Northwests' dog

The Northwests' dog is the canine family pet of Preston, Mrs., and Pacifica Northwest.

History
In "Irrational Treasure," she is seen with her owners at Pioneer Day, where she appears in the family photo and lingers around them throughout the day.

Mabel Pines milks her, along with several other animals, in the opening of "Mabel's Guide to Art."
