Story
Princess Tomboy here, are you curious about my unusual name? I totally understand, I’m curious about most things…let me tell you a little about myself! If I were a human, my sport would be rugby, I’m a rough and tumble girl with an active play style therefore I need another playful pup in my life (if you don’t have another dog and would consider adopting 2 check out Tuuli, she’s a real sweetheart, and we get along great in our Denver foster home; she even lets me take her toys). A fenced yard is high on my wish list as I love doing zoomies and chasing bunnies, birds, squirrels, etc. A fence helps keep me safe. I enjoy my walks and I’m learning my commands. One thing my foster mom was particularly proud of was when I picked up a chicken bone in the park, she told me to drop it, I did; this has happened twice now. Do you know how hard that is, they’re yummy. I have solid recall and walk well on leash, I’m making good progress stopping and waiting at corners and learning to sit. I love water and I’m sure hiking is something I would enjoy. I am young and need a home committed to continuing my training. I do have a snuggly side and love to curl up with my people and will sleep through the night. My wiggle butt involves my entire body when I see you. I’m such a happy girl! I know this is a lot, but I guess that’s the princess part of my name. I figure I have one shot at this forever home thing and I want to make sure it works for both of us. If I seem to be a good fit for you why wait please fill out the application and add a little joy to your life! Thanks for taking the time to read my profile love Princess Tomboy. 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 spayed, microchipped and up to date on vaccinations ##2732831##

Luna is 4 years old. She was a Rescue puppy. Luna is a very sweet yet neurotic border collie. She loves to play fetch and unique sounds get her excited. She is an excellent listener but you have to know her potty routines and she will be great! My life circumstances don’t allow me to give her the time that she deserves. Looking for a loving home that she can get the attention she deserves. Luna has an older sister dog, Maizey, a heeler mix, that I’d like to have them adopted together, if possible.

Story
Hi!! My name is Dumpling and I seriously cant wait to meet you! I am an incredibly social and friendly little fluff ball. I am a take everywhere kind of girl - breweries, parks, walks, I want to be where the people are! My other favorite thing to do is play with other dogs - I am fearless and play pretty rough - but with the right dogs, we have a really good time! Im really smart and learn really quickly so will be really fun to train. I'm looking for a pretty active home that will take me lots of places and do lots of activities with me. Having another really playful and easy going dog would be great, but if not, I would be happy with multiple weekly playdates. I'm still a baby, so continued training and socialization are important, but I will be the best companion for someone!  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 spayed, microchipped and up to date on vaccinations ##2711025##

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. 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 (spayed, 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, VT Think you might be a good fit?

Story
Meet Ogallala, but everyone calls her Olga! This sweet, beautiful girl is a Border Collie Australian Shepherd mix with a gentle and silly heart that will make you smile. When she came to Soul Dog in 2021, she was shy and fearful, but thanks to her long term foster family, she has made amazing progress.Olga has gone from hiding in her favorite corner to relaxing on the sofa with her foster pack, greeting her family at the door, and even asking for affection. One of her favorite pastimes now is shouting out the window at people and dogs passing by. She really loves letting her voice be heard!While she has gained confidence, Olga still has a few fears. Loud noises, sudden banging, or busy sounds like kids playing basketball can startle her. When she is unsure, she may bolt and then settle in a safe spot. With gentle guidance and patience, she is learning that the world can be safe and fun.Olga is looking for a kind, understanding person who can give her love, calm guidance, and the time she needs to feel confident in a new home. Because she is so comfortable in her foster home, a gradual transition to her forever family will help her adjust and thrive.Olga is a sweet, joyful girl who is ready to bring love, smiles, and laughter to her forever home. If you would like to meet her, submit an application at www.souldog.org. For questions, email adopt@souldog.org.

Alder

Border Collie

Male, Young
Ft Lupton, CO
Size
(when grown) Med. 26-60 lbs (12-27 kg)
Details
Good with kids, Good with dogs, Good with cats, Spayed or Neutered, Shots are up-to-date,
Story
Alder is basically the dog version of an introvert. Quiet, gentle, low-key, and completely content doing his own thing, Alder is one of the easiest and lowest-maintenance dogs I have ever had in the rescue out of hundreds of dogs. He is around a year old and was originally labeled as a pit bull mix at the shelter when he was younger and still looked like a generic puppy. But now that he is older, it is very obvious that he is not a pittie and instead looks much more like a Border Collie mix. Alder is wonderful with other dogs of all sizes and also great with cats. He peacefully coexists with everyone but honestly doesn’t care much about joining the chaos or playing constantly. He prefers to quietly exist nearby and observe the world at his own pace. He is shy and hesitant with new people at first, but there is not an ounce of aggression in him. He is simply a soft, sensitive dog who takes a little time to feel comfortable. Once he settles in, Alder is incredibly easy to live with. He is not demanding, not hyper, not loud, and not needy. He is the type of dog who quietly becomes part of your daily life without bringing chaos into it. Good fit: someone looking for a calm, quiet, low-maintenance companion who does not need constant stimulation or activity to be happy. 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/spayed, 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, VT Think you might be a good fit?

Good with kids, Good with dogs, Not good with cats, Needs experienced adopter, House-trained, Spayed or Neutered, Shots are up-to-date,
Story
Oliver is a beautiful 6 year old black and white Border Collie/Australian Shepherd mix with an intelligent and sensitive personality. He thrives in open spaces and would do best in a calm, loving home with lots of land or room to roam and explore with other dogs. He’s happiest when he can be outside, stay active, and bond closely with his people. Oliver is incredibly smart, observant, and affectionate once he feels comfortable. Like many herding breeds, he does best with consistency, structure, and someone who understands active working dogs. He would be an amazing fit for a home in the country or with someone experienced with Border Collies or Australian Shepherds. Ideally Ollie’s new home will provide plenty of space, patience, companionship, and the stable environment he deserves.

Story
Lux was born July 2017. I adopted him when he was 4 months old. He's good with kids and new people. He's such a lover and loves butt scratch's. He's house trained loves to go on car rides and does well at the dogs parks too. His one downfall is the guy loves the trash. For whatever reason anytime he gets his chance he will rummage through the trash. 🤦🏻‍♀️ Unfortunately I've had a schedule change and I am not home as often as I need to be therefore he has been acting up for attention and it's just not fair to him. He has a brother and a sisters he's more bonded to his sister, but I think would do fine if separated.

Good with kids, Good with dogs, House-trained, Spayed or Neutered,
Story
Howie is 3 years old he is house trained. He does okay with other dogs if properly introduced. He has two other dogs he's lived with his entire life. Him and my other male dog have got into food altercations. But as long as he is feed separate no issues have been present. He's good with kids, tends to need extra time to warm up to males as he's only been a female.. because of the cattle dog in him when he gets excited or needs attention he nips at butts, never has harmed anyone while doing it. He loves to be outside and run often times will fight me to come inside. Rehoming due to my a new schedule change. I'm not home as often and it's not fair to my dogs to be home alone as much as they have been.

Star is about 10 years old. She is GREAT with kids, gets along with other dogs, is loving and is not aggressive at all. She is getting older and will need more personal attention than we can offer. We are in and out of the house with younger kids and their activities and feel she can benefit from a family that can give her more.
