Animal companions - more HD = more size?

[pvandyck]

If I have an 7th level druid with a wolf companion, under the druid it says the wolf would get +4 HD (and +4 natural armor, +2 Str, +2 Dex).

Now, under the entry for wolf, it says Advancement: 3 HD (Medium); 4–6 HD (Large).

1. Does this mean the wolf becomes Large?

Then under advancing monsters, it says that when something medium goes to large, it gets +8 to Str, -2 Dex, +4 Con, +2 natural armor, -1 ac size penalty, and -1 size attack penalty

2. Does the wolf get all THIS TOO?


If yes, holy cow!

The answer in both cases in no, but I don't currently have a reference handy for that.

Then under advancing monsters...

This section is for DMs who want to create especially nasty versions of the common creatures found in the MM. A particularly fierce Alpha Male, perhaps. Or a new race of Large wolf-like animals. It does not pertain to animal companions, special mounts, or even animal PCs.

So basically, as the others have already stated, "no."

No, there is text that specifies that animal companion advancement is different than monster manual HD advancement.

I don't have the text, but I believe it's in the druid section.
I think masters of the wild had something that could advance the HD of a non-animal companion creature, but that would be a cheesy work around your DM is sure to spot.

I also have a suspicion that the monster advancement should have been +4 for size increase instead of +8, but time keeps slipping by with no errata.
