The Big Bang Theory Wiki

This dog was owned by the Cooper family.

It is first mentioned in "The Luminous Fish Effect" when Mary Cooper mentions that the sound of Sheldon's sonic death ray pissed the dog off to no end.

The dog was mentioned again in "The Porkchop Indeterminacy" when Missy Cooper told Penny that their family dog made the same noise that Rajesh Koothrappali after leaving the door of Penny's apartment.


  • It is not entirely clear what kind of dog it was and how it could live in Sheldon's family, although it is more possible that it was not a large breed, since it was shown many times in TBBT and Young Sheldon that Sheldon is afraid of big dogs.
