I believe dogs are one of the best pets to own. Why you may ask? Dogs are very loyal companions and love to play and be active. There are many different kinds of dogs, so there is many to choose from. Dogs love to play, but will also comfort you when your sick or need help. This is why I believe dogs are the best pet you can have.
