This morning a female German Shepherd surprised me with her intelligence. I carry around a Water Rover while walking my dog either around the streets of the Villages or at one of the various dog parks in or near the Villages. The Water Rover is a water bottle with a bowl attached which after you pull the plug at the top of the bottle fills the bowl with water. Here's a link to a picture of a Water Rover--

After my dog had got his drink and several other dogs had also took their turn near a shelter at Doggie Doo Run Run, a German Shepherd took hers but she could not get at some of the water in the bottle. She picked it up in her mouth, carried it to a hole, and put it down so that the angle of the bottle pushed the rest of the remaining water into the bowl.
Problem solved for this bright pooch.
