The Dog - S1.E19

Ray brings home a stray bulldog that reminds him of the dog he had to give up as a boy due to his allergies, but his brother, Robert, bonds with the animal and the siblings then have to decide who gets to keep him. When the owner of the dog arrives at the Barones' to pick up what turns out to be her prize-winning stud, she discovers that he has been fixed and isn't worth anything to her but that he means everything to Ray and Robert.
