Will do people like dogs?

They love you stronger than any one can love you. They are very loyal, smart, totally dependent on you, they are like a child that fills a void, no back talk, the do as they are ask if trained properly, something to be proud of.

Dogs have been my whole life work, Canine Behaviorist, retired professional dog trainer, specialized in aggression training & basic obedience, a retired Dog Groomer that specialized in dogs with behavioral problems, lots & lots of dogs have behavioral problems & are a problems for groomers to do. Many even refuse to do a dog if it is too aggressive, so these dogs were brought to me.

Do you mean "Why" do people like dogs"?

If so, for many reasons, depending on the person.
Some people may like them for companionship and walking partner, and others may like them to help with some job. eg: herding sheep etc, security, guide dogs etc.
others may like them for competing in dog sports.
