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?
