Review title: Defective Frontline
Product review: I have ordered Frontline for years with excellent results. This is the first time it has not worked-I have fleas all over my house that I cannot get rid of. I feel there was something defective with the product this time. I don't know if it had expired since there was no expiration date-but the product did not work. I am very upset & will not order from this seller again.
