The remaining grooming teams compete in two brand-new challenges on the next episode of “Pooch Perfect,” This week’s Immunity Puppertunity is the glow in the bark challenge, where groomers must give their dogs a glow-up under the blacklight. Then, teams must bring out their best glitz and glam for the pet gala-themed Ultimutt Challenge. After each pooch shows off their star-studded groom on the dogwalk, judges must bid fur-well to one team.
