Can I use the intolerance test results to change my dog's diet immediately?
Yes, the results can help you identify problematic pet foods. Your test results come complete with instructions on how to successfully adjust your dog's diet. 

How long does it take to receive the test results?
Once the laboratory receives your pet's sample, they aim to turn them around within 24-72 hours.

My dog is short haired, can he still be tested for intolerances?
Yes, we have successfully intolerance tested many short breed dogs including Staffies, Vizslas, Dalmatians, French Bulldogs, Pugs and more.


How much hair do I need to submit for pet intolerance testing?
5-7 strands of hair is all you need. 


Does the hair need to come from the root?
No, however, we suggest collecting hair from or as close to the root as possible. On pets, the hair around the neck is often an easier place to comb your sample from. Using a brush such as a Zoom Groom, or flea/nit comb can help.


What is the difference between allergies and intolerances/sensitivities in dogs?
Let's dive into the differences below:

What is food intolerance?
An intolerance is an inability to digest an item properly, whether it is a food intolerance/sensitivity or an environmental factor (a non-food intolerance). Intolerances can occur due to several reasons; the two most common are:

The body is depleted in the necessary digestive enzyme(s) for certain food and, therefore, cannot digest the item properly or efficiently take nutrients from it or a sensitivity resulting from over-consumption or over-exposure.

Many symptoms are the result of a sensitivity to a particular item. If the animal is experiencing constant slow/delayed occurring or digestive symptoms, it may suffer from an intolerance.

What is a dog food allergy?
An allergy is an immune response to what would normally be considered a harmless substance. The immune system perceives this substance to be a ‘threat’. It produces an inappropriate response, with symptoms usually starting within a few minutes, but can be as long as two hours later. 

Allergy symptoms can be more acute and serious.

What are common dog intolerance symptoms?
Stomach complaints
Mood changes
Itchy skin
Paw licking

What are common dog allergy symptoms?
Respiratory complaints
Sore eyes

How often should I test my dog for sensitivities and intolerances?
Retesting after 6-12 months can help you monitor any changes in your dog's sensitivities.

    This has been great. 
    My dog was itching, only mildly but more than he should have been, and I’m pretty certain I’ve identified the culprit straight away.

  • Human Intolerance Test Review

    Easy to use and the test results are easy to understand. 
    I already knew of a couple of my intolerances, the results for which were spot on. The items I was unaware about made a lot of sense and having cut some of these out of my diet I am already feeling the difference. Would highly recommend.
