Yeah, our two dogs don't seem to scare-off the fox(es), and they (the dogs) have somewhat gotten used to having fox smells around the yard. Odd, huh?
We've seen all of the above at our place, but no wolves, thankfully! Neither my wfe nor I would be scared to have them around, but I don't think the dogs would fare too well against them.
I have a somewhat similar history, but it also includes two '69 Mustangs, two Lund boats, and a bunch of High End audio gear.
