MINNEAPOLIS (WCCO) — Dog owners should be aware: Flea trouble is on the rise in the Twin Cities.

“Fleas can be transmitted from pet to pet, at the dog park, going to kennels, any indoor places, b/c active year round,” said Kristi Flynn, DVM, of the University of Minnesota.

The solution is simple: use a flea preventative all year long.

“We used Frontline throughout the summer. Skipped one month and he got a tick, so we figured that we’re just going to use it throughout,” said dog owner Chris Lillehei of Northeast Minneapolis.

As for ticks, experts say they’re dormant this time of year and don’t come out until it gets even warmer than the temperatures we’ve had this winter.
