fun behaviors to give dragons that aren't feline/canine based
cause as much as i love dragons purring and roaring i wish there was just more variety in how they would act
clacking their teeth together to show contentedness/happiness (budgies)
using tails as a defensive weapon in a whip like fashion (iguana)
twitching to express that they're not a threat to members of their species (hognose snake)
feeling calm when eyes are hooded/covered (birds of prey)
head bobbing as a threat display (anoles/bearded dragons)
flattening neck or sides to appear bigger (snakes/lizards)
mantling over food to protect it from hatchmates (birds of prey)
wiggling neck as a courting maneuver (budgies)
audibly grinding teeth as a warning (macaques)
maintained eye contact as a challenge (gorillas)
pounding wings against sides as a threat (gorillas)
slapping other dragons with their claws when their personal bubble is invaded (seals)
hoards used as a site to impress mates (birds of paradise)
snorting when undergoing heightened stress (horses)
making repeated loud noises with surroundings to establish territory (woodpeckers)
loud constant arguments with other dragons when roosting (bats)
building lairs that cause a domino effect of change in the land around them (beavers)
slapping their tails against the ground/water as a warning (beavers)
wiggling tail tip to attract prey (various animals)
wiggling tail tip as a warning (snakes)
plucking or scraping off scales as a sign of stress (parrots)
raising spines/frills as a response to danger and carrying on with their usual business as they believe they're protected (lionfish)
and im not saying canine and feline behaviors are wrong or bad to give a dragon (people wouldn't write dragons with those behaviors if they weren't fun in the first place!) but i feel for creatures that are mythological giant winged lizards that you can do more and get experimental with it. often the more unfamiliar behavior the more dragony the dragon feels
One of my personal favorite animal behaviours to give dragons is to have them hold their wings in a specific way that owls do to make themselves look Big and Scary, like so
