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
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
Please contact Tammy for more information about this pet.Easy-going family man    Meet Hector – The Easygoing Senior Who Makes Everything Easy Hector is 10ish, and his foster sums him up best: he’s a good boy who makes everything easy. What he wants most is simple: to be wherever you are. If you’re looking for a calm, settled companion who’s past the puppy chaos and ready to be your shadow, Hector may be your guy. Fair warning: Hector has never heard of personal space at mealtime. Like most of us as we age, food is everything. Eat on the couch and you’ll have a 70-lb dinner guest gazing up at you with total sincerity. Hector at a Glance: Age: 10 years Weight: ~70 lbs Temperament: Good with kids and dogs with proper intro. Not a fan of cats.  Training: Housetrained / crate-trained Health Notes: Neutered, up-to-date on vaccines/preventatives; Senior bloodwork in July came back looking really good for his age, and while his hips and elbows creak a little, a monthly (or so) Librela injection keeps him comfortable and moving well. See his latest videos: bit.ly/findhector Questions? jamie@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! Doggie Harmony is a pet placement and matchmaking service that works with community members who are already housing a pet. Interested adopters are asked to apply at doggieharmony.org/forms and allow a home visit, so we can make sure each pet is a great match.  Please ask the pet’s current caretaker directly about their return process, and request an adoption contract. While we can’t offer immediate intake for dogs that need to be returned, we’re always happy to help a family rehome a pet while they continue to care for it.  Every match keeps a pet out of Georgia’s overcrowded shelters, where more than 30,000 dogs and cats are euthanized each year.
