Being very sensitive to a dog's need is elementary. Dogs have feelings and like human need love respect and caring. Having owned a pet shop I understand better how to handle unexpected care issues if they arise. Have been on drugs myself I know what it means to love a dog into want somebody to take care of it if I need someone to do that. I have owned dogs for over 35 years. Dogs are very happy when they see the person who's playing with them enjoys the activity. Also the latest Research indicates that dogs are very sensitive to facial expressions more than even vocal expressions I always make it a point to show a pleasant facial expression to add or realizing that it's something that's very important to the dog
