Because you know that cockers have skin problems like
seborrhea, you recommend a blood screen and a thyroid test to see if there is an underlying metabolic reason for this ear disease.
The mites cause a greasy dermatitis (
seborrhea oleosa) along the dorsum over the spine2 and have also been associated with intense facial pruritus (itch).4
Because it is caused by relatively few mites, folliculitis secondary to D. injai demodicosis may be subtle in presentation, making a diagnosis based on clinical observation more difficult.
