Meet Patunia! ******Please note, once completing the initial screen you will be connected with the placement for a video chat. Transports run every few weeks and we will have the dog on the next available transport once approved. If you are not able to accept a dog until a specific time period, please apply at that time************ We are a volunteer run rescue and donate our time to these dogs. IF you area not serious about moving forward in our adoption process, please do not apply. If someone other than yourself is part of the decision making process, please make sure you have spoken with them and they are on board. We really do not want to waste anyone's time if you are not serious about adopting this dog. Patunia is an spayed, 2.5 year old female Border Collie mix, currently weighing around 68lbs. She is in a foster home in Houston, TX, and can transport out of state once an approved adopter is found. This big sweetie is the ultimate girl’s girl! She’ll be your biggest cheerleader for the wins and the losses, and will always agree that your girl math is 100% correct, especially if it involves some goodies for her too. Patunia is very affectionate and LOVES to snuggle and get kisses from her people! You’ll always find her near by and she is a huge fan of sleeping in your bed. Patunia is very gentle towards children, and enjoys having them as a cuddle/play mate. She is fearful of men, but adores women and children. She can be independent, but prefers her humans close by. Once Patunia forms an attachment to you, she’ll hug your legs and won’t let go. She is very playful and obsessed with all of the toys! She shares well with the resident dogs and humans too. She does prefer to dine solo however, so feeding away from others is recommended. Patunia is high energy, favoring dogs that can keep up with her. She is very friendly towards other dogs, and is excellent on picking up on their cues, especially when a dog isn’t interested in playing. Patunia is cat friendly with slow introductions. She is very curious about the resident kitties, and will follow them around. She may chase them to get them to play, so supervision is recommended. This good girl is very well trained on a leash, walking gently and calmly, and she is house and crate trained. She is only crated when unsupervised or left home alone for her own safety, as she can chew on random items. She has a little separation anxiety, but having another pup around helps her feel safe. Patunia will thrive in a home with a family or a single woman looking for a best friend! She just needs to have a close bond of friendship and love. She would also benefit from having another dog in the house that will play endlessly and help her feel safe. She would love a spacious back yard to help burn off her energy. We can’t wait for Patunia to find someone who will spoil her endlessly, because she deserves that and more! ***Listed BREED and AGE - We are taking our best guess & recommendations from our veterinarian on age, breed and size when fully grown. We rarely know a dog's exact age nor are we able to tell the true or full breed mix of dogs as our information is limited most of the time. *** Interested in applying to adopt her?

Our little beautiful Roxy is something else! She is so intelligent and happy, and wants to be with a family. She adores children, and the seven year old in the house has taught her to fetch and lots of other things. She is gentle and precious, only about 30 pounds at a year, so is smaller, and loves getting attention. She is crate trained and house trained, enjoys other dogs, loves being outside, and walks well on a leash. She is ready for her forever best friend. She enjoys water, tummy rubs, and showing off how smart she can be. She is a bit frightened of cars rushing by and can be a little shy when she first meets you, but when she comes in for scratches, it is such an amazing feeling. Roxy enjoys everything about having a family, and cannot wait to find her forever!

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.

Story
Alder is an extremely sweet, quiet, shy boy. He is the dog version of an introvert. He is gentle and sticks to himself and is great with other dogs of all sizes and with cats. He doesn't engage much with them thought as he prefers to do his own thing. He has to be the most low maintenance and chill dog I've ever had in the rescue out of hundreds of dogs. He is hesitant with people he doesn't know but never aggressive. Not an ounce of aggression. He was listed as a pit bull mix at the shelter when he was smaller and still a younger puppy but now that he is an older puppy (about a year) it's obvious that he is not a pittie but looks more like a border collie. He is currently still in Oklahoma where he was rescued but he can only be adopted out of state where people treat animals well. He has to be prepaid and picked up directly from transport at one of our transport drop off locations below. If things don't work out for some reason, which rarely ever happens, we will either find a local foster to take him in or he will go back to Oklahoma on our next transport until a new home is found. Note: No dogs are advertised as potty-trained because most dogs need at least some re-training in a new environment and after being in a shelter/rescue environment/strays. www.facebook.com/desideratarescue/reviews (copy and paste into a new browser window) Transport locations: - Washington State (Kennewick, Spokane, Tumwater, Tacoma, Tukwila, Lynnwood/Edmonds, Bellingham) - Oregon (Portland and Springfield) - Colorado (Ft Lupton) - Idaho (Heyburn and Boise/Meridian) - Utah (Ogden) - Wyoming (Evanston, Rock Springs, Laramie) - Montana (Missoula) - Illinois (Vandalia, Springfield, Chicago) - Indiana (Spiceland, Burn Harbor) - Michigan (St Joseph, Battle Creek, Ann Arbor) - Wisconsin (Madison, Wausau, Eau Claire, Appleton, Milwaukee) - Minnesota (Minneapolis/St Paul) - Iowa (Des Moines) - Ohio (Columbus and London) - Pennsylvania (Erie, Pittsburgh and Harrisburg) - New York (Buffalo and Albany) - Connecticut (Enfield) - New Jersey (Bedminster) - Nevada (Las Vegas) - Arizona (Flagstaff) Vetting: neutered, microchipped, rabies vaccine, bordetella vaccine, dhpp vaccine x 3, lepto vaccine x 2, dewormed several times, on monthly flea and tick prevention, on monthly heartworm protection, heartworm tested (negative) Adoption fee: $550 (includes the $250 cost of transport from Oklahoma and all vetting listed above) Adoption application (copy and paste into a new browser window): https://form.jotform.com/82677586784176 FAQs (copy and paste into a new browser window): https://docs.google.com/document/d/12eb_SRtk1AzaBl87UltcLJ24MjH9UhQm_LE77iWZEQA/edit?tab=t.0 Desiderata Rescue is Oklahoma Licensed Rescue #95

We really do not want to waste anyone's time if you are not serious about adopting this dog. ___ Meet Mylo – a 4-year-old, neutered, 44-pound Cattle Dog mix with a tongue that just can’t be tamed and a heart that’s even bigger. Currently in a foster home in San Antonio, TEXAS, Mylo is ready to transport out of state once his forever family is approved and ready to fall in love. Let’s start with the obvious: Mylo has a perma-blep. That’s right—his tongue is just a little too long for his mouth, and it’s almost always peeking out like he’s mid-lick or permanently saying, “hi.” A vet has checked it out and confirmed there’s nothing wrong—he was just born with extra tongue and endless flavor to sample. It doesn’t cause him pain, but it does mean he occasionally needs a little extra hydration. He also has a slight protruding bone at the base of his rib cage—again, no cause for concern, just more proof that this boy was truly “born this way.” We like to say he’s one part goofball, one part model, and 100% original. Mylo is an affectionate, silly, and curious guy who loves to play and explore. He has a bit of that classic Cattle Dog energy—he thrives with daily activity, enjoys long walks, and loves a good romp in the yard. He plays well with dogs of all sizes and currently lives in a multi-dog home with pups ranging from tiny Chihuahuas to an 80-pound Boxer mix. He does well reading other dogs’ social cues and adjusts his play accordingly. He’s also very vocal when he plays or gets excited—growling, grunting, and making silly noises are just part of his charm. Once you get to know him, you’ll realize it’s just his voice, not a sign of anything aggressive. He enjoys meeting new dogs on walks, though he might sound a little intense at first—again, that vocal streak—but he’s friendly and well-mannered. He’s shown some interest in chasing cats, so to be safe, a feline-free home is best. Mylo has met children of various ages through his foster family and has done well overall. Due to his occasional jumping and enthusiasm, we recommend a home with older kids (10+) who are steady on their feet and understand how to interact with an active dog. He’s loving and playful, and with continued positive training, will only improve his manners. This boy LOVES walks and has a zest for getting out and about. He can pull on leash when excited, so a no-pull harness or Gentle Leader may help make walks more enjoyable. He’s fully house trained and has been trusted to stay loose when unsupervised, usually sticking to his gated area and dog bed like a gentleman. While he hasn’t been crated in his foster home, he’s done very well with the freedom and would likely thrive in a home where someone is around more often than not, or with a flexible schedule. Mylo is currently fed separately from the other dogs—not because he’s aggressive, but because he prefers not to share his snacks or special treats. (Honestly, who among us does?) With his people, though, he’s playful, cuddly, and incredibly affectionate. He greets his foster dad with enthusiastic hops and playful vocalizations, looking like the happiest dog in the world—with his tongue hanging out and his tail wagging in full swing. He’s also very smart and responsive to redirection. He listens when called, loves being praised, and wants so badly to be a good boy. Like many herding breeds, he thrives on routine and benefits from clear communication and a bit of structure. He may occasionally flinch at quick movements or new objects (like a broom), so a patient home that understands his background and lets him settle in at his own pace will help him feel his best. Here’s what Mylo is hoping for in his forever home: - A moderately active family with a yard or access to one where he can run, sniff, and sunbathe - A few good walks a day or fetch sessions to burn energy and keep him happy - A family who will give him tons of love, belly rubs, and attention - People who embrace his quirky personality and celebrate his uniqueness - Continued support with basic manners like jumping and treat-taking (he’s already working on it!) - A home with older kids (10+) and maybe a friendly dog buddy or two - And most importantly: a soft place to land and be loved for exactly who he is Mylo is a one-of-a-kind pup with a silly smile, a loyal heart, and so much love to give. He’s smart, affectionate, endlessly goofy, and ready to find a family who sees his magic. If you’re looking for a lovable sidekick who will keep you laughing, snuggling, and moving, Mylo might be the perfect match for you. ___ **Listed BREED and AGE - We are taking our best guess & recommendations from our veterinarian on age, breed and size when fully grown.
