Flea and Tick Prevention

Fleas and ticks, pesky little things that they are, can be found year-round. Therefore, it is very important to keep your pets protected year-round. This page is dedicated to the different flea and tick preventatives we offer here at the hospital. Check out this video about the deer tick!

Simparica is a monthly chewable flea and tick treatment that is only safe for dogs. It is a liver flavored chew tablet and is available by prescription so please call ahead for a refill. We strongly recommend flea and tick control year-round.
