Myzery78 11-29-07, 10:31 PM	An animal companion never increases in size because of gaining HD, they advance as animal companions, not normal animals of their type.
AngelofCthulhu 11-29-07, 11:18 PM	I should have asked this originally, but, is there anything that explicitly says this? Or says that the opposite is not true?
Myzery78 11-29-07, 11:56 PM	Yeah generally if you ask a question here I'd say its implied you'd like an official source, I was just too lazy to figure out where the answer was at the time. It is answered in the FAQ, which you can download from the link below. It is in the first one listed, and this particular question is listed on page 13. And for some reason they answered the same question again on page 14... http://www.wizards.com/default.asp?x=dnd/er/20030221a

The advancement entries for creatures, and the rules for advancing monsters, refer to unusually powerful specimens that are simply tougher (and perhaps bigger) than normal for their kinds." and again: "The animal companion rules—or, for that matter, pretty much any other effect that grants a creature bonus Hit Dice— don’t use the monster improvement rules presented in Chapter 4 of the Monster Manual. The rules in Monster Manual are for creating tougher versions of existing monsters, not for increasing the statistics of creatures who gain Hit Dice. An animal’s normal advancement line has absolutely nothing to do with the benefits it gains from being an animal companion, and vice versa. A wolf animal companion doesn’t become size Large when its Hit Dice increases to 4, nor is it limited to the “normal” Hit Dice cap for wolves."
