This morning I was woken up by a family member telling me she had seen my neighbors dog had broken a fence panel by pushing through and bending the bottom on my fence panel and come onto my property, my dog had then chased the neighbors dogs and had followed it back in to the neighbors yard. The 2 dogs then had a fight where both pets were injured, My neighbor called me and said I had to pay the vet bill and fix the fence as the dog fight was on his property, BUT his dog had come into my yard and provoked my dog and if his dog had not broken through the fence there would not have been a way for my dog to get into the neighbors yard. I really need advise here I do not know what I am liable for and if it was my dog or his dogs fault for the incident.
