Hi, I’m Bruno (59734105), a 1 year old Mastiff mix hoping for a loving, caring family to call my own. Just like my friends Rosie and Nala, I missed quite a few meals, and I dream every day of a life where I’m cared for, cherished, and my belly is  always full. I’m a timid boy, but I’m incredibly sweet, and treats are definitely my love language. I’m ready for my second chance ... is it waiting with you?   Check out all the adoptable animals on the shelter's website! https://www.collincountytx.gov/Services/Animal-Services/adoptable-pets All adoptions include spay/neuter, microchip and first round of vaccinations.

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
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? Reach out to adopt@joyfulpets.com to learn more!

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

Story
Peaches is a 1–2-year-old spayed female full Saint Bernard.  They have her birthday listed as September 2024. However, we really don’t have 100% confirmation that that is correct.  Miss Peaches should have been named Mahogany. She has the most gorgeous, thickest plush coat that we have ever seen on any Saint Bernard.  Miss Peaches is sweet, kind, loving, gorgeous and a joy to be around.  She is 100% house trained and loves attention.  She knows basic commands; however, more training is always recommended, both for the dog as well as building a bond with the new owners.  She weighs approximately 100 pounds and has received all of her shots.  However, she is heart worm positive.  We have started her on the slow kill method of getting rid of heart worms.  This will take anywhere from 6 months to a year to complete.  This is a much more humane and safe process.  She has received all her vaccinations.  If you are wanting one of the most gorgeous Saint Bernhards that we have ever had, please consider meeting Miss. Peaches. 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.
