What should be done for a lump after a tick bite on a dog? - in detail
A lump that develops after a tick has attached to a dog requires prompt assessment and appropriate intervention.
First, inspect the site. Remove any remaining tick parts with fine‑pointed tweezers, grasping close to the skin and pulling straight upward. Disinfect the area with a mild antiseptic solution such as chlorhexidine. Observe the swelling for size, color, and consistency; note any heat, pain, or discharge.
If the lump is small (<1 cm), firm, and non‑painful, continue to monitor for 24–48 hours. Record any changes in diameter or the emergence of additional symptoms (lethargy, fever, loss of appetite).
If the mass enlarges, becomes soft, fluctuates, or the dog shows systemic signs, seek veterinary care without delay. The veterinarian will typically:
- Perform a thorough physical examination to assess regional lymph nodes and overall health.
- Collect a sample for cytology or fine‑needle aspiration to differentiate inflammation, bacterial infection, or neoplastic tissue.
- Order blood work (complete blood count, serum chemistry) to detect tick‑borne pathogens such as Ehrlichia, Anaplasma, or Borrelia.
- Initiate empirical therapy based on findings, which may include:
- Broad‑spectrum antibiotics (e.g., doxycycline) for bacterial infection or suspected tick‑borne disease.
- Non‑steroidal anti‑inflammatory drugs to reduce pain and swelling.
- Surgical excision if the lesion is localized and unresponsive to medical treatment.
After treatment begins, follow the prescribed medication schedule and return for re‑evaluation as directed, usually within 7–10 days. Maintain a record of the lump’s dimensions and any changes.
Prevent future occurrences by applying a year‑round tick preventive product, regularly checking the dog’s coat after outdoor activity, and promptly removing ticks before attachment can last more than 24 hours.
