Paramedic dogs
Dogs are animals, generally domestic, who know and love us more than anyone. They try to take care of us whenever they can and are close to us when we have a terrible time. They do this because they are hypersensitive and feel the pain of others. We love dogs.
They have a powerful sense of smell that allows them to sniff out ailments. And they try to heal them by licking the area they think is affected. It never happened to you? Then you should probably adopt a dog. You will not regret it; they are the most tender creatures on earth.
