Allergic to cat hair but still want a dog: what you need to know

Cat allergy versus dog allergy

Many people think that being allergic to cat hair automatically means that dogs will cause problems too, but that is not always the case. An allergy is caused by proteins that animals release through saliva, dander and urine, and these proteins differ from species to species. Even so, some people with a cat allergy also react to dogs, because certain allergens are similar. This is called cross-reactivity, and it explains why some dog owners with a known cat allergy still have symptoms now and then.

How to recognise symptoms with a dog in the house

Typical signs are sneezing, itchy eyes, a runny nose or tightness in the chest when you are near the dog. Some people develop a rash or eczema after contact. These symptoms can range from mild to really bothersome, depending on the person’s sensitivity and the amount of allergens in the house.

• Sneezing and a stuffy or runny nose
• Itchy, watery eyes
• Shortness of breath or wheezing
• Red or itchy skin after contact

Breeds that shed fewer allergens

Some dog breeds are known as 'hypoallergenic'. That does not mean they produce no allergens, but it does mean they usually shed fewer of them. Think of Poodles, the Bichon Frise or Doodles. If you are sensitive to cat hair, it is wise to spend some time with the dog first to see how your body reacts before bringing it home.

Practical tips to reduce symptoms

• Vacuum and mop regularly to remove hair and dander
• Wash your dog’s coat periodically with a mild shampoo
• Don’t let the dog sleep in the bedroom
• Use an air purifier with a HEPA filter
• Wash your hands after contact and before touching your face

An allergy does not automatically mean that a life with a dog is impossible, but good preparation and adjustments often make a big difference.

When to be extra careful

Caution is advised with severe symptoms such as shortness of breath, or allergic reactions that affect your daily life. Some people can get used to the exposure, while in others the symptoms actually get worse. If you are unsure whether a dog is compatible with your allergy, always consult a doctor or allergist for personal advice.
