Dander

Dander is a term that refers to the tiny, often microscopic, flakes of skin shed by animals with fur or feathers. For people with allergies, exposure to dander can cause a variety of symptoms, including sneezing, itching, and watery eyes.

Overview

Dander is composed of tiny, even microscopic, flecks of skin shed by cats, dogs, rodents, birds and other animals with fur or feathers. These bits of skin can cause reactions in people who are specifically allergic to these triggers.

Symptoms

People with allergies to dander may experience symptoms such as:

• Sneezing
• Itching
• Watery eyes
