I had guard turkeys at onetime. The UPS driver told all my neighbors, "nevermind about the Great Danes, just look out for his turkeys!"![]()
I've heard some geese are good for that too!
A friend of mine in FL had a couple of guard donkeys. She said things could get past the dogs that the donkeys would immediately pick up on.
As for the back, the Princess just called me to come out and hear something stupid that Rudy Guiliani just said, and my back screamed as I got out of the computer chair.
