Story
Meet Lia A Tiny Terrier With a Big Future and So Much Love to Give Breed: Rat Terrier Mix Gender: Female | Age: 3 Months DOB: July 10, 2026 (Estimated) Weight: 3.75 kg / 8 lbs Good With: Dogs ✔️ | Kids ✔️ | Cats: Unknown Personality: Playful | Curious | Sweet | Lively (Typical Puppy Traits) Medical: Vaccinations Current | Spay Status: Unknown | Microchip: Not Provided Location: Los Angeles, California Transportation: Safe transportation coordinated for approved adopters throughout the United States. ❤️ Personality & Breed Information Lia is an adorable 3-month-old Rat Terrier mix weighing approximately 8 pounds. This precious little girl is just beginning her journey through life, and she's looking for a loving family to help her grow into a happy, confident companion. At three months old, Lia is still very much a baby. She's at an important stage of development when everyday experiences, gentle guidance, and positive interactions can help shape her confidence and behavior as she grows. Rat Terriers are often known for being intelligent, curious, lively, affectionate, and full of personality. Despite their smaller size, they can be energetic little dogs who enjoy exploring, playing, and spending time with their families. As a Rat Terrier mix, Lia may develop some of these wonderful characteristics as she matures. She would benefit from a family that can provide age-appropriate playtime, gentle exercise, mental enrichment, positive socialization, and plenty of affection. Because Lia is still growing, her adult size cannot yet be determined from her current weight alone. With patience, consistency, and love, Lia has the opportunity to grow into a wonderful lifelong companion. Training, Adjustment & What to Expect At only three months old, Lia is still learning about the world. Her future family should be prepared for the normal responsibilities of raising a young puppy. Rescue dogs may arrive with basic training at best, so adopters should be ready to continue working on potty training, crate training if desired, leash walking, basic commands, recall, appropriate chewing, household boundaries, and positive socialization. Rat Terriers are often clever and eager to explore, so positive reinforcement, patience, repetition, and consistent routines will be especially important. Short, enjoyable training sessions will help Lia develop confidence while strengthening the bond she builds with her new family. Her adopter should also understand that puppies require supervision, structure, and time. Accidents, chewing, teething, and occasional mischief are all normal parts of puppyhood. Lia will need a family willing to invest the time and effort required to guide her through puppyhood and into adulthood. The 3-3-3 Rule 3 Days: Time to decompress and begin feeling safe. 3 Weeks: Time to understand her new household routine. 3 Months: Time to build trust, settle in, and begin feeling truly at home. These are guidelines rather than deadlines. Every rescue dog adjusts at their own pace, and Lia should be given the time she needs to feel safe and secure. Owner Responsibilities & Veterinary Care Lia's vaccinations are current, and her spay status has not yet been confirmed. Because she is only three months old, her adopter should review her medical records with a veterinarian to determine whether she needs additional puppy vaccine boosters, deworming, flea and parasite prevention, microchipping, or other preventive care. If Lia has not yet been spayed, her future family should discuss age-appropriate spaying with a veterinarian. As a growing puppy, Lia will need quality puppy nutrition, regular veterinary examinations, appropriate exercise, dental care, grooming, nail care, and continued preventive healthcare. Because she is still small and developing, her family should also provide safe play areas, gentle handling, and supervision around larger dogs or young children. Adopting a puppy is a long-term commitment that includes the time, financial responsibility, training, and care necessary throughout her life. Adoption Information If you are interested in adopting Lia, please complete an adoption application: 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 she will be loved and cared for throughout her life. Adopting Lia means committing to her training, veterinary care, exercise, safety, companionship, and happiness throughout her life. Lia may be tiny today, but she has a whole lifetime of love, adventures, and wonderful memories waiting ahead of her. At just three months old, she's looking for someone who will be there for every milestone, every new discovery, and every little victory. This sweet little Terrier deserves a family who will love her as she grows and give her the happy ending every puppy deserves.

Story
Kato is a springy, cuddly rat terrier puppy. He loves to spend time on his bed, go for walks, and run around in the backyard. His big ol' ears and attentive, eager-to-learn spirit help his good manners and training sessions. At just 6 months, he's already proven himself to be a well-minded, smart puppy, full of energy.Why do we need to rehome? We work demanding jobs and are not able to be home as often as Kato needs. Kato has some separation issues and needs more time than we can give to really helping him through that. We want to give him to family who can be there for him to train him through that, so that he can really thrive. His toys (including his favorite "Patch") and food will be included.

Story
Meet our adorable rat terrier puppy Rosa. She is around 5lbs and 5 months old.  Here is a video of Rosa and her sister Osoro:https://youtu.be/Felu2535QNA We don't know much about the background of Rosa or her sister Osoro. We do believe they are related even though they look quite different to each other. They are typical friendly and playful puppies, relatively confident around dogs of all sizes. They are a little vocal, especially around new dogs. They are comfortable being handled and are excited to see their foster parent however, they can be very shy and usually avoid being handled as best they can. The foster usually corrals them and scoops them up to crate them overnight. They sleep quietly through the night in their crate without any accidents. Their foster lets them out in the morning and they run riot in the backyard all day. With a little bit of human attention, they should quickly grow in confidence and seek out human affection. She is vaccinated, spayed and microchipped.  Rosa knows just how miraculous a turn her life has taken when she was picked out by Havok's Wolfpack and she is determined to live her new life to the fullest, hopefully, with you. Her adoption fee is $600. To submit an adoption application for her, head over to our website (please ignore the error code, the form will load correctly):http://www.havokswolfpack.com/adopt/ or you can use this link https://petstablished.com/adoption_form/18644/generic If your application is approved, we will contact you promptly. ##2867246##

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.
