Warp Hound

From Wikitroid, the Metroid wiki

Warp Hounds are creatures found in Metroid Prime 3: Corruption. They can teleport. They can also spit Fuel Gel. They are weak against Ice Missiles. They can also be one taped by a morph ball bomb to the belly.

They are used by the Reptilicus essentially as guard dogs. They may have been used by the Bryyonians as well.
