Is something bothering your pet? Find out with this hair sample test.

TL;DR: The 5Strands Pet Food and Environmental Intolerance Test is just $134.99 at the Mashable Shop as of Jan. 16.

Your dog is a good boy and deserves the world. But it’s hard to know what exactly will give him his best life.

With the 5Strands Pet Food and Environmental Intolerance Test, you can at least eliminate the things that are (possibly) bothering him. With a simple hair sample, this painless test will open your eyes to any food and environmental substances to which your pet may be intolerant. These include things you unknowingly add to the environment, like cleaning supplies or certain fabrics, natural factors like grasses or dust mites, and even basic food groups like proteins and veggies.

Intolerances aren’t the same as allergies. While allergies involve the immune system and can be life-threatening, intolerances typically take anywhere from a few hours to several days to appear and cause temporary imbalances in the body. They may not be life-threatening, but they definitely can lead to unwelcome side effects, like paw biting, scratching, upset stomach, hair loss, and more.

Once you ship out your dog’s hair sample, the folks at 5Strands will process it and send you the results via email. You’ll get a list of intolerances, broken down into three levels based on the response upon exposure. Plus, you’ll get elimination guidelines and a road map for dietary and lifestyle changes. Over 255 common pet food ingredients are tested, as well as 100 common environmental factors. The items that register a level 3 response should be eliminated based on the recommended guidelines to work toward a better quality of life. You’ll be able to clear out the possible triggers, shop better for your pet’s meals knowing what to avoid, and ultimately give them a healthier and happier environment to live in.
