I was walking around my house about a month ago, and heard a strange growling noise. I looked down the hill about ten feet to a bare patch and a Juron was there but apparently did not see me. I had work gloves and a machete with me, but did not have any intention of killing the juron; I just tossed a glove near it. It attacked the glove - biting it! I tossed the other glove and it went after that too. Thinking this was odd, I moved toward the first glove and the juron came right toward me growling. I whacked it with the machete and that was the end.
Neighbors speculated that it might have had kits near and been protecting; or might have been rabid. Hard to know. But it definitely was aggressive. Other times when I have surprised one in the brush they have fled.
