In most cases, your dog’s lifestyle is a better predictor of their susceptibility to certain diseases that cause enlarged lymph nodes. Toy breeds (such as Yorkies, Poodles, and Dachshunds) are very susceptible to dental disease, and often have enlarged submandibular lymph nodes when they have infected teeth and gums. Other breeds are prone to developing lymphosarcoma (cancer of the lymphatic system), including Golden retrievers, Boxers, Dobermans, Rottweilers, and others. However, some breeds are susceptible to diseases that will cause swollen lymph nodes. There aren’t specific breeds that are susceptible to swollen lymph nodes. Immune-mediated diseases (e.g., pemphigus) Reactive hyperplasia (e.g., active immune response)įungal infection (e.g., Coccidioidomycosis) Tick-borne diseases (e.g., Lyme disease, ehrlichiosis)īacterial infection (e.g., Yersinia pestis, which causes canine plague) Puppy “strangles” (i.e., juvenile cellulitis) For example, an infected toe could result in enlarged lymph nodes that drain that area.Ī systemic infection in which the whole body is affected will often cause many or all of the lymph nodes to be enlarged. If just one or two lymph nodes are enlarged, this often indicates a localized disease. 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 ARMPIT SKIN#

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. When you get your mammogram, let your doctor know when you had your vaccine shots and on which side (left or right arm).The lymphatic system is part of your dog’s immune system. This swelling normally goes away a few weeks after receiving the vaccine.īecause of the potential for swelling, consider waiting to schedule a mammogram for several weeks after receiving your COVID-19 vaccine. This causes the lymph nodes to swell and, possibly, to become noticeable to the touch. When you receive a vaccination, your lymph nodes are activated to produce white blood cells, which fight off infection. Lymph nodes are present throughout your body, but clusters of them are found in the armpits, neck and groin. Lymph nodes are small, bean-shaped glands that are part of your immune system. Temporary lymph node swelling after receiving the COVID-19 or flu vaccine is a normal, expected reaction. Is this normal? Why does this happen? Answer from radiologist Elizabeth Edney, MD:

I just got the flu vaccine and my armpit lymph nodes are swelled again. My lymph nodes in my armpit swelled after the COVID-19 vaccine.
