Adding metals to animal companions claw or bite

[Fugitmori]

Is there any way to add silver/admantite/cold iron etc to the claws or teeth of an animal companion?

[BigNorseWolf]

The only way i know of is to do it for sure is to get an amulet of mighty fists up to +3

You could fireproof the animal and weapon blanch their teeth and claws, but that's only going to last one hit and the dm might say "Ermm... no"

You could get eldritch claws feat that make them count as magical and silver.
