Poppy is a gentle soul with a very shy and timid temperament, but once she feels safe, her playful side starts to shine. Poppy will thrive in a home with a fenced yard and plenty of room to play. Having her own secure space helps her build confidence and gives her the freedom to explore without feeling overwhelmed. She’s a tender, sensitive girl who just needs the right environment to blossom — and she’ll reward her family with soft affection, sweet moments, and a loyal heart.

Story
Hi there, my name is Dora and I’m curious are you my forever home? My foster mom says I should start out with some of those facts that people want to know to see if we’re a good match. I’m a happy girl who gets along well with dogs and people. I’m crate trained, housebroken and doing well learning commands. I’m that perfect knee height so easy to reach down and pet me. Most likely I won’t get much bigger…35 to 40 pounds as an adult and I don’t shed a lot. OK now the fun stuff… I play well with dogs…different play styles…chase, wrestle, tug-of-war…I’m up for all of it but I’m not too pushy. I share my toys and I also self entertain. I enjoy my walks, pay attention to my human and appropriately meet other dogs and people. I like playing with my humans, fetch is fun! I am a young active girl who would do best in a home with a yard and another playful companion in my life. I am good at staying with my human but not overly clingy. Learning new things makes me happy. Are you willing to continue my training? I promise to be a really good girl and put a smile on your face every day. If if you think I might be the one for you, please fill out the application now and we can meet. Thank you for taking the time to read about me. Love Dora. If you're interested in meeting me please fill out an application at www.thegooddogrescue.org (If you already have an approved application, please email thegooddogrescueadoptions@gmail.com with your interest in me!) My adoption fee is $350 and I am spayed, microchipped and up to date on vaccinations for my age ##2848579##

Story
Hey it's me Mochi. I'm also known as Mochi man because I'm the real MVP. I am calm, cool and collective most of the time. You can find me as your shadow, or simply snoozing in my free time. Toys are fun, but are short entertainment for me. I feel like I'm learning quickly with commands, and love a good treat for motivation. I sure do enjoy my daily walks, and am super confident while walking on my leash. Did you say you like to adventure? Count me in. I cannot wait to meet you soon. I'm looking for a home with another social playful dog, and a family that will take me lots of places!  If you're interested in meeting me please fill out an application at www.thegooddogrescue.org (If you already have an approved application, please email thegooddogrescueadoptions@gmail.com with your interest in me!) My adoption fee is $400 and I am neutered, microchipped and up to date on vaccinations and preventatives ##2845690##

Story
Wanda is the perfect combo - the legs of a giraffe, ears of a fox, and fur highlights any hairdresser would be proud of. She is a sweet, sweet soul who is still learning to trust and settle in.  She is a little uncertain of other people and dogs on walks but LOVES praise and looks to you for guidance. While she is really good at hanging while we work, or being lazy when we are, we know she's got some energy in there! We think she'd do great in an active home - whether that be going on runs, or hikes, or maybe even a medal winning agility dog if she aims high. We think she would thrive in a house with another dog sibling to show her the ropes. She becomes so playful once she has warmed up to another dog, and becomes much more confident with a buddy by her side. She immediately loved the visitors we've had to our house and we get full body wiggles and whines of excitement when we leave the room even just for a second and come back. She's a lover! Wanda is getting braver and more confident each day, and her puppy continues to come out! She could spend all day outside, watching the squirrels and birds, sniffing flowers and rolling in the grass. Potty training is a work in progress but we have already seen improvements. She has been sleeping in her crate at night and whining in the morning when she needs to get out. We have yet to see her use the bathroom on a leash however - she's stubbornly good at holding it and likes her privacy, so she consistently goes to a certain spot in our yard. She's very food motivated and responsive to any redirecting her away from things, especially for a puppy who is curious about everything! Don't you Wanda bring her home?! ##2841948##

Story
Huey is a 4 year old pit/border collie mix (we think?). He is a great dog, but he does not get along with our 2 year old son and has shown anxiety around him. He is an active boy, loves to run and play as much as possible. He is also a snuggle bug. Loves rubs and attention and will follow you anywhere. He is kennel and house trained and up to date with vaccines. He would do well in a home without young children or cats as he tried to herd our cats and needed to be kept separate. Older teens are fine.

Story
Mac came to rescue as a puppy last summer with his three siblings, Dee, Dennis, and Charlie. All three of them were adopted promptly, but somehow Mac is still waiting for his turn. His siblings looked more like German Shepherd mixes, but Mac took a different direction. At just 36 lbs, he looks more like a Border Collie/Heeler mix and is a great medium size. Mac is a happy, easygoing boy who is very low maintenance and doesn't need constant attention or entertainment. He's great with other dogs and with cats and is perfectly content just being part of everyday life. After watching all three of his siblings leave for homes of their own, it's time for Mac to finally get his. Good fit: someone looking for a happy, easygoing, low-maintenance companion who gets along well with both dogs and cats. 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), I always take my dogs back. Location: Oklahoma (available to approved out-of-state adopters via transport) Health: Fully vetted (neutered, vaccinated, microchipped, heartworm tested) Adoption fee: $500 (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
Jazzy is the kind of dog who brings energy and happiness into your life—without overwhelming it. She’s playful, friendly, and fun, but also has an independent side that makes her easy to live with. Her past isn’t pretty—but you’d never know it. Jazzy is social and confident, great with dogs of all sizes and cats, and naturally fits into whatever environment she’s in. She’ll happily join in on playtime, go on walks, or even randomly take a dip in the pond—then settle down like it’s no big deal. She’s affectionate without being clingy and has that ideal balance people are always looking for but rarely find. Good fit: someone who wants a fun, social dog that adds energy and joy to daily life without being overwhelming or demanding. Adoption process: All adoptions are completed prior to transport.

Gavin has a tiny blue speck in one of his eyes that makes an already handsome face even more unique. At around 2 years old and 37 lbs, he may be a Heeler/Border Collie mix and is a great medium size. Gavin is a friendly, mellow guy who gets along great with other dogs. Despite the breeds he resembles, he isn't a high-strung, constantly-on-the-go dog. He's easygoing and happy just hanging out with his people and dog friends. He's a sweet, uncomplicated boy with a calm personality who would fit easily into a lot of different lifestyles. Good fit: someone looking for a friendly, mellow, medium-sized companion who gets along well with other dogs and doesn't need constant activity to be happy.

Story
Meet Doc ❤️ We adopted Doc at 7 months old from a farm where he and his littermates were badly abused. Because of his past, he is very skittish and absolutely terrified of men. He needs a patient, understanding home willing to earn his trust. Doc is a funny, active little guy who loves toys, treats, and will even do a couple tricks for an ice cube! He does amazing with other dogs, children (boys and girls), and women he doesn't know. He is potty trained, kennel trained, and dog-door trained. He loves a good movie night so he can get cozy and cuddle. His biggest challenge is his fear of being harnessed and leashed. Unfortunately, our new home doesn't have a fenced yard, making walks necessary. Getting his leash on can be difficult because he is so scared. Once it's on, though, he is ready to go—and LOVES his walks, or should we say runs! We are looking for a loving, patient home that will give Doc the time and confidence he deserves. He has so much personality once he feels safe.

Story
Hi I'm Griffin, but my friends call me Yodi!  I'm a little over a year old and about 50 pounds. I love people and other dogs, but no kitties please!  For a young guy, I have quite a story! My foster mama was down in new mexico volunteering at a spay neuter clinic and was staying in a cabin in a fairly remote area. I had been loose for a while and was really hungry and she looked pretty nice, so even though I was really scared, I made a few appearances on her porch hoping she would see me. She did, and spent a few hours luring me in with food and snacks. The vet team was able to check me out and get me all my pokes and prods so I could travel home with them to Colorado. Even though I was frozen with fear, I was a really good boy and let them do what they needed to.  After a few months in my foster home getting fattened up, I learned that I actually really love people and get really excited to meet new ones! Some dogs I need a little slower intro with, but some I love right away and am ready to play! I would do best in a home with another social and playful dog, no kitties please. I do need a 6ft tall fence though, I'm part kangaroo I think (they have those in NM right?). Besides hanging out with my people and dog friends, I also like to "herd" all my stuffies into one big pile.  TLDR: I am looking for a house with a yard and a tall fence, a doggie companion, no kitties, fairly active humans, and lots of fun and love!  If you're interested in meeting me please fill out an application at www.thegooddogrescue.org (If you already have an approved application, please email thegooddogrescueadoptions@gmail.com with your interest in me!) My adoption fee is $300 and I am neutered, microchipped and up to date on vaccinations  ##2778427##
