if it has no temperature, it pretty much sounds like eczema, hun!
Juleika also gets dots and they are raised! (this is why I always thought it's heat rash, but the dermatologist in hospital confirmed that eczema can look like this!)
as well the dog or/and the hot wheater can provoke eczema!
if Juleika gets to hot, it just pops out!
good luck, hun
