They're bred for herding cattle (if you can believe it). They nip at the cows' heels to get them moving. I guess unlike sheep cattle are going to be hard pressed to see even a large dog as a predator and be herded so small, agile, and able to nip at their heels works better. I don't know if anyone uses them for that now, but that was their original purpose. Most short legged dogs are bred for being able to get down rabbit/badger/fix/whatever the specific breed is meant to be hunting holes, but in the case of corgis, it's cattle herding.

you are well within your right to not particularly like animals with short legs. but to me these dogs are the cutest damn things and make my heart melt. and i don't even find human babies cute. to each their own

I can see why you wouldn't - some short legged animals can look a bit out of proportion. They can have more back and hip problems than other breeds, due to the length of their back. Though you get so many different health issues with each breed anyway, as humankind has mucked these beautiful animals around so much. You stated your view nicely and it's a personal preference so it would be good if you weren't down-voted to excess. I'm not going to down vote you anyway!

You're totally right. But prepare for the negative flood.
