Story
You can fill out an adoption application online on our official website. Fill out an Adoption Application HEADLINER: Your new, lovable sidekick awaits! HISTORY: Unknown. Found abandoned in Kentucky with his mom                                                   PERSONALITY: Norman is such a sweet, mild-mannered boy. He is still shy when meeting new people and can be fearful of men/reactive to loud noises, but once he knows you, he is a total love bug! Norman thinks that all dogs and cats are just friends he hasn’t met yet, but he also respects when this opinion isn’t reciprocated. Since Norman is still young, he enjoys some bouts of playfulness, but he also enjoys his naps and sleeping in. FAVORITE ACTIVITIES: Carrying around his toys, making new friends, being close to his person/people, and being loved on. MEDICAL ISSUES: No known issues.  WHAT WOULD BE THE BEST KIND OF HOME:  Norman would love to have a home where he gets plenty of love and attention, and hopefully has some four-legged friends to play with. Although he is doing fairly well with house-training, he will need someone that understands his cues. He will also need someone that understands that he is still a puppy and doesn’t know the difference between an acceptable toy and your slippers. Norman is also quite the ladies man and seems to prefer females over males for his human(s). Visit this organization's web site to see any additional information available about this pet.

Story
You can fill out an adoption application online on our official website. Fill out an Adoption Application Melvin is a young Boerboel mix, estimated to be about 1 year old, who came to us as a stray. We don't know much about his past, but we are excited to help him findthe bright future he deserves. Melvin is a big, goofy boy with an even bigger heart. He absolutely loves other dogs, especially dogs his own size, and nothing makes him happier than a good game of chase or some rough-and-tumble wrestling with a canine friend. Because he's still young, he's full of energy and doesn't always realize just how big he is. One of Melvin's sweetest qualities is how quickly he bonds with his people. He's a true shadow dog who wants to be wherever you are. Whether you're making dinner, watching TV, or working around the house, you will find a big slobbery face following right behind you. He loves being part of the family and is happiest when he's included. Melvin already has a great foundation for his new family. He's house-trained, crate-trained, and walks nicely on a leash, making the transition into his forever home that much easier. He still has plenty to learn, and needs someone who will teach him. He's been around children and has done well, though his size and enthusiastic play style mean he'll do best with a family that can help him continue learning good manners. Melvin is eager to please and will thrive with patient guidance, regular exercise, and lots of opportunities to play. Melvin should not be placed in a home with cats. He simply wants to play with them the same way he plays with big dogs, and because of his size and rough play style, it's just not safe for feline friends. If you're looking for a loyal companion who will stick by your side, make you laugh with his oversized puppy antics, and happily cover you in a little slobber along the way, Melvin may be the perfect fit. He didn't get to choose how his story started, but he's more than ready for a family to help write the rest of it. Click here to watch a video of Melvin.Visit this organization's web site to see any additional information available about this pet.

She is already spayed and has had gastropexy surgery done. Athena would benefit from training and would do best with someone who is strong enough for her as she is a leash puller. Athena is a big girl who needs assistance getting into vehicles. Athena needs a home with no cats, farm or small animals of any kind as she has a high prey drive.Click here to watch a video of Athena *Courtesy Post*.Visit this organization's web site to see any additional information available about this pet.

Story
Meet Nebula! Nebula is a smart girl who's eager to learn and wants so badly to get it right. She's full of potential and has already shown that she picks up on training quickly with structure and consistency. After she's had an outlet for her energy, she's all about soaking up affection from her people. Like many young, energetic dogs, Nebula is still learning how to channel her excitement. When she gets overwhelmed, she can forget her manners, so she'll do best with a family that's committed to continuing her training and giving her the structure she thrives on. Nebula would make an amazing adventure buddy for someone who enjoys hiking, exploring, or staying active. Apply for this fun girl today!

Story
Meet Sneezy, one of the Seven Dwarfs! No tissues required—this brindle beauty will only make you fall in love! Born on May 20, 2026, Sneezy is a Mastiff/Pit Bull mix who came to us from a hoarding situation and is ready to start her happily-ever-after. Like any puppy, she's playful, affectionate, endlessly curious, and always looking for her next adventure (or something she probably shouldn't be chewing on). She plays hard, naps even harder, and is expected to grow into a medium-to-large dog, likely around 50-60 pounds. Sneezy will thrive with a family committed to training, socialization, and providing plenty of exercise and mental enrichment as she grows. As a young puppy, she should adapt well to homes with other dogs, cats, and children. If you're ready for puppy kisses and lots of laughs, Sneezy is waiting! Apply at lvpeaceablekingdom.info.

Story
Meet Miracle! They say everyone could use a little miracle in their life, and we happen to know one with four paws and a wagging tail. This 4-year-old, 65-pound Mastiff/Boxer mix came from a hoarding situation and raised a litter of puppies just six months ago. Now it's finally Miracle's turn to be cared for. She is incredibly sweet, calm, and affectionate with people, with a gentle nature that makes everyone she meets fall in love. Miracle is eager to please, seems to genuinely want to follow directions, and should be very receptive to training. She also walks nicely on a leash, especially for a dog her size. Miracle gets along well with other dogs, although she may need to be separated for feedings as she may guard her food. She would likely do great with children and can be cat tested if needed. If you've been waiting for a sign that your perfect companion is out there, maybe this is your Miracle. Apply at lvpeaceablekingdom.info.
