Story

Cash is a great dog and is very friendly to everyone he meets. He spends most of his time laying on the front porch and sleeping by the fire at night. He has never gone to the bathroom inside and goes across the street to the vacant lot every morning. Therefore, you don’t have to scoop poop. Cash is easy to train doesn’t bark and loves being around people. We think that he is a Portuguese mastiff and his temperament is considered sober. If you are looking for a new best friend Look no further. We are relocating and can’t take him with us. He is the best pet I have ever had.

Meet Bakugo This handsome, sweet-natured pup is full of charm and personality. Because of his size, he’d do best in a home without young children, small dogs, or cats.

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 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!

Smokey

English Mastiff

Male, Adult

Richardson, TX

Size

(when grown) Large 61-100 lbs (28-45 kg)

Details

Good with kids, House-trained, Spayed or Neutered, Shots are up-to-date,

Story

Smokey is a 7-year-old, very friendly and outgoing boy with a heart full of love. He’s completely potty-trained, great with kids, and has lived with both men and women. Smokey spent most of his life as an outside dog, so he thrives in a yard where he can run and play freely. He has never been crated and would not do well cooped up in an apartment. He has shown some reactions to other dogs in kennels but did not react to cats he passed by—so he may benefit from meet-and-greets with other pets. Smokey is eager for his next chapter with a family who will give him the care, companionship, and freedom he deserves. Update: He has been treated for HW at the shelter **He is HW+, but you can foster to adopt , which means the dog stays with you until treatment is completed and they are cleared, at no extra cost to you. The dog comes off the adoption website once you are signed up for the foster to adopt program, or you can choose to go ahead and adopt, which at that point you are responsible for taking care of the treatment and the cost. Call the shelter at 972-744-4480 or email AskRichardsonAnimalServices@cor.gov to learn more.January 14, 2026, 1:07 pm

Story

Meet Canela â&#194&#128&#194&#147 Your New Best Friend! Hi there! My name is Canela, and I'm a lovable French Mastiff with a big heart and an even bigger love for cuddles (even though I'm a big girl at ~120 lbs!). I was rescued from DAS in January 2020, and my current family believes Iâ&#194&#128&#194&#153m about 7â&#194&#128&#194&#1478 years oldâ&#194&#128&#194&#148but donâ&#194&#128&#194&#153t let that fool you. Iâ&#194&#128&#194&#153m young at heart and still full of life! I adore being around people and thrive on companionship. Whether itâ&#194&#128&#194&#153s going for a walk, lounging around the house, or joining on car rides (my favorite!), Iâ&#194&#128&#194&#153m just happiest when Iâ&#194&#128&#194&#153m with my family. I'm not a fan of hot summer days, thoughâ&#194&#128&#194&#148give me a cool floor and a fan, and I'm golden. Iâ&#194&#128&#194&#153m potty trained and am trusted with free roam of the house. I know a few basic commandsâ&#194&#128&#194&#148okay, mostly just â&#194&#128&#194&#156sit,â&#194&#128&#194&#157 but I do it well! Iâ&#194&#128&#194&#153m spayed, so no puppies in my future, and I get along great with kids, seniors, other dogs, and even cats. Iâ&#194&#128&#194&#153m just that friendly. Some of my favorite things include: Soft jerky treats (beef, please!) PetSmart visits Riding in the car Dining at dog-friendly restaurants Cuddling on the couch Sadly, my dad is no longer able to care for me due to his health issues, and with a heavy heart, heâ&#194&#128&#194&#153s looking for a loving new home where Iâ&#194&#128&#194&#153ll be just as spoiled and cherished. If youâ&#194&#128&#194&#153re looking for a loyal, affectionate, and well-behaved companion, Iâ&#194&#128&#194&#153d love to meet you. Could I tag along on your next adventure? * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * If you have a specific question about Canela, then please email newdigs@dallaspetsalive.org.
