Story

Dozer is a neutered male, black/white Mastiff Hi! I'm Dozer! I am deaf! I really don't know how to play. It’s kind of sad. I have a little routine here - I just go in my pen, eat a few bites, drink then run back out for a treat. I like being near my people & will follow you around. I am not interested in playing ball. I really just don't know what to do with myself other than just enjoy life. I am so sweet, according to my foster. So if you don't mind a good-sized velcro dog, I'm your guy! ##2498995##

Story

My parents got tucker from my neighbors when he was a puppy and they were not good dog owners so i ended up taking him in but i cannot have him where im currently living and dont have anyone who can help out. hes starting to have hip issues but other than that hes perfectly healthy he doesn’t like being trapped in one room and likes to roam around and follow you around the house, which he currently isn’t able to do. he also does good outside to a degree but primarily has been an inside dog most of his life

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. If you recognize this animal please contact the adoption center at 509-457-6854.Did you know YHS offers a `Play Date` program?Whether you are interested in adopting or just want to hang out with a furry friend, it`s a fun way to spend an hour, an afternoon or even a couple days.
