I have a Jack Russell, and he wants to/does kill ANY little(or big) furry animal he can.
The chickens drive him nuts, and I know hes gonna try to get them once they hit the outdoor run.
I use a shock collar on my JRT, because there is no other way.
I use the lowest setting, and he already knows that once the collar is on, he needs to behave . . .
It didnt take him long to figure out going near certain things would cause him to get shocked, and if the collar is on hes on his best behavior- rarely do I need to hit the button these days.
But if the collar is off, watch out small furry animals.
My mutt(1/2 lab and 1/2 cattledog) is not so simple . . .
She is a sweetheart and I dont think she would purposely hurt the chickens, but I can see her struggling with her instincts . . .
She cant decide whether she wants to herd the chickens, or bring them back to me.
But, I am not really worried about her just attacking them, she knows they are mine.
But I do worry that she would be too rough with the young chicks that I have right now.
She has no finesse.
I go to great lengths to keep the dogs away from the chickens, my coops/runs are strong and well-built using multiple layers of heavy screens.
