Most often, pet allergy is triggered by exposure to the dead flakes of skin (dander) a pet shed. Coming into physical contact with pet dander can cause contact dermatitis, or a skin rash, hives or trigger a person's asthma.
What you can do to try and prevent allergic reactions:
• Avoid contact with relevant animals
• If possible, avoid visiting homes/areas where pets live
• If exposure is likely, try taking an antihistamine beforehand and avoid touching the pet or being in the same room
• Wash hands after touching or being licked by a pet
• Damp dust as often as possible to help keep pet dander (as well as dust mites and other allergens) to a minimum
• Carpets should be cleaned using a vacuum (but it must be one with a HEPA (high efficiency particulate air) filter and wash hard floor surfaces with hot, soapy water
• Wash your hands after working with co-workers who have pets to avoid transferring any pet dander to your clothes, skin, or face
• Store personal coats and bags away from other employees who have pets
