Researchers at the University of Chicago have conducted a study and found out that owning a pet dog can make people feel less isolated. Owning other types of pets (i.e. cats, lizards, hamsters) have no effect on the matter. Professor John Cacioppo states that dogs are associated with less loneliness. Other pets on the other hand are not associated with this.
When people go out with their dog, they will tend to meet neighbours who will say “Hello.” Other people without their pet pooches will most likely just walk past without a second glance. One of the reasons is that when a dog stops to communicate with another dog, the owner will usually stop as well.
