While the power of some dogs is in their incredible cuteness, other dogs — though certainly no less adorable in many ways — have been bred to meet the demanding needs of the humans that they work with. LEGO 7 follows up his amazing LEGO hot dog food truck with a trio of pooches who do amazing and important work.

The massive St. Bernard serves in Alpine search-and-rescue (SAR) roles around the world, most famously in the Alps of Europe.

The border collie serves as a guide dog for disabled people, ensuring their comfort and safety.

Finally, this terrier proves that you can be incredibly adorable and still perform a role like search-and-rescue.
