Dogs assist us in so many ways, they can serve as hearing dogs, watch dogs, drugs detection drugs, etc. Dogs are trained to assist the disable in many ways.  Dogs can be trained to alert their owners to smoke alarms, sirens, doorbells and alarm clocks.  Dog training does not just include training the dog just to assist the disable, but it also includes providing help assisting finding missing people and even body recovery.  Many of us have also been entertained by dogs in the big screen, both in television shows and at the movie theaters.  Many of these dogs even made us cried, with their roles.  Dogs are amazing creatures and we are very fortunate of having them.
