Nathaniel

Age: 5 months
Sex: Male
Breed: Chihuahua / Poodle Mix
Foster Location: Kenosha, WI

Nathaniel is ready to start the New Year exactly where he belongs — in a home of his very own. Now 5 months old, this scruffy, spirited Chihuahua/Poodle mix has grown into a confident, joyful puppy with a big personality and an even bigger heart. He’s expected to mature into a wonderful medium-sized dog, approximately 20–30 pounds, making him the perfect “not too big, not too small” companion.

Nathaniel has a bold, playful spark that makes him impossible to ignore. He approaches life with enthusiasm, prancing proudly with his toys and treating every squeaky like it’s the most important mission of the day. Playtime is one of his favorite things, and he brings a lighthearted, goofy energy wherever he goes.

When the fun winds down, Nathaniel happily shifts gears into cuddle mode. He loves curling up with his people and has a naturally affectionate, cozy side that makes him a wonderful companion for quiet moments just as much as active ones.

Nathaniel is very well socialized and does great with other dogs, cats, and children. He is kennel trained, doing well with potty training and leash training, and he thrives on praise and positive reinforcement. He’s a smart, eager-to-please puppy who enjoys learning and being part of a routine.

With his scruffy charm, joyful personality, and balanced energy, Nathaniel would do beautifully in a variety of homes — whether that’s an active family, a home with other pets, or someone looking for a playful but snuggly companion to grow with.

Stella Rose | 2 Years Old | Female | Blue Nose Bully Mix
Fostered in Pleasant Prairie, WI

Stella Rose is a compact, sweet-natured blue nose bully mix with a heart as warm as her soft, stocky little body. Though she may appear larger in photos, Stella weighs in at just 45 pounds and has that perfect “small but solid” build that makes her an ideal snuggle companion.

Stella is a well-mannered, calm, and loving dog who has already mastered many household basics. She is potty trained, kennel trained, and walks well on leash. Her temperament is gentle and easygoing, with a medium-to-low energy level that makes her a wonderful fit for families who enjoy a calmer, steady companion. She loves to relax, nap near her people, and spend quiet time hanging out around the home.

Even with her laid-back nature, Stella Rose still enjoys playtime. Her absolute favorite toy is her special green ball, and she loves tug of war and carrying around her stuffies. She plays well with other dogs, does great with children, and enjoys being part of the family routine.

Her foster mom describes her as sweet, loving, playful, and eager to please. Stella has also begun working with a professional trainer. Her future adopters will be given helpful guidance and information so they can continue reinforcing these skills and helping her succeed.

☀️ Roman ☀️
6 Months Old | Male | Catahoula x Pittie Mix
📍 Fostered in Beach Park, IL

Roman is the kind of dog who carries sunshine wherever he goes. With one warm honey-brown eye and one striking icy-blue eye, he has a presence that instantly captures attention. People stop mid-step to admire him—and Roman, with his joyful grin and playful confidence, is always happy to say hello.

When Roman first arrived at Mastro Mutts, life hadn’t been very kind to him. He was struggling with flea dermatitis, his skin irritated and uncomfortable, and it was clear he didn’t feel his best. With proper medical care, good nutrition, and the safety of a loving foster home, everything changed. His skin healed beautifully, his coat grew in healthy and shiny, and his bright, spirited personality finally had room to shine.

Today, Roman is a thriving, intelligent, and affectionate young dog who is ready for a home of his own. He is fully potty trained, kennel trained, and does wonderfully on leash. Roman is extremely social—he gets along great with other dogs, is gentle and respectful with cats, and absolutely adores kids. He truly believes the world is full of friends and approaches life with an open heart.

Roman has a high energy level and thrives when he has opportunities to stay active and engaged. He loves toys of all kinds and brings enthusiasm and curiosity to everything he does. Despite his lively spirit, Roman is deeply devoted to his people. He forms strong bonds, loves wholeheartedly, and has a way of making his humans feel like the most important part of his world.

Roman would do best with an adopter or family who has the time, energy, and desire to include him in daily life—someone who enjoys walks, playtime, training, and shared adventures. With continued guidance, consistency, and love, Roman has all the potential to grow into an exceptional lifelong companion.

If you’re looking for a dog who is resilient, joyful, affectionate, and ready to be someone’s sunshine, Roman may be the perfect addition to your home.

Charger — A Heart of Gold for Her Golden Years

Foster Location: Kenosha, WI
Age: 10 Years Old • Female • Labrador Retriever Mix

Charger is a remarkable senior girl with a gentle spirit, a bright soul, and a whole lot of life left to enjoy. At 10 years old, she embodies the perfect blend of youthful energy and mature calm. She still plays with the enthusiasm of a younger dog, yet she also knows how to settle in, relax, and soak up the love around her.

She originally came to us after her previous owner experienced medical challenges that made it impossible to continue caring for her. Charger was dearly loved, and it shows in her sweet nature, her trust in people, and her quiet confidence. We are honored to help her find a new forever home — one where she can continue to thrive.

Charger is fully potty trained, having only a couple of minor accidents when she first arrived while adjusting to her new routine. She is wonderful with other dogs, respectful of cats, and excellent with children. She is kennel trained, though she rarely needs to be kenneled because she is such a well-behaved girl. On leash, she walks beautifully and stays right by your side, making outings enjoyable and easy.

She has excellent recall and knows all her basic commands, including “in” when asked to go into her kennel. Charger loves toys — especially tennis balls — and enjoys a mix of playtime and relaxation. She also appreciates the little luxuries in life, such as a cozy dog bed, warm blankets, and the occasional shared bite of dinner with her human.

Charger sleeps soundly through the night, whether she’s curled up in her foster parent’s bed or resting comfortably in her orthopedic dog bed. She adjusts well to routines and brings a sense of peace and joy into the home.

Because she came to us so well cared for, we have set her adoption fee low. Her foster mom is committed to being selective simply because Charger is extraordinary and deserves a forever home filled with love, stability, and kindness.

If you’re searching for a devoted companion who will brighten your days and bring warmth to your home, Charger may be the perfect match. She has so much love left to give and is ready to begin her next chapter.

Male | Mixed Breed Puppy | Available on or after January 21st

Every litter has a leader — and Memphis wears that title proudly. Confident, outgoing, and full of personality, Memphis is the puppy who charges into life headfirst, tail wagging and ready for whatever comes next. He’s bold in the best way and completely unfazed by the world around him.

Memphis is the leader of the pack and thrives right in the middle of the action. He isn’t fearful of anything and approaches new experiences with curiosity and confidence. Toys are his absolute favorite, and if there’s a game happening or friends nearby, Memphis is already there, making sure the fun keeps going.

Playful and social, Memphis has been well socialized and does wonderfully with other dogs, kids, and cats. He’s currently being fostered in Kenosha, WI, where he’s learning what it means to be part of a loving home while growing into his big personality.

Mia

📍 Fostered in Salem, WI
Female | Mixed Breed Puppy | 8 Weeks Old

If joy came in puppy form, it would look a lot like Mia. Sweet, silly, and endlessly lovable, Mia is a little ball of happiness who approaches life with a wagging tail and a heart full of optimism. We believe she is a pittie mix, possibly with some border collie, giving her a wonderful blend of playful energy and affectionate charm.

Mia has a perfectly balanced personality — she loves to play hard and nap just as hard. Her favorite activities include romping around with other dogs, tossing her beloved crinkle toys, and then curling up for a well-earned snooze. She brings a light, joyful energy wherever she goes and has a way of making people smile without even trying.

In her foster home, Mia is doing great with kennel training and is actively working on potty training and leash training. She has been well socialized and does wonderfully with other dogs, cats, and kids, making her a fantastic fit for many different types of homes.

Mia is confident, curious, and loving — though she does have one known weakness: the vacuum cleaner. It is clearly suspicious, possibly evil, and best avoided at all costs. Thankfully, everything else in the world is pretty wonderful in her eyes.

Mia is currently being fostered in Salem, WI, and she’s ready to bring laughter, love, and puppy snuggles into her forever home. She’s the kind of pup who will grow into a loyal companion and fill her family’s days with happiness.

Patch

📍 Fostered in Silver Lake, WI
Male | Red Heeler Mix | 10 Weeks Old

Meet Patch — a smart, sweet, and incredibly lovable red heeler puppy who may or may not be a mix… and honestly, there’s a good chance he’s the real deal. Since we don’t have his full background, we’re calling him a red heeler mix, but one thing is certain: Patch is a truly exceptional little guy.

Patch is currently being fostered in Silver Lake, WI, where he’s thriving in a home environment. He has been well socialized and does excellent with other dogs, cats, and kids. He is comfortable in a kennel when necessary and is already working hard on important puppy skills such as potty training, leash training, and basic commands.

For a heeler puppy, Patch currently has a moderate energy level, but it’s important to note that heelers are known for their endurance, intelligence, and drive as they mature. As Patch grows, he will do best in a home that can provide regular walks, mental stimulation, and opportunities for adventure — or maybe even a few sheep to herd someday.

Patch loves all toys equally — bones, ropes, stuffies — if it’s a toy, he’s interested. He’s playful, curious, and eager to engage with both people and his environment.

What truly makes Patch special is his connection to people. He loves being close, follows his foster around the house, listens remarkably well for his age, and often settles at their feet while they cook. He’s affectionate, attentive, and incredibly smart — the kind of puppy who forms strong bonds quickly.

Patch is going to make a wonderful companion for a family ready to welcome a loyal, intelligent, and active pup into their lives.

She’s the perfect blend of playful energy and cozy companionship, making her an ideal match for someone who loves to get out and do things but also appreciates quiet moments at home.

Windixie has a higher energy level that makes her a fantastic partner for walks, outings, and playtime. She’s always ready to go when something fun is happening and brings a joyful enthusiasm to everything she does.

📖 Noah 📖

Noah is a puppy straight out of a love story — the kind that unfolds slowly, sweetly, and stays with you long after the final chapter. Calm, affectionate, and deeply people-oriented, this 10-week-old boy has a heart built for connection and a soul that feels instantly familiar.

While his exact breed mix is unknown, we do suspect a bit of Jack Russell charm in his DNA, thanks to his expressive eyes and curious nature. That said, Noah’s personality leans more toward the romantic than the rambunctious. He is gentle, loving, and happiest when he’s close to his people — especially if belly rubs are involved. In fact, belly rubs may be his primary love language.

Noah gets along beautifully with kids, cats, and other dogs, making him a wonderful fit for a wide variety of households. Though he’s friendly with everyone, he clearly prefers humans above all else and forms strong bonds with those around him. He’s the kind of puppy who follows you from room to room, content just being nearby.

Sweet, snuggly, and emotionally available, Noah is ready to grow up alongside a family who will cherish him for a lifetime. If you’re looking for a puppy who offers quiet devotion, constant companionship, and unconditional love, Noah may be the one you’ve been waiting for.

💙 Boots 💙
11 Weeks Old | Male | Mixed Breed
📍 Fostered in Kenosha, WI

Boots is an 11-week-old puppy with a larger-than-life personality packed into a small, adorable body. He brings nonstop joy and entertainment to his foster home and has a way of keeping everyone smiling from morning to night.

While officially listed as a mixed breed, Boots shows strong Red Heeler traits in both appearance and personality. He is curious, intelligent, and always eager to be part of the action. Like many puppies his age, he can be a bit of a picky eater, but he’s learning good habits and doing well with his puppy food.

Boots is making steady progress with potty training and will typically use a potty pad if he can’t get outside in time. He does well in his kennel when needed, though he especially enjoys sleeping close to his people at night. He is calm and well-behaved through the night and happily settles back down after brief wake-ups.

He does wonderfully with other dogs, kids, and cats. True to his heeler instincts, Boots can occasionally try to herd his people and animal friends, but he is learning appropriate behavior and responds well to guidance and continued training.

Boots enjoys playing in the backyard with other dogs, staying warm and cozy, and being near his people. He is also working on leash training and is doing very well for his age. Smart, affectionate, and full of personality, Boots is a puppy who will thrive in an active, engaged home.

💖 Priya 💖
11 Weeks Old | Female | Large-Breed Mix
📍 Fostered in Kenosha, WI

Priya is an 11-week-old puppy who is already turning heads with her size, presence, and gentle nature. Weighing in at over 20 pounds at such a young age, Priya is expected to grow into a large adult dog. Based on growth estimates, she may reach anywhere from 106–130 pounds when fully grown, though as with all puppies, this is only an estimate and genetics can always surprise us.

We suspect there may be mastiff in Priya’s lineage, not only because of her size, but because of her calm, thoughtful demeanor. Priya approaches the world with curiosity and confidence, taking time to observe and learn rather than rushing headfirst into everything. She enjoys exploring at her own pace and shows a natural eagerness to learn.

In her foster home, Priya has been very well socialized and does wonderfully with other dogs, kids, and cats. She has a sweet, affectionate personality and a steady, gentle presence that makes her especially appealing to large-dog lovers. Priya is already showing the traits of a future gentle giant—loving, calm, and deeply connected to her people.

Priya will thrive in a home that appreciates large breeds and understands the needs of a growing big dog, including continued training, structure, and plenty of love.

💙 Paxton 💙
11 Weeks Old | Male | Large-Breed Mix
📍 Fostered in Kenosha, WI

Paxton is an 11-week-old puppy with an impressive size, calm demeanor, and an incredibly gentle heart. Even at a young age, he’s already showing signs of growing into a very large adult dog, and we expect him to exceed 100 pounds once fully grown.

While we don’t know Paxton’s exact breed mix, we suspect there may be mastiff and/or Rottweiler in his lineage based on his size and build. Among his littermates, Paxton is the largest — and also the most relaxed. He has a naturally laid-back personality and prefers cuddling and lounging over high-energy play, making him a wonderful match for someone who appreciates a calm, affectionate companion.

Paxton has been well socialized in his foster home and does beautifully with other dogs, kids, and cats. He is especially gentle with the youngest member of his foster family, a baby just 6 months old, demonstrating his patient and nurturing nature. Despite his size, Paxton is careful, sweet, and attentive with everyone he meets.

Affectionate, easygoing, and full of love, Paxton is already showing all the signs of becoming a true gentle giant. He will thrive in a home that understands the needs of a large-breed dog and is ready to continue his training and socialization as he grows.

💙 Parker 💙
11 Weeks Old | Male | Large-Breed Mix
📍 Fostered in Kenosha, WI

Parker may be the smallest member of his giant litter, but don’t let that fool you—this boy is still impressively big. At just 11 weeks old, Parker already weighs 17 pounds, putting him on track to reach an estimated 80–90 pounds as an adult. “Small” is definitely a relative term here.

We believe Parker likely has Mastiff in his mix, based not only on his size but also his steady, thoughtful demeanor. He has a calm confidence about him, taking time to observe before jumping into the action, and he carries himself like a puppy who already knows he’s going to be a big dog someday.

In his foster home, Parker has been well socialized and does great with other dogs, kids, and cats. He’s gentle, friendly, and easygoing—an excellent combination for a large-breed puppy. While he’s curious and playful, he isn’t over-the-top, making him a wonderful fit for a family looking for a big dog with a balanced temperament.

Parker is the kind of puppy who will grow into a loyal, loving companion—large in size, but equally large in heart.

💙 Preston 💙
11 Weeks Old | Male | Large-Breed Mix
📍 Fostered in Kenosha, WI

Preston is an 11-week-old puppy already known as the gentle giant of his litter. While he’s still very much a baby, it’s clear he’s going to grow into a large adult dog with an even larger heart. Preston combines size, sweetness, and a calm confidence that makes him truly special.

Among his littermates, Preston stands out as the adventurous, curious, and brave one. He enjoys exploring his surroundings and approaching new experiences with confidence, but he balances that curiosity with a wonderfully gentle and affectionate nature. Preston loves to cuddle and is happiest when he’s close to his people, soaking up attention and reassurance.

Preston has been very well socialized in his foster home and does exceptionally well with other dogs, cats, and children. He has also shown himself to be remarkably gentle with babies, displaying patience and awareness far beyond his age. His temperament suggests he will grow into an excellent family dog—steady, loving, and deeply bonded to his people.

Currently fostered in Kenosha, Preston is receiving lots of love, socialization, and positive experiences as he prepares for his forever home. He is the type of puppy who will mature into a loyal companion, a comforting presence, and a big dog with a soft soul.
