I've always thought a NZ Huntaway would be a better bet.
a farmer friend of mine has a huntaway and its the noisiest fecker ive ever heard you know when he is comeing up the road in his truck cause all you can hear is his bitch constant barking , even when she is at home in here kennel all she does is bark , i dont know if its a trait the huntaways have or just her , but after seeing and hearing her i wouldnt want a cross with it in just in case .
