Ever wonder what your pets do when you're not home? Tammy, DJ, Toothless and Monroe discover the answer when they meet a terrier dog named Max who enjoys his life with his owner Katie. But things change when Katie brings home a large dog named Duke who becomes a big problem for Max. Things get worse when Duke runs away, taking Max, the cubs, Toothless and Monroe with him. But more trouble arrives when they meet a group of abandoned pets led by a crazed bunny named Snowball. When Max's friends, the Justice Guardians, Team Berk and the Te Xuan Ze Adventure Crew notice the absence of Max, the cubs, Toothless and Monroe, they must travel through the city to find them.
