Critters, also known as Dragon Dogs, are enemies in Spyro: A Hero's Tail, which are summoned as servants/minions of Red. They are vicious pack animals that chase and bite. Most worlds have them, and they usually come in red and blue, but there are some in Dark Mine that have frills. Their attack method is just a simple run at you and can be killed in any way (blue ones bite, and red ones attack with a tongue lash). The frilled ones however can breath fire.
- The Critters' faces greatly resemble that of the pink elder, Magnus.
