Ear mites in cats and dogs
Dark ear debris is a clue, not a diagnosis.
Ear mites can cause irritation and may spread between animals. Other ear problems can produce similar debris and scratching. A veterinary ear examination and sample check help identify the cause.
Ask whether animals in contact also need assessment. Avoid deep cleaning or putting unprescribed products into a painful ear.
