Mom's okay. Swollen and bruised and a couple stitches in each puncture.
Animal control showed up, looked at his records, gave me a copy of our local dog by laws with the dangerous dog section highlighted. Buddy could hear Xerxes going ape in my room and just raised his eyebrows at me and left.
I used to be able to have people step inside. Xerxes would bark/growl initially and then I would get him in a down/stay on his mat but can't do that anymore. As soon as I turn my back he heads toward the door barking all over again. So I take him to the room before answering the door.
Still haven't heard back from the trainer. I left another message so hopefully soon.
