Story
Meet Nala, a 4-year-old, female, Mastiff with a heartwarming story. After a life of being bred, Nala found her way to MHCR from a rural shelter in NM. Now, in her retirement, she’s looking for a loving home where she can enjoy a slow-paced, calm, and relaxing life. With her nurturing history as a mama to many pups, she deserves all the care and comfort in the world. Nala weighs approximately 125 lbs and could benefit from shedding a few pounds to maintain her health. She’s a friendly and gentle soul, likely to do well with kids, although she would prefer a home with less chaos. Nala is already house trained and appreciates having a crate available for those moments when she wants to rest and feel secure. If you’re looking for a loyal companion who will thrive in a serene environment, consider opening your heart and home to Nala. She’s ready to embrace a new chapter filled with love and care. Nala is in foster in Centennial, Colorado. *We require all adopters to come to Colorado to adopt. *We do not transport dogs. * You can view this wonderful dog at https://www.milehighcanine.org/post/dogs/nala.

Story
Bacchus is a FANCY boy! He’s approx 9-years-old and was surrendered by his owners in Texas for “getting too old.” We just can’t even believe it because his perfectly salt and peppered face is a DREAM! We couldn’t stand not knowing for sure, so Bacchus’ foster mom ran a DNA test and we discovered he’s from very recent South African lines. He’s neutered now, so it’s not that big of a deal, but don’t tell him that because he still thinks it’s a pretty big deal. Bacchus, despite his age, is quite playful, and when he’s not on crate rest due to heartworm treatment, he enjoys playing fetch down the hallway and wrestling around with his canine lady friends. He’s a very sweet, cuddly boy and it’s quite apparent that he was well cared for prior to being surrendered (minus the pesky heartworms). He’s very well socialized to humans and does well with other canines. We’re hopeful to find an excellent retirement home for him that will love him because he’s old and wonderful! Bacchus is in foster in Castle Rock, Colorado. *We require all adopters to come to Colorado to adopt. *We do not transport dogs. * You can view this wonderful dog at https://www.milehighcanine.org/post/dogs/bacchus/.

Story
Bren is a 1-2 year old, large, mixed breed guy that’s great with dog friends. He’s in need of a foster home before he heads to CO. Fostering is a commitment to the dog to stick by them until a forever home is found. This can often include teaching them the ins and outs of living in a home, sleeping in a crate, and mastering household manners. Apply to foster here: https://www.milehighcanine.org/foster/.

Needs experienced adopter,
Story
Brutus is a very high energy puppy. He is very deserving of a family that can keep up with him and have a yard (I currently do not). He's super smart and overall a really great dog. Sit, stay, lay down, shake, crate trained, good off leash, potty trained, not food aggressive. The only thing is he will need some social training. Thank you for reading. And please give this big boy a chance. I hate to see this goober leave.
