Meet Tiny 🩶 This handsome smoky-grey Mastiff mix boy is about 20 weeks old and already stealing hearts everywhere he goes!

His easygoing personality makes him a wonderful addition to just about any home ready for a growing pup. (baby shark teeth included!) Tiny will grow into a large breed dog, and he’s already practicing with those adorable meaty paws — perfect for anyone who appreciates a big-pawed best friend! If you’re looking for a joyful, affectionate companion who will grow up to be your loyal shadow, Tiny just might be your big boy!

Story
Meet Diamond!Diamond is a 5-year-old English Mastiff with a heart as big as her paws. This gentle giant may show a little “stranger danger” at first, but don’t let that fool you—once she feels safe, she absolutely shines. With a few tasty treats and plenty of praise, Diamond’s sweet, affectionate personality truly glows.Diamond is looking for an adult-only home (no kids under 18) where she can feel secure and understood. Because she can be wary of new faces, she’ll thrive with patient adopters who are willing to let her warm up at her own pace. Once you’re in her circle, you’ll see just how loyal and loving she can be.She would prefer a home without cats. Diamond is open to meeting calm, respectful dogs who won’t be too pushy or in her space. In fact, she previously lived successfully with a male Chihuahua and did well with that dynamic!If you’re ready to give this shining gem the time and trust she needs, Diamond will reward you with unwavering loyalty and love. Come meet her and see how bright your life could be with Diamond by your side.
