Unfortunately, dog owners are often at a serious disadvantage. Often the burden of proof is on them to prove their dog is not vicious (yes, this is legal, because dogs are property). It is often expensive to hire a lawyer, unless you can find one to take the case pro bono. Sometimes the dog is conficated and dead before one can even file and because most dogs have no monetary value, there is really nothing to sue for. Basically, the city usually holds all the cards, even if it is in the wrong. Lets hope they get a smart judge.
