I have a 18 month old male Bull Mastiff who has a really stubborn disposition.
I have had rottweilers and dealt with a stubborn breed before, but this dog - although very sweet,
had a stubborn streak.
I have only had to use an instant shock twice - but always sounded the audible when i take him
out in the fields.
Now he responds to just the audible sound and comes back to me immediately.
What a fantastic product!
