The dog found with a man wanted on an outstanding warrant allegedly tested positive for methamphetamine and heroin.
Tustin, California, police officers went to a motel room at Key Inn & Suites to arrest 40-year-old Joshua West, KCAL reports.
His dog, Bubba, was in the room with him, along with used needles and illegal drugs.
West was on parole for drug violations, Tustin Police Lt. Robert Wright told CNN.
Animal control officers were called to the scene and found Bubba, a terrier mix, to be lethargic, according to KCAL.
Urine tests found the dog had meth and heroin in his system. It is unknown how Bubba ingested the drugs.
“This strikes me as pretty horrible,” Wright said. “This is the first time we’ve ever heard of someone reporting that an animal has been under the influence.”
Bubba is now being cared for by Orange County Animal Care. Once his detox is completed, he will be put up for adoption.
West was arrested and charged on the outstanding warrant, a parole violation, possession of drug paraphernalia, heroin and methamphetamine and animal cruelty.
