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!
