Your animal companion's abilities are determined as if you had three additional levels. Use: Selected Note that this feat works beyond a level 30 cap, thus giving a level 30 character an animal companion of 1 higher level bracket, which equates to a +2 animal level. This gives: +2 HD, +2 natural AC, +1 Str and +1 Dex (which may give additional AC, if Dex finishes on an Even number).
