🐾 Sweet, Trained Dog “Milo” Looking for His Forever Home 🏡❤️ Meet Milo — a gentle soul with a big heart and an even bigger smile. Milo has come such a long way and is now ready to find the loving forever home he truly deserves. Milo is a young, well-mannered dog who has completed professional training in both behavior and obedience (all paid and up-to-date). He knows his commands, listens beautifully, and thrives on routine, patience, and affection. His trainers describe him as eager to please, loyal, and deeply affectionate once he bonds with you. He enjoys long walks, belly rubs, and being close to his people. Milo has a calm energy indoors but is always up for playtime and adventures outside. He’s crate-trained, house-trained, and responds very well to gentle leadership. Milo has worked hard to become the wonderful companion he is today — now all he needs is someone who will give him the love, time, and stability he’s earned.

Story

I’ve had atlas since he was 6 weeks old. He’s almost a year and a half and weighs over 100 pounds. He’s 64% English mastiff, 26% blood hound and 10% boxer. He’s got a big personality, he needs a little space to run, he knows some basic commands but needs a little more training, he loves to play keep away with his blanket and toys, he’s a very sweet boy and he loves to know what you are doing at all times. He is an indoor and outdoor boy. If he’s outdoors he sits at the window waiting to come inside. Atlas is very loving and wants to be in your lap even if your lap is lower than his head. He’s a very good boy. I’m not looking for any adoption fee. I just want him to have a great home to call his furever home.

Story

Meet Huckleberry! A spirited two-and-a-half-year-old Mastiff/Labrador Retriever mix currently in Edmond, OK, whose essence is a whirlwind of joy wrapped in a sturdy white and gray frame and powered by endless enthusiasm. Huckleberry is a big-hearted, big-footed goofball who lives for fun, fresh air, and friends! We’re talking high-octane fetch sessions, tug-of-war tournaments, and “keep away” games that will keep you on your toes (and laughing out loud!). He’s also a big fan of car rides and pup cups, just say the word and he’s leaping in the back seat like a seasoned road tripper. People? He adores them! Kids over seven? Absolutely! He’s happiest when surrounded by love, play, and plenty of activity. At 60 pounds of pure lovable energy, Huckleberry thrives on structure and routine. He’s house and crate trained, knows commands like sit, heel, stay, and wait, and completed several weeks of training at K9 University. He’s a quick learner and will work for treats every time, though he may test your consistency now and then. Huckleberry enjoys the company of other dogs with slow, proper introductions, but would also be perfectly content soaking up all the attention as the only pet. He’s lived with cats before, his playful nature and size can be a bit much for them, so gentle introductions are a must. His energy can sometimes overwhelm smaller animals, but his intentions are as pure as they come. He’s a strong jumper, so a fenced yard is a must. He needs plenty of exercise and stimulation to keep his mind and muscles happy. Touching his paws makes him a bit uneasy, so patient, low-key vet visits are best. Are you ready to welcome a goofy, loyal, and utterly lovable companion into your life? Huckleberry is waiting to meet his new family. Could it be you?

Story

BAKUGO 🐾 Gorgeously sweet pup @ just 3 years old! He has to learn to trust men again but is doing amazing with training and has shown so much improvement! Because of his size no young/small children or dogs/cats. Older kids who know to respect his space would be okay. He is a BIG Sensitive guy with a charming personality. Doesn’t love living in a crate as he prefers to be hanging out with his person! Will go in an indestructible crate but it’s not his favorite 🤣 Very treat motivated and eager to learn! LOVES the lake, to go for walks and truck rides!! With continued training and an assertive owner he will thrive in a new environment but will need slow introductions to new people. Everything is very scary to him at first, poor guy! House Trained - will not potty in the house when left out or in his crate! Fully vaccinated Neutered Current on Preventatives Still undergoing training with foster ❤️🐾
