Dog Allergies
A skin reaction resulting from an allergic response
Allergic reactions occur because the body’s immune system reacts inappropriately in response to the presence of a substance that it wrongly perceives as a threat. In order to develop an allergic response the body has to be exposed to something in order to trigger the immune response – this can be touched, inhaled, swallowed or injected – during a routine vaccination or by an insect sting. The body doesn’t react to the irritant directly, but reacts to the histamine released by cells damaged through the immune response on subsequent exposure.
