When Bobby discovers he's allergic to Ladybird, Hank must choose between the dog or his son - and it's a tough one
Bobby's recent illness has Peggy scouring the Internet in search of a diagnosis. Finally, after painful allergy tests, Bobby learns he's allergic to Ladybird. The news does not sit well with Hank - Ladybird's devoted keeper of 13 years. Bill volunteers to take in the dog, but Hank believes that Ladybird deserves better and decides to build her an elaborate doghouse.
After the emotional ribbon-cutting ceremony, Ladybird refuses to enter the doghouse. Plus, the Hill's main house is still teeming with dog dander - from the carpet to the wallpaper. Hank decides the best solution is for Bobby to move into the dander-free doghouse. Peggy is mortified, but Bobby loves having a bachelor pad. Days later, Connie and Bobby lounge on a pillow covered in dog hair, and Bobby realizes his allergy is gone. Meanwhile, Peggy feels so guilty about Bobby living in the yard that she steam cleans the entire house to make it Bobby safe. Bobby moves back, but immediately fakes an allergic attack to get back out to the yard. Back in the doghouse, he begins adopting very dog-like behavior - which starts grossing Connie out.
In a last ditch effort, Hank reluctantly lets Ladybird move in with Bill so Bobby can move back in the house. Bobby feels so guilty about Hank having to give up his beloved pooch that he fakes a miraculous recovery so that Ladybird can come home. Peggy, meanwhile, moves her office out of the water heater closet and into the spacious doghouse!
