Due to the mild winter, we are expecting a more difficult flea and tick season this spring.  In fact, several customers have complained that they are even seeing Ticks in February!  We have many products to suit your needs. The best we carry, at this point is the Seresto collar by Bayer.  Feedback has been excellent.  The collars are much gentler than spot on treatments and they last up to 8 months.   They repel and kill both fleas and ticks on dogs and cats.   There is also a new collar by Duravet coming on the market in March called Salvo.  Salvo is good for up to 6 months and is less costly although not rated quite as effective as the Seresto.
