Story
🚨 URGENT: HANSEL & GRETAL NEED A WAY FORWARD—TOGETHER 🚨 Hansel and Gretal are a bonded Mastiff pair whose family is facing more than anyone should have to bear. Their dad passed away from cancer, and now their mom needs back surgery. She is having trouble walking and can no longer manage their care on her own. She is desperate for help finding a safe solution for them. This isn’t a family giving them up because they stopped loving them. It’s a heartbreaking situation that has left their mom needing support and Hansel and Gretal needing a new place to land. They’ve already lost their dad; they deserve the comfort of staying together as they face this next change. Please help Hansel and Gretal find a home—or the support they need—so they don’t have to be separated. They need someone willing to give this devoted pair a chance and help them through a difficult transition. Their family is asking for help, and time matters. ❤️🐾 PLEASE HELP TEXT KAREN 4136298152

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.October 10, 2026, 5:57 pm

Story
Hubert is a loving, affectionate 7 year old St. Berdoodle looking for the right forever home. He loves playing fetch, going for walks, and curling up for cuddles. He's 55lbs., 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.
