Story
Handsome Gumbo! This sweet boy is searching for a new home, could he be the right one for you? Gumbo loves pets and people, but can get overwhelmed at times and will benefit from an adopter that can support him when he needs it! He has also enjoyed the company of other dogs and might do well in a multi-dog home. At this time, HSBV will only rehome him to a family either without children or with children over the age of 10.

Story
Uma is an approximately 9-year-old Mastiff mix with the gentlest heart. She is a giant cuddle bug who believes she is a lap dog and loves nothing more than being close to her people. Uma is sweet, calm, and incredibly affectionate. Uma was adopted as a rescue, and her early life was difficult. Because of past trauma, she can become reactive on walks, but with a proper harness and mindful handling she does very well. She has lived peacefully with dogs, cats, and children of all ages, including babies, whom she absolutely adores. Slow introductions to new animals may help her feel safe, but she has never harmed a person. Mastiffs have relatively short lifespans, and our greatest hope is to find Uma a loving home where she can spend her senior years surrounded by comfort, affection, and family.

Story
Hi, I'm Jax! I was surrendered to the Pet Assn. after my owner became unable to care for me and my two "siblings" (Joplin & Jypsy). I'm a 5 year old Mastiff/Rotty mix and am just the most gentle giant. I am nearly 75lbs, great with kids, cats, and other dogs. I am crate trained, housetrained, easy on leash, good in the car, know basic commands, and really am just a big love bug. If you're looking for a big grown pup with good manners, I'm your guy! Reach out to meet me!

Story
Hi, I`m Bonsai! I came into the shelter all by myself so no one knows my history. I can be a little shy at first, warm up quickly, lean in for pets and I know `sit`, `down` and possibly `shake.` No idea how well I would do around kids, cats or small animals and I can be a little uncomfortable around other dogs. Some slow introductions, letting me opt out, and building positive associations will really help me! I`m not currently in view, but please do ask to visit with me as I have been available for almost two weeks!

Story
Daisey is a beautiful 6yr old English Mastiff who hails from Oklahoma and is timid at first but loves the loves when she warms up. She is a sweet, quiet companion who doesn’t really understand a true family home life (yet). She is still figuring it out, as she desperately wants the connection, but hasn’t had it before as she was a former breeder mamma. When she was of no more use, they took her to a kill shelter where Big Bones stepped in and brought her here to Colorado for a fresh start on life. She is learning new things like stairs and bath time. She is good with dogs, and has made friends with her foster canine siblings, and is such a sweet girl. If you are looking for a no frills, low maintenance type of dog, Daisey is your best bet.
