Due to circumstances beyond her control, her family made the difficult decision to surrender her to rescue. While it was a heartbreaking change, it also gave Roxy the opportunity to find a family that can offer her the lifelong stability, love, and commitment every dog deserves.

Whether she's joining you for a walk, playing with her favorite toys, or curling up beside you after a fun day, Roxy is happiest when she's spending time with the people she loves.

She's ready to give her whole heart to a family that will make her part of theirs forever. Training, Adjustment & What to Expect Moving into a new home is a major change for any rescue dog.

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 Roxy is intelligent and eager to please, making her an excellent candidate for continued positive reinforcement training.

Story
Meet Penguin Male DOB: May 19, 2023 Weight: 22 lbs Breed: Jack Russell Terrier / Rat Terrier Mix Neutered (Fixed) Vaccinated Microchipped Healthy & Adoption-Ready Personality, Breed Info & Expectations Penguin is an outgoing, friendly little guy with a fun personality and a big zest for life packed into a small body. He loves being around people, enjoys interaction, and carries himself with the confident, entertaining energy Terrier lovers know and adore. He has matured beautifully into a lively companion who still enjoys playtime and activity while also loving affection and companionship from his humans. Penguin thrives when he feels included and part of the action. As a Jack Russell Terrier / Rat Terrier mix, Penguin may show traits such as intelligence, curiosity, alertness, and playful energy. Both breeds are known for being highly engaging, clever little dogs who enjoy staying mentally and physically active. Penguin would thrive in a home that can provide: Daily walks and playtime Mental stimulation and engagement Structure and consistency Companionship and inclusion as part of the family He would make a wonderful companion for someone looking for a social, entertaining, and affectionate dog with lots of personality. Training, Adjustment & What to Expect Many rescue dogs come from very different backgrounds. Some may have previously lived in homes, while others may have come from the streets, overcrowded shelters, neglect situations, or environments where they had little structure or guidance. Because of this, most rescue dogs arrive with only basic training at best, and some may have had no formal training at all. Even dogs who appear well-behaved in foster care or at the rescue are still adjusting and learning. The rescue environment itself also does not always allow for extensive one-on-one training. While we work hard to provide safety, structure, socialization, and basic guidance, adopters should be prepared to continue training and support after adoption. Penguin will benefit from: Positive reinforcement training Structure and consistency Continued socialization and engagement Mental stimulation and routine Patience during adjustment periods Please remember the 3-3-3 Rule: 3 days to decompress 3 weeks to learn your routine 3 months to fully feel at home With patience, stability, and commitment, rescue dogs often blossom into deeply loyal lifelong companions. Owner Responsibilities & Veterinary Care Owning a dog is a lifelong commitment that includes daily exercise, companionship, routine veterinary care, training, mental stimulation, and financial responsibility. Penguin will need: Daily walks, exercise, and interaction Continued training and engagement Routine wellness exams and preventative veterinary care A safe, stable, indoor living environment Consistent veterinary care, proper nutrition, preventative care, and emotional stability are all essential to helping him live a healthy and happy life. Penguin is an indoor family dog and is not to be chained or left outside. Adoption Information If you are interested in adopting this wonderful dog, please complete an adoption application by visiting: https://www.ozzieandfriendsrescue.org/adoptions Thank you for considering adoption through Ozzie and Friends Rescue, a Los Angeles–based rescue dedicated to giving dogs a second chance at a loving home. Our team carefully reviews every application and will reach out to help match you with the right dog for your home and lifestyle.

While we are based in Los Angeles, we expand our reach throughout the Western United States and the Midwest to help more dogs find the forever homes they deserve. We understand that transportation and adoption fees can sometimes feel like a big commitment, and we truly appreciate every person who considers opening their heart and home to a rescue dog. Our goal is simply to give these dogs the best chance at being seen, adopted, and loved. Ozzie and Friends Rescue coordinates safe and reliable transport so adopted dogs can travel to their new homes across the Western United States, Canada, and the Midwest.

Meet George Goofy, Silly, and Full of Puppy Fun—George Is Ready for His Forever Family Breed: Chihuahua / Terrier Mix Gender: Male | Age: 06/13/2026 | Weight/Size: 7 lbs currently (small) Good With: Dogs ✔️ | Kids ✔️ | Cats: Unknown Personality: Goofy | Playful | Friendly | Silly | Puppy Personality Medical: ✔️ Vaccinations Current | Neuter: Age-Appropriate/Pending Location: Los Angeles, California Transportation: Ozzie and Friends Rescue coordinates safe transportation for approved adopters throughout the United States. ❤️ Personality & Breed Information George is an adorable 3-month-old Chihuahua / Terrier mix weighing approximately 7 pounds. This little guy is a goofy, silly puppy who brings plenty of fun and personality wherever he goes. He's at the perfect age for exploring, playing, learning, and figuring out the world around him. George is good with other dogs and children, while his compatibility with cats is currently unknown. As a Chihuahua / Terrier mix, George may grow into a bright, affectionate, curious, playful, and spirited companion. Both Chihuahuas and Terriers can pack a surprising amount of personality into a smaller body, and George is already showing that he's no exception! Because he is still very young, his exact adult size, appearance, energy level, and temperament cannot be guaranteed. George would love a family ready to enjoy his puppy antics while also giving him the structure, training, socialization, exercise, and companionship he needs to grow into a confident adult dog. Training, Adjustment & What to Expect George may be cute and tiny, but he's still a puppy who needs to learn all the important skills that come with being a family dog. His adopter should expect normal puppy behaviors such as potty accidents, chewing, puppy nipping, bursts of energy, curiosity, and plenty of goofy mischief. Rescue puppies generally arrive with basic training at best. George's family should be prepared to work on house training, leash skills, basic commands, recall, appropriate chewing, household boundaries, and continued positive socialization. Training should always be patient, consistent, and based on positive reinforcement. 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 George may be ready to have fun immediately, but he should still be given time to adjust at his own pace. Owner Responsibilities & Veterinary Care George's vaccinations are currently up to date, and his neuter will be completed when age appropriate. Because he is only three months old, his adopter should continue his puppy veterinary schedule and complete any remaining vaccinations and boosters recommended by his veterinarian. His future family should provide routine veterinary care, parasite prevention, quality puppy nutrition, dental care, age-appropriate exercise, continued training and socialization, and veterinary treatment whenever needed. As a small puppy, George should also be handled carefully and protected from rough play, unsafe jumps, open doors or gates, and interactions that could accidentally injure such a little dog. Adoption Information If you are interested in adopting George, 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 puppy means committing to George through every stage of his life—not only while he's tiny and adorable. He'll need continued training, veterinary care, patience, exercise, companionship, and lots of love. George is seven little pounds of goofy puppy personality. He's silly, playful, friendly, and ready to make his future family laugh for years to come. Give this little guy the chance to grow up knowing that he's loved, safe, and finally home.

Terriers often have fun personalities and enjoy exploring, playing, learning, and spending time with their people.

Training, Adjustment & What to Expect At only two months old, Jaime is truly a baby. His adopter should expect normal puppy behaviors such as potty accidents, chewing, puppy nipping, bursts of energy, curiosity, and plenty of learning. Rescue puppies generally arrive with basic training at best. His family should be prepared to work on: House training Crate training as appropriate Basic commands Leash skills when age appropriate Recall Appropriate chewing Bite inhibition Household boundaries Positive socialization Training should always be patient, consistent, and based on positive reinforcement.

His future family should provide routine veterinary care, parasite prevention, quality puppy nutrition, dental care, healthy weight management, age-appropriate exercise, continued training and socialization, and veterinary treatment whenever needed. Until his veterinarian confirms that his puppy vaccination series provides appropriate protection, his family should also be careful about exposing him to high-risk public areas where unknown or unvaccinated dogs may have been.

Story
Meet Rocky ❤️ Three Little Paws, One Very Big Heart—Rocky Is Ready for His Forever Family Breed: Jack Russell Terrier / Poodle Mix Gender: Male | Age: 6 years old | Weight/Size: 28 lbs (Small-Medium) Special Feature: Rocky has three legs Good With: Dogs ✔️ | Kids ✔️ | Cats: Unknown Personality: ❤️ Very Loving | Gentle | Sweet-Natured | Affectionate Medical: ✔️ Neutered | ✔️ Vaccinated Location: Los Angeles, California Transportation: Ozzie and Friends Rescue coordinates safe transportation for approved adopters throughout the United States. ❤️ Personality & Breed Information Rocky is a special Jack Russell Terrier / Poodle mix weighing approximately 26 pounds. This handsome boy may have only three legs, but he certainly isn't missing any love to give. Rocky is described as incredibly loving and noble, with a gentle and sweet nature. He's friendly with other dogs and good with children, making him a wonderful candidate for many different types of families. Being a three-legged dog doesn't mean Rocky can't enjoy a happy, active, and fulfilling life. Many tripod dogs adapt remarkably well and enjoy walks, exploring, playtime, and everyday family activities. His family simply needs to be thoughtful about his individual mobility and physical needs. Rocky's Jack Russell Terrier and Poodle heritage makes for a fun combination. Both breeds are known for being intelligent and highly trainable. Jack Russells tend to be lively, curious, playful, and adventurous, while Poodles are often affectionate, people-oriented, clever, and eager to learn. Rocky will benefit from activities that engage both his mind and body, while keeping his exercise appropriate for a three-legged dog. His ideal family will provide: Plenty of love and human companionship Daily exercise appropriate for his mobility Mental stimulation and interactive toys Positive-reinforcement training Continued socialization Comfortable places to rest A safe environment with good traction Regular grooming and coat maintenance Healthy weight management A secure indoor home where he's part of the family A lifelong commitment Most importantly, Rocky needs someone who sees the wonderful dog he is—not the leg he doesn't have. Training, Adjustment & What to Expect Rocky's future family should allow him time to become comfortable with his new surroundings and learn the household routine. Rescue dogs may arrive with basic training at best, so adopters should be prepared to continue working on house training, leash manners, basic commands, boundaries, and household routines as needed. Please remember 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 Because Rocky has three legs, his adopter should also pay attention to his physical comfort. Non-slip flooring, maintaining a lean and healthy weight, limiting unnecessary jumping, and providing appropriate exercise can help reduce excess stress on his remaining limbs and joints. Rocky doesn't need to be treated as fragile. He simply needs a family willing to understand his body and help him stay comfortable and active. Owner Responsibilities & Veterinary Care Rocky is already neutered and vaccinated. Because tripod dogs place additional demands on their remaining limbs, maintaining Rocky at a healthy weight will be particularly important throughout his life. His future family should provide: Routine veterinary wellness examinations Recommended vaccinations and boosters Flea, tick, heartworm, and parasite prevention Routine dental care Regular brushing and professional grooming as needed Quality nutrition and healthy weight management Exercise appropriate for his mobility Monitoring of his remaining legs, joints, and overall movement Mental stimulation and enrichment Continued positive-reinforcement training Veterinary treatment whenever illness or injury occurs A safe and comfortable indoor home If Rocky ever develops changes in his movement, activity level, or comfort, his family should have him evaluated by a veterinarian rather than assuming the change is simply related to being a tripod. Adoption Information If you are interested in adopting Rocky, please complete an adoption application at: https://www.ozzieandfriendsrescue.org/adoptions Thank you for considering adoption through Ozzie and Friends Rescue, a Los Angeles-based nonprofit dedicated to helping deserving dogs find safe, loving, permanent homes. Although we are based in Los Angeles, California, we coordinate safe and reliable transportation for approved adopters throughout the United States. Rocky may walk through life on three paws, but he has every bit as much love, personality, and joy to give as any other dog. He's loving, gentle, dog-friendly, kid-friendly, and ready for someone to see just how special he is. Rocky isn't looking for sympathy—he's looking for his family. ❤️September 17, 2026, 2:24 pm

At just a few months old, Benny was surrendered by his previous owner through no fault of his own. While losing the only home he had ever known was confusing, Benny has embraced his second chance with an open heart and a wagging tail. Now he's looking for a forever family that will love him for a lifetime. Benny is a cheerful, affectionate puppy who brings happiness wherever he goes. He loves meeting new people, exploring his surroundings, and playing with toys before settling in for cuddle time. His friendly personality and sweet nature make him easy to fall in love with. Curious and eager to learn, Benny enjoys discovering the world around him. Whether he's chasing after a ball, following you around the house, or curling up beside you for a nap, he's happiest when he's part of the family's daily adventures. As a Jack Russell Terrier / Shih Tzu Mix, Benny offers a wonderful blend of intelligence, playfulness, and affection. The Jack Russell side brings confidence, curiosity, and an energetic spirit, while the Shih Tzu contributes a loving, loyal, and people-oriented personality. With continued guidance and positive reinforcement, Benny is expected to mature into a devoted companion who enjoys both playtime and quiet moments with his family. Benny would thrive in a home that offers: Plenty of love and companionship Positive reinforcement training Daily puppy exercise and supervised playtime Interactive toys and mental enrichment Continued socialization with people and other dogs A consistent daily routine A safe indoor home where he's treated as a beloved member of the family A lifetime of love, patience, and commitment Benny's first family couldn't keep him, but that doesn't define his future. He's ready to find the family that will love him forever. Training, Adjustment & What to Expect Benny is still a young puppy and is in one of the most important learning stages of his life. Like all puppies, he'll need guidance as he learns house manners, basic obedience, and confidence in new situations. 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 Benny will benefit from: Positive reinforcement training House-training and consistent routines Puppy-safe exercise and supervised play Continued socialization with people and other animals Mental enrichment through toys, games, and training sessions Plenty of patience, encouragement, and love With consistency and gentle guidance, Benny will grow into a confident, well-mannered, and loyal companion. Owner Responsibilities & Veterinary Care Bringing home a puppy is a lifelong commitment that includes providing veterinary care, training, exercise, and plenty of love. Benny will need: Completion of his puppy vaccination schedule Neutering when age-appropriate Monthly flea, tick, and heartworm prevention A high-quality diet to support healthy growth Daily exercise and mental stimulation Ongoing 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 Benny continues to grow into a healthy, happy adult dog.
