Isaac
Isaac
Age: 11 Weeks
Sex: Male
Location: Kenosha, WI (Foster Home)Don't let Isaac's size fool you—this little guy is convinced he's the biggest dog around.
Full of confidence and personality, Isaac approaches every day like he's in charge. Whether he's proudly carrying around a toy, leading the charge into the backyard, or making sure everyone knows he's part of the action, Isaac has a larger-than-life attitude that's impossible not to love.
His journey to Mastro Mutts wasn't an easy one. Isaac was abandoned in a laundry basket, battled a serious infection, and heartbreakingly lost most of his siblings while they were in a shelter. Thankfully, those difficult days are behind him. Today, Isaac is healthy, thriving, and ready to start the next chapter of his life with a family of his own.
While we don't know his exact breed mix, we believe Isaac will grow into a wonderful medium-sized dog.
Isaac is a bright puppy who loves learning. He is kennel trained, doing an excellent job with potty training, and continues to make great progress with leash walking. He has been well socialized and gets along wonderfully with other dogs, children, and cats.
He has a medium to high energy level and enjoys staying active, but what makes Isaac truly special is the contrast in his personality. He loves acting like the "top dog," but once he's finished playing, all he wants is to be babied. He's happiest curled up next to his people, soaking up affection and reminding everyone that beneath his confident exterior is a sweet, cuddly puppy.
Because Isaac enjoys being the boss, he would do best in a home with canine siblings who are larger than he is. Bigger dogs help balance his playful confidence while giving him companions he can continue to learn from.
If you're looking for a puppy with a big personality, an even bigger heart, and enough charm to keep you smiling every day, Isaac could be the perfect addition to your family.

Ranger
Meet Ranger
Age: 11 Weeks
Sex: Male
Location: Fostered in Kenosha, WI
Breed: Australian Cattle Dog (Heeler)If you're searching for an active, intelligent companion who is always ready for the next adventure, Ranger may be the perfect match!
Ranger is an 11-week-old Australian Cattle Dog (Heeler) puppy with a playful personality and a heart full of love. Like many Heelers, he's incredibly smart, curious, and thrives when he has both physical exercise and mental stimulation. Whether he's playing fetch, exploring the outdoors, or learning something new, Ranger is happiest when he's on the move.
He has been well socialized and does wonderfully with other dogs. Ranger has also done well around cats, although he enjoys encouraging them to play and may occasionally give chase. Because of this, he would do best with confident, dog-savvy cats who won't be intimidated by his playful nature.
As a typical Heeler puppy, Ranger is still learning appropriate puppy manners. He can be mouthy during play and doesn't always realize how enthusiastic and strong he is, so we recommend a home with older children who can comfortably participate in his continued training.
Ranger will thrive with an active family that is committed to providing daily exercise, ongoing training, and plenty of enrichment. Walks, hiking adventures, games of fetch, puzzle toys, and obedience training will help him grow into the confident, well-mannered companion he's destined to become.
With consistency, patience, and love, Ranger will reward his family with unwavering loyalty, endless affection, and a lifetime of adventures.
Adoption Fee: $450

This energetic girl loves being outside, going for walks, running around, and playing with balls, sticks, and any toy that makes noise. Pink tennis balls are her absolute favorite! Reece enjoys being where the action is and loves spending time with other dogs.

Age: 14 Weeks
Sex: Male
Breed: Scruffy Mixed Breed (Best Guess)
Location: Fostered in Kenosha, WIAllen is the kind of puppy who doesn't need to be the center of attention to steal your heart. With his easy-going personality, adorable scruffy face, and gentle nature, he's happiest simply being part of whatever his family is doing.
When Allen first arrived at Mastro Mutts, he had already overcome more than most puppies ever should. He came to us with demodectic mange, a non-contagious skin condition caused by naturally occurring mites that can temporarily overpopulate in puppies with developing immune systems. While it can look concerning, it is completely treatable, and we're thrilled to say that Allen has made a full recovery. His coat is growing back beautifully, and he's now healthy, happy, and ready to begin the next chapter of his life.
Although we don't know Allen's exact breed mix, there's no denying his charming scruffy coat and expressive face. He's a handsome little guy with a calm, lovable personality that makes him a joy to have around.
Allen has been well socialized and gets along wonderfully with other dogs, cats, and children. He enjoys being included in everyday family life and is content whether everyone is out playing in the yard or relaxing together at home.
For just 14 weeks old, Allen is already impressing everyone with his progress. He is kennel trained, nearly potty trained, and continues to build confidence with leash walking. He's a smart puppy who enjoys learning and is well on his way to becoming a wonderful lifelong companion.
Allen has a moderate energy level and enjoys a healthy balance of playtime and relaxation. His favorite "toys" are often the simplest ones—sticks collected from the yard and unstuffed toys are among his top choices. He loves to play but is equally happy lounging nearby, watching the activity around him, and simply being part of the family.
His foster family describes him as easy-going, affectionate, and happiest when he's spending time with his people.
Allen has already proven how resilient he is. Now all he needs is a forever family to give him the love, stability, and happy life he deserves.

Poe's favorite toys include sticks, tennis balls, and anything that squeaks. If there's a stick to proudly carry around the yard or a ball to chase, you'll find him right in the middle of the action. He also has an unexpected hobby—gardening. Whether he's "helping" inspect flower beds or carefully investigating freshly turned dirt, Poe believes every yard could use his expert supervision.
His foster family describes him as stoic and whole-hearted, with a quiet confidence that's impossible not to admire. But don't let that serious face fool you—when the mood strikes, Poe can be sneaky as sin, finding creative ways to entertain himself or quietly investigate whatever has captured his curiosity. His personality is the perfect blend of thoughtful, affectionate, playful, and just the right amount of mischief.
Poe is proof that resilience comes in small packages. After everything he's overcome, he's ready to leave his past behind and start the next chapter of his story with a family who will love him for the incredible puppy he is.
If you're looking for a loyal companion with a gentle heart, a playful spirit, and just the right amount of puppy charm, Poe may be your perfect match.

Sadie Mae
Sadie Mae
1 Year Old • Female • Mixed Breed
Sadie Mae is an adorable young dog with short little legs, a long body, and a personality that continues to shine more every day. While we cannot confirm her exact breed mix, her appearance makes us fairly certain that there is some Corgi in her family tree.
She is well socialized and does great with other dogs, children, and cats. Sadie Mae also walks nicely on a harness and has been eager to learn everything her foster home has introduced to her.
We do not know what Sadie Mae’s life looked like before coming into rescue. When she first arrived, she was not potty trained and seemed a little unsure about how to simply relax and enjoy being a dog. In a very short time, however, she has absolutely flourished.
Sadie Mae has come out of her shell, gained confidence, and started learning how to communicate with her foster family. She is making wonderful progress with potty training and is learning how to let her people know when she needs to go outside. She continues to grow more comfortable, curious, and affectionate as she settles into a safe routine.
Sadie Mae is looking for a patient, loving family that will continue helping her build confidence and enjoy all the good things life has to offer.
Please note that Sadie Mae has not yet been spayed. Her adoption will include a spay agreement requiring the procedure to be completed as soon as an appointment becomes available. Her adoption fee includes a refundable deposit that will be returned once proof of the completed spay is provided.

Otter has been well socialized and does great with other dogs, children, and cats. He is still learning to be respectful of feline friends, but he is making progress with continued guidance.
With a medium to high energy level, Otter enjoys staying active and especially loves spending time outside. Balls, stuffed animals, bones, sticks, and just about every other toy quickly become his favorites. He is happiest running, exploring, playing, and proudly carrying around whatever treasure he finds in the yard.
Otter also loves following his humans around and being included in their daily activities. After playtime, he is happy to settle in on the couch for snuggles.
In his foster home, Otter is working on potty training, kennel training, leash training, and basic obedience. He is very treat motivated and eager to learn, which makes training both fun and rewarding.

Edgar
Edgar
15 Weeks Old • Male • Mixed Breed
Edgar is a goofy, affectionate puppy with a big personality and an even bigger heart. While we do not know his exact breed mix, we expect him to grow into a large dog.
When Edgar first came into rescue, he was diagnosed with demodectic mange. This skin condition occurs when naturally present mites multiply excessively, often because a young puppy’s immune system is still developing. Demodectic mange is not contagious to people or other healthy animals, and Edgar has responded beautifully to veterinary treatment. His skin has healed, his coat continues to fill in, and he is ready to leave that chapter behind.
Edgar has been well socialized and does great with other dogs, children, and cats. His foster family describes him as the best big brother because he plays hard, loves hard, and sleeps hard.
He is both potty trained and kennel trained. Edgar is also working on his leash walking skills, although he currently prefers to take the lead and show everyone where the adventure should go.
With a medium energy level, Edgar enjoys playing with fluffy toys, collecting sticks, and finding every muddy spot available. He is playful, clever, and determined enough to figure out how to climb out of a puppy pen.
More than anything, Edgar loves being close to his people. He wants to follow his humans everywhere and would happily spend his days serving as their loyal shadow.
Edgar is looking for a family that will continue his training, include him in their daily adventures, and appreciate his goofy, loving personality.

When Annabelle first came into rescue, she and her siblings were diagnosed with demodectic mange.

Helen
Helen
15 Weeks Old • Female • Mixed Breed
Helen is the kind of puppy who has a way of making everyone feel special. Stretch out your arms, and she'll come running as fast as she can, ready to jump into a hug. She has a heart full of love, an irresistible personality, and a tail that doesn't just wag—it takes her whole body along for the ride.
And then there's her beard. Helen proudly sports the cutest little scruffy beard, earning her the title of our favorite "bearded lady." It's just one more thing that makes this sweet girl impossible not to fall in love with.
Helen's story started with a challenge. When she and her siblings first came into rescue, they were diagnosed with demodectic mange, a skin condition caused by naturally occurring mites that can multiply when a puppy's immune system is still developing. While it can look concerning, demodectic mange is not contagious to people or healthy pets. Thanks to excellent veterinary care, proper treatment, and lots of love, Helen has made an incredible recovery. Her skin has healed beautifully, her coat continues to fill in, and she's more than ready to begin the next chapter of her life.
Helen has been well socialized and does wonderfully with other dogs, children, and cats. She enjoys being part of the action but is just as happy soaking up affection from her favorite people.
She is already potty trained and kennel trained and is continuing to work on her basic obedience and manners in her foster home. Helen is eager to learn and responds well to positive reinforcement.
With a medium energy level, Helen is the perfect balance of playful and affectionate. She enjoys playing with soft, squishy toys, but her favorite moments are the simple ones—running into your arms for a hug or rolling over for belly rubs. If you're willing to blow raspberries on her belly, you'll quickly become one of her favorite humans.
Helen is looking for a family who will appreciate her gentle heart, her playful spirit, and her one-of-a-kind personality. In return, she'll offer unwavering loyalty, endless cuddles, and enough full-body tail wags to brighten even the toughest days.
