Hands, feet or paws? Or something else?
They're called feet. You could also look at something like this. It always helps me when I'm stuck with labeling parts of a dragon. I hope it helps, and good luck!
feet, claws, talons if you want to add drama (my d&d dm insists on talons because its more menacing)
I'm writing a book where the main characters are dragons, and I use talons. I know that that's what they call it in WIngs of Fire, another book series about dragons, but I guess it's up to you.
