Find your dream pet with Petfinder’s adoptable pet listings from over 11,000 shelters and rescues in the U.S., Canada, and Mexico. Shelters and rescues maintain their own pages on the site so you know they’re up-to-date and you’ll find the shelter’s email, address, and hours listed with every pet listing, making it easy to take the next step. The site is also packed with great resources on pet care and pet adoption, including the first month with a new pet.
