Story
Kingston is our distinguished and slightly older gentleman. He came to us as a stray, so his background is unknown. We learned that he loves to run and play in the yard. He is sweet but strong. He is getting better at leash walking. He was in a foster home briefly and decided he doesn't want to share his home with cats. His foster said he was guarded with the men he met. He has been reactive to the dogs here in the shelter, so he needs to be the one and only pet in the home. Kingston needs a home where he can curl up on the couch or a nice doggy bed and enjoy the day.

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
Hi… um… hello. 👋 My name is Levi. (This is the part where I pretend I’m not nervous.) I came in as a stray on 12/11/25 and the humans say I’m about 5 years old. Personally, I don’t keep track of time—just snacks and friends. I’m very friendly and playful, and I really want to be your buddy… I just might wiggle a little while introducing myself. Full disclosure: I’m a bit too thin right now, so I’m accepting applications for someone willing to help me put on some healthy weight. Preferably with treats. Lots of treats. 🍖 I am a total sweetheart and promise to repay you with love, smiles, and enthusiastic tail wags. Anyway… yeah… if you’re looking for a good boy who’s trying his best—hi, it’s me. I’m available for adoption, so please come meet me before I overthink this introduction any more. 😅 📍 Richland County Dog Shelter Mansfield, OH 📞 419-774-5892 📝 Adoption is an application process.

Meet Ridge!! 💙 This handsome guy came in as a stray on 12/11/25, and we think he’s about 6 years old.

He’s ready to trade shelter life for a warm couch, good meals, and lots of love. Ridge is available for adoption, so hurry in to meet him—you won’t regret it! 📍 Richland County Dog Shelter Mansfield, OH 📞 419-774-5892 📝 Adoption is an application process.

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.
