In my long and aged time spent on the earth I have seen many lawsuits filed because a dog either bites a person or injures another dog. If there is homeowners insurance policy involved a settlement check is rapidly issued usually for $3500 miminum in the case of a dog biting a human. When a dog hurts a dog, the check covers the vet bill and any other other incurred expenses. When there is no insurance a Judge makes a similar order. Always as far as I have ever seen the dog owner is responsible for any damage done by the dog. The injured parties are not required to exercise good judgement to prevent injury. I'm no lawyer, this is just what I have seen. I am a life long dog owner and have 2 dogs over 100 lbs now. Just sayin' and junk.
