There are countless people out there who would be interested in adopting a dog, but are held back by the fear that there could be something wrong with it. There are concerns that it may be too afraid of humans and never learn how to properly interact with people. While those problems certainly do exist, they seem to be few and far between. Most people who adopt a dog, or any other animal for that matter, never encounter any of those problems. If you love your pet, they'll love you back. It's often as simple as that.
But don't take my word for it. See for yourself.
