Hillary Clinton

Hillary Clinton is a female dog owned by Gayle Waters-Waters and her family, and most likely named after the U.S. politician Hillary Clinton. Gayle claims that Hillary is a "rescue dog," although Dave corrects her and says that Hillary was actually purchased from a breeder.

She is seemingly a Bichon frise, although it is also possible she could be the labradoodle mentioned in episode 1 (as those breeds look very similar).

History
Gayle is inspired to "adopt" Hillary after Dr. Bruce mentions to her that Linda recently rescued a dog, and how he so admires people who do that. (Bruce mentioning Linda in this scene was most likely a mistake, however, as it is actually Bonnie who rescued a dog, and this mix-up is never addressed in-universe.)
