Story
Please contact Tammy for more information about this pet.Easy-going family manA Letter from Hector To My Future Family… Hi, it’s me—Hector. You may not know me yet, but I’ve been waiting for you. I’m 10 years old, around 70 lbs, and I’ve spent the last 3 years hoping someone like you would come along. I’ve had homes before… some good, some not so much. I’ve been returned, lost, and forgotten. Once, I even walked myself back to the shelter gates because, deep down, I knew I deserved better. And I still believe I do. I’m not asking for much—just a soft place to land and someone who means it when they say “forever.” I’m house-trained, crate-trained, and I know my commands. I also just got a great health report from the vet. Aside from a little arthritis, I'm healthy as a horse. Yeehaw! I love snuggles, slow strolls, and feeling like I belong. I’m gentle with people and can live with sturdy kids. I get along with some dog friends too—just no cats, please. My caretaker says I’m loyal, low-key, and full of love. I just need a home where I can finally exhale and know I’m safe. Where I can lay my head down and not worry about being left again. So if you're out there—my person, my family—please come find me. I've waited a long time, but I still believe you're coming. Love, Hector See my latest videos: bit.ly/findhector Questions? adopt@doggieharmony.org Apply to adopt: www.doggieharmony.org (click Forms) Even if you can’t adopt Hector, please share his story. His forever is out there—we just have to help it find him.August 14, 2026, 1:12 pm

Story
Hubert is a loving, affectionate St. Berdoodle looking for the right forever home. He loves playing fetch, going for walks, and curling up for cuddles. He's energetic, goofy, and happiest when he's with his people. After a good play session, he's content to relax by your side.We have a young child and can no longer give Hubert the love and attention that he deserves. We're committed to finding the best match for him and we believe he'd do best in a home without young children and preferably as the only pet or with an experienced owner who can manage introductions and high-value items.This is an incredibly difficult decision, and our priority is finding Hubert a safe, loving home where he can thrive. If you think you may be the right fit, we'd love to tell you more about this wonderful dog.
