Story
We're needing help finding a home for our sweet big dog, Hank! He's 9 years old, mix between English Mastiff and American Staffordshire. Big boy close to 150lbs, but he's really just a sweet toy-loving dog who likes to play and lounge about. He lives in an apartment now but his heavy walking and tendency to play loudly with his toys led to too many noise complaints, and we'e only been given a couple of days to find him a new home. We wish we could keep him in the family, we love Hank so much. He loves going to the dog park and lounging about and playing with his toys. We rescued him from an abusive household just before 2 years old, so some forms of touch he doesn't like, you just have to be mindful and not overwhelm him. Sometimes kids can overwhelm him and also aggressive dogs. But he is totally fine with strangers and people love him. He's a great dog.

Story
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. Bakugo is a sensitive soul who loves being close to his person and isn’t a fan of spending time in a crate—he’d much rather be your constant companion. He’s house-trained, vaccinated, and neutered, and is ready to bring love and loyalty to his forever home.

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 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!

Story
Hanky Panky is one of those Saint Bernards that we will never forget for the rest of our lives. He has the temperament and look that every Saint should have. He is not a young boy, but he is not an old man. He has a beautiful short hair coat. We think he is approximately 5 years old. Hanky Panky loves attention, will walk right by your side, knows how to sit and is great with all dogs. He will make you smile every day. He weighs 135 pounds, and he is heartworm positive. St Cloud’s rescue has already neutered him, and he is on the slow kill method for the heartworms. This will take between 6 months to a year to complete. He is having some intestinal issues that may be due to his medication for the heartworm treatment. He is house trained. He does have a sensitive stomach and we are working to find the food that works best for him the best. He should weigh about 150 pounds when he is healthy and eating properly. He loves toys but he can’t have toys because he has a tendency to eat them. In concern for families with small children, we will not adopt a dog to a home with any child under the age of 5. This is due to the large size of Saint Bernards and the safety of your children. Our Saint Bernards are not aggressive or mean in any way, they can just knock down children easily. If you would like to visit our pups please contact St. Cloud's Rescue at www.stcloudsrescue.org or call 972-679-5319. The first step in adopting from St. Cloud's Rescue is to complete an application. The application may be found OUR WEBSITE at www.stcloudsrescue.org. Please click on the application process, complete and then email it. Once the application has been sent please call us to confirm that we have received it. St.Cloud's Rescue maintains the right to deny applications to anyone for any reason we see fit. St. Cloud Rescue is a non-profit 501-c-3 organization. St. Clouds Rescue requires new owners to purchase a one year supply of heartworm preventative from us, which is at cost. We require a home visit prior to all placements. All our dogs must be microchipped at a cost of $20.00. There is a $350.00 donation fee. All dogs adopted through St Clouds Rescue must be indoors. Saint Bernards can not tolerate the Texas heat.

Nana is the mother of Sullivan, the 7-month puppy. Both were found to be strays. Nana weighs approximately 110 pounds and has a beautiful rough coat. She is spayed, current on all vaccinations and heartworm negative. She does have an extra long tongue which she was either born with or it was due to trauma sometime in her life. It does not affect her ability to eat or drink, she just has a very long tongue. She is approximately 2-3 years old, has a great disposition and is ready and looking forward to finding a wonderful new forever-home.
