| Can I teach my dog to snarl?
Kind of an odd thing, I know. People want their dogs to not be agressive, so how do you teach a dog this without sending it the wrong message? First off, I am not one of those hard headded people who just wants to teach their dog to fight, actually be mean, or anything of the sort, nor am I trying to impress my friends with this trick. I live in a rouch neighborhod in Cleveland and it's hrd to just walk to a friends house without being sexually harrassed or something along the sort at least once. I've even had a bike stolen out from under me.
I work at our local shelter as a volunteer in the summer, and I never had a dog. When Diego (my current dog) came in from the shelter, I jumped all over him, immediately in love. He's a medium sized pit mix, maybe with a Catahoula or Husky. He is a full bark brindle with pretty blue eyes. I had no intention of using him as protection from people around me at the time, nor had I even thought of it, but I've noticed that people seem to shy away from the girl with the pitbull now. Part of me feels insulted because I love my dog and know he is harmless, but another part of me feels wonderful to have a protector like Diego.
Anyways, back to the point. I walk my dog on the same route daily, and I'm pretty sure I was being watched. Someone else has seemed to figure out that Diego is harmless, and I was approached by a teen (older than me, or at least bigger) who actually tried to steal the [b]dog.[b] I do not want him to attack or bite anyone but I was wondering if there was a way to teach him to lift his lips and snarl, just to look mean, and not actually be mean?
I'm pretty good with training. I've self-trained him since I've had him. He knows all the basics (sit, stay, speak, lay, ect.) and a few other wierd ones like how to crawl across the floor on his stomach and how to simply "growl" on command. How can I get him to raise his lips and do the growl at the same time? |
