"She's trained in gunpowder," Sgt. Matt Anderson,  her trainer, told ABC4News "You have your single base – which is a  gunpowder that is used in your older things like nozzle loaders. Flintlock is  the original old-school gunpowder. Then, what we have done to make that burn a  little hotter is add nitroglycerin, that's called double-based. That goes in  all your common firearms: your rifles, pistols, things like that. And then  we'll train gun oil."
Anderson told the news outlet that Winnie is filling a  much-needed role. People are carrying guns everywhere due to a lack of  understanding of the state's new open carry law. But Anderson pointed out there  are still many areas where people are unable to carry, such as in Charleston  County Schools.
Anderson will still do weekly training once Winnie starts  working patrol, the article reported.
