Is food to blame for your pet’s discomfort? This test will clue you in.

TL;DR: Understand your pet's potential food sensitivities with the 5Strands Pet Food Intolerance Test, which is on sale for 11% off. As of July 29, grab one for only $77.99.

Just like humans, our pets can be sensitive to certain ingredients in food. Unlike allergies, intolerances do not involve the immune system, but they can cause symptoms like upset stomach, constant scratching, hair loss, paw biting, and others.

A simple and cost-effective way to learn more about Fido's potential triggers: the 5Strands Pet Food Intolerance Test. This at-home test kit is simple and painless.

All you'll need to do is send in a hair sample. Then, after testing over 250 ingredients, including proteins, grains, vegetables, fruits, fats, seafood, additives, and preservatives, 5Strands will send you an itemized list of intolerances broken down into three levels based on the response upon exposure.

For a limited time, you can get the Pet Food Intolerance Test, which includes the hair sample collection kit, as well as a return envelope with prepaid postage, for only $77.99 (regularly $88). If you think your pet's discomfort may have environmental causes, there's a 5Strands test for that, too.
