Hot dogs are made from parts of: squirells, cows, pigs ect.
they arent made from squirrels...
Are hot dogs really made from pigs' snouts and unused meat scraps? Contrary to popular belief, hot dogs are not made from left-over meat laying around on the floors of meat-packing houses. Whether it is pork or beef that is stuffed into a hot dog, the meat trimmings are carefully selected just like the meat you buy in your grocer's coolers.
Most recipes for hot dogs combine together a tasty blend of favorite meats (pork, beef, chicken, or turkey), meat fat, a cereal filler which could be either bread crumbs, flour, or oatmeal, a little bit of egg white, and a mouth-watering array of herbs and seasonings including garlic, pepper, ground mustard, nutmeg, salt, and onion.
Once these ingredients are grinded together, the stuffing is squeezed into sausage casings. Many of the hot dogs sold in stores are enclosed in synthetic cellulose casings, but most home-made hot dogs are made out of natural animal intestines.
Following the stuffing process is the pre-cooking cycle in which the hot dog links are tossed into boiling water for approximately 15 minutes. Finally, the dogs are packaged, loaded on delivery trucks, and sent off to food markets.
Hot dogs are popular among Americans because they are easy to make, inexpensive, and delicious. Hot dogs can be prepared in a number of great ways--nuke-em, grill-em, sauté-em, roast-em, fry-em or boil-em.
