List of extinct dog breeds

I love that we bred a dog specifically to be a kitchen helper, but kitchen advancements meant they became irrelevant.

Argentine Polar Dog:

A long-haired breed developed by the Argentine Army to act as sled dogs in the country's Argentine Antarctic Program. The creation of the Antarctic Treaty System forced Argentina to remove all of the dogs from the continent, since they were an exotic animal. The army then ended their dog breeding program and the remaining dogs were moved to Patagonia where most of them succumbed to diseases, since living their entire lives in Antarctica away from other dogs had made them lose their natural immunity to the common diseases of dogs. |

R.I.P.

I am now sad

A whole lot of mastiffs.
