Who can help me with the issue of foxes and coyotes roaming in my woods now and finding MIlo an interesting nosh possibility?

Yesterday around 5:00 PM, I heard some alarming cawing or barking noises that drew me to a window. Milo was strolling out of my woods followed by a fox (or small coyote). I shrieked from the open window and the predator ran. Milo seemed oblivious. The sound was I think that of a fox but the computer distorts things.

Should I keep him inside after 4 PM?
