I guess in a way this is a glitch.I put this under "Nintendogs Chiuahuah and Friends" because this is the only version I've tested it for.It may work for all versions though.Ok first teach your dog how to "Shake" then after teaching it,make it shake.While it's paw is in the air grab it and then shake it in front of its face(it may take a few tries).If succesful your dog will bark and if you are still petting its face you may take control of the dog causing you to be able to shake it around or whatever!*Warning!!*This glitch will make your dog mad at you causing you not to be able to play with it(This only lasts for like a minute though).Well have fun ^-^
