I kind of miss the dog-people (in EverQuest they are portrayed as dog-ape-humanoids), but I've grown to love the dragon-blooded kobolds.
So I use both.
'Kobolds' are small hirsute primitive looking humanoids with some canine characteristics who can run on all fours for short distances, and they are skilled tunnelers and miners, and even, in rare cases, skilled craftsmen, being thought by some to be a degenerate dwarven offshoot race that make Derro look like Gray Elves by comparison. They combine traits of old myth, traits of EverQuest kobolds, traits of 1st edition kobolds and traits from Palladium RPG kobolds!
'Wyrmkin' are born from unfertilized dragon eggs, often a half-dozen to an egg (which, in the absence of male company, a she-dragon can lay several times a year), and end up fanatically serving their 'mother-goddess.' Many are abandoned, either deliberately (dragon wants a new home, but isn't going to ferry the little creeps to her new lair) or by mischance (dragon bit off something she couldn't chew and never came home...). They have weak characteristics reminiscent of their 'mother' (energy resistance equal to their HD, Green and Blacks can swim really well (not quite well enough to have a racial swim speed though!) and hold their breath like crocodiles, Whites can move unpenalized over snow and ice, etc.), and can breed true, with 'average' Wyrmkin being brownish scaled hybrids of other types, with no draconic traits at all (blended into normal Kobold stats, with no energy resistance or whatever).
