In brief: Possibly years

Persons who are allergic to animal dander often report trouble with an apartment or a previously owned home that was contaminated with animal allergens several years prior. Through cleaning may need to include carpet removal in some situations.

In brief: Months at least

We know with cat dander that it takes at least 6 months with regular cleaning for the cat allergens levels to decrease in homes.
It is probably similar for dogs and other furred critters.
