Story
Hello there, I'm Mark! I may be young, but I've got a heart full of love to give. Every morning, I wake up excited for the day ahead. I love playing with my favorite chew toy, but what I really crave is a good game of fetch with a human friend. I'm a quick learner, too! I've already mastered 'sit' and 'stay', and I'm eager to learn more. I promise to be your loyal companion, always ready for an adventure or a cozy nap on the couch. I'm not just looking for a home, I'm looking for a family. Adopt me and let's create a lifetime of wonderful memories together.

Story
Cooper is a big, handsome guy looking for a home of his own. He loves to go for slow, sniffy walks or have a quiet, comfy place for a nice nap. He really likes getting treats, so he is a great training buddy. Although he is so big and strong, this guy walks very nicely on a leash. In his previous home, Cooper had good house manners and lived with kids. Cooper is not very comfortable around other dogs so he would likely do best in a home where he was best and only dog. Cooper can also be worried around new people so he is looking for a quiet home where he can settle at his own pace. He may not be ready for pets right away, so he hopes his new adopters become well versed in reading doggy body language. This big beautiful dog is having a tough time at the noisy shelter. Would you like to help him out? Come meet Cooper.

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 6, 2026, 1:58 pm
