Lymph nodes enlarge when the immune system is activated, usually by a disease process. However, if the lymph nodes are significantly enlarged-including the nodes inside the thorax and abdomen- then you should watch for symptoms including: In most cases, there are no outward symptoms that accompany your dog’s swollen lymph nodes, particularly if they are only mildly enlarged. If you’re petting your dog and feel a new or unusual bump in one of the areas listed above, it may be a swollen lymph node. Swollen lymph nodes can sometimes be detected by pet parents at home. Generally, the only palpable lymph nodes are the submandibular and popliteal in a healthy dog. Popliteal: Just behind the stifles (“knees”) of the rear legsĭuring a physical exam when your veterinarian looks like she is petting your dog, she is actually feeling for abnormalities in the lymph nodes, as well as unusual lumps or bumps.
Inguinal: On the underside of the dog where the rear legs meet the abdomen (groin) Pre-scapular: Under the submandibular lymph nodes at the front of the shouldersĪxillary: In the “armpit” of the dog, or where the front legs meet the chest Submandibular: Just under the jaw where it meets the neck

Lymph nodes that can be felt through the skin are known as “palpable” nodes. Your vet can tell the difference between swollen lymph nodes and regular lymph nodes by feeling the lymph nodes that are closer to the skin. Swollen lymph nodes are called lymphadenopathy or lymphadenomegaly. When your dog’s body is invaded by viruses or bacteria, or your dog has a disease that triggers an immune response, the lymph nodes become enlarged as they work to fight off the invader. Lymph nodes are small, bean-shaped organs that contain immune cells. The lymph system performs several important functions in your dog’s body, including transporting white blood cells, removing waste products from tissues and cells, and helping to produce disease-fighting antibodies. It includes lymph nodes and a network of lymph vessels called lymphatics that run alongside your dog’s regular blood vessels. The lymphatic system is part of your dog’s immune system.
