I'm looking forward to the replies too, Bertie will only drink out of the hose pipe attached to the outside tap. I have spent hours waiting for him to finish drinking in rain, snow, etc. in nightdress with the wind howling through it. The worst is first thing in the morning when it's icy and the water is frozen in the hose pipe he just won't budge until I get a large plastic bottle and tip it out for him.

We took him on a long car journey and we stopped to let him run about drink, etc. I produced the normal water in a bottle and started to pour it for him to drink. A man came up to me and offered me his dog's bowl and couldn't understand that Bertie wouldn't drink from it!!
By the way it has to be freezing cold water.
