WHY DOES MY DOG SNIFF VISITORS` GROINS, AND HOW CAN I STOP HIM?

Dogs sniff human crotches for the same reason they sniff other dogs' backsides. SOme dogs, especially males, are more persistent at doing his than others. This is particularly true of those who are tall enough for their heads to be, unfortunately, at crotch height, as this is the first part of the human with which the dog comes into contact.

The best way of dealing with this natural, but unaceeptable, behaviour is to teach him to sit and stay when visitors call. He should wait until he's invited to greet them, and then sit by their side; stop him in his tracks if he makes a beeline for their nether regions by training him to respon to the command "No"
