When Clarissa tricks Dylan into acting wild, Hugo calls in Pest Control.
Delilah is at work at the hospital with her human companion Doctor Dave, who tells her about his personal life having to raise three children, which Delilah finds ironic. Back at the house, the Dalmatians are playing in the backyard with Dylan showing off his hiding place blueprints to Dolly for a future hide-and-seek game. When Clarissa accidentally gets splashed by the Dalmatians playing with the water hose, she resolves to rid herself of the Dalmatians once and for all. Taking one of Hugo's slippers, she tosses it over to the Dalmatians' yard and beckons Dylan to fight with it after comparing herself to him, something he finds insulting. Dylan proceeds to rip the slipper in half with Dizzy, which is witnessed by Hugo. He then falls on a thorn bush left by Clarissa, and becomes convinced that the Dalmatians attacked him.
At the hospital, Hugo yells on the phone about the Dalmatians having attacked him, though Dave and Delilah clearly see that he has a large thorn in his rear, and decide to numb him while they yank the thorn out. Before they do so, however, Delilah hears Hugo call pest control to come and take away the puppies on Dalmatian Street. Delilah yanks the thorn out, which accidentally knocks the syringe out of Doctor Dave's hand, causing him to stumble on top of it, injecting himself with the numbing serum, and making him lethargic. Delilah and a slightly unconscious Dave race down the street on an electric wheelchair with the former sending a message out to the Dalmatians that pest control is coming. The Dalmatians scramble since with the number of dogs in the house, as well as the fact that they do not have a human, the likelihood of them being taken away is immense. Delilah runs into Pearl, who agrees to aid them in keeping pest control away.
Dolly & Dylan form two teams to think of a way to handle this. Dylan's group adapt the bowl flinger to launch a boot and pie at whoever comes through the door, while Dolly's group create a human using a coat, balloon and a voice box of random phrases. As soon as Delilah and Dave arrive, the balloon head of the figure explodes, and Dave is knocked unconscious again by the boot launched at him. Using Hugo's slipper, the Dalmatians are able to awaken Doctor Dave, who is amazed at how large Delilah's family is. With Dave willing to help by acting as their human, the Dalmatians now need to cover for how many are in the house. They are able to hide the other puppies using the hide-and-seek blueprints, which Dylan was looking at earlier. Pest control arrives and sees only Dave, with Dylan, Dolly, Delilah and Dorothy as the only dogs. Convinced that it was a false alarm, pest control leaves and the dogs thank Dave by giving him a group hug.
Outside, Clarissa is angered that pest control did nothing and barks at them. Believing that she is rabid, they capture her instead while the Dimitris are seen playing on the electric wheelchair.
