Full trait-by-trait breakdown

Which one should you choose?

Both breeds descend from herding stock and rank among the most trainable dogs in existence, but the Sheltie carries that intelligence in a gentler, more overtly biddable package, while the Border Collie's drive borders on obsessive and needs a genuine job or serious daily exercise to stay balanced. The Sheltie is content with a solid walk and some structured play; the Collie needs considerably more — vigorous, sustained activity and mental challenges, or it will invent its own outlets, often by fixating on movement. The Sheltie also tends to be warmer and more immediately welcoming with kids and other pets, while the Collie's intensity calls for more careful management. Both are vocal, alert dogs, though the Sheltie edges ahead in tendency to bark. Choose the Sheltie for a smaller, gentler herder that still loves a job; choose the Border Collie for the single most driven working mind in the herding group.
