Story
  When you get a call about a Scottish Terrier mix puppy needing a home, your ears perk right up — and honestly, ours perked up just like Baby Girl’s adorable little Scottie ears do now. This breed is rarely found in rescue, and this tiny dynamo is truly something special. Born on 10/31, she’s the daughter of a black Scottish Terrier dad and a mom said to be a Maltese, though you’ll be hard-pressed to find any Maltese influence in her looks. What you see is pure terrier confidence wrapped in a wiry little body. At just 8 pounds, she is compact, sturdy, and built like a tiny athlete — short legs, stocky frame, and strong as can be. We expect she’ll mature to around 15–18 pounds, but don’t let her size fool you. Baby Girl carries herself like she’s three times that weight. She fears nothing, especially not big dogs, and approaches life with bold curiosity and enthusiasm.   This girl is wicked smart. She’s already doing well with pee pads and understands going outside to potty. She’s learning leash walking — not her favorite activity yet — but with her intelligence and love of treats, she’ll master it in no time. She is very treat motivated, which makes training both fun and productive. In fact, she needs someone excited about channeling her bright little mind. Couch potatoes need not apply; this is a pup who wants to explore the neighborhood, meet people, and make you the most popular house on the block. At bedtime, her personality softens into pure sweetness. She loves sleeping in bed and will climb right up onto your pillow, settling in like your personal little “night hat.” She adores shaggy dog beds and has a hilarious habit of collecting unattended shoes and proudly storing them in her bed like trophies. When she plays with the Brussels Griffon in her foster home, she is dramatic and vocal — all noise and playful mouth, no biting — sounding like a 35-pound dog trapped in a tiny body. She’s fast, athletic, and would happily chase squirrels all day long, so early recall training will be important.   Her wiry coat may change in shading as she grows, but her confidence and spark are here to stay. Baby Girl is not just a puppy — she’s a personality, a conversation starter, and a whole lot of fun packed into a small, sturdy frame. If you’re ready for laughter, energy, and a smart little terrier spirit in your life, contact Critter Cavalry Rescue at ccrnewengland@gmail.com. She is ready to go and ready to claim her forever home.       PLEASE NOTE:  Our dogs are transported from Tennessee to meeting places in the states where we have posted.  Further information about us is given on our Adopt-A-Pet site.  The adoption fees vary and will be provided as well as noted on the application you receive.  Contact us at 615-661-5333 or ccrnewengland@gmail.comFebruary 19, 2026, 12:17 am
