Story
Meet Lazarus, the stunning Mastiff mix with a heart as big as his paws — and the spirit to match! Lazarus may only have three legs, but don’t let that fool you for a second. It doesn’t slow him down at all. This friendly giant loves to play, explore, and soak up attention from anyone willing to give it. Lazarus is good with all people and gets along with other dogs. He came to us from Louisiana, and while we don’t know what his past held, we do know his future looks bright now that he’s safe, loved, and ready for his forever home. He is microchipped, neutered, and up to date on vaccines. If you’re looking for a joyful, resilient, and affectionate companion, Lazarus is your guy!December 8, 2025, 12:10 pm

Story
Eggnog is a beautiful young Boerboel girl with a big heart and an even bigger potential. She’s still learning about the world and what it means to feel truly secure, so she’s seeking a family who understands the needs and quirks of large, powerful breeds.She’s a bright, observant dog who likes to take her time getting comfortable, but once she does, her affectionate and loyal nature really shines. Because of her size and strength, Eggnog will thrive with adopters who are confident, patient, and experienced with large breeds. Eggnog may enjoy living with another well-matched dog her size — someone steady and social who can help her feel at ease. Due to her strength and her still-growing confidence, she’d do best in a home with teens and up, or adults only.If you’re looking for a devoted companion who’s ready to bond deeply with the right people, Eggnog could be your perfect match. Come meet this sweet girl and see why she’s as warm and comforting as the holiday treat she’s named after.

Story
You can fill out an adoption application online on our official website. Fill out an Adoption Application Zoey (fka Ruckus) came back to MTM after being adopted several years ago and her adopter recently passed away.    She is doing great in her foster home living with a toddler, 2 young kids and dogs of all sizes.   Zoey did take a bit to adjust. She is shy at first meeting, but once she settles in, she seeks attention and thrives off of routine. So if interested in meeting her, please understand, she does not show well, but given some time and patience, she will come around and show great affection.    She has begun to engage the other dogs in play and loves to spend time outside in the yard. She does well being left alone with the other dogs, with no concern of messes or destructive behavior.     She does pull on the leash and will need some help with that, but that too needs to be made part of her routine. Zoey is a low to medium energy dog and is content to just hang out. She will pick a favorite bed and that becomes her spot.    Zoey does well riding in the car, was well behaved at the vets office and doesn't mind a nail trim as long as shes being scratched at the same time.   She is potty trained and will go to the door or even come wake you if she needs to go out.    Zoey has been fully updated on vaccines and received a dental. She is ready for a new family! Visit this organization's web site to see any additional information available about this pet.
