Fizzgig is the pet of Kira in The Dark Crystal. Though seemingly cute and innocent, he can bare his fangs to protect his mistress.

Fizzgig has many dog-like qualities in personality, barking at strangers (or for attention) and biting at percieved threats, but he also has unique abilities, such as rolling into a furry ball and bouncing along the ground. This seems to be his primary method of getting from place to place instead of running. He also has a fluffy raccoon-like tail and several sets of sharp, pointed, shark-like teeth.
