Dogs have lymph nodes throughout their body, many of which are not able to be seen or felt from the surface. Some of the commonly assessed lymph nodes include the prescapular (in front of the shoulder), inguinal (in the flank folds) and popliteal (behind the knee). However, there are lymph nodes along the intestines, between the lungs, along the inside of the backbone, etc.
Dogs have lymph nodes in various places all around their bodies. Specifically, they have lymph nodes in their throat, chest, under their arm, around the back of the flank, and at the top of the thigh.
Yes, dogs have lymph nodes--as do all, mammals. I'm not absolutely sure that most animals (reptiles and fish included), don't all have lymph nodes, but your question was about dogs. Being that the lymph nodes are necessary, as part of the infection fighting system of a mammal. Blood gets filtered through the lymph node, and some of the infectious stuff gets destroyed. Check out this page: http://www.peteducation.com/dict_alpha_listing.cfm?cls=0#L Scroll down to Lymph Node, and see the definition. Also, just as in humans, dogs can get cancer of the lymph node. I have no idea how common the disease is in dogs, you would need further research. For a site which discusses lymph nodes problems and dogs, see this site: http://www.vetinfo4dogs.com/dlymph.html
