Here is GREAT NEWS for all owners of barky, lungy, naughty dogs: the penny shake can WORKS! This is apparently an old-fashioned remedy, but my goodness, it is the first thing I've tried that truly and instantly works. Get a small dry empty ginger ale can (7.5 oz). Fill with about 25 pennies. Seal shut with strong tape. Now, when your dog starts to bark or lunge, shake the can loudly and watch your little beast instantly become a little angel! I have been doing this for the past 3 days with my aggressive Jackhuahua, and wow! Hallelujah! He does NOT like the loud sound, and he falls right into line. This is the very first time with any technique that I've seen submissive body language from him, and he seems to retain the message. After a couple times of loud can shaking on an outing, any further misbehaviors stop with just a little rattle of warning. You've got to try this!View Thread
