How can you identify a tick in a dog's ear? - briefly
Examine the dog’s ear closely, looking for a tiny, dark, oval or round parasite attached to the skin that may appear raised or engorged. A tick feels like a firm, movable bump and is often partially embedded in the ear canal or flap.
How can you identify a tick in a dog's ear? - in detail
Detecting a tick in a canine’s ear requires a systematic visual and tactile examination. Begin by restraining the dog safely, using a gentle hold or a leash to prevent sudden movement. Light the area with a flashlight or a penlight; the ear canal and outer folds become more visible under directed illumination.
Observe the ear surface for the following indicators:
- Small, dark specks resembling grains of sand, often lodged in the hair or skin folds.
- Slight swelling or redness surrounding a potential parasite.
- A raised, oval shape that may be partially embedded, with a smooth, leathery exterior.
- Presence of a tiny, clear “halo” or a pale area where the tick’s mouthparts have pierced the skin.
Feel the ear with gloved fingertips. A live tick feels firm and may move when pressed gently. A dead or engorged specimen feels softer and may appear balloon‑like. If a tick is attached, its head will be inserted into the skin, often appearing as a tiny black dot at the base of the body.
Confirm identification by inspecting the specimen’s anatomy:
- Body shape – elongated, oval, and dorsoventrally flattened.
- Scutum – a hard shield covering the back in adult females; absent or reduced in nymphs.
- Legs – eight short legs extending from the underside; visible when the tick is lifted.
- Mouthparts – visible as a pair of elongated structures (chelicerae) near the attachment point.
Use a fine‑toothed comb or a cotton swab to separate hair and expose hidden ticks. If a tick is suspected but not clearly visible, gently part the hair and examine the skin folds with a magnifying lens.
After removal, clean the ear with a mild antiseptic solution and monitor for signs of infection, such as persistent redness, discharge, or excessive scratching. Record the date and location of the find, as this information assists veterinarians in assessing disease risk.
