Which one should you choose?

These two sit at opposite ends of the toy-to-herding spectrum, and it shows in daily routine as much as temperament. The Sheltie wants real exercise and a job to do, channeling old herding instincts into agility, obedience, or just a long daily walk, while the Chihuahua is satisfied with short indoor bursts of play. The Sheltie is also the more biddable of the two by a wide margin, eager to please and quick to train, whereas the Chihuahua can be more independent and slower to warm to strangers. Both breeds are vocal and quick to alert-bark, though the Sheltie's coat needs considerably more brushing than the Chihuahua's near-zero-maintenance one. Families with kids will generally find the Sheltie the gentler, more tolerant companion. Choose the Sheltie if you want a trainable, active herder in a smaller package; choose the Chihuahua if your household is calm, low-key, and mostly indoors.
