Lucky was clearly sick and in distress when police officers found him. They'd been called to arrest two men who were switching price tags at a store in Texas, and when they arrived at the scene, they also went over to check the suspects' car. That's where they discovered heroin - and a tiny puppy, around 3 months old.
The officers suspected that Lucky may have ingested and overdosed on the heroin.
"He was extremely lethargic - almost comatose - and was basically limp," Jolene DeVito, police media specialist with the Carrollton Police Department, told The Dodo.
