Story highlights Golden Retriever may have ingested marijuana after walk in park

Dog was acting lethargic, drunken

(CNN) A Colorado dog owner is asking marijuana users to be more careful with their pot.

Patty Moore called the veterinarian after her Golden Retriever, Chance, started acting strange, she told CNN affiliate KCNC

Moore said the 10-year-old dog couldn't stand to eat. "It was like her legs didn't work at all," she said.

The pet owner said she took Chance on a walk in Denver's Highlands neighborhood park a few days after the 4/20 pro-marijuana rally, according to the affiliate report.
