Story
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!

Story
Hazel is a loveable loaf in search of a comfy couch to snuggle on! She`s sure to charm you with her adorable personality and stunning brindle coat. Hazel isn`t a fan of sharing her yummy bones with other animals, so she is required to be the only animal in her next home so she can be spoiled rotten with snacks and affection! At this time, HSBV is also requiring a home either without children or with children over the age of 10.

Story
Mylo is an amazing dog, super friendly and easy going. Somewhat lazy but loves to play fetch from time to time or roam a field. He’s old and hard of hearing but great with all people and pets. He’s a tad overly friendly but likes to snooze most of the day. He still has lots of life to live and has been pretty pampered most of his life ! He Loves being near the kids and action of the day. Since relocating to a state with more sun he’s found a love for sunbathing. His one true love is open space and snowballs when available. He’s been an amazing part of our family but our current dynamic is not what’s best for him or our family sadly.
