Meet Travis Friendly, Playful, and Ready to Grow Into Your Best Friend Gender: Male | DOB: January 18, 2026 | Weight: 40 lbs | Expected Size: Medium-Large Good With: Dogs ✔️ | Kids ✔️ | Cats: Unknown Personality: Playful | ❤️ Friendly | Social | Happy Medical: ✔️ Neutered | ✔️ Vaccinations Up to Date Location: Los Angeles, California Transportation: Ozzie and Friends Rescue coordinates safe transportation for approved adopters throughout the United States. ❤️ Personality & Breed Information Travis is a handsome 8-month-old Border Collie/Terrier mix who currently weighs about 40 pounds. He's a friendly, playful young dog with plenty of growing, learning, and loving still ahead of him. Travis is at such a fun age. He's no longer a tiny puppy, but he's still very much a youngster discovering the world. He'll need a family ready to enjoy his playful personality while also helping him develop into a well-mannered adult dog. Travis is affectionate, people-oriented, playful, loyal, athletic, and enthusiastic about spending time with their families. At 40 pounds at only eight months old, Travis should be considered a medium breed dog, although his exact adult weight cannot be guaranteed. His ideal family should be ready to provide him with: Daily walks and age-appropriate exercise Playtime and enrichment Positive-reinforcement training Continued socialization Consistent household rules and boundaries Mental stimulation Plenty of affection and family time Travis isn't looking for somewhere to simply finish growing—he's looking for the family he'll grow up with. Training, Adjustment & What to Expect At seven months old, Travis is entering adolescence, an important stage for continued training and social development. Rescue dogs may arrive with basic training at best, so adopters should be prepared to continue working on house training as needed, leash manners, basic commands, recall, calm greetings, appropriate play, and household boundaries. Because Travis is becoming a bigger, stronger dog, teaching good manners now will help set him up for success as an adult. Training should remain positive, consistent, patient, and rewarding. Young dogs need repetition, and mistakes are part of learning. The 3-3-3 Rule 3 Days to decompress and begin feeling safe 3 Weeks to understand his new household routine 3 Months to fully settle in, build trust, and feel at home Travis may be friendly and outgoing, but he still deserves time to adjust to his new surroundings and learn what is expected of him. Owner Responsibilities & Veterinary Care Travis is neutered and up to date on his vaccinations. His future family should continue routine veterinary wellness exams, recommended vaccine boosters, flea/tick/heartworm and parasite prevention, dental care, quality nutrition, healthy weight management, grooming and nail care, and veterinary treatment whenever needed. As a growing medium-large breed puppy, Travis should receive age-appropriate exercise and nutrition while his body continues developing. His veterinarian can help guide his family on healthy growth, body condition, diet, and exercise as he matures. Adoption Information If you are interested in adopting Travis, please complete an adoption application at: https://www.ozzieandfriendsrescue.org/adoptions Ozzie and Friends Rescue is a Los Angeles-based nonprofit dedicated to rescuing dogs in need and helping them find safe, loving forever homes. While based in Southern California, we coordinate safe transportation for approved adopters throughout the United States. Adopting a young dog like Travis means committing not only to the adorable puppy in front of you today, but also to the adult and senior dog he'll eventually become. Travis is friendly, playful, growing fast, and ready for his next chapter. Give him the training, adventures, security, and love every young dog deserves, and you'll get something pretty wonderful in return—the chance to watch your puppy grow into your lifelong best friend.October 4, 2026, 8:28 am

Story
Meet Cassidy – A Loyal and Happy Lab/Collie/Shepherd Mix! DOB: 10/3/2022 | Weight: 76 pounds | Female Cassidy is a stunning Lab/Collie/Shepherd mix with a big heart and an even bigger personality. At 3 years old, she’s in the prime of her life—healthy, energetic, and full of love to give. Cassidy is known for her loyal spirit and happy demeanor. She absolutely adores her people, and with her affectionate nature, she’ll make a wonderful companion for an active and dedicated family. Breed Info: A mix of Labrador Retriever, Collie, and Shepherd, Cassidy combines intelligence, energy, and devotion. These breeds are known for their trainability and loyalty, but also for needing structure, exercise, and mental stimulation. Cassidy is a great candidate for agility work, hiking adventures, or simply being your best buddy in life. Special Notes: Cassidy is a spirited girl who loves to explore! She does have a talent for jumping fences, so she will require a home with a very secure, tall fence (or someone committed to leash walks and supervised play). She is currently enrolled in a basic training course and making wonderful progress. Continued training will be key to helping her thrive and channel her energy in positive ways. ‍‍ Owner Responsibilities: Cassidy’s new family will need to: Provide daily exercise and playtime. Continue with her training to reinforce good manners. Ensure a secure environment to keep her safe. Offer patience, structure, and plenty of love. &#226&#154&#150&#239&#184&#143 Things to Consider: Cassidy is best suited for an active household that can keep up with her energy. Landlords and property owners should be checked if you rent, as breed restrictions sometimes apply. Families should be prepared for her enthusiasm—she may not be best for homes with toddlers, but will love older children. The 3-3-3 Rule: Remember the adjustment period: 3 days to decompress. 3 weeks to learn your routine. 3 months to fully feel at home. Vet Care: Once adopted, getting Cassidy to your vet is important for a checkup and to establish ongoing care. &#226&#157&#164&#239&#184&#143 Why Cassidy Will Be a Great Addition: Cassidy isn’t just looking for a home—she’s looking for her forever partner. She has all the qualities of a best friend: loyal, protective, playful, and loving. With her happy spirit and willingness to learn, she’ll bring joy and companionship to the right home. She will thrive with someone who sees her spirited energy not as a challenge but as part of her charm. Cassidy is ready to love and be loved—could she be the one for you?

This is Odin! He is a 9 year old Border Collie. Once he gets used to someone, he loves to be around them. Complete transparency, He is a reactive dog and will not get along with strangers. He has the following neurotic tendencies: Compulsive habits: Licking the floor or legs when stressed or feels he needs a "job", biting the closest thing to him (Furniture item, NOT people) Restlessness: consistent jumping at things in the air trying to "catch" them, and an inability to settle down and rest even after playing. Fixations: Staring intensely at walls or lights that are casted on walls/ items. Destruction: When stressed or in a "trace" he tends to bite or tear up furniture. He does not destroy any other items when not in this state. Vocalizing: Barking when scared or hears a delivery driver. He is such a handsome and sweet boy, he just needs someone that can give him more time and energy. He loves catching frisbees and cuddling close and he has the best "smile".

Story
I am EXCELLENT on walks, I have mastered "heel" and will walk beside my human the entire walk! My foster mom said that I put her dogs to shame with how well I do on my leash. I LOVE little dogs, I love playing tag with my foster dog brother (peekapoo) and sister (havanese). When I have encountered big dogs, I get scared and make my biggest bark possible. I don't trust big dogs yet, but hopefully I will find a friendly one that I can learn to trust. I am fully crate trained, I don't even cry when I go to bed, but I do struggle when asked to go to my crate (I need a little help with that). I am fully potty trained, and will let you know that I need to go out with a little squeak or bark. I love pedicures, my foster mom was shocked when she went to cut my nails and I just rolled over and relaxed while she did it. I am a total lover, physical touch is my love language, I will crawl onto your lap if you let me and love sitting beside my human watching the world go by. I absolutely love my walks, and my foster mom started running with me, I did 2 miles no problem yesterday on my leash! My foster mom said I would be an IDEAL running pup for someone. I am very smart and am eager to learn, I always listen and I thrive on positive reinforcement. I want to make my future parents very proud! I am very gentle with children, so far I have met and played with 3 year olds through 14 year olds. I am not skiddish, loud noises like the lawn mover, thunder and construction doesn't bother me. When I'm in the car, in my crate or home alone I calm right down if you play Calming Puppy Music on Spotify. ##2841946##

Wanda is the perfect combo - the legs of a giraffe, ears of a fox, and fur highlights any hairdresser would be proud of.  She is a sweet, sweet soul who is still learning to trust and settle in. She is a little uncertain on walks but is already starting to be more curious and comfortable - we mostly Wanda around. We move slowly and give her time, and she has been braver each day.  Patience and love are all she needs to let her relax into being a puppy again. She has made large strides each and every day. She could spend all day outside, watching the squirrels and birds, sniffing flowers and rolling in the grass. Potty training is a work in progress but we have already seen improvements. Very food motivated and responsive to any redirecting her away from things. She doesn't seem to have a mean bone in her body.  Don't you Wanda bring her home?! ##2841948##

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.

Meet Mr. Oreo Male Age: 7/23/2022 Weight: 42 pounds Breed: Australian Cattle / Catahoula Leopard mix  Neutered (Fixed): Yes Vaccines: Up to Date Microchipped Healthy & Adoption-Ready Personality, Breed Info & Expectations Mr. Oreo's life hasn't always been easy. At some point, the family he trusted was no longer able to care for him, and he found himself without the security of a home or the comfort of someone who loved him. Like so many wonderful dogs, he didn't understand why his world had suddenly changed. Yet through it all, Mr. Oreo never stopped believing that kindness still existed. When he arrived at our rescue, it didn't take long for everyone to fall in love with him. His tail wagged the moment someone spoke to him, and despite everything he had lost, he greeted each new day with hope instead of fear. Dogs like Mr. Oreo remind us that love can survive even the hardest chapters of life. Mr. Oreo is a loving, happy boy who simply enjoys being with people. He has a warm, affectionate personality and is happiest when he can be close to his family. Whether it's joining you for a morning walk, relaxing at your feet while you watch television, or greeting you at the door after work with a wagging tail, Mr. Oreo is the kind of dog who makes a house feel like a home. He has reached a wonderful stage in life where he is playful without being overly energetic. He enjoys getting outside for walks and adventures but is equally content spending quiet evenings cuddling with the people he loves. His calm, joyful personality makes him a wonderful companion for families, couples, or individuals looking for a loyal best friend. Mr. Oreo would thrive in a home prepared for: Daily walks and moderate exercise Plenty of love and companionship Positive reinforcement training Mental enrichment through toys and interactive activities Structure, consistency, and routine A lifelong commitment to his emotional and physical well-being Mr. Oreo has already experienced what it feels like to lose a home. Now he's hoping to find a family that will promise him something he's waited his whole life for—a forever home where he'll always be loved, always be safe, and never have to wonder if he's wanted again. Training, Adjustment & What to Expect Like many rescue dogs, Mr. Oreo may need a little time to adjust to a new home, routine, and environment. Even the happiest dogs benefit from patience as they learn where they belong. Mr. Oreo is eager to bond with his family and responds well to kindness, consistency, and positive reinforcement. Continuing his training and daily routine will help him settle in quickly and build confidence.

She was found starving and alone, trying to survive without her mother or anyone to protect her. At just seven weeks old, she should have been learning, playing, and feeling safe—not searching for food or shelter. Thankfully, rescuers stepped in before it was too late, giving Willow the chance to experience the love and care every puppy deserves. Today, Willow is a healthy, happy puppy whose joyful personality shines brighter every day. She has an affectionate heart and a playful spirit that's impossible not to love. She enjoys discovering new things, playing with toys, and bouncing around with puppy enthusiasm before happily settling down for cuddles. Willow loves people and enjoys being close to her family. She'll gladly follow you from room to room, eager to see what you're doing and hoping to be included in every adventure. Her sweet, trusting nature makes her an easy puppy to fall in love with. As an Australian Kelpie Mix, Willow is expected to grow into an intelligent, loyal, and energetic companion. Kelpies are highly trainable, eager to please, and thrive when given both mental and physical enrichment. With early socialization and positive reinforcement, Willow has everything she needs to become an incredible family dog. Willow would thrive in a home that offers: Plenty of love and companionship Positive reinforcement training Daily puppy playtime and exercise Interactive toys and mental enrichment Continued socialization A consistent daily routine A safe indoor home where she's treated as part of the family A lifetime of love, patience, and commitment Willow has already survived more than any puppy should have to face. Now she's ready to spend the rest of her life knowing what it feels like to be safe, loved, and truly home. Training, Adjustment & What to Expect Like all puppies, Willow is learning something new every day. Her new family should expect normal puppy behaviors such as chewing, teething, house-training, and plenty of curiosity. Please remember the 3-3-3 Rule: 3 Days to decompress and begin feeling safe 3 Weeks to learn your household routine 3 Months to fully settle into family life Willow will benefit from: Positive reinforcement training House-training and consistent routines Puppy-safe exercise and supervised play Continued socialization Enrichment activities and interactive toys Plenty of patience, love, and encouragement With guidance and consistency, Willow will grow into a confident, affectionate, and devoted companion. Owner Responsibilities & Veterinary Care Bringing home a puppy is a lifelong commitment that includes training, veterinary care, exercise, and companionship. Willow will need: Completion of her puppy vaccination schedule Spaying when age-appropriate Monthly flea, tick, and heartworm prevention A nutritious diet for healthy growth Daily exercise appropriate for her age Continued obedience training and socialization A safe, loving indoor home We recommend scheduling a wellness examination with your veterinarian shortly after adoption to establish care and ensure Willow continues to thrive.
