My 170 lb Newfoundland just might be mellow enough to allow me to put a mask on him, but the device would be completely slobbered up in about 5 minutes.

That's a precious picture.

Actually, now that I think of it, the bag over the head might not be such a bad idea. In the Mastiff world, we refer to the slobber as "slingers" since a shake of the head can "sling" them great distances. Some mastiff home pages have articles on how to clean slingers off the ceiling.
