He will bring you a rock a stick a ball just a super chill easy-going boy that deserves a happy forever home. Meet Tiki! 🐾💙 Born in May 2023, Tiki had a rough start — he and his litter were dumped with their mom, umbilical cords still attached. His whole family has since been adopted, except for Tiki and his brother. Now it’s his turn to find a forever home! Tiki is fully vetted and even passed his temperament test with the Veteran Association. He’s wonderful with other dogs and children, making him an all-around good boy.

Story

we rescued new born pups and a mama husky that bred by accident w the neighbors mastiff. These 2 boys are gorgeous and so smart and sweet, they love to swim and fetch and play they will make a great companion for the family, two-year-old. Neutered and fully vetted Meet Sampson! 🐾💛 Born in May 2023, Sampson is the bigger brother at 95 pounds — a sweet, gentle giant with the softest heart. Just like his brother, he’s fully vetted and even passed his temperament test with the Veteran Association, showing just how smart and steady he is. Sampson can be a little shy at first, especially about car rides (he may need a boost in), but once he’s settled, he rides just fine. He’s a playful boy who loves to run, splash around, and has the most adorable habit of blowing bubbles in the water! With his floppy ears and soulful eyes, he’s as handsome as he is lovable. This sweet guy deserves a family who will cherish him, give him room to stretch his legs, and let his affectionate personality shine. Could Sampson be the one to fill your home with joy?

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.
