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
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
Meet Twotwo! Twotwo is an 8-year-old Rat Terrier weighing 25 pounds. This sweet boy can be a little shy at first, but once he feels comfortable, his gentle personality begins to shine. He especially enjoys treats, which can be a great way to help him feel comfortable and build a bond with his new family. Twotwo requires a home with another dog already present. Having a canine companion will provide him with companionship and help him feel more secure as he adjusts to his new surroundings. Twotwo also requires a securely fenced yard where he can safely enjoy outdoor time. His new family should be patient and willing to give him the time and positive experiences he needs to build confidence and settle into his new home. Twotwo has special medical needs related to a throat abnormality. Potential adopters will need to be aware of his medical needs and should review the Special Medical Needs information for additional details. Our team will be happy to discuss his condition and care needs with interested adopters during the adoption process. A required in-person meet and greet at our shelter is part of the adoption process to help ensure a good fit for Twotwo, his potential adopters, and any resident dogs. With patience, a canine companion, and a family willing to let him settle in at his own pace, Twotwo has the potential to become a wonderful and loving companion.

Story
Cami is a 12-year-old Rat Terrier weighing 18 pounds. This sweet senior girl is incredibly friendly and loves being around people. She enjoys soaking up attention and spending time with her favorite humans. Cami is dog selective and does best with dogs who respect her space, particularly around food and other resources. She tends to prefer more established, socially confident dogs who are comfortable giving her space and respecting her boundaries. Our Behavior Team will be happy to discuss Cami’s individual dog preferences and help determine what type of canine companion may be the best fit for her. Cami has recently mastered leash walking but is still working on her leash manners. She tends to get excited when out and about and sometimes has a hard time containing her enthusiasm. She no longer requires a fenced-in yard but would benefit from an adopter who has experience with dogs and is comfortable continuing to work with her on leash skills and manners. Cami would do best in a home without young children. She may be a better fit for a home with teenagers or young adults who can understand and respect her boundaries, especially around food and other resources. Cami is looking for a loving home where she can enjoy her golden years surrounded by companionship, attention, and all the affection she deserves. A required in-person meet and greet at our shelter is part of the adoption process to help ensure a good fit for Cami and her potential adopters. If you're looking for a sweet senior who loves people and has her own preferences when it comes to canine companions, Cami may be the perfect companion for you!

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.
