A veterinarian will spend six years in federal prison for using puppies to smuggle heroin.
Andres Lopez Elorez pleaded guilty last year to surgically implanting drugs into the stomachs of the animals.
Between 2004 and 2005, authorities say Elorez leased a farm in Colombia, where he secretly raised the dogs and implanted bags of liquid heroin into nine puppies– to then send to the US.
Three of the puppies died of a virus contracted after the surgery.
Elorez, who worked on behalf of Colombian drug traffickers, was a fugitive until he was arrested in Spain in 2015.
He will be deported once he completes his sentence.
