I got a letter in the mail from a law group claiming my dog had bit there client and wanting me to give them my insurance information. This was out of the blue and I had no knowledge of any of this ever happening. When I called the law group asking them what had happened and what I should do they told me they cant disclose any information about the case with me. Or give any evidence that proves my dog actually bite this man and encouraged me to just give them my insurance information. Can they do this without giving me anything, and should I give them any information.
