Query: My Dog Would Not Drink His Water With This In It

Too bad, he is a 2 year old Italian Greyhound Miniature Pinscher mix with beautiful teeth that I would like to keep nice. This additive had no smell or taste that I could detect, but he would not drink the water with this added, even if I added the smallest amount. This was with the water filtered through a Pur water filter. Oh well, he still has his CET chews and toothpaste which he likes.
