Mars is the shelter’s longest resident, and he’s more than ready to figure out home life with the right person. He’s smart and picks up new things fast—couch lounging, snuggling, and loving attention have already become favorites. Mars gets along well with kids and prefers female dogs. He’s not suited to homes with male dogs or cats. With patience and a gentle approach, Mars will settle in and thrive. He already knows some basic commands and is house trained, so the groundwork is there—he just needs someone who wants to help him move forward. At around 4 to 5 years old and heartworm negative, Mars is searching for that family who will finally bring him home. Ready to meet your new best friend? Apply now!
