Smooth-Coat Chihuahua · Long-Coat Chihuahua
Tiny bodyguard with a giant personality for small homes
The smallest dog in the world — fits any apartment and travels anywhere. Fiercely loyal to its person, but loud, fragile, and chilly: needs a jacket in winter and gentle handling, not rough kids.

Curated starter supplies researched for this companion's specific anatomy and needs
With their tiny body mass and rapid heat loss, Chihuahuas shiver readily in indoor air conditioning or mild drafts and require lightweight daily fleece layers.
Chihuahuas suffer from severe tooth crowding in their minute jaws, leading to rapid tartar buildup and early tooth loss without daily enzymatic plaque breakdown.
Chihuahuas are highly susceptible to tracheal collapse; neck collars must never take leash tension, making an ultra-soft step-in chest harness non-negotiable.
