Story
Tiana, your very favorite princess, is searching for her forever castle! I'm a gorgeous, gorgeous girl, and about 5.5 years young. This means I'm past my puppy craziness, but still have plenty of life and adventure left to live with you! I'm a bigger gal, around 70 pounds, but that's all the more to love you with! I already know some tricks, like sit, stay and paw, and am ready to learn more! I was brought to the shelter when my human was moving, but I'm taking the change in stride, and can't wait to get back into a home with some people who will love me! I did well with housebreaking, crate training, and exploring all of the world with my family. I love all humans I've come across, and I know I'll love you, too, if you come meet me!   Have Room in Your Home? Welcoming in a pet saves your new pet's life and creates space for another pet to get a chance! Not sure if Tiana would be the best fit for you? Send in a generic app! Our team will work with you to find a pet to best fit your lifestyle! You will go home with a starter bag of food, one month of flea and heartworm prevention, and also have 90 DAYS of training help included with your adoption, if needed!

This is Buc, he is a mixed breed pup about 3 yrs old. His owner passed away and his wife was unable to keep him. Buc is up to date on vaccinations, fixed and house trained. He loves kids. He plays very well with other dogs. He loves being outside and has done very well with positive training so far. He is a very sweet boy with lots of kisses to give. Buc has lots of energy and is a little unaware of his actual size. He’s quite adorable. This good boy needs a place to call home! He would do well in a home with other large size dogs.

Hello there, I`m Melvin! I`m a sweet soul with a dash of goofiness. My curiosity knows no bounds, and I love exploring new places. I`m brave, too! Nothing scares me, except maybe the vacuum cleaner. I`m also smart, I`ve mastered sit, stay, and fetch, and I`m always eager to learn new tricks. I`m energetic and playful, ready to run and play fetch any time you are. I`m a loyal companion, always ready to lend a paw or a comforting nuzzle. I`m just looking for a loving family who appreciates my playful spirit and endless curiosity. Why should you adopt me? Well, I promise to bring joy, laughter, and lots of tail wags into your life. Let`s make some memories together!
