I already had a bunch of ideas, but I didn't want to limit myself to one mind. two are better than one :) Here is what I was originally thinking. The only reason I didn't want to post it, was to hear other people ideas without being pigeon holed.
Why wouldn't dragons develop in similar ways to humans, I.e. cloths, belts, bags. Posessions, houses?
Naturally they have certain advantages, and don't need certain weapons like spears, and likely, nothing is threatening to an adult dragon, or any dragon past a year of age.
But they might have wars, or histories of wars.
I'm picturing a dragon eggs might take a while, and instead of being raised by a single or two parents, they are raised by the community, as a group effort to teach and protect them. So dragon eggs remain in a nursery with other eggs until they hatch, where they are raised in an academy, which is kind of like a boarding school where other dragons of all types come in to help teach and pass on wisdom. Once they are old enough, and have passed at least one test, (different tests for different characteristics, like battle, magic, medical, farming, etc..) they are released to live in the wild for a year. where they will try to employ their knowledge.
On their return, they have various jobs. At this point, they will seek masters. Dragons will use multiple masters, but in different trades. Their culture believes you do best when you spread out your knowledge further, and learn to apply helpful things from multiple industries to improve them.
Some are farmers, raising sheep, cows and bears for food. Others run restaurants. Other ones are minors, raising up stone for buildings.
By human standards, dragons live in huge buildings. carved stone of intricate work. Much of which is done by hand, but dragons still use tools, and have use of metal smiths and wood workers to produce them.
There is more than one type of dragon, but they tend to live separately. larger dragons can sometimes miss the smaller ones and step on them. it just doesn't work out.
the smaller ones are a little more like man, and do work for the larger dragons, and vice versa. The larger dragons are often the large structure builders, and smaller dragons often do the detail work.
Older dragons are revered as wise in their culture, and are the most sought after masters, but will often set strong standards for who they will teach.
