In the original The Wolf Man movie with Lon Chaney Jr. as Larry Talbot, the character at the end of the film gets beaten to death by his father with a silver cane. This is because a werewolf can only be killed by silver in the hands of someone who loves them.
When Larry Talbot appears again in Frankenstein Meets the Wolfman, he now has a scar from where he was beaten. I don't remember if this scar carries through to the rest of his appearances in later media, but it shows that at least at the beginning, Universal Pictures cared about the continuity of their monster movie stories.
My point?
Don't have one.
