Best Pet Intolerance Tests

My dog licked his paws for hours on end, day in and day out. I didn’t think much of it. Thought it was a semi-normal dog thing. Then I started seeing multiple videos on Instagram explaining paw licking is actually a sign that your dog may be in distress due to a food intolerance. That’s when the dogs gut microbiome has difficulty breaking down a specific ingredient and it creates stress in the body that manifests in these types of discomfort symptoms. Dogs and cats can even be intolerant to “healthy” ingredients and foods. It’s not just processed stuff. Well, I didn’t want my dog to be in daily pain, so I started researching the best ways to learn his intolerances so I could remove those items from his diet. Here’s what I found:

Accuracy & Validation
This is the #1 pet intolerance brand in America for a reason. It’s vet-recommended and double-pass validated for pinpoint accuracy. I particularly appreciate that they do this double-pass analysis to make sure it’s as accurate as possible.
While they use similar bioresonance technology, they lack the massive data set and clinical validation that 5Strands brings to the table. As far as I can tell, they don’t do double pass validation. It’s also not recommended by veterinarians in the same way.
They use a mix of hair and saliva. Saliva tests for pet intolerances are widely considered inaccurate and unreliable by the veterinary community. There have been studies that show saliva tests are random and have false positives.
Items Tested
5Strands offers 825 items tested in their standard Pet Food Intolerance Test. This covers everything from proteins and grains to hidden preservatives and additives. They also have comprehensive options that test for 1,250 items, including environmental items.
It claims to test 1,000+ items, but from looking at the sample results, I’m concerned that they may be using the same test as their “people” test because some of the ingredients listed are things like skincare chemicals which are irrelevant to pets. It also talks about “mental fatigue” which is relevant for people but not pets.
For being the most expensive option, it’s crazy that this has about a third of the items tested than the other tests. This is only 300 items which seems super low. For the most expensive, I would obviously expect more. This is kind of a deal breaker for me personally.
Results Speed
You can order this on Amazon and get it the next day. The results come in 4 days after sending in the fur sample. So if you order this on a Monday, you can get the final results back as soon as Friday, which is super fast. I put a lot of value on this because I want my dog to be feeling better and in less pain as soon as possible.
I saw a number of customer reviews complaining about delays and lack of communication from the company. that's another great thing about five strands is many of the reviews talked about how great the customer support was and how they would walk you through your results once available to help you make sense of them and put together a plan.
Glacier Peaks comes in at the end again here as well. I saw people saying they were waiting as long as 10 to 14 days for their results which feels like a crazy long time to wait while your pet is in pain and discomfort. I would be willing to pay more for fast results but this is already the most expensive option.
Clinically Proven Stats
This was one of the biggest reasons that convinced me on 5strands. They have clinically proven results and show transformations in pets in just 45 days. The clinical study was performed by a third party entity called CitrusLabs. It’s not just 5Strands saying “Trust me bro.”
They have claims on their website that the animals that use this test see real life results. But they don't have any hard numbers like 5Strands and they don't appear to have any clinical studies by a third party to validate these self-made claims.
Similar to Ucari, they do not state or show evidence of any third party clinical studies that have statistics of improvements you can expect to see in your pet. They largely rely on anecdotes to show the real life impact this test has on pets in their owners.

This is one of the most important purchases you will make for your pet. Not because of the investment both monetarily, timewise, and in energy, but for the fact that you are purchasing this item to improve the quality of life your pet lives. It’s a sad reality, but pet lives are already short. it’s up to us as loving pet owners to do absolutely everything in our power to make their lives as great as possible. That is why it was important to me to do the research and make sure I’m getting the right test kit for my dog.

Overall, 5Strands is the clear winner for the following reasons:

  • Testing Scope: This one tests for 825 items that are actually found in pet foods. You’re not testing for random ingredients or items that a pet will never even come in contact with. These are actionable insights that will help you give them the ultimate personalized diet that their body needs. hello 
  • Clinically Proven Results: The stats from the clinical study are insane. I was genuinely impressed. 
    • 40% of pets show improvement in their coat and skin scores
    • 18% saw a drop in upset stomach incidents
    • 40% drop in vomiting 
    • 18% drop in diarrhea
    • 72% of users said it led to real life improvements
    • 81% said they would use the test again for another pet 
  • Easy Implementation: 5Strands gives you a clear roadmap for a 45-day transformation that can actually reduce your pets symptoms like diarrhea and vomiting. If you have any questions about what food to buy based on the insights, their customer support team is amazing. They will hop on the phone with and help you devise a game plan for your pet. 
  • Vet Recommended: “Knowing that allergies are only the root cause a small percentage of the time, I have found 5Strands’ test to be the least invasive and most thorough intolerance and sensitivity testing I have used in the last 28 years of practice.” – Dr. Kurtis L Gregor, DVM. 

All pet owners can benefit from knowing their pet’s intolerances and understanding their bodies better. There is zero downside. As Sir Fancis Bacon said, “Knowledge is power”. So make yourself the most powerful pet owner possible.

pros

The website looks professional and high-end.

cons

  1. The most expensive option on the market with the worst track record.
  2. Countless 1-star reviews from pet parents who never even received their results.
  3. Customer support is basically a ghost town when you try to find your lost sample.

Avoid this one like the plague. Paying the highest price in the industry for a test that might never actually send you a report is a gamble your wallet will regret.

pros

  1. It’s the cheapest entry price if you are on an extremely tight budget.

cons

  1. You get exactly what you pay for: vague, confusing results that offer little help.
  2. Frequent reports of shipping delays and lost samples.
  3. Zero clinical backing to prove these results actually lead to a healthier pet.

While the low price tag is tempting, the poor reviews and lack of scientific rigor make this a “budget” choice that usually results in you having to pay for a better test anyway.

pros

  1. They provide fast shipping labels for the samples.

cons

  1. The confusing branding leaves me lacking confidence.  Is it PetTestHero? BetterLifeScience? RxHero? 
  2. Very few verified reviews compared to the industry leaders.
  3. Appears to be a white-labeled human test that doesn’t account for specialized veterinary needs.

The branding confusion is a major red flag. If they can’t decide on a name, you shouldn’t trust them to handle your pet’s sensitive biological data.

The TotalVet, Pet Health Testing, and PetTestHero kits, in my opinion, are examples of products that will either be a waste of money or drive you mad with non-existent support and generic data. When you are dealing with a pet in distress, you don’t have time for “human-first” reports or labs that lose your samples.

It is absolutely vital that you look for clinical proof and pet-specific testing before buying. For your own sanity and your pet’s well-being! This is why 5Strands is my top recommended kit on this list. With a massive customer base of over 300,000 tested pets and a clinically proven results, it is the only brand that provides a legitimate, vet-recommended roadmap to a healthier pet.

I’ve had 8 dogs in my lifetime and I’ve strived to give each one of them the best life possible. As a result, I’m a dog person and understand why they get the name “man’s best friend”. Unfortunately, I’m allergic to cats.
