How many of you use these?

The theory behind these bottles is that the male dog when he approaches the tire to pee guardedly sees some reflective self movement in the bottle of water....and, then has doubts about raising his rear leg and thus possibly exposing his privates to something that might hurt a lot.

I've seen it plenty of times... i must assume that it works otherwise what would be the point of putting the water bottle out there every day after it's been pissed on (but then again normal logic sometimes does not apply in Thailand).... never tried it myself tho.

Did you end up getting the new S-class corky?
