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

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
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.

Mr Woofers is a 4 to 5 yr old neutered male Mastiff mix. He weighs about 75 lbs. We pulled Woofers from our local animal shelter after he was picked up as a stray. He can be a little cautious when meeting new people but warms up quickly. You can convince him to do anything for a treat. He is lower energy and enjoys just hanging out with his family. He will go for a walk and does occasionally like a good romp in the yard. He has been kind and gentle . He appears to be house trained . He is great with other dogs and children. He hasn't been tested with cats. He is up to date on shots and wormed. He is already neutered. The adoption fee is $400.00. If interested in meeting this cutie, please email heritagefarms08@gmail.com or call the foster at 419-779-0862 . He is being fostered in Ottawa Lake , Michigan. When emailing please include information about you and your family including other pets.
