Since the beginning of the history of humans keeping pets, cats and dogs have been a pair of enemies, and the humans who dominate the universe do not know that the cunning cat tribe has long been ambitious and vainly trying to occupy the earth and dominate mankind. To this end, they have been passed on from generation to generation, developing various high-tech weapons, and undercover people waiting for an opportunity to launch a coup. If it weren't for the loyal dog clan who tried every means to defeat the cat clan's crazy plan every time at the most dangerous moment, I am afraid that humans would have been under the rule of the cat clan for a long time. As a result, the cat tribe regards the dog tribe as a thorn in the flesh, and is always waiting for the opportunity to put the other party to death, and get rid of it completely.
One day, a detective dog named Buddy who worked in Mrs. Brody's house was suddenly kidnapped and disappeared. Buddy’s task is very difficult and important, because Buddy’s owner, Professor Brodyis a scientist who studies human anti-dog allergies. Once Professor Brody's research is successful, it will indicate that more dogs will be favored by humans. Fortunately for the dog clan, that is definitely something that the cat clan doesn't want to see. Therefore, the three loyal dogs headed by the detective dog of Butchand guarding the neighborhood of Professor Brody's house unanimously concluded that Buddy was kidnapped by the cat family.
One month after Buddy was kidnapped, the dog family re-selected a detective dog for Professor Brody's home. This detective dog named Lu (byby the young owner Scarterwas framed by the cat family when he first arrived. Not only that, but Butch is not optimistic about Lu, the new subordinate. But in the operation of stealing and destroying Brody's latest formula time and time again planned by the cat chief Dingle, Lu defended the honor with his loyalty. After the Brody family was kidnapped during the plan of Dinge, the dog family voted at the World Dog Conference Center and decided to sacrifice the Brody family to protect the newly developed anti-allergy formula for dogs.
Lu has become a good friend of the young master Scart. Although he can't influence the decision made by the World Dog Conference Center, it still has to use its own power to rescue the owner's family from Dingo's hands. Lu enters Mason Cotton Wool Co., Ltd., the base of Dingle. At this time, Dingo was gathering troops and preparing to declare war on mankind. After Lu appeared, with the help of Butch, Sham, and Pique, he not only successfully rescued the Brody family, but also completely destroyed the cat tribe’s ambition to rule mankind.
