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!

Meet Judge Age about 4 100lbs Neutered Male Fluffy big-headed sweet lover-boy has officially arrived in Colorado, ready to start his journey to good health and fun! Judge came into the shelter a few weeks ago after being found severely injured. A neighbor reported that he had been attacked by another dog down the street.

He is a big, beautiful boy with so much love to give. **Great house manners, potty-trained **Loves car rides **Enjoys toys, food, and fun! **Leash trained; albeit his medical issues, that are currently being addressed limit his mobility, but he will be ready to explore when healed. **Very engaged, eager to please, will be so fun to train (treat motivated). **Currently living with female dog friend and is doing great, enjoys her company, shares toys, no food aggression whatsoever. **True to breed, he is a vocal observer, will likely need a home without shared walls. **Medium energy, can't wait to see him able to freely move about.

His coat is so soft and he has so much love to give his new family. No exposure to cats/kids, but will be working on that. He's just a big teddy bear! More details to come.

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.
