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 is looking for a home where he can be the one and only furry companion. While he’s shared space with cats and dogs in the past, his playful energy and enthusiastic spirit are best suited to a home without other animals. His size and zest for life can unintentionally overwhelm smaller pets, and he truly shines when he has all the attention to himself. In a home where he doesn’t have to share the spotlight, Huckleberry thrives! Soaking up affection, engaging fully with his people, and offering his goofy charm in every moment. 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 also open to a foster home, so if you're not ready to adopt but still want to make a difference, fostering could be a perfect fit. Reach out to adopt@joyfulpets.com to learn more!

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 ❤️🐾
