Story
&#226&#156&#168 BUSTER — Male, Chihuahua Mix, DOB 12/05/2024, Weight 10 pounds Meet Buster Buster is a tiny guy with a HUGE heart. The moment he looks up at you with those big, soulful eyes, you feel it — this little boy is pure love. He has that special Chihuahua charm: a mix of sweetness, silliness, and unshakeable loyalty that makes you fall for him instantly. Buster is the kind of dog who wants nothing more than to be someone’s shadow, someone’s comfort, someone’s little piece of joy in a busy world. Personality Buster adores his people. He’s playful in a gentle, charming way and blossoms with affection and reassurance. He loves being held, loves snuggling, loves being included, and has the cutest little prance when he’s excited. He’s bright, curious, and always ready for a warm lap or a soft blanket. He may be small, but he loves big — and he wants a family who loves just as big in return. Breed Info Chihuahuas are known for their loyalty, big personalities, and deep bonds with their humans. They thrive on closeness, routine, and gentle guidance. They may be tiny, but they make some of the most devoted companions you’ll ever meet. Owner Responsibilities Buster needs patience, routine, soft guidance, and someone who understands that small dogs have big feelings. He will need regular vet care, training, gentle handling, and a home that keeps him safe and included. Things to Consider – Make sure your landlord allows pets – Consider your schedule — Buster thrives on closeness and companionship – Tiny dogs can be sensitive, so safe handling is important – Are you prepared for lifelong care, including food, vet visits, preventatives & love? – Think about your future — moves, travel, lifestyle changes all affect him – Puppies and young dogs need time, structure, and patience The 3-3-3 Rule Give him 3 days to decompress, 3 weeks to learn your rhythms, and 3 months to truly blossom. He will slowly show you every sweet, silly, loving part of himself. Why Buster Will Be a Great Addition If you’re looking for a dog who will adore you with his whole heart, Buster is your boy. He brings warmth, sweetness, and companionship into every room he enters. He’s the dog who curls into you when you’re tired, celebrates when you’re happy, and stands by you like your tiny, loyal best friend. Bringing Buster home means bringing home love — simple, pure, and constant.
