Miliary dermatitis is a type of skin reaction, usually caused by flea allergies. It’s characterised by areas of small, raised crusts on the skin. It’s usually seen along the back, tail and tummy. It’s also sometimes seen on the face and neck. 

Miliary dermatitis is common in cats but dogs don’t tend to show this skin reaction. Instead, they have areas of hair loss and red spots. Find out more about fleas and flea allergies here.
