Story
Hi, my name is Emmy! I`m a sweet senior lady looking for my perfect retirement home. I enjoy the quieter side of life and would love a calm, loving family to spend my golden years with. Because I can be a little sensitive when being handled, I`d do best in a home without young children who can respect my space. I`d also prefer to be the only dog in the home so I can soak up all the love and attention for myself. If you`re looking for a loyal companion to share cozy days and lots of love, I just might be the perfect match!

Story
Meet BowlenBowlen is a mellow, sweet senior boy who loves nothing more than cuddling and burrowing under blankets. He’d thrive with a family or a constant companion who can give him the extra love he adores. With slow, thoughtful introductions, he can enjoy canine friends—he previously loved snuggling with his dog brother!Bowlen needs an experienced owner familiar with leash and barrier reactivity. A meet-and-greet is required if there’s another dog in the home to help him feel comfortable.

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.

🐾 Meet Milo! 💙 Milo is a just over 2-year-old Jack Russell Terrier mix with a gentle heart and a quiet soul. New people and places can be a little overwhelming for him at first, but once he feels safe, his sweet personality begins to shine. Milo would thrive in a patient home that understands shy dogs and is willing to let him settle in at his own pace.
