How could you say no to that face? Yes, it's an adorable puppy, but these lovable eyes can be seen in fully grown adult dogs, typically perceived as "aggressive" like the one below.
Dogs are often banned from parks and all kinds of places due to their tendency for aggression. People focus on the negatives of dogs and ignore the many positive effects that dogs have on humans. Dogs have a way about them that put people at peace. They have many physically healing, as well as emotional healing, benefits. Many argue what a danger dogs are to people. And while some dogs are, they shouldn't be stereotyped as violent creatures. They bring out the best in humans, and people should take some notes from dogs; they are forgiving, easily pleased, loyal, easy companions, expressive, playful. Dogs aren't easily upset and angered, and are unlikely to attack. If they do, it is a result of defense for themselves or their owner. Some dogs have also been manipulated and trained to attack, and this is helpful to people like policeman, but the dog does not naturally act like that. Abused dogs also can bite, but only due to self-defense or painful memories.
Some of the effects that dogs have on people are:
1) Dogs create better learning environments in classrooms, and can calm stressed students. They also help in assisted living facilities, by calming the residents and helping them with everyday activities that may be difficult for them. Dogs help all people with loneliness, depression and anxiety and are a positive influence in many settings.
2) No, it's not a myth, dogs can also literally sense how a human is feeling. Dogs are more likely to try and approach a stranger who is obviously upset than a happy stranger. Dogs sense sadness, and make attempts like sitting in your lap or nuzzling your face to try and cheer you up and comfort you. Dogs can also sense fear, and will either try and protect you or grow afraid along with you. Not only that, but their great sense of smell lets them know when you're sick. Dogs have been known to detect things like cancer and heart problems before anyone else can see it. They have a very keen sense of body language too. They know if your playing favorites or not paying attention to them.
3) Even when someone is petting a dog (an unfamiliar dog or a known one) they experience a lower level of stress. People petting dogs have been found to have lower blood pressure, slower heart rate, relaxed muscles and regular breathing. A dogs effect on lowering stress levels works faster than any medical drug. Dogs have not only these short term effects, but long term effects. Dogs reduce cholesterol and improve overall health of people with unhealthy diets or smokers. People with dogs live longer due to their improved health.
4)They also help people with social problems. People who live alone, but with a dog, are less likely to have depression. A dog offers a source of affection and companionship for those who are alone. When people are out walking a dog, they are more likely to stop and greet others, due to the relaxed feeling that comes with walking a dog. Dogs somehow encourage greater social activity. Children can find encouragement in their dog when going through something tough at school. Children confide in their dog like they would a best friend. They make good listeners, and have therapeutic, comforting effects. Dogs often can change bad moods to good ones, simply by being around.
