We have owned Panda since she was a puppy and she is ~7 now. She is very sweet and great with people, kids, and other dogs. We need to rehome as she cannot be around our cat or chickens. She would be a fantastic dog for the right family.

Story
Meet Cassidy – A Loyal and Happy Lab/Collie/Shepherd Mix! DOB: 10/3/2022 | Weight: 76 pounds | Female Cassidy is a stunning Lab/Collie/Shepherd mix with a big heart and an even bigger personality. At 3 years old, she’s in the prime of her life—healthy, energetic, and full of love to give. Cassidy is known for her loyal spirit and happy demeanor. She absolutely adores her people, and with her affectionate nature, she’ll make a wonderful companion for an active and dedicated family. Breed Info: A mix of Labrador Retriever, Collie, and Shepherd, Cassidy combines intelligence, energy, and devotion. These breeds are known for their trainability and loyalty, but also for needing structure, exercise, and mental stimulation. Cassidy is a great candidate for agility work, hiking adventures, or simply being your best buddy in life. Special Notes: Cassidy is a spirited girl who loves to explore! She does have a talent for jumping fences, so she will require a home with a very secure, tall fence (or someone committed to leash walks and supervised play). She is currently enrolled in a basic training course and making wonderful progress. Continued training will be key to helping her thrive and channel her energy in positive ways. ‍‍ Owner Responsibilities: Cassidy’s new family will need to: Provide daily exercise and playtime. Continue with her training to reinforce good manners. Ensure a secure environment to keep her safe. Offer patience, structure, and plenty of love. &#226&#154&#150&#239&#184&#143 Things to Consider: Cassidy is best suited for an active household that can keep up with her energy. Landlords and property owners should be checked if you rent, as breed restrictions sometimes apply. Families should be prepared for her enthusiasm—she may not be best for homes with toddlers, but will love older children. The 3-3-3 Rule: Remember the adjustment period: 3 days to decompress. 3 weeks to learn your routine. 3 months to fully feel at home. Vet Care: Once adopted, getting Cassidy to your vet is important for a checkup and to establish ongoing care. &#226&#157&#164&#239&#184&#143 Why Cassidy Will Be a Great Addition: Cassidy isn’t just looking for a home—she’s looking for her forever partner. She has all the qualities of a best friend: loyal, protective, playful, and loving. With her happy spirit and willingness to learn, she’ll bring joy and companionship to the right home. She will thrive with someone who sees her spirited energy not as a challenge but as part of her charm. Cassidy is ready to love and be loved—could she be the one for you?

Story
I adopted Maisie from the Boulder Humane Society in November, 2021. She was 3-4 months old and had been picked up in New Mexico. She was on medication for anxiety and I was told she should be homed with another older dog and kept away from children. I live in a condo with a small deck area and I am very active outdoors so I thought that would be helpful to her anxiety. She exhibited aggressive behavior towards kids, cyclists and runners along trails so I took for to High Drive Training and we did the full training and advanced training and I was trained in how to use and ecollar. We also did Grumpy Growler Training through the Boulder Humane Society. She has gotten aggressive towards other dogs while she is on leash but off leash she is fine. She is afraid of thunderstorms and fireworks. When she is near children and they make sudden moves she does get aggressive. I am moving to be near my grand children so I need to rehome her to someone that has a yard and another dog hopefully.

Story
Sweet, loyal 10 year old border collie mix in need of a new home. Rocky has lived in Boulder with his people for 10 years, since being adopted as a puppy. Sadly his parents have both gone into care and can no longer look after him. Rocky has up to date vaccinations, loves long walks and swims and is happy in the car. He gets mild separation anxiety and thunderstorm anxiety and sometimes nips ankles due to his herding instinct. He has never bitten. He gets along with neutered adult dogs but should not be loose around puppies or children. He is in need of an experienced dog owner who will help him lose some weight and enjoy his final years. Rocky knows basic commands and walks well on a leash. He’s a very loving, sweet dog who will adore his new owners.

Story
Recently, our 9-month-old son was crawling past Marlin. Marlin gave a quick corrective nip/bite that unfortunately caught our son on the face. While it was clearly a boundary-setting response rather than a sustained or aggressive attack, it resulted in a facial injury. Given our son’s young age and mobility, we can no longer safely manage the household environment to prevent another incident. We feel strongly that Marlin deserves a home where he doesn't feel stressed by unpredictable infant behavior.

Story
Meet Hassan Breed: Husky / Kelpie Mix Sex: Male DOB: July 17, 2022 Weight: 66 pounds Health: Healthy and vaccinated Hassan is a striking, intelligent boy with soulful eyes and a strong, resilient heart. He was abandoned and rescued from a very busy roadway, where he was dangerously close to being hit by cars. Thankfully, he was saved in time — and now he’s ready for the safe, loving forever home he deserves. Despite his difficult beginning, Hassan has remained loyal, playful, and full of life. Personality Hassan lives peacefully with other dogs and enjoys being around humans. He loves going out for walks, running, and exploring the world around him. Playtime is one of his favorite things — especially chasing a ball or carrying around plush toys. When he first meets new people, Hassan can be a little reserved or cautious. But once he gets to know you, his personality softens beautifully, and he becomes affectionate and loyal. He just needs a little time to feel secure. Hassan does not like sharing his food, so he would do best in a home where feeding routines are managed thoughtfully and respectfully. Breed Info: Husky / Kelpie Mix This is a smart, athletic mix that typically brings: High intelligence and problem-solving ability Strong loyalty to their people Active energy that thrives with exercise A desire for engagement and purpose Hassan will do best in a home that enjoys walks, outdoor time, and mental stimulation. Owner Responsibilities Hassan will thrive with: Daily exercise (walks, running, play sessions) Continued positive reinforcement training Clear structure and consistency Managed feeding routines due to food guarding Patience while he builds trust with new people He is not difficult — he simply needs leadership, routine, and love. &#226&#154&#160&#239&#184&#143 Things to Consider Before Adopting Before bringing Hassan home, please consider: Do you have time for daily exercise and enrichment? Is your home and lifestyle stable long-term? Are pets allowed where you live? Can you provide structure and manage feeding separately if needed? Adoption is a lifelong commitment, especially for an active breed mix Hassan deserves a home that won’t give up on him. Vet Care Although Hassan is healthy and vaccinated, adopters should schedule a visit with their own veterinarian as soon as possible after adoption to establish care and continue his wellness routine. The 3-3-3 Rule First 3 days: Hassan may be cautious and observant as he adjusts. First 3 weeks: He’ll begin to learn your routine and feel secure. First 3 months: Trust deepens, and his loving, loyal personality truly shines. Patience and consistency will help him flourish. Why Hassan Is Special Hassan survived being abandoned and left in danger — yet he still chooses trust. He is playful, intelligent, and deeply loyal once he bonds. He deserves stability, safety, and someone who will show him that he is finally home for good. If you’re ready for an active, devoted companion who will stand by you with loyalty and heart, Hassan is waiting for you If you are interested in adopting this amazing dog, please follow the link https://www.ozzieandfriendsrescue.org/adoptions and fill out an application  Thank you for choosing Ozzie and Friends Rescue.

Maggie and Ollie are a bonded older duo looking to settle into a new home together! If you`re interested in opening your home and heart for two adorable pups instead of just one, these might be the pair for you. We`re even offering them at a 2-for-1 adoption price to help keep them together in their next home! They can be a bit reserved at first and will need time to transition out of the shelter, but with a little time, they blossom and let their sweet personalities shine! At this time, HSBV will only rehome them to a family either without children or with children over the age of 10.
