Police in Colorado are searching for a someone who has been leaving drug-laced hot dogs in a yard, repeatedly sickening a family's dogs.

Investigators are looking into at least three incidents at the home in Broomfield, Colorado, since late 2025, including two that have made the dogs sick, the police department there said. Broomfield is a city of about 80,000 residents just outside Denver.

"Investigators believe the intended targets are the family’s dogs," the Broomfield Police Department said. "Based on the circumstances and pattern of the incidents, investigators believe this specific residence is being intentionally targeted."

Police don't know who is targeting the family dogs. Investigators have reviewed surveillance footage from the neighborhood and canvassed the area, but don't have any suspects, the police department said on March 30.

The first incident happened on Nov. 22, 2025, when the homeowner was doing work in her backyard and found two hot dogs. A "crystal-like" substance was found inside the hot dogs, and testing showed they contained methamphetamine, police said in a statement.
