Not automatically. Just because you were bitten by a Pit Bull, German Shepard or other large dog does not mean you can automatically bring a claim against the owner of the dog. It is still necessary to show that the dog had a history of being vicious and that the owner knew or had reason to know about the dog’s prior dangerous behaviors.
Understandably, the larger or stronger the dog the more serious your injury is likely to be. Therefore, your lawyer will want to know as much detail as possible about the breed and size of the dog that bit you.
