Yes, but only to obtain specific information, such as their name, contact information, and details about their dog. However, you shouldn’t get into a long discussion with them. You could inadvertently say something that hurts your case. For example, they seem visibly upset about their dog injuring you, and as a way to make them feel better, you tell them it’s “not a big deal.” Their defense attorney could use your words against you later to minimize the severity of your injury. Let your attorney communicate with all parties involved in the case.
