Animals as Witnesses

Have you ever wondered how observant animals are? Do they understand when there is something wrong with their human companions? If they witness a crime within their household, could what they convey to an animal communicator be enough to help the authorities catch the criminal?

I know that using animals as witnesses may seem somewhat unconventional. But, they have eyes and ears just like we do. They process information that they see and hear just like we do. They only need someone to ask them what happened and be able to communicate that information back to the authorities or families that are involved in an effort to lead to crimes being solved.

We currently use animals to detect disease, to look for people in the rubble of a collapsed building, to find people that are trapped under snow after an avalanche, to search for missing people and to sniff out drugs and illegal contraband. Why not use them as witnesses as well?
