In order to have an effective and successful dog bite injury claim, it is important to collect the appropriate evidence. Taking photographs of the dog and of the injuries it caused is one of the first things to do. Also, keep all of your medical records and documents pertaining to any medical treatment received for the injuries sustained from the attack. If you receive any documents or correspondence from the owner of the dog, these should also be preserved. It is also useful to write down your recollection of the events leading up to the attack and what happened after the dog bite. If you experience ongoing or long-lasting effects or injuries from the attack, document these in a journal.
