No! Hogs are just like other mammals and have what is called "determinate growth." That means that their long bones stop growing at maturity, just like yours did and just like your dog's did, deers do, etc. Now, the hog may continue to put on weigh, just like you might, but the hog won't actually "grow" their entire lives. In the case of long bones, you have the diaphysis (bone shaft) and epiphyses (ends of the long bones) and a cartilaginous gap between them called the metaphysis where the growth is occurring. When growth ceases, the metaphysis disappears and the epiphysis fuses to diaphysis.
Various poikilothermic taxa such as some fishes, amphibians, and reptiles have "indeterminate growth" and may continue to grow their entire lives, think alligators here, but their growth does slow down with age.
Awesome post!
