Once upon a time man chose to create dog breeds that mostly served a purpose, such as hunting, herding and protecting. These dogs worked for the farmer and the aristocrat.
Industrialization and the increase of dogs as companions had people altering the features of dogs purely for looks. Form no longer followed function.
From Atlas Obscura, "Dalmatians most likely originated in Croatia, with the first discernible depictions dating to the early 17th century. (“Dalmatia” is a coastal region of Croatia.) Early uses of the dog varied; it seems the first Dalmatians were all-purpose dogs, sometimes used for hunting, sometimes for guard dogs, sometimes for companions.
Their use as firehouse dogs emerged in the 19th century in the U.S., where it was discovered that Dalmatians have a natural affinity with horses. Fire engines at the time were horse-drawn, and Dalmatians proved very capable of trotting alongside and in front of the engines to clear a path and find the way to a fire."
Today our relationship with dogs continues its evolution. Now it seems we have more blended dogs than pure bred, and many more countries and societies seeing dogs as members of the family. We also have an incredible increase in the use of dogs as service animals.
I hope these trends continues. Sure, certain dog breeds will still be used primarily for singular jobs, but I like that we are seeing a wider embrace of all dogs.
If we continue to focus more on our unique relationship and bond with dogs and less on manipulating a dog's genetics, then we reflect a humaneness that shows our own positive evolution.
