Story
Just arrived in Colorado after a long wait to be rescued! Arrived at shelter with her son who is in a foster home in Texas - was clear they weren’t well taken care of and were used for breeding. Recently had a litter and owners kept the puppies She is 109 pounds but still underweight and will need someone that is able to handle a dog that doesn’t always understand its size. She is a very sweet girl that will be easy to train! She is doing really well with another larger dog in the home- she loves to cuddle and go on walks with him. Greets all new people with affection and love. Great in the car and even when getting a bath. Follows her foster Mom around everywhere and gives little kisses when she can. She is getting her cherry eyes fixed, spayed and bloat fix surgery all on 6/2; after some recovery time will be available for adoption Please note she is Heartworm positive (non contagious and treatment is required as part of adoption- paid for by us going to our vet in Golden)

Story
Meet Buddy Bear.  This handsome boy is looking for his furever home. Buddy Bear is a 65-pound 2-year (est bd 2/15/2023) Catahoula Leopard/Great Dane mix. He’s a love bug who would like nothing better than to lean on you while enjoying his day. Buddy has a very chill demeanor – watching the yard from the deck, lounging in his crate, but his teenage energy kicks in when he plays and gets excited. He picks up new tricks very quickly, is highly motivated by treats, and loves his routines. He’s learned to sit, stay, lie down, and shake, and is currently working on his leash manners. He would do well in a home that can keep him active and one with a 6-foot fenced-in yard. He LOVES to run! He wants nothing other than to be part of a loving family and love them back! Put in an app at EAPL.com and make this guy your new best friend!   His Summertime Sponsor adoption fee is $75 Put in an application at eapl.comMay 28, 2025, 9:15 am

Merle has spent some time settling into his foster home, and now he’s ready to find his forever family!

Great Dane

Female, Adult
Lakewood, CO
Size
(when grown) X-Large 101 lbs (46 kg) or more

Story
For more information about this Dane, please visit our website at https://rmgreatdane.org. Adoption Applications link can be found on the home page. Chevy has officially settled into her foster home, and now this one-of-a-kind Great Dane is ready to find her forever family! She’s five years old, merle-colored, and packed with more personality than her giant paws can hold. Let’s get one thing straight—Chevy is a total sweetheart . She’s affectionate, playful, and talkative (with the cutest little grumbles). If you’re looking for a Velcro dog who leans in hard for love, insists on couch snuggles, and lives for grass zoomies, this girl might just be your soul-dog. But—real talk—Chevy is also a work in progress. Personality Snapshot Chevy is: A snuggly couch potato A toy-destroying queen A leaner and lap dog (yes, all 100+ pounds of her) A full-on clown when she’s in a playful mood &#239&#184&#143 Talkative, mouthy, and all about the kisses Obsessed with grass rolls (seriously, it’s her zen zone) Extremely fearful of strangers, new sounds, sudden movements… and apparently grills. Once she trusts you, though? She’s all in. Expect face nibbles, dramatic flops, and lots of paw swats for attention. She’s got more enthusiasm for life than most people at a theme park. Training & Habits Chevy knows several commands including: &#226&#156&#148&#239&#184&#143 Sit &#226&#156&#148&#239&#184&#143 Down &#226&#156&#148&#239&#184&#143 Stay &#226&#156&#148&#239&#184&#143 Come &#226&#156&#148&#239&#184&#143 Off Plus, she responds to hand signals like a champ. She’s crate trained, house-trained (mostly—occasional accidents happen), and totally food motivated. She waits patiently at mealtime, even if you’re cruel and make her sit for 10 whole minutes. (You monster. LOL) Chevy walks okay on a nose-loop leash but does pull if she sees something “suspicious” (read: a stroller, a trash bin, or the aforementioned grill). She’s currently working on desensitization and doing her best! And yes—she counter surfs and has been known to shred a blanket or two when anxious. But hey, no one’s perfect. Fears & Challenges Chevy is working through her fears and needs someone committed to training and confidence building. She reacts to: ‍&#226&#153&#130&#239&#184&#143 Strangers (especially men) Kids (less scary than men, but still suspicious) Dogs (aggressive barking from afar) Loud or sudden noises Fireworks, vacuums, and other chaos She barks, growls, and can act out, out of fear. Her tail is often tucked, and her body language screams “please don’t hurt me” more than “go away.” With slow intros and positive reinforcement, she’s made steps forward—but she’ll need a family who truly gets it. What Chevy Needs Chevy isn’t a plug-and-play pup. She’s looking for: A calm, structured home Patient, experienced dog people Dog Savvy Adults or teens only (no young kids) A fenced yard for zoomies and grass therapy A routine—seriously, she thrives on schedule People who will laugh when she sits like a cat She’s not currently dog or cat-tested in close quarters, but based on her reactivity, she’ll do best as the only pet in the home. &#226&#157&#164&#239&#184&#143 Why She’s Worth It Chevy might never be the dog you take to a busy café or the farmers market. But she will be the dog who makes you laugh every single day. Who cuddles hard. Who teaches you patience, trust, and the magic of tiny victories. She is goofy. She is loving. She is flawed. And she is so ready for a home that sees her heart and wants to help it heal. More about Chevy: House-trained: Yes – still has occasional accidents.  Crate trained: Yes Needs a calm home – dog savvy adults and teens only No dogs – has shown reactivity from a distance No cats – high prey drive Will counter surf and steal food – needs supervision  Basic Obedience Training complete – knows sit, stay, come, down, off Fearful and anxious around new people – needs slow introductions Pulls when excited on leash – needs additional training May 12, 2025, 9:41 am

Dog Friendly — She’s met two dogs in her foster home and enjoyed playful interactions without any jealousy or aggression.
