Domestic Dogs Wanted
Dogs make great companions. They provide their owners with an opportunity to love and nurture another living thing. In return they are loyal, offer protection to their owners, and are fun to have around. Dogs come in all different shapes, sizes, and colors. However, all these different breeds have the same basic dog characteristics. Unfortunately, sometimes dogs are abandoned or run away from home. Many of these unwanted and stray dogs end up in animal shelters where they can be adopted by new owners.
