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: Two 2-month-old sisters transferred from Operation Kindness in Texas as owner surrenders. From the foster: Meet Willow — a fearless little girl who will brighten even your darkest days. At just eight weeks old, Willow is the perfect balance of playful energy and gentle calm. She loves exploring the world around her, testing her boundaries, and discovering new things with curiosity and confidence. Willow is already making great progress with her early training. While she’s still learning the basics, she is eager to please and responds well to guidance and consistency. She is kennel trained and settles nicely—especially when she’s ready for rest. If she has a little extra energy, it may take her a few minutes, but she’s learning quickly how to relax. She is currently working on potty training. Willow is doing well going outside and is continuing to learn how to communicate when she needs to go. With a consistent routine, she will continue to build on this success. Like any young puppy, Willow is in her teething phase, so chew toys are her favorite companions. She’s learning what’s appropriate to chew and is already showing great progress. Tennis balls are another favorite—while she hasn’t quite mastered fetch yet, she loves carrying them around and making them part of her playtime. Willow truly offers the best of both worlds. She’ll happily follow you on little adventures, play and explore with enthusiasm, and then curl up beside you for a peaceful nap. She is the more confident and adventurous one between her and her sister, with a personality that shines a little brighter each day. If you’re looking for a puppy who will fill your home with joy, companionship, and warmth, Willow may be the perfect fit. www.coloradopuppy.org/how-to-adopt

What we know: Two 2-month-old sisters transferred from Operation Kindness as owner surrenders. From the foster: Meet Wren — the perfect balance of cuddly and adventurous, and the puppy you didn’t know you needed. At just eight weeks old, Wren is already showing a beautiful mix of curiosity and calm. She may be the bigger of the two sisters, but she’s also the more gentle and reserved one. While she enjoys exploring her surroundings and learning what it means to be a puppy, she is also wonderfully respectful of boundaries and eager to do the right thing. Wren is making great progress with her early training. She is eager to please and responds well to consistency, even as she continues to learn the basics. She is kennel trained and settles nicely—especially when she’s tired. If she has a bit more energy, it may take her a few minutes, but she is learning how to relax and feel comfortable. She is currently working on potty training. Wren is doing well going outside and is continuing to learn how to communicate when she needs to go. With patience and routine, she will continue to improve. Like any young puppy, Wren is in her teething phase, so chew toys are her favorite. She’s quickly learning what’s appropriate to chew and is already making great progress. She also loves tennis balls—while she hasn’t quite mastered fetch yet, she enjoys carrying them around and making them part of her playtime. Wren has even started exploring the doggy door, occasionally letting herself outside. She’s still figuring out how to come back in, often waiting patiently by the door for a little help—another reminder that she’s learning more every day. Wren truly offers the best of both worlds. She’ll happily follow you around, join in on playtime and exploration, then curl up beside you for a cozy nap. She also has an independent side and is perfectly content relaxing on her own nearby. If you’re looking for a loyal, loving companion who will grow with you and bring a calm, steady joy into your home, Wren may be the perfect match. www.coloradopuppy.org/how-to-adopt
