A "good" pet is one that always does what it's told. Even if its owner is incompetent and is telling it to do things that will not really help either one in the long run.
In a fantasy world, the Human race must be drastically similar to the White race in terms of power, prestige, etc. Humans are never allowed to be the "minority" in terms of power.
Or just the minority in terms of population.
Anywhere. Even monster infested hellholes should have more humans than anything else.
{... Dude, I read too fast and saw "monster" as "molester"...}
And if a non-human race is in some kind of power, it's up to the human race to de-throne them and ultimately make the kingdom/world a better place.
On the subject of dragons in particular, none of them are allowed to be intelligent or sentient. They are just automated fire-machines that like to torch anything that moves.
(Actually, I would argue that in most fantasy stories the humans
are treated as minorities. Everyone wants to read about pseudo-humans instead, like shapeshifters and elves. )
Remember, research is lame. Everything popular has plot holes (Citizen Kane!) and poor research (A Song of Ice and Fire), so you don't need to waste time doing that stuff either!
The best route is to put up a survey on DeviantArt to find out what most people like -- then just write about that stuff! Even better, ask them to fill out profiles so they can see their very own characters featured in the work!
