One of the easiest ways to search for adoptable dogs is to use a pet adoption website, such as Petfinder.com or AdoptaPet.com. These sites let local shelters and rescues list pets and allow you to search based on location, breed and other factors.
Petfinder.com lets you customize a search in detail, or you can simply look up shelters in your area and see what dogs they have listed. This is also a safe way to search for adoptable dogs, because Petfinder.com verifies that rescues are legitimate before allowing them to list pets on the website. Most shelters and rescues also maintain their own websites with lists of available dogs. You can usually find the contact information for municipal shelters on your city or county government's website.
You can also visit rescue organizations in person to see their dogs. Private rescues typically require a phone call or appointment. Some may not allow visits if they do not have a central kennel but rely on foster homes. Municipal shelters often allow you to visit unannounced during normal business hours.
Keep an open mind while searching for an adoptable dog, and consider what the shelter workers suggest. Shelter workers typically know their dogs' personalities fairly well and can help match you to your ideal companion, even if the dog isn't the first one that caught your eye.
