Animal Companions and Armor Spikes

[Indivar]

Well here I am again trying to cause a little trouble...

Can an animal companion trigger a magic weapon ability, such as +1 armor spikes of spell storing? Lets assume the critter has 3 int and linguistics. What do you guys think? Whats been written about this?

They can't use linguistics to activate anything. It doesn't grant an animal the ability to use a language that it doesn't have the anatomy for.

The armor spikes are a martial weapon. Without martial weapon proficiency: armor spikes the animal takes a -4 penalty to the attack roll.

PFS has said no to apes using pole arms. Animals won't use weapons but something like armor spikes (which use their body) are a bit iffier.

If you have armor spikes on, and you succeed in a grapple, the spikes inflict damage automatically. Thus, with grab comes spike damage. Also, linguistics does not grant an animal the ability to talk, I know, but it can understand a language. If the animal is attempting to use the spikes to do damage during a grapple, the -4 comes into play.

I am just looking to see if the critter could grab, inflict auto spike damage, then have the sense to activate the stored spell.
