Hi and thanks for your post on Petco Pet Education Center, formerly Petcoach. Oh dear, this sounds like Bella has hives indicating an allergic reactions to something she was exposed to. Please take her into a veterinarian right away for treatment. She will need antihistamines and a steroid. Whatever she was exposed to needs to be identified so she does not have a reaction like this again. Best of luck!
