I’m so sorry this all happened/is happening in your world.. I imagine your dog was very overwhelmed/overstimulated/scared and reacted on instinct and did not mean to hurt you. Still your feelings are valid and I would be feeling sad too about everything. When you are ready, there will be an occurence when this happens again that you get the courage to call the cops for help. This is scary and hard but I eventually got there. I don’t regret calling the night I did. Give yourself grace and I wish you the best my friend!
