Indeed very large and complex topic. But this is just to see knee-jerk reactions of the majority, frist thought passing people brain. From there and they are satisfied or disappointed of where things are going.
Obvious answer- worse.
The development (or more accurately- evolution) of a type goes for better (in regards to the function that is being adapted to), but once a type is acknowledged as a breed, it's all downhill. Inherently breeds get fans and start getting bred simply because they're "breed x" and there's a market for them, and so whether they're show dogs or not, all breeds suffer the same basic problem, which is "evolving" to be a useless lump of a pet. All breeds, and even all unrecognised breeds that have made a name for themselves.
