How is a foreign body diagnosed?
Diagnosis is based on a thorough physical examination, possibly with the pet under sedation or anesthesia. A biopsy may be needed if a granuloma has formed to rule out a cancerous growth.
How are foreign bodies in my pet treated?
Treatment is directed at removing the foreign body and addressing underlying infection. If an inflammatory granuloma has formed, surgical removal may be needed.
