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. Despite the transition, Roxy has remained the sweet, affectionate little girl she's always been. She has a gentle heart, a playful personality, and loves being around people. 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 is friendly, social, and gets along wonderfully with children, other dogs, and even cats, making her an excellent fit for many different households. Her easygoing nature and loving personality allow her to make friends wherever she goes. As a Chihuahua / Rat Terrier Mix, Roxy combines the loyal devotion of the Chihuahua with the intelligence, curiosity, and playful spirit of the Rat Terrier.

Roxy would thrive in a home that offers: Plenty of love and companionship Daily walks and playtime Positive reinforcement training Interactive toys and mental enrichment Continued socialization A consistent daily routine A safe indoor home where she's treated as a cherished member of the family A lifetime of love, patience, and commitment Although Roxy lost one home, she hasn't lost her ability to love. 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. Roxy may need a little time to adjust to unfamiliar surroundings, new routines, and different experiences. 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

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.
