Meet Tootsie Roll Friendly, Playful, and Ready to Grow Up With His Forever Family Breed: Rat Terrier  Gender: Male | Age: 3/24/2026 Weight: 12 lbs currently (medium) Good With: Dogs ✔️ | Kids ✔️ | Cats: Unknown Personality: ❤️ Friendly | Playful | Happy | Curious Medical: ✔️ Vaccinations Current | Neuter: Pending at Age-Appropriate Time Location: Los Angeles, California Transportation: Ozzie and Friends Rescue coordinates safe transportation for approved adopters throughout the United States. ❤️ Personality & Breed Information Tootsie Roll is an adorable Terrier mix weighing approximately 12 pounds. He's a friendly young puppy who's ready to find a family to love and grow up with. At six months old, Tootsie Roll is at that fun in-between stage where he's no longer a tiny baby, but he's still very much a puppy. He has plenty of learning, exploring, playing, and growing ahead of him. His personality will continue to develop as he matures, and his future family will have the wonderful opportunity to help shape the adult dog he becomes. Tootsie Roll is good with other dogs and children, while his compatibility with cats is currently unknown. With a Terrier mix, Tootsie Roll may inherit a fun combination of traits. Retrievers are often social, affectionate, intelligent, playful, and people-oriented, while Terriers may bring curiosity, confidence, energy, and plenty of personality. Every mixed-breed dog is an individual, but Tootsie Roll's friendly nature is already shining through. He would benefit from: Daily age-appropriate walks and exercise Playtime and interactive toys Mental enrichment and games Positive-reinforcement training Continued positive socialization Consistent household routines Plenty of affection and family time He's looking for a family that understands puppies don't arrive knowing all the rules—they learn them through patience, consistency, and love. Puppy Training, Adjustment & What to Expect At six months old, Tootsie Roll is still learning about the world and what is expected of him. Rescue dogs may arrive with basic training at best, so his adopter should be prepared to continue working on: House training as needed Leash manners Basic commands Recall Appropriate chewing Calm greetings Household boundaries Positive socialization Building confidence Learning when it's time to settle and relax Puppies thrive with positive reinforcement, repetition, structure, and patience. Training should be a normal part of everyday life and an opportunity for Tootsie Roll and his family to build a strong relationship. 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 These are general guidelines rather than strict deadlines. Every dog adjusts differently, and Tootsie Roll should be given the time he needs. Owner Responsibilities & Veterinary Care Tootsie Roll's vaccinations are currently up to date for his age, and his neuter is pending until the appropriate age. Because he's still a puppy, his adopter should provide continued veterinary care and review his records with their veterinarian to determine when any remaining vaccinations or boosters are due and when neutering should be completed. His ongoing care should include routine wellness examinations, parasite prevention, dental care, quality puppy nutrition, healthy growth monitoring, grooming and nail care, appropriate exercise, and veterinary treatment whenever necessary. Because Tootsie Roll is still developing physically, exercise should remain age appropriate, avoiding excessive repetitive jumping or strenuous forced exercise while his body is growing. Adoption Information If you are interested in adopting Tootsie Roll, 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. Our goal is to give every dog the best possible chance of finding the right family and a home where they will be loved and cared for throughout their life. Adopting Tootsie Roll means committing to his training, veterinary care, safety, companionship, and happiness through puppyhood, adulthood, and eventually his senior years. Tootsie Roll is only six months old, and almost his entire life is still waiting to be written. He's friendly, young, and ready for all the walks, games, cuddles, adventures, and ordinary everyday moments that make a dog part of a family. Give Tootsie Roll the chance to grow up beside you, and you may just find your little puppy becoming your very best friend.September 23, 2026, 11:07 pm

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. You may be seeing our dogs listed in multiple states because we work hard to give as many of our rescue dogs as possible the opportunity to be seen by loving families beyond our local area. 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.

Story
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.
