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 Tim, a big personality crammed into a teeny tiny 6–7 lb body. At 5 (almost 6), this little Chihuahua is sensitive, cautious, and learning to trust at his own very slow, very Tim-approved pace. He is adorable, expressive, and fully committed to doing things his way. Tim is a fearful little guy and will need a patient, adult-only home that understands this is a long-term trust-building situation. He does not like being picked up, will not allow a leash to be put on him (unless you can distract him with treats), and it will take a good amount of time before he is comfortable with petting. Even once he warms up, affection happens strictly on his terms. But when he chooses you, it feels like winning the lottery. Now for the fun part. Once Tim truly trusts someone, he becomes super snuggly and transforms into a tiny, affectionate shadow who just wants to be near you, still on his terms, of course. Those rare, hard-earned cuddle moments are pure magic and absolutely worth the wait. He is silly, playful, and loves his toys. He is also free-roam trustworthy, and gets along well with other dogs. Tim is looking for someone who loves an underdog story and understands that progress comes in baby steps. He needs patience, consistency, and someone who celebrates the small wins like “he sat closer today” or “he didn’t run away this time.” In return, you get the honor of being Tim’s safe place and watching him slowly blossom into the sweet boy we know he can be. If you’re ready for a tiny dog with big feelings and even bigger charm, Tim is ready to meet you." Tim 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/tim/.

Story

Meet Buster! Buster is a 4 (almost 5) year old, 15 lbs, Chihuahua mix. This sweet, gentle boy is a total cuddlebug once he feels safe with you. He’s fully crate trained, potty trained, and walks well on a leash. Buster is smart, but also very shy—he can be skeptical of new people and needs someone who will go slow, respect his space, and let him build trust at his own pace. Once he warms up, his personality shines. With continued socialization and positive exposure to new people and experiences, he’ll continue to grow in confidence. He’s very chill, loves hanging out at home, and will happily entertain himself watching (or chasing!) squirrels in the yard. He’s great in the car, has no separation anxiety, and prefers quiet environments over big groups. If you’re looking for a calm, loving companion who will be your loyal shadow once he feels comfortable, Buster could be your perfect match. Buster seems to enjoy the company of similarly sized dogs, but he doesn’t require the company of one in his forever home. Buster is in foster in Mead, 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/buster You can apply for our wonderful dogs at https://www.milehighcanine.org/adopt/adoption-application/.

Story

General Information:Cookie is an approximately 4-year-old female Chihuahua who has been spayed, microchipped, and is current on her vaccinations. She arrived at the rescue facility at the end of August 2025 accompanied by one puppy, who has since been adopted. Origin and Arrival:Cookie was rescued from Southeast Colorado; we believe that she and her puppy were left outside without a lot of human interaction. Training and Behavior:She is kennel-trained and familiar with using a doggie door. Although she has experienced a few accidents inside the house, with consistent supervision, it is expected that she will become reliably housetrained. Social Compatibility:Cookie generally gets along well with most dogs but exhibits some bossiness and jealousy, especially when attention is given to other dogs. Therefore, careful management of interactions with other pets is advisable. Ideal Home Environment:It is recommended that Cookie be placed in a household with older children who are knowledgeable about dog behavior and language, ensuring a harmonious and understanding environment suitable for her needs. Please fill out an application on www.fureverdogdenver.com. If you would like more information or to meet her, please call or text 720 588-6809. ##2505063##
