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

💥🎀 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 Clarice 🐾100 lbs of love, personality, and lap-dog energy—Clarice is ready to be your one and only!.  This 7-year-old, 100 lb gal is a lovable supermutt, likely a Lab/mastiff-type mix with a strong, stocky build (and maybe a little bulldog mixed in). Clarice is the definition of a people dog. She absolutely lights up around humans, loves kids, and greets new friends with full-body wiggles and happy enthusiasm. She’s a cuddler at heart and truly believes she belongs in your lap—despite her size!She’s also smart and well-trained, having gone through our prison obedience program, so she comes with a great foundation and knows her commands. Clarice enjoys car rides, loves her rubber and tough chew toys, and brings a fun, playful energy to everyday life.We’re also learning something new about Clarice! While we previously believed she would need to be the only dog in her home, she recently surprised us by happily making friends and playing with an easygoing dog close to her own size. This opens up the possibility that Clarice may be able to share her home with the right canine companion. A meet-and-greet with any resident dog would be required to make sure everyone is comfortable and it’s a good match. She would also be perfectly happy as your one and only, soaking up all the attention for herself.She is used to living in a home and lost it through no fault of her own. Clarice is ready to settle back into family life and is hoping for a forever home that will truly be forever.If you’re looking for a loyal, affectionate companion who will keep you laughing, keep you company, and happily claim your entire couch… Clarice just might be your girl. ❤️.
