I think having a pet is goodbecause it can keep us company and reduce our stress and loneliness. Pets are good companionsand help put people in better moods. Hospitals even allow specially trained pets, like dogs and cats, to come and visit recovering patients. I once saw on TVa dog visiting a children’s cancer ward. When the dog entered the room, smiles immediately lit up all of their faces. The dog let the children pet is soft furand even did tricks for them. Seeing him stand there calmly wagging his tailseemed to give the children a message that everything was going to be all right. Pets seem to know when you’re upset too. Whenever I feel sad my dog comes up and sits next to me.
