BOULDER, Colo. — The Boulder County Sheriff’s Department has identified the chemical that sickened at least three dogs in Gunbarrel as an ingredient commonly used in pesticides and rodent poisons.
Investigators said Friday the chemical was brodifacoum (broh-DYE’-fah-koom).
It was placed in up to eight meatballs that were first found in mid-April in a park popular with dog owners in Gunbarrel, just north of Boulder.
Tampering with dog treats in high-traffic pet areas is a trend that has also plagued cities in California. Some have been laced with Strychnine, a colorless, highly toxic chemical used as pesticide, sickening several dogs.
In Boulder, deputies are still investigating but no arrests have been made.
A reward for information now stands at more than $4,600.
