> And yes, of course, our breeds were developed but they were developed, in most part, to suit a need or purpose and not as now to fill a bank account or just because they can.
Also most breeds evolved from existing local types that were good at particular things or suited a particular climate/terrain, not from scratch.
My won breed even though pretty old developed and was refined from Hunting Spitz, now that group of dogs are specific breeds, similar to what happened with Retrievers, Spaniels and Terriers etc.
So the various broadly similar use/type dogs were refined into specific types.
Nobody considered mating on purpose dogs of wildly differing type or traits.
Mate two terrier breeds you will have a crossbred terrier but a terrier nether the less, with terrier traits, ditto two retrievers or Spaniels, as they have broadly similar looks and traits. Mate a Buhund and Elkhound and you still have a Nordic Spitz, with broadly similar characteristics, but their strong points blurred by the mix, the result may or may nto make a good hunting dog or good herder, so not much point.
I suppose breeds evolved due to specialising for a purpose etc. Now that most breeds are primarily pets the specialisation is no longer needed as much and people forget what the purpose of establishing breeds was in the first place. Personally I think the breeds should be preserved as a reminder of what their purpose was, even if most are no longer required for it.
