Animal Water III Thank you for looking. I purchased this about 3 years ago and used it for about 3 months. The 3-hour waiting time for generation became a bit of a hassle, so I stopped using it. My dog can now brush his own teeth, so I've decided to sell it. Please consider this item after acknowledging that it has been used, the instruction manual is missing, and it will be shipped in a substitute box as the original box is not available.
