VACAVILLE (CBS13) — Several dogs were poisoned during a medical marijuana robbery at a Vacaville residence, authorities said.

The Vacaville Police Department said a resident on the 300 block of Temple Drive called authorities early Saturday morning to report that someone had stolen nine marijuana plants, each valued at about $3,000, from his backyard between 3:30 a.m. and 5:15 a.m.

The victim also noticed his four Boxer dogs behaving oddly, and when he searched his backyard, he found pieces of hot dogs stuffed with blue pills strewn across his property.

Investigators said the pills were apparently Tylenol PM. The dogs appear to be doing well and the owner plans to have them treated by a veterinarian for any long term effects.

Anyone with information on the crime is asked to contact police at (707) 449-5200.
