From Dav Pilkey, creator of the New York Times bestselling Dog Man and Captain Underpants series, comes Hally Tosis, the adorable dog that will take your breath away!

Hally Tosis is a great family dog, but there is one rotten thing about her: her breath! It is so smelly, Hally's pet parents want to find a new home for her. The children, desperate to keep their beloved pet, try everything to rid Hally of her stinky stench. They take her for a breathtaking view, a movie that would leave her breathless, and a ride on a roller coaster that would make her lose her breath, but Hally's putrid panting persists! Only a miracle could save her now!
