Aggressive Australlian Shepherd

by Sarah
(New york)

My dog roscoe is 2 years old. HE is very aggressive with strangers....Mostly men. He is very unpredictable. At times he won't care when I have friends over and other times he will. Like I said it's just guys mostly but we are very worried he will bite again.

He bit my boyfriend in the leg and ripped his pants while we were leaving the house one day.(My boyfriend does not live with us and is not frequently present in our household)He is very loving towards the ppl who live here. He does not like my Dads friend who comes over frequently threw out the week ever sense he was a puppy this man has be present and he still tries to bite him!

I really need help to try and stop him from this or my mom is gonna make me get rid of him. he also tries to chase bikers and things of the like. HELPPPPP!!!

Meaningful Corrections
by: Anonymous

Hi, Sarah:

Your problem is that your dog didn't get a motivational correction for exhibiting the aggressive behavior.

It will happen, again. Plan on it. Be prepared, and have a way to administer a motivational correction, when it happens-- so that he knows in no uncertain terms: This behavior will not be tolerated. I go into more detail on how to do this, in my book.

In addition: Start teaching him obedience training exercises, and make him do behaviors he doesn't want to do. (Ex. Down-stays around distractions and making him stay down). That builds dominance/leadership and makes your corrections more meaningful.
