A Mystery On Quail Way

For the past few months we have been trying to figure out a mystery that is happening around the farm.  Not on the farm but around it.  It started out with our neighbors dog, Scamper, having a couple of puncture wounds on her hind legs.  We know we have coyotes on the property and we know that there are a few.  So we assumed that a coyote got her.  Shadow does not like to go out at night and most nights refuses to go out after dark.  Now we think we know why; there is something besides coyotes out there.  A couple of weeks ago our neighbor's son's dog was attacked and the attack was heard.  To scare off whatever was attacking Reggie's dog he had to shoot a gun in the air and then found his dog pretty bad chewed up with a large hole in it's side and the intestines hanging out.  He rushed the dog to the vet where they operated on it for over three hours.  The dog is good and healing.  Then just last week Dingo, our neighbor's other dog was found with puncture wounds.  They were treated and she will be okay.  The final hint to the mystery is our neighbor's cat was found with it's head ripped off of it.  So, our question is what is wondering around Quail Way and why is it attacking our pets?  Is it a Bobcat, a cougar, a mountain lion or a bear?  Either way, we are watching our pets a little more closely and ourselves too.  Check back and see if we ever do find out what is lurking on Quail Way and how to get rid of it.
