Meet Benito – Your Happy-Go-Lucky Adventure Buddy! Basic Info: Name: Benito Breed: Border Collie / Australian Cattle Dog Mix Sex: Male DOB: April 10, 2022 Weight: 46 lbs Intake Date: April 9, 2024 Personality – Happy, Playful & Full of Zest: Benito is pure sunshine on four paws! Always ready to play, explore, or lean in for a pet, he’s got an infectiously joyful personality that will keep a smile on your face. He loves interactive games, running around the yard, and getting belly rubs. Benito thrives on connection and fun—he’s a dog who wants to be in the middle of the action and part of the family. With him, every day is a new adventure. Breed Information: As a mix of Border Collie and Australian Cattle Dog, Benito is naturally intelligent, alert, and active. These working breeds are known for their stamina, loyalty, and sharp minds. Benito will benefit from regular physical exercise and mental stimulation to keep him balanced and happy. Puzzle toys, training sessions, and active play will help him shine. He’s eager to learn and eager to please! Owner Responsibilities: Provide daily exercise: walks, play, fetch, or dog sports Offer mental stimulation through training, puzzles, and games Use positive reinforcement training—Benito is smart and responsive Maintain regular veterinary care and vaccinations Ensure he’s part of the family, not left alone for long periods Provide structure, patience, and love Create a safe, indoor home environment Commitment for Life: Benito is not a short-term companion—he's a lifelong partner. Adopting him means committing to his care, well-being, and happiness for all of his days. He needs a family that understands that dogs are not disposable—they are forever. In return, Benito will give you loyalty, laughter, and love every single day. Do Not Leash Your Dog Outside Unattended: Benito should never be tied up or left outdoors alone. He needs companionship, safety, and interaction. Tethering a dog outside is not only dangerous but also deeply unfair to a social, intelligent dog like Benito. He deserves to be inside, where he can be close to his people and thrive. Why Adopt Benito? Because Benito brings joy wherever he goes. He’s playful without being overwhelming, smart without being stubborn, and affectionate without being clingy. He’s the perfect match for an active individual or family who wants a loyal sidekick with a big heart. Adopt Benito and experience the happiness of having a dog who truly loves life—and loves you.

Story
Meet Pilot! He is a young pup with a heart full of love and energy to spare. He’s a goofy, wiggly boy who is still very much a puppy—curious and always on the move. He has some classic herding-dog tendencies, like gentle nipping at hands when he’s excited, but he’s learning how to be polite and respectful in the home. He is dog friendly! He’s a fast learner and will make an awesome companion for someone active and willing to give him a little guidance and consistency. He’s been very sweet with everyone he’s met so far, though he can be a bit shy at first. He loves physical pets and melts for belly scratches. Pilot and Bria came from a hoarding situation in Texas, where there were 20 other dogs living in very difficult conditions. After being rescued, he had to fight hard at the start—but today he’s healthy and ready for a forever home. All POSO Dogs come with: - Spayed/Netuered - Basic Shots (age appropriate) - Fecal and tick disease testing - other medical concerns addressed before adoption - 2 Free one on one dog training sessions with a professional dog trainer - Training received in foster home - Basic things like some food, treats, leash and collar - PDFs of training material and local coupons and dog sitter recommendations

Story
Fenrir, nicknamed Fen, is an almost 4 year old border collie mix. He’s a very dependent boy and will let you know when he needs attention. He’s very active and loves to play with everyone. I have never seen him show any aggression to other dogs or people. He tends to jump up onto people especially new faces. My hopes for his new home is for one with active family members and someone with more time to give him and more love than he knows what to do with.

Story
Bruce is a 10-month-old puppy who’s funny, silly, and full of energy. He’s a little wild in a puppy way and absolutely loves being outside—running, exploring, and burning off energy. He would do best with someone who has a backyard and enjoys an active, outdoor lifestyle like hiking or long walks. This isn’t a rushed rehoming. I care deeply about Bruce and am looking for the right fit, not just any home. He deserves someone who can give him space, time, and a lot of love.

Dante is a sweet boy looking for love! He's likely to be an easy keeper and will enjoy neighborhood walks and relaxing in front of the TV at night. Dante is a wiz and loves to show off his tricks in exchange a treat! Dante knows sit, down, shake and more! As Dante has matured, he is less tolerant of impolite dogs, so at this time, we will only rehome him to a family where he will be the only dog, and we recommend older or no children.

Story
Meet Maya – A Spirited Sweetheart Looking for Her Forever Home! Name: Maya Breed: Australian Kelpie–Terrier Mix DOB: December 7, 2024 Weight: 30 pounds Spayed, Vaccinated, and Healthy About Maya: Maya is a beautiful, medium-sized girl with a bright mind and a playful heart. She’s active, friendly, and full of curiosity. Whether it’s chasing a ball, going for a walk, or exploring the backyard, Maya is always up for an adventure. She loves people and enjoys being part of the action—but when playtime is over, she’s happy to curl up near her favorite humans.

As a mix, Maya is the perfect blend of smart and spirited. She’ll thrive in a home that can provide both physical activity and mental stimulation. Expect a dog who learns quickly, bonds deeply, and loves to stay busy. Owner Responsibilities: Provide daily exercise (walks, playtime, or training games) Offer basic obedience training and positive reinforcement Feed a healthy diet and maintain regular veterinary care Include Maya in family life—she’s not a dog to leave alone or chained outside Keep her mentally and physically active to prevent boredom Provide love, patience, structure, and a sense of safety Things to Consider Before Adopting Maya: Time & Energy: Maya needs more than a quick potty break. She’ll do best with a person or family who is active and engaged. Finances: Dogs require ongoing expenses (food, vet visits, flea/tick prevention, grooming, toys, etc.). Housing Rules: Make sure your landlord allows pets—especially medium-to-large breeds. Allergies: Check for pet allergies in the household. Lifelong Commitment: Maya could live 12–15+ years. She’s not a temporary guest—she’s family. No Outdoor Chains or Isolation: Maya needs interaction, exercise, and affection. Leaving her tied outside is not safe or fair to her well-being. Why Maya Will Be a Great Addition: Maya is intelligent, affectionate, and ready to love her people with her whole heart. She’s great for active individuals, couples, or families who want a smart, loyal companion to join them on walks, hikes, or playtime in the yard.
