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
"Are you looking to rescue a nice dog that is out of the puppy stage? Then STOP SCROLLING! Meet Pearl! She is a very sweet middle aged (5-7 ish years) lab/shepherd type mix who is 52 pounds and is just waiting for a forever family to notice her. We don’t know her story before she was picked up as a stray in Houston with heartworms, but it is evident that she was well socialized and has lived in a home before. She was clearly a mama and is mellow, with a special kind of wisdom about her. Pearl had excellent behavior notes in the shelter— non-reactive to other dogs, quiet and calm, keeping her kennel clean, going potty outside, walking nicely on leash, and being friendly with all the staff/volunteers. We are so glad we chose her! Pearl is so excited for her new lease on a better life. She’s a diamond in the rough and her forever family will be lucky to have found her. She’s the low-maintenance type: a couple meals a day, a comfy bed, and occasional walks/strolls. Pearl is a healthy girl who is now spayed and kicking her heartworms to the curb, so she is ready for adoption and has much more life left to live!" Pearl 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/pearl/.

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 Coco! 🐩✨ Coco is a 3-year-old poodle mix with a bouncy step and a heart full of sunshine! This happy girl is incredibly people-oriented and thrives on being part of the action. Whether you’re moving around the house or relaxing on the couch, Coco wants to be right there with you. She’s potty trained, crate trained, and walks nicely on leash. While she can occasionally be a little startled by new things, she quickly looks to her person for reassurance and guidance — she really wants to connect and trust her handler. One of her cutest (and most impressive!) traits? She can jump waist high just to say hello and grab your attention! She’s agile, athletic, and would likely enjoy activities that let her show off her skills. Coco can be bossy and territorial with other dogs and would thrive as the only dog in the home. A no-cat household is also recommended. If you’re looking for a lively, loving companion who will keep you smiling and always want to be by your side, Coco might just be your girl! 💕" Coco 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/coco/.

Story
Meet Roy Kent 🐾 At 12 weeks old, Roy Kent the dachshund mix is the cool, independent little brother with plenty of personality. While he enjoys affection, he’s not quite the full-time lap dog like his brother — Roy prefers to keep things on his terms. He’ll come check in for pets, then bounce off to handle important puppy business. Roy loves toys just as much as the next pup and is always ready for a playful romp. He’s curious, observant, and a little more thoughtful before diving into new situations. Don’t let that fool you though — once he’s comfortable, his silly side shines! Blanket burrowing? Absolutely. Treats? Yes, please. Stealing your stuff? If it’s on the floor, it’s fair game. 😉 Roy would do great with a family that appreciates a pup with a slightly more independent streak — one who bonds deeply but doesn’t need to be glued to you 24/7. He’s got confidence, charm, and just the right amount of sass to keep life interesting. 💙 Roy Kent is in foster in Lakewood, 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/roy-kent You can apply for our wonderful dogs at https://www.milehighcanine.org/adopt/adoption-application/.
