Story
Meet Nelson! This Collie mix is impossible to miss with his striking blue eyes and happy-go-lucky personality. After making the journey from a shelter in Kansas, Nelson is quickly learning that the good life is pretty great. Nelson is curious, playful, and always ready for his next adventure. He's a total rockstar on leash and loves getting out to explore and meet new people. Whether it's a neighborhood stroll, a mountain hike, or a trip to your favorite brewery patio, this boy is happy just being part of the fun. He's also doing great with potty training and is making progress with crate training. He sleeps in his crate overnight like a champ, though he'd definitely prefer to be wherever his people are. Super smart, goofy, and incredibly sweet, Nelson is the kind of puppy who will keep you laughing while stealing your heart at the same time. He's at the perfect age to continue learning, growing, and becoming your very best friend. All he needs now is a forever family ready to show him that life's greatest adventures are the ones shared together. Could Nelson be your new adventure buddy? ##2771090##

Story
Angle is a 4.5 Year Old Great Dane/Smooth Coated Collie Mix. She loves playing with other dogs and ignores cats, unless they want to play. She loves her people and even though she loves playing with other dogs, she really wants her human all to herself. She is also laid back and enjoys a good cuddle and chill on the couch while catching up on some TV. Angle is crate trained, enjoys toys and completely untrustworthy on free roam with high interest items (this includes expensive items; we don’t know how she knows – but she does!) If you think you are Angle's forever home, please complete an adoption application at https://www.savethegiants.com/adoption-process .

Erica is a 4.5-5 Month old with a big personality and an even bigger heart.

Story
Meet Hassan Breed: Husky / Kelpie Mix Sex: Male DOB: July 17, 2022 Weight: 66 pounds Health: Healthy and vaccinated Hassan is a striking, intelligent boy with soulful eyes and a strong, resilient heart. He was abandoned and rescued from a very busy roadway, where he was dangerously close to being hit by cars. Thankfully, he was saved in time — and now he’s ready for the safe, loving forever home he deserves. Despite his difficult beginning, Hassan has remained loyal, playful, and full of life. Personality Hassan lives peacefully with other dogs and enjoys being around humans. He loves going out for walks, running, and exploring the world around him. Playtime is one of his favorite things — especially chasing a ball or carrying around plush toys. When he first meets new people, Hassan can be a little reserved or cautious. But once he gets to know you, his personality softens beautifully, and he becomes affectionate and loyal. He just needs a little time to feel secure. Hassan does not like sharing his food, so he would do best in a home where feeding routines are managed thoughtfully and respectfully. Breed Info: Husky / Kelpie Mix This is a smart, athletic mix that typically brings: High intelligence and problem-solving ability Strong loyalty to their people Active energy that thrives with exercise A desire for engagement and purpose Hassan will do best in a home that enjoys walks, outdoor time, and mental stimulation. Owner Responsibilities Hassan will thrive with: Daily exercise (walks, running, play sessions) Continued positive reinforcement training Clear structure and consistency Managed feeding routines due to food guarding Patience while he builds trust with new people He is not difficult — he simply needs leadership, routine, and love. &#226&#154&#160&#239&#184&#143 Things to Consider Before Adopting Before bringing Hassan home, please consider: Do you have time for daily exercise and enrichment? Is your home and lifestyle stable long-term? Are pets allowed where you live? Can you provide structure and manage feeding separately if needed? Adoption is a lifelong commitment, especially for an active breed mix Hassan deserves a home that won’t give up on him. Vet Care Although Hassan is healthy and vaccinated, adopters should schedule a visit with their own veterinarian as soon as possible after adoption to establish care and continue his wellness routine. The 3-3-3 Rule First 3 days: Hassan may be cautious and observant as he adjusts. First 3 weeks: He’ll begin to learn your routine and feel secure. First 3 months: Trust deepens, and his loving, loyal personality truly shines. Patience and consistency will help him flourish. Why Hassan Is Special Hassan survived being abandoned and left in danger — yet he still chooses trust. He is playful, intelligent, and deeply loyal once he bonds. He deserves stability, safety, and someone who will show him that he is finally home for good. If you’re ready for an active, devoted companion who will stand by you with loyalty and heart, Hassan is waiting for you If you are interested in adopting this amazing dog, please follow the link https://www.ozzieandfriendsrescue.org/adoptions and fill out an application  Thank you for choosing Ozzie and Friends Rescue.

Story
Meet Maya – A Spirited Sweetheart Looking for Her Forever Home! Name: Maya Breed: Australian Kelpie–Terrier Mix DOB: December 7, 2024 Weight: 46 lbs  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. Breed Info – Australian Kelpie x Terrier: Australian Kelpies are highly intelligent, loyal working dogs with strong herding instincts. Terriers are energetic, clever, and full of personality. 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. With the right environment and care, Maya will blossom into your most loyal friend—one who makes you smile every single day. Maya is ready to run, play, and love her way into your life—are you ready to meet your new best friend?
