Query: Who says this actually works?

Read glowing reviews about this product so I bought 2! Well...my male chihuahua, in the beginning, didn't even to bother to sniff either one. Then weeks later, after I had wiped female urine from a friend's dog on them, he finally did lift his leg on one - ignored the other, and could care less.This might work for some folks' dogs - but the hype that convinced me to buy, for me, was just that- hype!
