
A food intolerance or sensitivity is generally a non-immune adverse reaction to food and may involve digestive, metabolic, or other mechanisms. When a dog has a true food allergy, its immune system reacts to a dietary component. These reactions may be IgE-mediated or involve other immune mechanisms and can cause symptoms such as itching, recurring skin or ear problems, and gastrointestinal signs. Because symptoms can overlap, a 5Strands result should not be considered confirmation that a dog has a food allergy.

5Strands Pet Food Intolerance Test Benefits
Here are the main reasons to try the 5Strands pet food intolerance test.
Testing your dog for allergies allows you to develop a specific prevention plan, whether it is dietary or seasonal (change your environment to eliminate harmful allergens), and to seek specific treatment.
5Strands pet intolerance test is not intended to diagnose but is a screening tool to guide you through the food elimination diet process. It can save you time and money you could have wasted trying multiple prescription diets. You should share the results with your veterinarian and get approval before making any dietary manipulations in your pet’s diet.
Our Tester & Judge
To evaluate the 5Strands pet intolerance test under real-world conditions, we tested it with our dog, Bandit. We used the kit from start to finish, observing the hair-sample collection process, turnaround time, ease of use, and clarity of the results before moving into a deeper analysis of the testing method and report.

Our Dog’s Experience With 5Strands Dog Intolerance & Sensitivity Test
A breakdown of our dog’s experience with 5Strands:
Day 1
When our testing kit arrived, we liked that the instructions were easy to follow. This made the whole process quick and convenient. It took us about 5 minutes to complete all the steps.
Week 1–2
A little after a week, we received our test results. We were notified via email, and we were able to download them.
Results & How To Use Them
The results came as three email attachments.
The results are color-coded. Red represents foods that should be avoided, yellow represents foods that should be avoided or reduced as much as possible, and green foods should be consumed in limited amounts.
You should consult with your veterinarian. They can provide professional insight into the significance of the identified intolerance and help you understand its potential impact on your dog’s health.
It’s recommended to consider implementing an elimination diet based on the identified intolerances. This involves removing the suspected allergens from your dog’s diet for a certain period and monitoring for improvements in their symptoms. Reintroduce the eliminated ingredients one at a time to observe any adverse reactions and narrow down the specific triggers. If you notice symptoms after reintroducing the item into your pet’s diet or environment, it is advisable to remove it from your pet’s diet. However, if your dog shows no adverse reactions, you can continue to include it in moderate amounts.
By following these guidelines, you can lessen or eliminate the unwanted symptoms they are experiencing. The elimination diet will also let you test the accuracy of your results.

5Strands Pros & Cons
- Useful for narrowing down possible ingredients or exposures when the cause of recurring symptoms is unclear
- Easy to compare flagged ingredients against dog food labels, treats, toppers, and supplements
- Can support a more organized elimination process instead of removing ingredients at random
- Provides specific foods or environmental exposures that owners can discuss with their veterinarian or veterinary nutritionist
- Different test options and price points allow owners to choose a testing scope that matches their concerns and budget
- May help owners exploring recurring itching, digestive upset, or other unexplained issues identify patterns worth investigating
- Written results provide a reference owners can revisit when comparing foods, changing diets, or discussing symptoms with a veterinarian
- Hair-based bioresonance testing has not been established as a reliable veterinary diagnostic method, so results should not be treated as proof of an allergy or intolerance
- Removing every flagged ingredient could make a dog’s diet unnecessarily restrictive or nutritionally unbalanced without professional guidance
- The test cannot identify the medical cause of symptoms, which means relying on the report alone could delay diagnosis of an underlying condition
- Flagged foods or environmental items still require real-world confirmation through symptoms, diet history, controlled elimination, and veterinary evaluation
What Customers Think About 5Strands Dog Intolerance & Sensitivity Test
Here is what real verified customers had to say about this 5Strands dog intolerance & sensitivity test.
5Strands Positive Reviews
We have to highlight that Amazon customer reviews are positive. We found that a “top contributor” for Amazon Pets left a review stating how she had tried multiple foods, and nothing seemed to work. She even discovered that peanut butter was causing her dog’s allergies, and ironically enough, all her pup’s treats had peanut butter in them. She also notes that it’s also worth trying and not jump to conclusions even when your vet says so. Amazon
“This is an expensive and fast way to see what might be causing your dog’s itchy skin and paw licking. I thought I was feeding my dog a clean and neutral diet of beef, only to learn that the organs were a major irritant for him. I’ve switched his protein, and after just a few days, I could tell the difference in how much he licks and scratches.” Tiffany Fraley 4/29/2021
5Strands Negative Reviews
As far as negative reviews, we have pet parents who report their test did not work for their pets. Comments like bio-resonance testing for allergies are not reliable, it only tests for intolerances, and that instructions are vague are some of the not-so-positive comments.
Overall, the 5Strands Pet Food Intolerance Test has excellent customer reviews, averaging 4.3 out of 5 when looking at their website and Amazon rating reviews.

Frequently Asked Questions
Is 5Strands Dog Intolerance & Sensitivity Test Worth It?
At-home sensitivity testing can be appealing for dog owners trying to make sense of recurring itching, digestive issues, ear problems, or other unexplained symptoms. Our consensus is that the 5Strands Dog Intolerance & Sensitivity Test can be worth trying as an exploratory tool, but its results should not be treated as a medical diagnosis. The test is easy to use, requires only a small hair sample, and can screen a broad range of food and environmental items that may give owners useful starting points for further investigation. However, because 5Strands relies on bioresonance rather than clinically established allergy diagnostics, we recommend confirming any suspected triggers through careful elimination, reintroduction, and veterinary guidance. For dog parents who understand those limitations and want a convenient way to narrow down possible sensitivities, 5Strands can be a practical first step before making more significant dietary or environmental changes.
