First off, welcome to the board, I hope you enjoy it.
You pose an interesting question. In regards to animal control laws, I'm not aware of any regarding signage. Perhaps Somerville has a city ordnance regarding this, you'd have to check with the city. Beyond that, the issue you are referring to sounds more like a civil liability matter than a criminal issue.
I'm NOTan attorney, so I can't give legal advice. However, I can give you my opinion. I can't see how a sign could realistically open you to litigation. "Beware of Dog" could mean anything from, "If you walk on my property, my dog will tear your limbs off" to "If your allergic to fur, you might not want to come to my front door". Heck, you could post the sign even if you don't have a dog. The warning in and of itself, doesn't necessarily mean the dog is dangerous. I can't see you being liable for a sign. The DOG however is a different story. Sign or no sign, if your dog bites the mailman's ear off, you've probably got a problem. More so if YOU KNOW that your dog is prone to poor behavior.
