It may be that she has a urinary infection changing her smell that has caused this behavior. I recommend a urinalysis just to be sure. Otherwise this can be a way to show dominance over her if some of the household dynamics have changed. I generally do not think of humping as a medical problem for the male dog, more as a reaction to something new in his environment.
