afraid to drink from bowl

Hi Tom,
 
Is her water dish metal by any chance and she has tags on that are hitting the bowl when she drinks?
 
I had that problem with my 21yr old. So I put her in a harness with her tags on her back. The sound of the tags hitting the metal bowl or plastic bowl would startle her since she was going deaf.

Can you better describe the type of bowl she drinks from.

It's a stainless bowl, the same one she has used for years.  She doesn't seem to want to get near it.
 
She also has the same bowl for her food.  I had been feeding her on  paper plate while sher was recovering.  Last night I put her food back in the stainless bowl to see if she was afraid of that one too.  She didn't seem to mind that.  She ate as much out of the bowl as she did off the plate.
 
Thanks for the comments!

One day, I came home, started to feed the dogs, and a TV announcement that our local water had been tainted by the addition of too much of one type of chemical came on.  We were directed not to use it.  I had just put Sioux's food down for her (moistened with the contaminated water) and rushed to her room to find that she had not touched much of the food.  I can only  think that she noticed a difference in the odor of the water.  Has anything like that happened where you are? 
Other than that, I can only surmise that something about drinking bothered and she associates it with the bowl, instead of with the water.  Try changing to a ceramic bowl and see if it makes a difference.

My guess is that the still water in a bowl may be hard to see without getting one's nose IN it --
 
a) I would try bottled water rather than tap water.
b) I would try a tall glass bowl (like a big Anchor Hocking 1 1/2 qt bowl -- so it is higher  and may be easier to smell or hear where the surface is -- Old dog Vestibular disease can leave them with some fears because the dizziness is so pronounced.  My old Foxy got really persnickety about bowls and such -- he HAD to have his bowls elevatored so he didn't have to strain his neck.
c) try putting a dish under a drip spout -- like they sell water drip spouts for outdoor spigots --- he may want to HEAR the water dripping in the bowl -- in that case how about putting his bowl in the shower inside and let water drip for him -- or attach a hose to a faucet inside and literally let water drip into a bucket for him.

I had a cat that would not drink standing water.  He would only drink from the sink tap or the bathtub.  Now they have water fountain type things that are made for dogs.  Maybe that would help. 

When sled dogs stop to take a rest often they would rather eat snow than drink water.  But its not sufficient to rehydrate them so mushers sometimes flavour the water with a little broth to train them to drink on command.  Maybe if you make the water more appealing... that is if it is not contaminated like Anne suggested.  Try bottled water first to see if it is the bowl.
