So this guy told me the other day that to get rid of worms, you should feed your dog a penny every month. This sounded like the dumbest thing I have ever heard. He is not exactly the smartest guy I know, and makes lots of stupid comments that I know are false. He said that something in the copper will cause the worms to release themselves or something like that. Has any body heard of this? Is this some old school method of worming dogs? It sounds ridiculous, but I have been wrong before. Thanks for the replies.
