Food Intolerances in Pets are More Common Than You Think

NutriScan is a saliva test that can identify common food intolerances your dog, cat or horse may have


Dogs rarely experience true food allergies like some humans do, but instead have a high prevalence of food intolerances. Dr. Jean Dodds has developed and patented an amazing way to test your pet’s saliva to identify these intolerances.

When humans (and pets) eat food, it goes through the mouth and from there into the gastrointestinal system where it is assimilated and digested. At the same time, the foods elicit an immune response on the bowel surface, which can  be positive (tolerant) or negative and reactive (intolerant) .. There had never been a simple non-invasive way to accurately measure this surface immune response, before NutriScan.  NutriScan tests the saliva of dogs, cats or horses against common foods and quantitates the amount of species-specific IgA and IgM antibodies produced to identify any intolerances. The test currently tests for 24 foods in dogs and cats and 22 foods in horses.


The test can be ordered by anyone!

How do you know if your dog, cat or horse may have a food intolerance?

Intolerances can show up any time, so it is important to get this test periodically throughout the lifetime of the animal, such as every couple of years.

Symptoms of Food Intolerances:

  • Gas/Bloating
  • Itching
  • Licking and chewing
  • Rubbing the face on furniture or objects
  • Scooting across the floor to itch the butt
  • Chronically smelly ears
  • Intermittent diarrhea
  • Irregular bowels
  • Rumbling sounds in the gut

Why Saliva?

Dr. Dodds was reading an article about how scientists in Japan used saliva to measure stress levels of puppies that they were screening for selection as hearing impairment and seeing eye dogs. By measuring the cortisol level in their saliva, they could choose the pups exhibiting lower cortisol levels and less stress for this training.

That “eureka” moment pointed Dr. Dodds to develop a saliva test for food intolerances, and NutriScan was born.

To date, more than 17,000 NutriScans have been done on dogs and 750 on cats. Double-blind clinical trials have been performed to confirm the clinical diagnostic accuracy of the test.
