Dawnguard is the expansion that adds the werewolf perk tree, without that, you can't get werewolf perks.
Yes, as part of the Companions questline in the vanilla version of the game, you will become a werewolf. However the werewolf perk tree is only added in the Dawnguard DLC.
If you mean the Werewolf and Vampire perks, these are not earned the same way as regular ones. As a Werewolf, progress towards new perks is earned by eating the hearts of slain victims. As a vampire, progress is earned by killing enemies with your claws or life drain power. So even if you started Dawnguard as Lv81 with all perk points spent, you can still max out both the Vampire and Werewolf perks. Dawnguard adds no other perks, so a Lv81 won't miss anything out in that regard either.
81 because that is the highest level and you only get 1 perk point per level
