Will human allergy to dogs fade with time?

This is the question I’ve got today from a reader. Although I’m not doctor, no allergy specialist and no dogs specialist whatsoever, I’ll try my best to give an answer.

Human allergy to dogs may fade with time, provided that the allergic person does not get in touch with dogs anymore. In some cases, it may be needed that the patient follows a desensitization treatment consisting of weekly vaccines administered for a long term period (years) followed by months or years of pause, then done again.

However, the biggest probability of an allergy evolution is to get accentuated in time, not to fade. It doesn’t matter if the allergy is to dogs, or to bee stings, or to pollen. Human allergy mechanism is the same, no matter what allergens trigger that violent reaction in our body.

I suppose that my reader who send the question has developed an allergy to her dog and she wants to know if ignoring the allergy and continuing keeping the dog in house will make the allergy symptoms diminish and disappear after several years have passed by.

This is false, so in case you are diagnosed with dogs allergy, you should seek for your doctor’s advice whenever to give up your dog or keep it.
