Be the Alpha!

For any leg humpin', I would do what my trainer showed us to do.

Grab a fistful of hair and skin on the back of it's neck and drive your knuckles to the floor, while saying in very firm voice "NO!".. This should be done in a rather abrupt fashion. The goal is not the hurt the dog. They may yelp, ignore it.... They are just upset that they are being corrected..

Hold the dog down like that for a second or two, then let them go. When they get up, do not break eye contact with them, till they look away. This instills the fact you are the Alpha and not to be challenged.

This sounds rougher than it really is, and if you think about it, it's exactly what his doggie momma did to him when he was a pup and bit the nip too hard...

I have done this to many dogs.. All of them respect me when I walk in the room..

BTW he is a cute little bugger!
