Story
I have had Olaf since he was a puppy! It actually breaks my heart to write this request as he is such an amazing (but quirky) little guy. Olaf is a 12 year old rat terrier with a beautiful Merle coat and big personality! He loves to cuddle, be around his people, and sunbathe! He is friendly with cats but is a bit dog aggressive / territorial. He loves people but gets spooked easily/ does not like to be picked up. He does love to hop up and sit in your lap (just on his own terms). Unfortunately, Olaf bit our toddler this summer and we just welcomed a new baby into our home. We have had to keep him sectioned off from our toddler since July and now with our baby girl, it’s just too much. We want him to have a fun and free few years of his life left. We can’t offer him what he deserves :( I think he would be such a great companion for a home without dogs / kids! He is an easy keep and does well being left home alone!

Story
Bunnie is a smart, energetic, and silly 13 month old puppy. I adopted her from Animal Friends Alliance at 10 months old, and, though I love her, it's become clear that my home isn't the best fit. She and our cat have not adjusted to each other well, and my work schedule makes providing her with enough exercise and stimulation difficult. She knows basic commands and a few tricks, and she is very food motivated. Bunnie loves other dogs, particularly larger ones, but she can be a bit of a bully with smaller and more nervous dogs. She loves to play with toys and chew on bully sticks, and she adores people. Running is her favorite activity, and she's fast! When she's calm, she's very cuddly.Bunnie would do best in a home without cats, since she chases them, and she barks at children. She is about 90% on housebreaking. She gets mouthy when excited.Bunnie would be a great running/hiking buddy, and she'd do well with a doggy friend. I'd be happy to have her food and toys go with her

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.
