In brief: 4 months
The available information is for cat dander, but dog is probably similar. Typically about 4 months is needed to decrease levels to below 8 microgram/gram carpet dust.
It is possible for levels to persist longer.

In brief: Hours
That's why if you are allergic to cats or dogs you should keep them out of the bedroom 100% of the time.
If that is impossible, a hepa air filter may help. Also check out other tips at www acaai.Org.
