Story
After 18 months of waiting, McDuff is finally ready for his forever home! At 3 years old and about 50 pounds, this Lab/Mastiff mix is a "velvet hippo" with a heart of gold. He’s a total shelter favorite known for being sweet, gentle, and having a tail that never stops wagging. He rarely barks and loves everyone he meets! He is active and strong. Because of that we would recommend children 10 and up. McDuff is a social butterfly who does wonderfully with cats and other dogs. While he’s still working on his leash manners and learning not to jump when he’s excited, he’s already mastered "go lay down" and is eager to please. He just needs a patient family to help him transition into home life. Let's make McDuff's dreams come true—he’s waited long enough for a family to call his own! With ongoing training he is going to make someone a real special traveling companion, and hiking companion. Adoption fee is $475 If you do not hear from us within 7 days please email passion4petsrescue@gmail.com

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.
