Swollen lymph nodes in dogs

Swollen lymph nodes in dogs is a symptom. The most common cause is inflammation of the limbs leading to swollen lymph nodes at the drainage site. In this case, the inflammation of the limbs must be eliminated and the lymph nodes will improve. If it is an older dog, lymphoma or tumor metastasis to the lymph nodes cannot be ruled out. It is recommended to take the dog to the hospital for a full body examination and symptomatic treatment.
