BRISTOL, Tenn. -

The changing seasons means there is a new worry pet owners need to watch out for.

Veterinarians said this winter could be bad for fleas and tickets, especially among dogs.

That means it could be an active season for tick-borne Lyme disease.

Dr. Mark Riehl said Mother Nature plays a role in the pest’s population. “The ticks may be worse this year because of the humid, hot summer built up a larger population and they'll be hatching any time now,” he said.

Vets said the best way to prevent bites is to apply flea and tick prevention products once every 30, days even when it’s cold outside. They also suggest checking your pets regularly for fleas and ticks, especially near the ears and neck.
