I have frequently seen dogs lapping at the faucets that are low to the ground such as at sink stations. I can only imagine what's doing that at night. I'm thinking a spray bottle of a very dilluted water and bleach solution sprayed on the faucet before use of the water thief is an idea.
Many national forest locations will have rustic campgrounds in the area with vault toilets and a hand pump. We have driven in and filled jugs many times when camping in areas without any facilities.

Hank what type of container are you looking at? Picture might help.
I BTW do not drink water from my trailers tanks - use if for dishes and showers etc only. I also start out with freezing water in milk jugs that I use as drinking water once its no longer frozen and refill those at locations I know for a fact the water is very safe and drinkable.
A lot of the hard plastic containers for carrying water at walmart and other stores are packaged for carrying dry. The nozzle is inverted and inside the container usually. You pull it out and unscrew it from the inside and then screw it into the outside when you want to use it. It's supposed to help you protect the spout when not in use but I find that people sometimes tend to over tighten when screwing and unscrewing them and then they crack. So be gentle.
