He was part of a litter of puppies abandoned and left without food, shelter, or anyone to care for them.

Today, Pepino is a healthy, happy young dog with a cheerful personality that's impossible not to love. He has an affectionate heart, a playful spirit, and an endless curiosity about the world around him. Whether he's chasing a ball, exploring the backyard, or greeting everyone he meets with a wagging tail, Pepino approaches life with enthusiasm and joy.

Story
Meet Chiquis Found Wandering the Streets at Seven Years Old—Chiquis Is Ready to Spend Her Best Years Safe and Loved ❤️ Breed: Chihuahua Gender: Female | Age: August 13,2019 | Weight/Size: 13 lbs (Small) Good With: Dogs ✔️ | Cats: Unknown | Kids ✔️ Medical: Spay Status: Fixed | Vaccination Status: Current | Microchip Status: Not Provided Location: Los Angeles, California Transportation: Ozzie and Friends Rescue provides safe transportation to approved adopters throughout the United States. ❤️ Personality, Breed Information & Chiquis' Story No senior dog should have to wonder where she'll sleep at night. At approximately seven years old, Chiquis was found wandering the streets alone. We don't know how she ended up there or how long she had been on her own. She may once have had a family, but when she needed someone most, there was no one there to claim her. Thankfully, Chiquis was found and brought into rescue, where she could finally stop worrying about surviving and begin looking forward to something better. Chiquis is a sweet little Chihuahua who deserves the security of knowing that she belongs somewhere. At seven years old, she has left the hectic puppy stage behind, but she still has plenty of life ahead of her. She's ready for walks, companionship, cozy afternoons, and all those ordinary moments that become special when shared with a beloved dog. As a Chihuahua, Chiquis comes from a breed known for forming incredibly strong bonds with their people. Chihuahuas are intelligent, loyal, alert, and affectionate companions. They may be small, but their personalities and devotion to their families can be enormous. Chiquis would thrive in a home that offers: Plenty of affection and companionship Daily walks appropriate for her age A comfortable place to rest and relax Positive reinforcement and gentle guidance A predictable daily routine Mental enrichment and interactive play A safe indoor home where she's included in family life Regular veterinary care as she enters her senior years Most importantly, a family committed to loving her for the rest of her life Chiquis has spent enough time wondering where she belongs. Her next chapter should be about knowing exactly where home is. Training, Adjustment & What to Expect Even mature dogs need time to adjust after adoption. Chiquis will be learning a completely new environment, schedule, and family. Please remember the 3-3-3 Rule: 3 Days to decompress and begin feeling safe 3 Weeks to understand her new household routine 3 Months to settle in, build trust, and truly feel at home Being seven doesn't mean Chiquis can't continue learning. Adult and senior dogs can respond beautifully to positive reinforcement training, especially when they're given patience and consistency. Her new family should allow her to adjust at her own pace while providing gentle boundaries, regular exercise, enrichment, and plenty of opportunities to bond. Owner Responsibilities & Senior Veterinary Care At approximately seven years old, Chiquis is entering her senior years. Preventative veterinary care becomes increasingly important during this stage of life. Her adopter should be prepared to provide: Regular veterinary wellness examinations Senior bloodwork and health screenings as recommended Routine vaccinations Flea, tick, heartworm, and parasite prevention Routine dental examinations and dental care A nutritious diet appropriate for her age and size Weight management Daily exercise appropriate for her health and mobility Mental stimulation and enrichment Veterinary care whenever illness or injury occurs A warm, comfortable, safe indoor home Senior dogs can have many wonderful years ahead of them. Consistent preventative care can help identify age-related changes early and keep Chiquis comfortable, active, and happy. Adoption Information If you are interested in adopting Chiquis, 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 giving deserving dogs a second chance at loving, permanent homes. Although we are based in Los Angeles, California, we proudly coordinate safe and reliable transportation for approved adopters throughout the United States. Chiquis was found wandering the streets at an age when she should have already had a home to grow old in. She can't tell us where she's been, but we can help decide where she goes next. She deserves a warm bed, gentle hands, daily companionship, and a family who will make sure she never has to wander alone again. ❤️August 27, 2026, 10:04 am

Story
Meet Rubi Female Weight: 28 pounds current Breed: Chi / Terrier Mix Expected Size: Medium when fully grown Spayed (Fixed): Vaccines: In Progress Microchipped Healthy & Adoption-Ready Personality, Breed Info & Expectations Rubi is a sweet, affectionate puppy with a loving personality and playful spirit. She enjoys spending time with her people, exploring her surroundings, and soaking up all the attention and affection she can get. Like many puppies, she is curious about the world and excited to learn new things every day. Rubi has intelligence, loyalty, athleticism, and a strong desire to bond with her family. Black Mouth Cur mixes are often known for their devotion and eagerness to please, while Terriers bring curiosity, confidence, and playful energy. Rubi is expected to mature into a small adult dog. Rubi would thrive in a home prepared for: Ongoing puppy training and supervision Daily exercise, playtime, and enrichment Positive socialization experiences Structure, consistency, and routine A lifelong commitment to her physical and emotional well-being Puppies are adorable, but they are also a major responsibility that requires patience, training, supervision, and long-term commitment. Training, Adjustment & What to Expect Many rescue puppies come from uncertain beginnings and may not have had structure, socialization, or training before arriving at rescue. Even very young puppies require guidance and supervision to learn how to become confident, well-mannered adult dogs. Puppies are not automatically trained simply because they are young. While we work hard to provide safety, care, and basic socialization, adopters should expect to continue all training and development after adoption. Adopting a puppy means being prepared for: Potty training and accidents Teething and chewing phases Crate training and leash training Nighttime wakeups and supervision Jumping and playful puppy behavior Continued socialization and confidence-building Daily exercise and enrichment Routine veterinary visits and vaccine boosters Financial commitment throughout the dog's lifetime Rubi will benefit from: Positive reinforcement training Daily structure and routine Continued socialization and exposure Mental stimulation and enrichment Patience, consistency, and supervision 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, guidance, and commitment, puppies like Rubi grow into wonderful lifelong companions. Owner Responsibilities & Veterinary Care Owning a puppy is a lifelong commitment that includes training, exercise, routine veterinary care, financial responsibility, and emotional commitment throughout every stage of life. Rubi will need: Ongoing puppy training and guidance Routine veterinary visits and vaccine boosters Preventative care including flea, tick, and heartworm prevention Proper nutrition and growth monitoring Daily exercise, enrichment, and companionship A safe, stable, indoor living environment Puppies require regular veterinary care throughout their first year, including booster vaccines, wellness exams, and spay surgery when age-appropriate. Because Rubi is still young and growing, adopters should be prepared for the normal puppy stages that include chewing, teething, accidents, testing boundaries, and continued social development. Rubi is an indoor family dog and is not to be chained or left outside. Adoption Information If you are interested in adopting this wonderful puppy, 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.

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. Her new family should continue providing: Positive reinforcement training Daily exercise and interactive play Consistent routines and gentle structure Continued socialization with people and other animals Mental enrichment through toys and games Plenty of love, patience, and encouragement With kindness and consistency, Roxy will quickly blossom into a loyal, confident companion who will happily share life's adventures by your side.

Story
Meet Chiquis Found Wandering the Streets at Seven Years Old—Chiquis Is Ready to Spend Her Best Years Safe and Loved ❤️ Breed: Chihuahua Gender: Female | Age: August 13,2019 | Weight/Size: 13 lbs (Small) Good With: Dogs ✔️ | Cats: Unknown | Kids ✔️ Medical: Spay Status: Fixed | Vaccination Status: Current | Microchip Status: Not Provided Location: Los Angeles, California Transportation: Ozzie and Friends Rescue provides safe transportation to approved adopters throughout the United States. ❤️ Personality, Breed Information & Chiquis' Story No senior dog should have to wonder where she'll sleep at night. At approximately seven years old, Chiquis was found wandering the streets alone. We don't know how she ended up there or how long she had been on her own. She may once have had a family, but when she needed someone most, there was no one there to claim her. Thankfully, Chiquis was found and brought into rescue, where she could finally stop worrying about surviving and begin looking forward to something better. Chiquis is a sweet little Chihuahua who deserves the security of knowing that she belongs somewhere. At seven years old, she has left the hectic puppy stage behind, but she still has plenty of life ahead of her. She's ready for walks, companionship, cozy afternoons, and all those ordinary moments that become special when shared with a beloved dog. As a Chihuahua, Chiquis comes from a breed known for forming incredibly strong bonds with their people. Chihuahuas are intelligent, loyal, alert, and affectionate companions. They may be small, but their personalities and devotion to their families can be enormous. Chiquis would thrive in a home that offers: Plenty of affection and companionship Daily walks appropriate for her age A comfortable place to rest and relax Positive reinforcement and gentle guidance A predictable daily routine Mental enrichment and interactive play A safe indoor home where she's included in family life Regular veterinary care as she enters her senior years Most importantly, a family committed to loving her for the rest of her life Chiquis has spent enough time wondering where she belongs. Her next chapter should be about knowing exactly where home is. Training, Adjustment & What to Expect Even mature dogs need time to adjust after adoption. Chiquis will be learning a completely new environment, schedule, and family. Please remember the 3-3-3 Rule: 3 Days to decompress and begin feeling safe 3 Weeks to understand her new household routine 3 Months to settle in, build trust, and truly feel at home Being seven doesn't mean Chiquis can't continue learning. Adult and senior dogs can respond beautifully to positive reinforcement training, especially when they're given patience and consistency. Her new family should allow her to adjust at her own pace while providing gentle boundaries, regular exercise, enrichment, and plenty of opportunities to bond. Owner Responsibilities & Senior Veterinary Care At approximately seven years old, Chiquis is entering her senior years. Preventative veterinary care becomes increasingly important during this stage of life. Her adopter should be prepared to provide: Regular veterinary wellness examinations Senior bloodwork and health screenings as recommended Routine vaccinations Flea, tick, heartworm, and parasite prevention Routine dental examinations and dental care A nutritious diet appropriate for her age and size Weight management Daily exercise appropriate for her health and mobility Mental stimulation and enrichment Veterinary care whenever illness or injury occurs A warm, comfortable, safe indoor home Senior dogs can have many wonderful years ahead of them. Consistent preventative care can help identify age-related changes early and keep Chiquis comfortable, active, and happy. Adoption Information If you are interested in adopting Chiquis, 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 giving deserving dogs a second chance at loving, permanent homes. Although we are based in Los Angeles, California, we proudly coordinate safe and reliable transportation for approved adopters throughout the United States. Chiquis was found wandering the streets at an age when she should have already had a home to grow old in. She can't tell us where she's been, but we can help decide where she goes next. She deserves a warm bed, gentle hands, daily companionship, and a family who will make sure she never has to wander alone again. ❤️August 27, 2026, 10:04 am

Story
Meet Rubi Female Weight: 28 pounds current Breed: Chi / Terrier Mix Expected Size: Medium when fully grown Spayed (Fixed): Vaccines: In Progress Microchipped Healthy & Adoption-Ready Personality, Breed Info & Expectations Rubi is a sweet, affectionate puppy with a loving personality and playful spirit. She enjoys spending time with her people, exploring her surroundings, and soaking up all the attention and affection she can get. Like many puppies, she is curious about the world and excited to learn new things every day. Rubi has intelligence, loyalty, athleticism, and a strong desire to bond with her family. Black Mouth Cur mixes are often known for their devotion and eagerness to please, while Terriers bring curiosity, confidence, and playful energy. Rubi is expected to mature into a small adult dog. Rubi would thrive in a home prepared for: Ongoing puppy training and supervision Daily exercise, playtime, and enrichment Positive socialization experiences Structure, consistency, and routine A lifelong commitment to her physical and emotional well-being Puppies are adorable, but they are also a major responsibility that requires patience, training, supervision, and long-term commitment. Training, Adjustment & What to Expect Many rescue puppies come from uncertain beginnings and may not have had structure, socialization, or training before arriving at rescue. Even very young puppies require guidance and supervision to learn how to become confident, well-mannered adult dogs. Puppies are not automatically trained simply because they are young. While we work hard to provide safety, care, and basic socialization, adopters should expect to continue all training and development after adoption. Adopting a puppy means being prepared for: Potty training and accidents Teething and chewing phases Crate training and leash training Nighttime wakeups and supervision Jumping and playful puppy behavior Continued socialization and confidence-building Daily exercise and enrichment Routine veterinary visits and vaccine boosters Financial commitment throughout the dog's lifetime Rubi will benefit from: Positive reinforcement training Daily structure and routine Continued socialization and exposure Mental stimulation and enrichment Patience, consistency, and supervision 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, guidance, and commitment, puppies like Rubi grow into wonderful lifelong companions. Owner Responsibilities & Veterinary Care Owning a puppy is a lifelong commitment that includes training, exercise, routine veterinary care, financial responsibility, and emotional commitment throughout every stage of life. Rubi will need: Ongoing puppy training and guidance Routine veterinary visits and vaccine boosters Preventative care including flea, tick, and heartworm prevention Proper nutrition and growth monitoring Daily exercise, enrichment, and companionship A safe, stable, indoor living environment Puppies require regular veterinary care throughout their first year, including booster vaccines, wellness exams, and spay surgery when age-appropriate. Because Rubi is still young and growing, adopters should be prepared for the normal puppy stages that include chewing, teething, accidents, testing boundaries, and continued social development. Rubi is an indoor family dog and is not to be chained or left outside. Adoption Information If you are interested in adopting this wonderful puppy, 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.

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.
