It’s brews you can use.

Brooklyn resident Floyd Hayes, 47, registered a pint of beer as an emotional support animal with the USA Service Dog Registration in December, according to Ale Street News.

Brooklyn Paper reports that Hayes aims to use the certification to carry his beverage of choice — like, say, a seasonal IPA — on public transit.

“I travel from upstate to Brooklyn a lot, and on the bus they say it’s a federal crime to smoke or have an alcoholic beverage unless by prior written contest, and I always wondered where you get that consent,” Hayes, a creative director originally from England, told the publication. “Not that I’m an alcoholic,” he added.

But Hayes tells The Post he simply wants to see if this method will work.

“It was really just . . . an experiment,” he says, adding that it was a light-hearted move. “I’m not trying to make light on anybody who has any emotional issues.”

Hayes took to the service dog registration website to enter his beer as an emotional support dog. He ticked off “No Training Needed” as the training status of the dog and put that it was to help with his “Social Anxiety Disorder.”

“I don’t mean it in a heady mental health manner,” the Clinton Hill resident told the Brooklyn Paper. “More if you go to a party, and want to break the ice.”

But an unidentified USA Service Dog Registration employee told the paper that Hayes wouldn’t have much luck with his goal to commute with a six pack in tow.

“He can register his beer all day long, it’s not going to get him anywhere,” she said — adding that the use of an emotional support animal on transit or in a business requires medical approval.

But so far, Hayes tells The Post, so good. While waiting for the bus at a Brooklyn stop yesterday, he says, he had a glass of beer in hand.

“I was not approached by any law enforcement,” he adds.
