Story

Meet Chance!Chance came to our adoption center with a limp, but he’s recovering well and feeling better every day. He’s a mature, sweet boy with an easygoing personality—truly a “go with the flow” kind of dog. Chance walks nicely on leash, loves treats, and is happy just hanging out with his people.He’s done great spending time in the manager’s office, showing us that he’s calm, well-mannered, and comfortable relaxing in a quiet space. Chance is what we’d call a pretty casual dude.One thing that really tugs at our hearts—Chance doesn’t seem to know about the finer things in life yet, like cozy dog beds or soft blankets. It’s clear he hasn’t had many comforts before, and we would love nothing more than to see him go to a home that can show him just how amazing life can be.Chance is ready for a loving home, a comfy bed, and someone who will give him the care and kindness he’s been missing. Could that be you?This pet is available for adoption on 12/19/25 at the Yakima Humane Society adoption center.
