I'm about to take ownership of a really nice 20 acre property that borders thousands of acres of hills, trees and mountains and was walking the property lines today with the current owner. He mentioned that coyotes come down to the property and he lost a dog last year. It was a small Dachshund but it got me thinking about my two Rottweilers and any other animals e.g. mini donkeys soon to be on the property. Am I going to have to provide armed security for my dogs during their late night bathroom excursions? Does anyone have any experience with packs if coyotes and the threat they pose to "common" pets and livestock?
