Ways to make an animal companion bigger?

[LibraryRPGamer]

So i have a hunter in PFS and I was wondering what items and/or spells can increase the size of my crocodile animal companion. I'm looking to boost the usability of the croc's grab and death roll abilities, which have a size limit.

I know that there is the Dire Collar and the Animal Growth spell. Are there any others?

also, is there any way - feat or item - that allows magical increases to size stack?

Thanks!

Bump?

Besides the item (which is nothing more than a1/day enlarge person useable on an animal item) and the spell the only way to increase the size of an animal companion is the very select companionlist of the Mammoth Rider, which does not include the crocodile.

For PFS there is no feat or item that allows magical increases to size to stack that I know of.

If goliath druid is greenlit for PFS, you will gain Enlarge Person as a Druid spell. If you dip Goliath druid 1, your druid and hunter levels will stack for you companion, and thanks to Share Spells, you can cast enlarge person on your companion.

That's the only way I can think of.

Thanks. That's what i had thought. I suppose ii could buy multiple collars.
