How would you go about teaching a dog to snarl on command? I've always wondered this. Especially a nice dog who you could never catch doing it to be able to make it into a trick with clicking. I've always thought this might be a good idea for security reasons such a stranger coming up to you while your walking your dog at night or something or someone threatening you in some way. You could tell the dog to snarl (using some kind of command) and the person would most likely get scared off. A snarl is very intimidating and so is a growl and could be used to that advantage. And the growl would probably be necessary at night because the person may not be able to see the dog snarling. How would you teach them to snarl? And what about teaching them to growl on command while snarling?
