Dog filter

The dog filter is a zoophile piece of software which places the picture of a dog on a human face. It was popularized by the smartphone app Snapchat, which recognizes faces through the front camera of a smartphone and places dog pictures on the faces. Girls who use it show they are not interested in mating with a human male.

On Snapchat specifically, if the person opens their mouth, the virtual dog sticks out its tongue.

An Snapgirl or Instagirl who uses the dog filter intends to appear cute and sweet, but in reality she appears dirty and repulsive, except to zoophiles.
