@Cass yeah I thought that but that photo was a 12:15 and I’ve just checked under his arm and it’s pretty much disappeared now x
Could be hive or viral rash. If no temp, otherwise perfectly fine and rash disappears then should be nothing to worry about. If a viral rash might have/get cold like symptoms aswell. If hives could be from the current heat/sun or slight allergy to something. When my LB had the disappearing spots that looked like these I asked the doctor at my appointment and it was a viral rash and she said if otherwise fine then not to worry. It took almost 2 weeks from memory for his disappearing spots and cold to go completely
I’d say hives x
They look like bites 🤔
