Benefits of having pets and why people own pets

My opinion is people just like having certain pets, for many varied reasons. We generally have a preference as to what pet we like for what ever reason. I like dogs best. They are loyal (usually), playful, affectionate and can do some pretty funny stuff. Dogs are company. Sometimes older people that live alone like having a dog or cat to keep from being alone. It gives them some place to put their love and affection. Keeps them from being as lonely. Families with kids, well, the kids like playing with the pet. I think most people like to be needed, a pet needs us. Back to dogs, they are really something. They are always glad to see you. You come home from a rough day, there is that tail wagger so very happy to see you. Your dog will not judge you if you have warts, are overweight, have three arms, the dog just does not care. Dogs are incredibly forgiving too. Unlike people who tend to be a tad two faced at times, you know where you stand with a dog. I remember something I read somewhere once, "Lock your wife and your dog in the trunk of your car. After two hours open the trunk. WHO is glad to see you?" Evidently that one is all over the internet.
