This is the second time this has happened in the last 2 months or so. I took her to the doctors the last time and she really didn’t know what the problem was either. I just gave her benedryl for a couple of days and eventually they went away. The itched her really bad the last time. This time she says they don’t itch at all. She doesn’t seem to be sick. I noticed them on her legs yesterday. I’ve been giving her benedryl since yesterday. It has spread to her arms and feet now. She wasn’t outside and hasn’t had anything new that I can think of. I am baffled. Would appreciate any input or advice.
