Fragility changes the household gate
Chihuahua fit should start with handling reality, not just size or portability. Breed care notes highlight traumatic injury risk, dental disease, patellar luxation, heart questions, cold sensitivity, and small-body vulnerability. A good home can supervise children, furniture, stairs, doors, larger dogs, and rough play without treating the dog like a toy. The guidance should also avoid teacup-style framing and instead ask whether the owner can protect a tiny body while still providing training, enrichment, walks, and calm confidence building from the start.
