A Snellville couple accused of giving their dog LSD denies the allegation, Channel 2 Action News reported.

Nicholas Modrich and Jamie Hughes, both 25, admitted taking the drug and running naked through their neighborhood along Pinehurst Road on Sunday night. But they said they did not give the drug to their dog, which was hit by a car.

"When (Modrich) went outside naked, I went chasing after him and I think that's when the dog got out," Hughes told Channel 2.

The couple adopted Oscar from an animal shelter last week, the report said. He was run over during Sunday's incident, and police told the AJC Tuesday that the dog had been euthanized.

Police said that during questioning, the couple admitted giving LSD to Oscar.

"They were tripping pretty hard," Snellville police Capt. Harold Thomas previously told the AJC.

Modrich and Hughes told Channel 2 that the acid was sprinkled on two Gummi worms that they ate.

"I guess the story got twisted because somebody said we fed him LSD. We never did that," Hughes said.

The couple faces charges of misdemeanor possession of less than an ounce of marijuana, possession of a drug-related object and public indecency, police said. Modrich also was charged with simple battery for allegedly pulling Hughes' hair.

Test results are pending for Oscar, and no charges related to the dog have been filed, police said.
