Belle had some hives, or bumps that looked like hives. I had just given her a bath and I think that I didn't get all the shampoo off her and she reacted to it. I'll be more careful next time (and have changed shampoos, too). The good thing about allergies is that once the source is gone, the reaction will usually clear up by itself (as long as it's not a severe one, of course). I took her to the vet and he gave me some of the surgical scrub that he uses for his hands before surgeries to bathe her with, and it cleared up the reaction in no time. From now on, per his suggestion, I'll be using a mild shampoo with few fragrances, etc (like baby shampoo). Just be sure to figure out what the cause of the reaction was for sure, if at all possible, and keep that away from Gemini in the future.
