In AZ, we had a goat and a guard dog. Both of them would run around the 5 acre yard checking for intruders, using the same path around the fence line. Contractors were more afraid of the goat then the dog, because of the horns. I truly believe the goat that it was a dog and acted accordingly.
I got head butted by a goat in the bohind one time going to interview a witness. Didn’t feel good. It came out of nowhere. Never saw it coming. I was wearing a jacket so it helped. The homeowner said it was her guard dog. I believed it...
In AZ, my children had a pet goat who ran and got in the car and rode with her head out the window when I drove them to school. Lol. Just like a dog. She always answered when called also.
