Hi, last night my 30 year old daughter was bitten by a rescue dog she is fostering. The dog had gotten a rawhide treat off the floor that was given to the other dog. My daughter tried to pull the treat out of his mouth and he bit her. His tooth went completely through her fingernail. She nearly passed out from the pain. She got in touch with her doctor this morning and they said all she needs to do is get a tetnus shot. Are they correct? Thank you for your help.
