What I have isn't the pot; it is more of a mustard bottle, a squeeze bottle. I could put different colors of dye in it to change it up for the dog. I could try a dark green or a purple. It is amazing how much water you have to pour into your head before any of it begins to come out. Of course mine was clogged shut and it didn't WANT to come out. I had to squeeze really hard. And you expect all sorts of creepy crawlies, but all you get is water. It must be microscopic shit.
