Making new best friends since 2024.

Meet Sebastian Lee

Age: 11 Weeks
Sex: Male
Breed: Mixed Breed
Location: Fostered in Pleasant Prairie, WI

Sebastian Lee is the kind of puppy who simply wants to be where his people are.

Whether he's following you around the house, relaxing at your feet, or curling up beside you for a nap, Sebastian finds comfort in being close to the people he loves. His affectionate personality and gentle nature make him an easy puppy to fall in love with.

Sebastian has been well socialized and gets along wonderfully with other dogs, cats, and children. He especially enjoys the company of other dogs and gains confidence from having a canine friend around. Because of that, we believe he would thrive in a home with another playful, friendly dog.

He has a calm, easygoing personality but is beginning to show more of his playful side as he grows and becomes more confident. Like any young puppy, Sebastian enjoys exploring the world, learning new things, and spending time with his family.

Sebastian is making excellent progress with his basic puppy training in his foster home and is eager to continue learning. After a day of playing, one of his favorite ways to unwind is by settling down with a good chew toy before snuggling up for a well-earned nap.

If you're looking for a loyal companion who wants to be part of every moment, Sebastian Lee is ready to become your newest best friend.

Adoption Fee: $450

Meet Checkers

Age: 9 Weeks
Sex: Female
Location: Fostered in Kenosha, WI
Litter: Game Night Litter
Suspected Breed: Golden Retriever/Black Mouth Cur Mix (plus a little mystery!)

If you're looking for a puppy who is equal parts adventurous and affectionate, Checkers is ready to make her move!

This sweet little girl has a gentle personality and loves spending time with both people and other animals. She's well socialized and gets along wonderfully with dogs, cats, and children, making her a fantastic addition to a variety of families.

As for her breed, we're making our best educated guess. We believe her mom has some Golden Retriever in her, and Checkers may have a little Black Mouth Cur somewhere in her DNA. Beyond that, it's anyone's guess—but whatever her mix may be, she's 100% adorable.

Checkers loves being outdoors, whether she's soaking up the sunshine, splashing in the water, or exploring the yard. She's also a big fan of treats and has yet to meet a toy she doesn't enjoy. After playtime, she's more than happy to curl up for some snuggles with her favorite people.

Checkers is still a young puppy, so she'll benefit from continued training, socialization, and plenty of positive experiences as she grows. With her loving personality and eagerness to be part of the action, she's sure to become a loyal and wonderful companion.

Adoption Fee: $450

Toto

Male | 11 Weeks Old | Believed to be a Poodle Mix

Fostered in Waukegan

Don't let his tiny size fool you—Toto has a personality that's larger than life!

This adorable 11-week-old boy is believed to be a Poodle mix and is looking for a family to call his own. He's a confident, curious little puppy who loves to stay busy. Whether he's carrying around one of his favorite chewy toys, exploring his surroundings, or entertaining himself with puppy antics, Toto is always finding a reason to have fun. And after all that excitement? He's more than happy to curl up for a well-earned nap.

Toto has been well socialized and gets along wonderfully with other dogs, cats, and children. His friendly, outgoing personality makes him an easy puppy to welcome into just about any home.

He's also a very smart little guy! While living with his foster family, Toto has been working on basic obedience, kennel training, leash walking, and potty training. He learns quickly and is eager to please, making him a wonderful candidate for continued training as he grows.

Toto currently has a medium energy level, though we expect him to become a bit more active as he gets older. He'll thrive with a family that enjoys spending time together, providing enrichment, and continuing to build on the great foundation he's already started.

If you're looking for a playful, affectionate companion who will keep you smiling every day, Toto could be the perfect addition to your family.

Tazz

Male | 16 Weeks Old | Pittie Mix

Fostered in Racine

If you're looking for a puppy who's always ready for fun, Tazz is ready to meet you!

This handsome 16-week-old Pittie mix has never met a toy he didn't love. Squeaky toys, balls, chew toys—you name it, Tazz is all in! He's an energetic, playful puppy who approaches every day with excitement and is always ready for his next adventure.

Tazz has been well socialized and gets along wonderfully with other dogs, cats, and children. Because he's an enthusiastic puppy with a high energy level and a playful style, we think he'd do best in a home with older children who can enjoy keeping up with all of his puppy fun.

He's not just adorable—he's smart, too. Tazz is currently working on his basic puppy training in his foster home and is making fantastic progress. He's doing well with potty training, is comfortable relaxing in his kennel, and continues to improve with his leash manners every day. With consistency and positive reinforcement, he's going to make an incredible lifelong companion.

After a full day of zoomies, games, and playing with his favorite toys, Tazz is more than happy to slow things down. His favorite place to be is cuddled up next to his favorite person, soaking up affection and handing out plenty of sweet puppy kisses.

Tazz is looking for an active family that will continue helping him learn, play, and grow into the amazing dog he's already becoming. If you're ready for a best friend who will keep you smiling and shower you with unconditional love, Tazz is waiting to meet you.

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.

Palmer June

Age: 11 Weeks
Sex: Female
Location: Pleasant Prairie, WI (Foster Home)

Palmer June is the kind of puppy who keeps life exciting.

With her gorgeous blue eyes and beautiful honey-colored coat, she's a head-turner everywhere she goes. While we've spent plenty of time trying to guess her breed mix, we're still not completely sure what she is—but we do know she's going to make one lucky family very happy.

Palmer June has been incredibly well socialized and loves having friends to spend her days with. Whether she's romping around with another dog, playing with children, or curling up beside someone for a cuddle, she's happiest when she's part of the action. She gets along wonderfully with other dogs, children, and cats.

She is kennel trained and is making excellent progress with both potty training and leash training. Palmer June is eager to learn and enjoys having opportunities to explore new things while building her confidence.

With a medium to high energy level, Palmer June is always ready for an adventure. She especially loves games of tug-of-war and has an impressive talent for turning just about anything into her next favorite tug toy.

Her foster mom affectionately calls her a "Sour Patch Kid," and it couldn't be more accurate. One moment she's zooming around the yard, bouncing through life like a tiny saber-toothed tiger, and the next she's covering you with kisses before curling up in your lap for a nap. It's this perfect balance of playful mischief and affectionate sweetness that makes her so special.

Although she's naturally curious about everything around her, Palmer June likes to stay close to her people while she takes it all in. Once she feels comfortable, she's ready to jump into the fun and make every day an adventure.

If you're looking for a smart, playful puppy with a big personality, an even bigger heart, and endless love to give, Palmer June could be the perfect addition to your family.

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

Breed: Black Lab Mix
Location: Fostered in Burlington, WI

Beauty is a smart, playful puppy with a huge personality and plenty of energy to share. At 13 weeks old, she is curious about everything, always ready to move, and looking for an active family that will include her in all of life’s adventures.

This beautiful girl has been very well socialized and does wonderfully with other dogs, children, and cats. She enjoys being part of the action and would thrive in a home where she receives plenty of interaction, exercise, and mental stimulation.

Beauty has a high energy level and is rarely completely still—even when she is sitting down! She loves exploring, playing, chewing on bones, and occasionally chasing a ball.

She is currently working on important puppy skills, including potty training, leash walking, and basic commands. Beauty is eager to learn and will benefit from a family committed to continuing her training with consistency and positive reinforcement.

Like many energetic puppies, Beauty is also learning to use her mouth appropriately during play. Her foster family jokingly calls her playful puppy bite an “alligator chomp.” She is making progress but will need continued guidance as she learns that people are not chew toys.

Beauty is a fun-loving firecracker who will keep her family laughing, moving, and on their toes. If you are looking for an intelligent, active companion who is always ready for the next adventure, she may be the perfect match.
