Most Tymaeran dragons see other intelligent races (humans, elves, half-beasts etc) as something to be avoided, eaten or as pawns to be made use of. Which of the three usually depends on the dragon's size, age and their level (lack of) of respect for other species.
However, some work with other species as friends and allies. In some cases stolen eggs are hand-reared (sometimes over generations amongst shorter-lived peoples eg. the dragons owned by various heads of state in the human Empire), in other cases the dragon's respect and loyalty is somehow earned. Or the reasons might go entirely unknown. Either way, it's these people that make armour for dragons, since dragons aren't known for their metal working skills.
