This essay was inspired by many stories of owners feeling overwhelmed by their puppy’s behavior or exasperated in their attempts of correcting aggressive puppy behavior in their English Bull Terrier puppies and tired of their nipping/ biting and dominance issues.
First of all, please note that young dogs DO nip, chase feet, even growl and guard – these are all absolutely normal behaviors for a puppy.
An aggressive puppy usually is not “bad” by nature. The puppy is behaving exactly the same way as before, when it was still member of the litter among its siblings.
Now in your household the puppy needs to learn which behaviors are acceptable, and which are unacceptable. Aggressive puppy behavior needs to be addressed and corrected by training through the owner.
