How to keep Animal Companions from falling behind PCs?

[Psyren]

See now youre just reminding me of a problem.

Everyone needs +1-5 weapons for the bonuses but especially because they can negate mos kinds of Damage Reduction.

Greater Magic Weapon, Magic Vestments, and all the Magic Fang spells are emergency options if you have a Killer DM that withholds treasure.

For Animal Companions how do you give them something as simple as a +1 Weapon? Martial Weapon Proficiency and have an Octopus with 8 Scimitars?

Most ACs have a neck slot (see Thurbane's link above.) Put AoMF or NoNA on it; you can fluff it as a collar if that helps the visual.

You actually want to do this anyway, because a neck slot can also hold a natural armor bonus (use the MiC rules for "common item slot effects" to put both on the same item.)
