Most markers are simple pillow stones engraved with the name of the dog, his or her regisration number, date whelped and date died, and the owners. Most also include the dog's home state; one marker even includes a metal photocopy of the dog's registration papers (complete with photo). Still, most are simple pillow stones. The marker below is an exception.
One thing that surprised me was the geographic range of the dogs -- everywhere from Arkansas to Florida. I knew there were fox hunting enthusiasts in Texas; I didn't realize this particular dog cemetery was a national one.
