Story

🐾 Meet Sully! Those eyes! 😍 Sully is a 6-month-old, Dane/Lab mix, sweetheart with one gorgeous blue eye, one warm brown eye, and a personality that’s just as adorable as his looks! This goofy, silly boy is a professional lap dog in training who loves cuddles just as much as playtime. He enjoys playing with his canine siblings, loves children, and walks nicely on a leash. Sully is also eager to learn and ready to keep growing into the amazing dog he’s meant to be. Of course, he’s still a puppy, so he’s learning his manners and figuring out this big world one day at a time. Sully will thrive with a family committed to daily exercise, continued obedience training, and positive reinforcement to help him become the best boy he can be. He’ll need regular opportunities to burn off that puppy energy, work his brain, and keep learning! If you’re looking for a sweet, fun-loving companion who will make you laugh, fill your days with puppy kisses, and happily snuggle up in your lap (even when he gets too big for it!), Sully might just be your perfect match! 🐶 All this handsome boy needs now is a family to love him, guide him, and help him thrive. Sully is being fostered in Castle Rock, Colorado. *We require all adopters to come to Colorado to adopt. *We do not transport dogs.* You can view this wonderful dog at https://www.milehighcanine.org/post/dogs/sully/.

For more information about this Dane, please visit our website at https://rmgreatdane.org. Adoption Applications link can be found on the home page. Meet Chevy Status: Available Sex: Spayed Female – Gastropexied Color: Merle Ears: Natural Age: 6 yrs Weight: 108 lbs Great Dane Experience Required Adoption Fee – has been paid by a generous sponsor Chevy is a beautiful 6-year-old merle Great Dane looking for a special home that understands her needs and is ready to help her continue building confidence. At her core, Chevy is an incredibly loyal Dane who forms deep bonds with her people. Once she trusts you, she'll happily follow you from room to room, curl up nearby while you relax, and remind you why Great Danes are known for their devotion. She loves playing fetch with her Kong stick, zooming around the yard, and soaking up time with her favorite humans. Chevy is house-trained, crate-trained, knows basic commands including sit, down, come, stay, and off, and responds well to hand signals. She enjoys learning, especially when rewarded with her favorite all-natural treats. While Chevy has many wonderful qualities, she is looking for a very specific home where she can thrive. Chevy can be reactive to people and animals she sees through windows, on walks, or while riding in the car. She will bark and lunge when triggered and will need continued training, patience, and consistent leadership to help her work through these behaviors. Because of her reactivity, Chevy must be the only pet in the home. She is not a candidate for homes with other dogs, cats, or small animals. She also requires an adult-only home with no children. Chevy's ideal adopter will have previous giant breed experience, understand canine body language, and be committed to continuing her training and confidence-building. She would do best in a calm, predictable environment with a securely fenced yard where she can safely run and play. In return, Chevy offers unwavering loyalty, affection, and companionship. She settles in quickly with her people, enjoys spending time with her family, and loves nothing more than being close to the person she trusts. If you're an experienced giant breed owner looking for a devoted companion and are willing to provide the structure and training Chevy needs, she may be the perfect addition to your family. More about Chevy: Great Dane Experience Required Housetrained:Yes Crate trained: Yes Needs a calm home - dog savvy adults and teens only No dogs No cats Reactive to new people and dogs Professional training in process and will need to be continued Fearful and anxious around new people - needs slow introductions October 26, 2026, 12:20 am

Story

Dane was running out of time through no fault of his own. He found himself in a small rural shelter where space had run out, putting him on the euthanasia list simply because there wasn't room. Thankfully, Dane got a second chance. At around a year old, this stunning blue merle Great Dane mix is as easygoing as they come. He enjoys going for walks, hanging out with his dog friends, and taking plenty of naps in between. Dane gets along great with dogs of all sizes and with cats, making him an easy fit for many homes. He is a calm, laid-back guy who is simply happy to be included. Good fit: someone looking for a relaxed companion who enjoys walks, naps, and spending time with both people and other animals. Adoption process: All adoptions are completed prior to transport. Dogs are picked up at designated transport locations. If an adoption doesn’t work out (rare, but life happens), we always take our dogs back. Location: Oklahoma (available to approved out-of-state adopters via transport) Health: Fully vetted (neutered, vaccinated, microchipped, heartworm tested) Adoption fee: $450 (includes transport + vetting) Bonus: Each adoption includes a 30-minute phone consultation with a professional trainer Transport routes: WA, OR, ID, MT, UT, WY, CO, MN, WI, IA, IL, IN, OH, PA, MD, NY, NJ Think you might be a good fit?

Story

`Mater` is a wiggly, friendly youngster with loads of energy. Mater will do best in an active home with experienced owners who will provide consistent, positive reinforcement training as he learns to channel his `vroom vroom` and know when to keep that engine idling! He is so much fun and will be a great addition to any family. We don't know much about his history so we recommend you bring in other dogs and children who live in the home, to make sure it's a good fit for this silly goofball.October 29, 2026, 6:54 pm

Sierra

Anatolian Shepherd Great Pyrenees

Female, Young

BOULDER, CO

Size

(when grown) Large 61-100 lbs (28-45 kg)

Details

Good with kids, Not good with cats, Needs experienced adopter, House-trained, Spayed or Neutered, Shots are up-to-date,

Story

Sierra is a five-year-old ~110-pound Anatolian shepherd mix who came from a family in Montana that was unable to give her the care and attention she needs. She was kept outside too much, but we have been working with her since February, integrating her into our family, dog walks, belly rubs and brushing, etc. She's a working/herding/guard dog but is also a goofball and a very cuddly teddy bear who loves people and has done well around children. She does have protective/guarding tendencies that seem to have been exacerbated by her situation at her former home, and would do best in a house with a fenced yard and without other dogs or pets (strong crittering instinct). However, she has also made HUGE progress on her dog walks and hasn’t shown any reactivity to other dogs in weeks. Sierra loves being brushed, hanging out with her people, and belly rubs. She is a very sweet girl and would make a great companion for the right person!

Story

MEET SIERRA! Sierra is a 5-year-old, approx. 90-pound Bernese/Anatolian mix girl who came from a family in Montana who were unable to give her the care and attention she needs. She was kept outside too much, but her rescuers have been working with her, integrating her into their foster family with dog walks, belly rubs, brushing sessions and lots of love. Sierra is a working/herding/guard dog but is also a very cuddly teddy bear who loves people and has done well around children. She does have protective/guarding tendencies that seem to have been exacerbated by her situation at her former home. We think she'd do best in a house with a fenced yard, and without other dogs or pets. However, she has also made HUGE progress on her dog walks and will benefit from ongoing training. Sierra loves being brushed, hanging out with her people and getting lots of belly rubs. She is a very sweet girl and would make a great companion for the right person! For more info and/or to apply to adopt Sierra, send us an email at SummitDogRescue@gmail.com, telling us a bit about yourself, your home environment and your lifestyle. A volunteer will get back to you shortly.
