I haven't posted in a while, but wanted a little advice.  My 1yr. GSP female needs some help with visitors to the house.  She doesn't bark or jump anymore, we fixed that with the "no" command pretty quickly. 

What she does do though is sniff everyone that comes into the house until I literally have to pull her off.  Leg and shoe sniffing doesn't bother me but when a friend comes over and she plants her sniffer in their crotch or rear it's a bit embarassing.

I make her sit or put her in a down away from the door when people enter and she doesn't have any problems with that.  I let them come through the door and walk in.  Once I release her though is when it starts.  "No" doesn't work on this like it did with barking/jumping.  Thoughts?

 Most people who come to my home expect my dog to say hello and we quickly arm them with a set of light weight aluminum cans (3) tied together and just the rattle of the cans works as a "NO"

Of course, she has been predisposed to know that the cans could be thrown at her when she was first training and would attempt to get on furniture or steal food. They are effective and don't hurt the dog. but you are not supposed to clunk them over the head, just a little rattle after the initial training. I read this in a gundog book from the early 60s by a guy by the name of Wolters.

My response was kind of personal as I wondered if others have used similar deterrents to unwanted behavior.

Enjoy
