Rome is a wonderful dog and I love her but she hasn’t gotten the attention she needs due to our son who was born April last year and we had some lifestyle changes. She needs a home that will give her the attention she needs.

Story
A dog by any other name, just wouldn’t be the same! Fantastic Mr. Fox, referred to as FMF or Fox, is a 6 year old (almost 7) Chihuahua mix. He came to MHCR as a transfer from a local CO shelter in February of 2025. He spent the next 10 months completely kicking our a$$e$ with his allergies and trying to get them under control. AND WE HAVE SUCCEEDED. This guy is, you guessed it, fantastic. He’s been totally worth the effort and we couldn’t be more thrilled to finally list him for his true forever home. He’s on a strict diet and requires daily meds to maintain this luxurious coat and to keep his skin fully intact. Fox is around 12-13 lbs. He loves wearing clothes and fully expects a nice wardrobe from his forever humans. He is great with dogs and cats of all sizes and has proven himself to be house trained. Are you in school? Perfect! He wants to eat your homework. If you aren’t into that you can simply crate him, but be warned, he will protest that a bit in the beginning. Fox likes car rides. He enjoys walks and stroller rides. He’s never met a stranger and is quick to warm up to new peeps he meets. He has bursts of play, but LOVES snuggle time under ALLLLLL the blankets as any good chi should. We have worked closely with Mr. Fox’s regular veterinarians as well as a dermatology specialist at CSU (🙏🏻) to come up with the right blend of meds and food to keep this boy comfy and healthy. He takes Atopica, prednisone, eats a strict prescription diet, and has an even stricter list of treats – with this kind of treatment you’d be surprised he isn’t royalty. We are happy to report, we’ve spent months monitoring his bloodwork and his body has finally taken kindly to the program. Mr. Fox, unfortunately has had a handful of seizures while in our care over the preceding 12 months. At this stage he does not require medications however it is something he may need additional support with in the future. We aren’t looking for just any home. We are looking for the right home. While there are many shapes and sizes, one thing is for sure, FMF’s forever peeps shouldn’t be opposed to a dog will have some medical needs. He promises to pay them back 10 fold, though. Fantastic Mr. Fox is in foster in Black Hawk, 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/fantastic-mr-fox You can apply for our wonderful dogs at https://www.milehighcanine.org/adopt/adoption-application/.

Story
"🐾 Meet Henry Henry is a 1‑year‑old pit mix from Houston with a heart as big as his blocky smile. He’s the kind of dog who makes instant friends—incredibly dog‑friendly, playful, and always ready for a good wrestle with any pup who’s up for it. 💛 A Tough Start When Henry first entered the shelter, he was severely emaciated, battling mange, and so malnourished that his body was weak and his conformation was poor. Despite everything, he greeted people with gentle eyes and a quiet hopefulness that made it impossible not to root for him. 🌱 Growing Strong in Foster Since entering foster care, Henry has been steadily rebuilding his strength—and his spirit has absolutely blossomed. His coat is healthy, his energy is up, and he’s discovering how fun it is to be a young dog with a safe place to land. He’s gained nearly 15 lbs since his arrival to MHCR! Henry visited an orthopedic specialist, who confirmed he’s orthopedically sound. His gait is just a little “wonky” from his early malnutrition, and as he continues to gain muscle, his legs are expected to continue to improve. 🎉 Who Henry Is Today Playful, social, and joyful with other dogs Resilient and affectionate, with a soft, eager-to-please temperament Growing stronger every day, both physically and emotionally Ready for a family who will celebrate his progress and give him the love he’s always deserved." Henry is being fostered in Aurora, 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/henry/.

Story
"William is a petite, spunky, 35 lbs, mixed breed boy that’s around 3 years old. He was an unclaimed stray and found himself in the wrong place at the wrong time at a high kill shelter. William scored a ticket to Colorado on Valentine’s Day has recently made his arrival. He is an easy going guy for his foster family to have around while he waits for his forever family. William is smart, friendly, and social. He loves people and treats, walks nicely on a leash, and enjoys a good car ride! He also keeps a clean crate and sleeps through the night. William likes playing with other dogs, though he does like to sass them and tell them what to do 🤣. He’s pretty unapologetically opinionated and not shy about expressing what he wants. William did test positive for heartworm and is being treated. He has no idea he has those extra pesky passengers through and thankfully feels great and healthy; ready to put his old life behind him. His ideal family will give him furniture privileges and snuggles and let him be included in as much of their lives as possible as the cutest friend, co-pilot, and shadow ever. Where there’s Will, he will 100% find a way!" William is being fostered in Fort Collins, 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/william/.

Story
Millie is a year old girl with all the house manners and plenty of zest for the active Colorado outdoorsman! She’s house trained, rides well in the car, is dog friendly, greets strangers with a smile, and has an independent streak. She likes to explore, take scent walks, and enjoys a good game of fetch — she casually drops the ball back near you while jogging past. Millie is around 55 lbs. She joined MHCR from a high intake shelter in Texas where she found herself on the euthanasia list due to lack of space. Millie left Texas with a few heartworms in tow, as lots of Texas dogs do, but not to worry, she’s being treated and these will soon be a thing of the past. Feline and poultry free home for her, please! Millie is being fostered in Longmont, 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/millie/.

Story
"Meet Sugar — a 2-year-old female Great Pyrenees mix with a heart as big as her fluffy smile 🤍 At 59.4 lbs, Sugar could stand to gain a few more pounds, but what she may lack in fluff right now she more than makes up for in pure sweetness. This girl is happiness on four paws — her tail is always wagging, she gives the very best kisses, and she’ll happily follow you from room to room just to be near her people. Sugar loves everyone she meets and does wonderfully with other dogs. She walks beautifully on leash — no pulling, no reactivity — just happily moseying along, stopping to sniff absolutely everything (because the world is fascinating, obviously 😄). She appears to be potty trained and has great house manners. Crates aren’t her thing — they’re actually pretty scary to her — but the good news is she’s completely trustworthy free roaming, so there’s no need to push it. She settles nicely in the home, enjoys playtime and the occasional burst of zoomies, but is just as content to lounge and relax by your side. If you’re looking for a loving, gentle, easygoing companion who will adore you endlessly and bring a constant wag to your life, Sugar might just be your perfect match 💕" Sugar is being fostered in Firestone, 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/sugar/.
