Dog Walker III

"BULLETS & BLOWHOLES"
Dog walker Ben Carter is shocked to discover that his mom's fiancé Alvar is an "encantado" - a shapeshifting dolphin that seduces human women and preys on their flesh. He races to Minnesota to stop their wedding, leaving demon dog Toby back in Chicago.
Ben arrives too late to stop the ceremony, but when masked gunmen invade the reception, taking hostages and demanding Alvar's head, he is isolated alone with his new aquatic stepfather. Can the dog walker make it out alive with no inugami at his side? Can a dolphin that walks like a man truly be trusted? Who are these strange and anonymous terrorists?
Lock the doors. Hide the wine. The wedding siege has begun.
