Story
🃏 MEET JOKER!! 🃏 Origin Story: Stray turned Sidekick Supreme Joker rolled into the shelter as a stray on 1/15/26 with his ride-or-die bestie, Harley Quinn. We estimate this charming rogue is about 5 years old, and while he may give you a cautious side-eye at first… don’t blink — that phase ends fast. Once he decides you’re not part of the evil plot, Joker reveals his true powers: friendliness, curiosity, and expert-level pet acceptance. He enjoys attention but isn’t a full-time cuddle villain — he prefers to stay mobile, exploring his surroundings like the independent antihero he is. Fuel of choice? 🌭 Hot dogs. Weakness? 💔 Being away from Harley Quinn. When his partner-in-crime is nearby, Joker is all smiles and good vibes, proving that even a trickster needs his trusted sidekick. Joker is ready to leave the shelter and star in his own happily-ever-after issue. Don’t miss your chance to meet this lovable character — hurry in before this comic book legend is adopted! 📍 Joker is located at the Richland County Dog Shelter in Mansfield, OH 📞 Phone: 419-774-5892 📝 It is an application process. You can request one via dogs@richlandcountyoh.gov

Story
💥🎀 MEET HARLEY QUINN!! 🎀💥 Origin Story: Stray turned Chaos Queen Harley Quinn bounced into the shelter as a stray on 1/15/26, arriving hand-in-paw with her favorite partner-in-crime, Joker. We think this stunning gal is about 5 years old, and while she may size you up at first… don’t worry — that hesitation disappears faster than a “POW!” bubble. Once she warms up, Harley shows off her true superpowers: friendly charm, adventurous spirit, and elite-level snack appreciation. She loves being petted but isn’t the clingy type — this girl prefers to keep moving, exploring her surroundings like the confident comic book heroine she is. Signature snack? 🌭 Hot dogs. Sidekick status? 🃏 Joker is her number one. When they’re together, Harley is all smiles, proving that every great character shines brightest with their favorite teammate nearby. Harley Quinn is ready to leap off the pages and into her forever home. Don’t miss your chance to meet this bold, beautiful girl — hurry in before her next adventure begins! 📍 Harley Quinn is located at the Richland County Dog Shelter in Mansfield, OH 📞 Phone: 419-774-5892 📝 It is an application process.

Story
🐾 Meet Brady! 🐾 Brady is a handsome 3.5-year-old Mastiff mix who is learning that the world can be a pretty wonderful place—and that people can be trusted. Give this big guy a little time to feel safe, and his sweet, playful personality starts to shine! ❤️ 🐶 Dog Friendly: Brady does well with other dogs and tends to follow their lead. He’s still figuring out his own opinions, but his foster friends are helping show him the ropes! 🐕 👨 A Little Shy: Brady can be timid at first, especially around men. Calm, patient introductions are his love language. 💙 💨 Fast Movements: Quick or unexpected movements can make him nervous, so he does best with people who understand that confidence takes time. ❤️ Once He Chooses You: Watch out—once Brady decides you’re his person, you’ve got a loyal friend for life! 🥰 👧 Kid Friendly: Brady enjoys children and does well with them when they aren’t overly rambunctious. 🐱 Cats: No cats, please. 🏠 House Training: A work in progress, but Brady is learning! 🛏️ Crate Comfort: He is clean and comfortable in his crate and has figured out that it’s a nice place to relax. 🦮 Leash Skills: Brady walks well on a leash and is ready to enjoy some adventures with his forever family! 🎓 Smart Guy: He knows sit and down and is working on stay. 🦴 Treat Expert… Sort Of: Brady takes treats VERY nicely… now if only someone could teach him how to actually catch one! 😂🍪 🎉 Fun Side Loading…: His funny, playful personality is coming out more and more as his confidence grows. 💞 The Brady Experience: Give him a little time to learn that you’re safe, approach him calmly and patiently, and watch that shy little shell start to crack. Before you know it, Brady will be loving you with his whole big heart. ❤️🐾 ✨ Brady isn’t looking for someone to rush him—he’s looking for someone willing to let him bloom. And we have a feeling the wait will be worth it! ✨ Age: 3.5 years Adoption Fee: $350 MBR holds monthly adoption events on the 2nd Saturday of every month at Tractor Supply in Columbia Station, 24100 Royalton Road from 11 am - 2 pm. Questions can be emailed to rescue@mbrohio.com If you are interested in adopting one of our dogs, the first thing to do is submit an application for approval.
