🐾 _Meet Maxine!_ 😍 This gentle giant is a sweet 3-year-old, 66-pound Mastiff mix with a heart of gold. Pulled from a shelter's at her final notice, she's now ready to shower YOU with love 🐾💕. Playful with humans and pups alike, Maxine's favorite thing is snuggling up for hugs and smacks. As a volunteer's fave at the shelter, she'd brighten anyone's day. Ready to make you her person? 😁 Let's get Maxine home!

Hi! I’m Bronze. I am a chill kinda pup but I do get the zoomies and LOVE to run with my toys. My foster mom says I give really good kisses but I would rather you kiss on me. ❤️ I am learning to do my business outside but my foster mom says I am a work in progress. I have found this hole in the wall (a doggie door) that lets me go outside. Really cool! I know there is a family out there that is looking for a  warm hearted loving pup. I will brighten your day with all my love I have to give. Come meet me and take me home I’ll be waiting for you!

This enormous guy is Wario! He may be huge, but he is the epitome of a gentle giant. He is sweet, easy going, mellow and loves fetch. He also seems to get along with other dogs but may be too large for small dogs or cats!
