Richard Demler, who does taxidermy in the upper peninsula of Michigan, was working on this whitetail buck (pictured above) and noticed it had upper canines. He also had this to say, “I did 2 (bucks) a couple years ago (with upper canines) and found out later they were killed less than a mile apart.”
These cases of deer with upper canines stem from pre-historic genetics. Even though the genetic link to various small Asian deer (aka Muntjacs), that have prolonged canine teeth that appear tusk-like and can grow upwards of 3 inches, has weakened, some deer still carry the gene.
If you are one of the lucky few who harvest a buck with upper canines, then be sure to hold onto it. Many hunters spend their entire lives trying to find this particular feature on a deer they harvest.
Below are some pictures of deer, today, with “fangs”:
