A warning from environmental officials to pet owners: It’s coyote mating season, which means coyote-human interactions are likely to increase.

Over the weekend in Ridgefield, a coyote had to be euthanized after biting a local resident. The Department of Energy and Environmental Protection (DEEP) believed, based on initial reports, that the animal was ill.

Attacks on humans by coyotes are extremely rare, but coyotes are common in Connecticut. Officials said it’s important to understand the steps to keep yourself and your pets safe.

At the turn of the new year, you might see or hear the eastern coyote more.

“We heard about the incident in West Hartford about a year and a half ago,” said Bob Goodman, a resident of West Hartford himself.

Goodman is referring to a December 2024 coyote attack on a dog, which left the dog fighting for its life.

Goodman said protecting his dog is always a top priority.

The eastern coyote is common in Connecticut and has been reported in every town and city in the state. January marks the start of mating season for the species, so they naturally become more territorial.

“We will see a kind of behavior that people interpret to be more aggressive because coyotes are acting more boldly,” said Geoff Krukar, a wildlife biologist with DEEP.

Krukar said this aggression is often seen toward other dogs, so keeping your dog on a leash and under control when out is key.

Kurkar also recommends keeping an eye on pets outside, even in your own backyard, and even if they are only out for a moment.

“If your dog or cat is not being watched, there is an opportunity for a negative interaction with a coyote,” he said.

Small dogs are particularly vulnerable because they are seen as prey. There is coyote-preventive gear that owners can purchase for extra protection against predators.

“We bring a flashlight with us, and we scan the backyard to make sure there is no coyote lurking,” said Goodman.

For Goodman, it’s personal; he has known friends and family who have had their pets killed by coyotes. He said he would rather take an extra second to stay with his dog or check his own backyard to prevent anything tragic.

If you are alone and encounter a coyote, DEEP explains it’s best to make your presence known by making noise and then leaving the area.

It’s also around this time of year that coyotes might consider finding a den close to a home, such as under a porch or near a foundation. Krukar said you can take steps to prevent them from choosing a spot near a home, like running a radio near a den to scare them off.

Keeping coyotes away from a home can also mean securing trash and removing any food sources, as with strategies to prevent bears.
