Story
Meet Nelson! This Collie mix is impossible to miss with his striking blue eyes and happy-go-lucky personality. After making the journey from a shelter in Kansas, Nelson is quickly learning that the good life is pretty great. Nelson is curious, playful, and always ready for his next adventure. He's a total rockstar on leash and loves getting out to explore and meet new people. Whether it's a neighborhood stroll, a mountain hike, or a trip to your favorite brewery patio, this boy is happy just being part of the fun. He's also doing great with potty training and is making progress with crate training. He sleeps in his crate overnight like a champ, though he'd definitely prefer to be wherever his people are. Super smart, goofy, and incredibly sweet, Nelson is the kind of puppy who will keep you laughing while stealing your heart at the same time. He's at the perfect age to continue learning, growing, and becoming your very best friend. All he needs now is a forever family ready to show him that life's greatest adventures are the ones shared together. Could Nelson be your new adventure buddy? ##2771090##

Story
Angle is a 4.5 Year Old Great Dane/Smooth Coated Collie Mix. She loves playing with other dogs and ignores cats, unless they want to play. She loves her people and even though she loves playing with other dogs, she really wants her human all to herself. She is also laid back and enjoys a good cuddle and chill on the couch while catching up on some TV. Angle is crate trained, enjoys toys and completely untrustworthy on free roam with high interest items (this includes expensive items; we don’t know how she knows – but she does!) If you think you are Angle's forever home, please complete an adoption application at https://www.savethegiants.com/adoption-process .

Story
Adoption Fee: $475 When available, all animals are fixed in accordance with Colorado law, up to date on vaccines (may need boosters), and microchipped! What we know: Single 4-month-old female owner surrender transferred from Española Humane Society in New Mexico. Adopted from CPR in April 2026, returned because the family realized they did not have time with her and she was not adjusting well to their cats. Originally named Sabrina. From the foster: Meet Sabrina! If you’re looking for a fun-loving, active companion, Sabrina may be your perfect match! At just 6 months old, this adorable Border Collie mix is full of enthusiasm, curiosity, and affection. Sabrina is a very high-energy puppy who thrives when she has plenty of physical exercise and mental stimulation. She’ll do best with a family that can provide daily activity, playtime, and opportunities to learn. Because she’s happiest being busy, Sabrina would love a home where her people are home much of the time and can include her in their daily lives. One of Sabrina’s favorite things is playing with other dogs! She gets along wonderfully with canine companions and would likely enjoy having a playful dog sibling or regular opportunities for doggy playdates. She has loved the local dog park and would stay and play all day if she could. She’s already off to a great start with her training—Sabrina is crate trained, sleeping beside her people quietly for 8 hours a night. She walks nicely on a leash and when it’s time to play, you’ll usually find her happily chewing on a favorite toy or chasing a tennis ball with endless enthusiasm. Sabrina has not yet been tested with cats since returning to foster, but she has been wonderful with adults. If you’re an active person or family looking for a smart, affectionate puppy to share your adventures, Sabrina is ready to bring joy, laughter, and lots of tail wags into your life. With continued training, plenty of exercise, and lots of love, she’s sure to grow into an incredible lifelong companion. www.coloradopuppy.org/how-to-adopt

Story
Adoption Fee: $475 When available, all animals are fixed in accordance with Colorado law, up to date on vaccines (may need boosters), and microchipped! What we know: Litter of 10 puppies, originally part of a litter of 14, found at approximately 2 months old in Texas. While in the care of another rescue, the litter slowly began breaking with parvo and sadly 3 puppies ultimately passed away. One puppy was transferred to another rescue, while the remaining 10 puppies were transferred into our care at approximately 4.5–5 months old. **Cassie will be available through private meet and greets only to set her up for success. Please email info@coloradopuppy.org with questions or to set up a meet and greet** Cassie has successfully completed a three-week board-and-train program with Art of the Dog Canine Academy. During her time there, she learned foundational obedience skills, improved her ability to remain neutral in distracting and stressful environments, and developed tools to better navigate situations that were previously challenging for her. To continue building on her progress, it is important that Cassie’s training remains consistent in her adoptive home. She has been trained using an e-collar as part of her training program and is comfortable working with this system. Her adopters should be prepared to continue the training methods she has learned to provide consistency and help set her up for long-term success. As part of Cassie’s adoption, Art of the Dog Canine Academy has generously offered her adopters complimentary lifetime follow-up training sessions. This resource is strongly encouraged to help ensure a smooth transition and continued progress. Based on her trainers’ recommendations, Cassie will do best in a calm, low-stress home without children. She would do well with a compatible canine companion but is not considered an appropriate candidate for dog parks or other high-stimulation environments. Her adopters should be committed to maintaining her training and providing the structure and consistency that will allow her to continue thriving. *Cassie was returned because she was going after the children in the home, even after repeated training efforts. She will require a home with no children. She also reportedly went after the man in the home. She was great with the previous adopters' dogs.* From the foster: If Cassie has pulled at your heart, know her story evolving and I’ll keep her updates coming. The first thing, and it’s the most important, Cassie has a big heart, a big loving, full of ‘do you love me?’ love bursting out of her jumbo size puppy body. This is a big puppy! Her motivation is love more than treats. She loves to be love, loves words of affirmation. If your other dog is getting love, she’ll come to your other side because 🥰 equal loving 🥰. ‘We share the love and attention.’ So you may get dual action simultaneous face licks! Cassie wants to give you love as a puppy, she’s learning what you consider okay. 🐾 Cassie was in an excellent intensive board & train program, not a home or playing with dogs, so back in our home, she’s learning how to incorporate her training into home things. For foster mom, we can cuddle but you can’t stand on me and lick in my mouth. [because ew gross!] Art of the Dog gave me the tools to modify that behavior. Cassie is a huge goofy puppy that can’t simply be pushed off you, she just takes it as a nudge then comes back with the lick and oh yeah, now dog hair is in your mouth too. Cassie has been rocking her continued training. Her heel is fantastic and weaves through all her training and trust. Know that Cassie is a smart girl and will test you to see if you’ll hold her accountable. Our first days back together have been tests. Accountability is key (if this makes you uncomfortable, Cassie isn’t the one but it’s okay, CPR has so many who need homes). Coming back to our home, that didn’t have all these rules before, meant keeping to Art of the Dog training ques and rules. As her foster, I needed to know ‘tapping’ her wouldn’t damage her emotionally when she was testing me on holding her accountable. This is where Art of the Dog came to rescue. I was in a meltdown, am I hurting her? Why is she suddenly acting like her bed is a fiery pit in hell? She’s still a toddler in 60lb body, so she dropped to the ground like a limp noodle and wasn’t having it. What am I supposed to do? I can’t get her on, I’m zapping, she’s now hiding, and I’m crying. What am I doing wrong? What should I be doing? Am I hurting her? Everyone, including my own dogs was upset. Art of the Dog was there for me. 100%. I was told they were there to help, ‘but can you trust that? Yes, you can’. They were kind and understanding, listened to everything before offering a solution, which was shockingly simple. Guide to her bed with her specific lead. Yep, she walked right up and laid down and stayed. Stayed while I cooked (one of Cassie’s rules is she need rest on her bed “place” while I’m cooking & vacuuming to enforce good doggie manners), she stayed while her foster siblings bolted out the doggie door to bark. Stayed without a single correction until I released her. Art of the Dog laid a solid foundation. I need to learn to speak her language. AOD is there. In addition to giving me their time, they sent me videos for homework. Know the people there genuinely want your dog to have success. Cassie is staying in a home with the happiest 80lb Golden and friendliest 40lb Rescue (that can hold his own in a rough & tumble game.) Cassie is still a puppy, a puppy that wants to play, but she is strong and is learning play manners. Art of the Dog gave me the tools to correct playtime when she’s not reading her playmates cues. Cassie is great with her foster brother and sister, sleeping, eating, walking and playing together but that doesn’t mean we didn’t have fights. That’s when Art of the Dog came in. They understand and have put the training place. Remember the saying: 3 days to decompress, 3 weeks to learn your routine, 3 months to show their personality. These fights were the decompression window. With time to learn ‘I’m safe. They won’t hurt me. I can trust the humans. I can trust the dogs’ we’re seeing the Cassie that shows how much love and work were poured into her. If you’re looking for a puppy work-in-progress, you will enjoy the loveliest walks, a potty trained, bell trained & doggie door trained dog, who is learning trust, a dog that enjoys car rides and treats galore, Cassie is the girl for you! www.coloradopuppy.org/how-to-adopt

Story
Adoption Fee: $475 When available, all animals are fixed in accordance with Colorado law, up to date on vaccines (may need boosters), and microchipped! What we know: Litter of 6 transferred from Animal Services Center of the Mesilla Valley in NM. Found on the side of road when finder was on his way to work, he drove the road looking for mom but could not find her and brought the puppies to the shelter to receive proper care. From the foster: Funyun has the softest fur, the sweetest little soul and a belly that is almost always available for rubs! She loves playing with her siblings, getting head scratches and following her favorite people from place to place. Funyun can be shy and a little nervous when something—or someone—is new, and knowing her story makes earning her trust feel even more special. She and her siblings were found on the side of a road in New Mexico at only about five weeks old, without their mama. After such an uncertain beginning, she sometimes needs a moment to make sure everything is okay. Once she realizes you’re there to keep her safe, though, she blossoms into the most loving little companion. Funyun has done beautifully with kids ages 7–14 and has been fostered with two older, larger dogs. She’s still learning potty training and will go right away when taken outside, but she does still have accidents in the house while she figures everything out. Watching this sweet girl learn that she will be fed, cared for and loved every single day has been incredibly special. Now Funyun is ready to find the family who will keep that promise for the rest of her life. 💚 www.coloradopuppy.org/how-to-adopt
