1. Any dog trained by law enforcement to detect drugs, especially marijuana, by smell. I broke out in a cold sweat when I saw them bring the pot hounds onto the bus. There's no way I'm smuggling dope through the airport—that place is crawling with pot hounds!

2. Any stray, mixed-breed dog; a mutt. A slang term specific to the islands of the West Indies, especially Grenada. Our family befriended a pot hound that kept sniffing around our garbage, eventually adopting the rascally thing as our own. This part of the island is positively crawling with pot hounds.
