Hi there and thanks for your question! The brief answer to this question is YES! It only takes one flea to start a flea allergy and if she is not on a month to month preventative for fleas, there is a strong chance she is still having a flea issue. Be sure she is on a good quality efficacious flea treatment and preventative product YEAR ROUND! Flea pupae can remain dormant for months in the home and an unseasonably warm day in the fall or winter could bring them back. Get a good flea preventative from your vet! Remember one flea is all it takes! hope this helps!
