Story
This friendly, easygoing guy has a calm, independent charm. He enjoys exploring the world at his own pace, especially when there are good smells to investigate, and is happy to share affection when he’s in the mood. He’s polite and neutral around other dogs and would do well with a family who appreciates a more laid-back companion that values both adventure and quiet independence.

Story
Meet Rex, our 98-lb gentle giant with a heart just as big as his blocky head. This stunning red Mastiff mix, just under 2 years old and already neutered, is the total package he is calm, polite, intelligent, and just the right amount of goofy. ✨ Why Rex is amazing: • Walks beautifully on leash • Knows “sit” and takes treats with a soft, gentle mouth • Affectionate once he warms up • Loves walks, lounging, and hanging with his people • May be cat workable with slow and proper intros 🐱❤️ In playgroups, Rex enjoys gentle play with both male and female dogs who don’t mind his big-dog enthusiasm. He thrives in a calm, structured home without too much chaos just a loving person or family who sees what a treasure he is. Neutered| 2 yrs old | 98 lbs | Mastiff Mix
