Howdy all! I stumbled across this site while trying to get help finishing a trick, so hopefully you guys can give me some advise! I've been trying to teach a "snarl" command. Just teeth, no growl behind it. I was originally trying to get him to bark on command, but he very rarely barks, and when he does, never long enough to really proof the command. The most I've ever gotten him to do is raise his lip, which I finally decided to just forgo the barking and focus on getting a nice full-toothed "grin". I've got him showing them on command, but its very short. Observe: YouTube - Mulder- "Get Nasty" trick I try to only treat when he shows me gums. But how do I extend the command? Right now it looks like he's sneezing at me... how do I get him to hold the position into an actual snarl?
