Rex is a one-year-old Border Collie/Terrier mix with a keen gaze and a big, goofy personality. His littermates have all moved on, but Rex is still waiting to find the right family. In his foster home, he's finally starting to come out of his shell—and the progress shows. Rex loves to chase golf balls, toss his toys, and gnaw on bones. He lives for sprinting around the yard and chasing squirrels, and he has a definite thing for chasing cars, so a fenced-in yard is non-negotiable for his safety. He has a lot of energy and will thrive in an active household, especially with someone who enjoys walks and outdoor play. Rex is making steady gains with socialization and regularly tags along for outings to stores, wineries, and dog parks. He's come a long way since his timid early days. Rex does get along well with other dogs and would benefit from a playful canine buddy. However, a home with cats isn't the best fit. He's initially shy with new people but warms up when he senses trust. Once you've earned it, expect a loyal and lively sidekick. He’s neutered, microchipped, fully vaccinated, and on monthly preventatives. Rex has left his nervous puppy days behind and is embracing life with enthusiasm—he just needs a family willing to help him keep growing. Ready to meet your new best friend? Apply now!
