What is the best breed of dog for protection and on a farm?

I am assuming you are talking about an Australian Blue (or Red) Heeler.
I didn't know anything about heelers at the time and I thought that was normal. I learned later that it was not. I was actually afraid to walk past that dog's kennel for fear it would get out! I don't think I have ever been that afraid of a dog before.

A family member had a pit bull that scared me.

I have been chased by pit bulls, but never really afraid of them.
I had one that chased me on a bike trail once. I saw him chasing a girl that was on foot and I rode my bike between them and made him chase me instead. Once I got some distance from him he broke off the chase and I stopped and called 911. On the way back I was ready for him. I picked up a big stick and whacked him over the head as hard as I could which made him break off the chase.

That girl was lucky you came along.
