Indeed they do!! It's a large (2'-3'

gland in the center of the back directly over the hips. You can't miss it!!!Smells a great deal like a skunk, and if not removed immediately the meat will not be fit to eat, if you are inclined to do so. If you plan to eat Javalina (collared peccary), try to get a young female. When cleaning, try to keep any hair from touching the meat. That will taint it also. Properly dressed and prepared, young Javelinas are not bad, assuming they have not been on a steady diet of prickly pear.
