Michele Leonhart, the head of the Drug Enforcement Administration, has a message for those considering legalizing marijuana: Please, think of Fido.

Testifying on the DEA budget during a House Appropriations subcommittee hearing on Wednesday, Leonhart said she expected a number of things to happen after Washington and Colorado were allowed to go forward with the legalization of marijuana last year. What she didn’t anticipate was the impact on man’s best friend.

“There was just an article last week, and it was on pets. It was about the unanticipated or unexpected consequences of this, and how veterinarians now are seeing dogs come in, their pets come in, and being treated because they’ve been exposed to marijuana,” Leonhart said . . .

Leonhart was referencing a story in USA Today which noted that the effects of marijuana could make it more difficult for a dog to breathe or vomit up a product that could kill them, like butter. The USA Today article noted, however, that on its own “marijuana itself isn’t particularly harmful to dogs,” and that dogs typically won’t eat marijuana by itself.
