Just maybe 50 yards (I'm really bad at guessing distances) from my horse stalls, we found this.
If you look closely you can see the paw prints all around. This is one BIG hole. Most definitely not rabbit, or pack rats.
Maybe bobcat?
It's not on our property - it's on a piece of property that I hope nobody ever builds on. 
Dozer (one of my horses) is rather concerned about it.
I'll let you know if I see any coyote pups soon!
