What does a tick bite look like on a dog immediately after the bite? - in detail
A fresh tick attachment on a canine presents as a small, raised area where the parasite’s mouthparts have penetrated the skin. The lesion is typically circular, measuring 2–5 mm in diameter, and may exhibit the following characteristics:
- A central puncture point where the tick’s hypostome is embedded; often appears as a tiny, dark pit.
- Surrounding erythema ranging from faint pink to bright red, depending on the dog’s skin pigmentation and individual inflammatory response.
- Mild swelling of the adjacent tissue; the edema is usually localized and does not extend far beyond the bite site.
- A translucent or slightly opaque halo that may develop as the host’s plasma exudes into the surrounding tissue.
- Occasionally, a thin layer of serous fluid or a faint crust forms if the bite has been disturbed or the dog has scratched the area.
The tick itself remains attached, visible as a dark, engorged arthropod partially concealed by the host’s fur. Its legs are often tucked against the body, and the abdomen may appear slightly distended as it begins to feed. The overall appearance is a combination of the parasite’s body and the localized skin reaction, which together constitute the immediate visual signs of a tick bite on a dog.
