How does your character usually react to an insult

On the rare occasions that she actually understands when someone is insulting her, or making a joke at her expense, she seems to take it quite personally, and gets really mad. Whether or not you meant it doesnt matter, since in her eyes, you just said something mean about her. Also doesn't matter the degree of insult. An insult is an insult

She doesn't get physical or anything, but her mood will be noticeably ruined... until you give her a treat or something, then she'll probably just forget about it.
