Story
Meet Boss — Fort Collins, CO 🐶🤎 Have you ever watched a shy dog slowly realize that humans can be kind? It is one of the most beautiful things to witness. Boss is a spunky, Approximately 1 year-old Rat Terrier with the most heart-melting eyes and the funniest little personality. He is approximately 10-12 lbs. He is part comedian, is learning to be cuddler, and full of potential. When Boss first arrived, he was very unsure of people. He likely never experienced gentle human touch before. But once he trusts you? He absolutely melts. He loves being rocked in a rocking chair, lightly pet, and even given little kisses on his head. He follows his foster mom everywhere and is learning how wonderful snuggly beds and couch blankets can be. He is still a bit skittish and will need someone patient who can go at his pace — but this sweet boy is SO worth it. Boss highlights: • Loves to run zoomies and laps in the yard Loves to chew on toys, sticks and pinecones • Big foodie (treat motivated!) • Hilarious, playful personality • Great with other dogs • Sleeps through the night in his kennel • Would thrive in a home with a yard and a playmate. • Not leash trained yet He is currently fostered in Fort Collins with a professional dog trainer who specializes in helping shy, unsocialized dogs gain confidence. The amazing part? She is offering a free training session to his adopter. This is not basic obedience — it is a confidence-building session designed to help you and Boss bond and help him transition successfully into your home. He would likely do well with: • A confident canine buddy (not required, but helpful!) • Older or calm children • Not sure about cats because the foster does not have any. Boss came from Oklahoma and deserves a fresh start full of patience, kindness, and safety. He is going to be incredibly loyal to his person — Rat Terriers are known for that. If you have a yard, a gentle heart, and room for a little shadow who will follow you everywhere… Boss may be your guy. Please consider giving this handsome boy his FurEver family 🤍 Apply today to meet Boss.

Story
&#226&#156&#168 Meet Chilly Male • Jack Russell Terrier / Beagle Mix • Born 12/09/2021 • 24 pounds Healthy • Vaccinated • Neutered Chilly is a lovable, happy boy with a wagging tail and a heart full of devotion. At four years old, he’s the perfect age — past the puppy chaos but still playful and full of life. With the curiosity of a Beagle and the charm of a Jack Russell, Chilly is a wonderful mix of fun, affection, and easygoing companionship. Personality Chilly is friendly, affectionate, and people-loving. He enjoys exploring on walks, following interesting scents, and then curling up nearby when it’s time to relax. He has a joyful spirit without being overwhelming and fits beautifully into a consistent routine. Chilly bonds strongly with his humans and thrives in a home where he’s treated as a true family member. Breed Info (Jack Russell Terrier / Beagle Mix) This mix typically brings together: Intelligence and problem-solving skills A strong nose and love of sniffing adventures Playful, curious energy balanced by affection Loyal, social personalities that enjoy companionship Chilly is well-suited for a home that enjoys daily walks, light playtime, and quality bonding moments. Owner Responsibilities Chilly’s future family should be prepared to: Provide daily exercise and enrichment Maintain structure, routines, and basic training Offer companionship, patience, and love Keep up with routine veterinary care Even though Chilly is healthy, adopters should take him to their own veterinarian as soon as possible after adoption. Things to Consider Before Adopting Confirm landlord or HOA approval Consider your schedule and ability to provide daily interaction Remember that terrier/hound mixes benefit from enrichment Adoption is a lifetime commitment, not a short-term decision The 3-3-3 Rule The first 3 days allow Chilly to decompress, the first 3 weeks help him learn your routine, and the first 3 months are when trust fully forms and he truly feels at home. &#226&#156&#168 Why Chilly Will Be a Great Addition Chilly brings happiness, loyalty, and warmth into every space he enters. He’s the kind of dog who makes ordinary days better just by being there. If you’re looking for a loving, well-balanced companion who’s ready to give his whole heart, Chilly is waiting for you.
