They do not get an extra attack. They get 1 additional teeth and claws or crushing teeth and claws attack in the Fight phase, if they are any of the listed units.
Note, they list the THUNDERWOLF keyword, so anything with the THUNDERWOLF keyword would get 1 additional teeth and claws or crushing teeth and claws attack in the Fight phase.
