Marilyn Monroe
Marilyn Monroe
9 Weeks Old • Female • Mixed Breed
📍 Fostered in Kenosha, WIMarilyn Monroe may be tiny, but she has all the star power of the icon she was named after.
This beautiful little girl has a way of capturing attention wherever she goes. With her sweet personality, intelligent mind, and undeniable charm, Marilyn has quickly become a favorite in her foster home. She may be young, but she already knows how to make an impression.
As for her breed mix, your guess is as good as ours. Her foster mom believes there may be some Coonhound or Plott Hound in her family tree, but whatever combination created Marilyn, we're convinced it was a good one.
Marilyn has been very well socialized and does wonderful with other dogs, children, and cats. She enjoys making new friends and approaches life with a happy, confident attitude. She has a medium energy level and loves spending her days playing, exploring, and learning new things.
When playtime rolls around, Marilyn can usually be found carrying around one of her favorite toys. Crinkly toys and squeaky toys are at the top of her list, and she takes her toy collection very seriously.
While her beauty may be what first catches your eye, it's her intelligence that truly stands out. Marilyn is incredibly smart and has been making fantastic progress with her training. She does well in a kennel, is very close to being fully potty trained, and already knows how to use a doggie door.

Hugh Hefner - Adoption Pending
Hugh Hefner
10 Weeks Old • Male • Mixed Breed
📍 Fostered in Kenosha, WIHugh Hefner may be the only boy in his litter, but he's handling the responsibility with plenty of charm, intelligence, and puppy-dog good looks.
Named after the famous bachelor himself, Hugh has spent his early weeks surrounded by a house full of sisters, and somehow he's managed to keep his cool through it all. While his namesake was known for a lavish lifestyle, this Hugh is much simpler—he's just looking for a loving family, a cozy place to nap, and a few squeaky toys to keep him entertained.
As for his breed mix, his foster mom believes he may have some Plott Hound or Coonhound in his family tree, but that's simply our best guess. Whatever breeds contributed to this handsome boy, they created a puppy who is both sweet and incredibly smart.
Hugh has been very well socialized and does wonderfully with other dogs, children, and cats. While he enjoys people, he can occasionally be a little unsure of himself in new situations. Fortunately, he gains confidence quickly when he has other dogs around him. His foster family has noticed that he truly thrives with canine companionship, and because of that, we believe he would do best in a home with another friendly dog.
One of Hugh's biggest strengths is his willingness to learn. He is highly food motivated, catches on quickly, and has already made impressive progress with his training. He is kennel trained, mostly potty trained, and already knows how to use a dog door. For a puppy his age, he's off to an amazing start.
When he's not learning new things, Hugh enjoys spending time playing with his favorite crinkly toys and squeaky toys. He has a medium energy level and enjoys a nice balance of playtime, exploration, and relaxation.
