My dogs lymph nodes in her neck started swelling about a month ago then i noticed the lymph nodes under her belly was swelling. Cpl of days ago I noticed that her back legs and feet was extremely swollen so I felt and looked for cuts or sores but found none. Did find that on both back legs her lymph nodes was hard and swollen. She is 14 years old and is a Shepard. Also has had a cough for the last month.

Swelling of the lymph nodes, especially when multiple lymph nodes around the body are swollen, is something that should be addressed by a veterinarian as soon as possible. Your veterinarian would most likely do a fine needle aspirate which means they would insert a small needle into the lymph nodes to draw out a sample. They would then look at this sample under a microscope. Widespread lymph node enlargement could be a type of cancer called lymphoma. It could also be an infection throughout the body. The cough could be related to infection or could result from enlarged lymph nodes in the chest. A chest x-ray may be necessary to find the cause of the cough.
