About a month ago my smallest Dexter had yellow exudate running from her eyes. One eye was red. I asked the Vet and he said as long as she was keeping her eyes open and not squinting that there was no need for antibiotics. He thought she might have scratched the eye with something or it could be from the strong dry winds we were having. The eyes seemed to clear up except for the redness. Now I am noticing it tearing excessively again and she seems to have hives all on her neck and shoulders. Could it be allergies and what do you do for them? Also her umbilicus looks reddened and swollen. She is about a year old. Any thoughts?
