My wife was walking our dog early this morning. There was an off leash dog that escaped from their yard. It bolted to my leashed dog and there was an altercation. My dog bit the other, and through the chaos, my wife’s finger is now broken. Her finger wasn’t broken from a bite, but she tried to break them up and now she has to see a specialist given the damage. The owner eventually came out, grabbed their dog and went inside without saying a word. What am I to do?? She’s in crazy pain and went to the hospital. The damage is bad. We don’t want anything to happen to our dog though given the fact she did bite. We are new to CT and don’t really know the laws pertaining to this situation.
