In my state the only shots a dog is REQUIRED by law to have is Rabies Shot. As long as that is current, you should be fine. I think your aunt would have a hard time having someone believe that your dog was in the wrong descibing what happened with the dogs. Some people will do ANYTHING to cause a ruckus because they feed off the attention. Very sad people in the world, I know. I know a few. Good luck, PS Sorry about your mom, What an aweful women to cause you strife at this obviously hurtful time. People like that make me want to Slap the S**t out of them!
