Story

Meet Oscar! Oscar is a 2 year old, 13 lbs, super playful guy that loves his canine foster siblings. He has a feisty play style and will be best suited in a home with another playful dog. He may be small in size, but he’s big in personality, as some small dogs can be. He brings spunk, sass, and constant entertainment to his foster home. Despite his love for fun, he’s also up for a good lap snuggle. He is crate trained (although he likes to sing if he knows you’re home) and he’s working on house training. Oscar is being fostered 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/oscar/.

Story

Clay (M) and Thumper (F) are a bonded pair of PomChi’s looking for a home. Clay is 8 and Thumper is 6 years old. They are both under 10 lbs with Clay at 8 lbs and Thumper at 7 lbs. These two are so sweet and cuddly. Wherever one goes the other is sure to follow. Their favorite spot is basking in the sun, working on their tans. Both seem to do well with their house training when they have outdoor access (a doggie door propped open) and also use puppy pads. Thumper isn’t fond of leash walking so we are seeking a home with a securely fenced in yard. These two would be fine as the only dogs in the home or joining an existing pack. A busy home likely not their jam. Clay & Thumper are 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/clay-thumper/.

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 Broomfield, 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 dog 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. ##2505063##

Story

Rudy and His Mama - Rescue Intake Report Introduction Rudy and his mama were brought to the Rescue from a southeastern town, where they were not being properly cared for. Both Rudy and his mother were quite feral when they first arrived at the rescue. Mama's Background Mama is a 2-year-old female dog. She has been spayed and microchipped and is up-to-date on her vaccinations. When Mama first arrived, she and her baby were very feral and closed off. However, since being in the Rescue's care, they have become more open and affectionate, seeking attention and love. Mama's Behavior and Training Mama learned to use the doggy door very quickly. She is accustomed to being crated at night. Mama is not yet fully housetrained, but she should pick up on it quickly with some additional training and time. Mama generally does well interacting with most dogs. Recommendations Mama would do best in a home that can provide her with patience, care, and continued training to help her adjust and become better socialized. Her new family should be prepared to work on housetraining with her. She can be very jealous of other animals getting attention; she would be a great only dog or a dog that is not a lap dog. She has done good with kids that are not quick movers. She would do best with older kids. With the right environment and support, Mama has great potential to become a loving, well-adjusted companion. Overall, Mama is a young dog who has made significant progress since being at the rescue, and with the right home and care, she has a bright future ahead of her. ##2422213##
