The Frog-dog (Ranacanis domesticasapiens) is a reptilian creature from an unspecified planet of the the Star Wars galaxy. They are often mistaken for dumb animals, which they use to their advantage, allowing others to keep them as pets in order to exploit the abundance of food and shelter.
Despite their name and amphibious appearance, they are in fact reptiles. They have grey or blue skin, large heads, sharp teeth, bulgy eyes, a short tail, and two legs. Specifically they have front legs, but no hind legs.
Aside from freeloading off their owners, they also sneak onto ships as spies, as they're generally ignored.
