Most irritating blood sucking parasites found in the external ear canal of pets called Otodectes cynotis.

Signs and symptoms:

It causes severe otic discharge and pruritus. Usually “coffee color exudate” oozes out of external ear canal which may be off smell. Sometimes crusting or scaling may be present on the ear pinna and neck. Excoriation or scaling may lead to intense pruritus. Due to intense scratching, sometimes pyotraumatic wound may occur inside or around the ear.


Ear mites when infest the skin then they bite and release some chemicals which trigger animal’s immune system. Due to this trigger, some neurotransmitters released at neuronal junction which causes intense itching due to release of acetylecholine at the neuronal junction. This intense itching may cause pyotraumatic wound due to rupter of sublined capillaries.

How to diagnose ear mites:

1. Ear Swab : Ear swab cane be used for identification of ear mites. For identification, we need to put ear swab on mineral oil. It is a useful method of identification of ear mites.

2. Skin scrapings: Skin scraps can be taken for identification of ear mites.

How to treat ear mite infestation?

Affected Ears should be thoroughly cleaned with a commercial ear cleaner. Otic parasiticides should be used for 7–10 days to eradicate mites and eggs. Effective topical commercial products contain pyrethrins, thiabendazole, ivermectin, amitraz and milbemycin. To prevent reinfestation from eggs treat during alternative weeks for two to three treatment cycles is recommended. Selamectin spot on solution can be used topically and can be repeated at 2 weeks. Imidacloprid/moxidectin (Advantage Multi/Advocate) can be used to treat ear mite infestation. Ivermectin 200–300 kg PO (three treatments) or SC (two treatments) at 14-day intervals can be used which has good results on ear mite infestion in pets. These parasiticidal drugs should be used within appropriate dosage as these drugs may cause severe side effects and toxic reactions in the body like nausea, lethargy, neurological changes like seizures. Erythmia may occur as a result of skin reaction as suggested by Pet Prime ( best pet clinic io Gurgaon) .

In severe toxic reaction of these parasiticidal drugs, death may occur due to severe affection of respiratory, circulatory and nervous system. Generally cats less than 6 months of age shows abrupt side effects for ivermectin and moxidecin. Topical antiparasiticidal drugs should not be used for cats due to their sensitive skin and adverse reaction. Traumatic wound should be treated accordingly. Antibiotics can be given to avoid secondary bacterial infection as suggested by Pet Prime (dog and cat clinic in Gurgaon).
