Bests & Worsts Reviews from Amazon

My malamute was about four months old when I decided to give this product a try. He loves to run around and do stinky things, which, consequently, would give him a bit of stinky breath. It wasn't unbearable, but there's nothing pleasant about it, either. When I got the water additive, we had recently started using a dog watering fountain that has about 2 gal capacity. Since he's still a young pup, I diluted the additive a bit more than what was instructed. It all went downhill from there. First, he started to drink from any source other than the main fountain with the additive. If there wasn't one, he would drink as little as possible from the fountain. I initially thought he might just need to take a bit to get used to the flavor, but now I wish I had taken that as a sign it was no good and stopped adding it right then and there. Second, he lost nearly all his appetite. This was shocking to me since growing mals should have nothing but a voracious appetite. Over a period of two weeks, he went from devouring everything in front of him to hardly touching his food. He would consume maybe a third of his needed intake by the end. Third, there was a weird gel buildup in the fountain any time I cleaned it. And there was a lot of it. Several other reviewers posted photos so you can see what I'm talking about. This was another red flag that I was I had taken more seriously and stopped right then and there. Fourth and Finally, my malamute started to vomit. A lot. At first I thought it might just be some puppy issue happening that day and to not worry, but it continued. This vomit was also not normal, either. Since he was hardly eating by this point, it was yellow, foamy, and slightly thicker than water. On the fourth day of it happening, he vomited three times within half an hour. I was very, very afraid for my dog at this point. These symptoms were a gradual build-up to the point where it ended in vomiting, so it had taken me a while to make the connection that this "dental health additive" was at the root of the issue. On that day where he was constantly vomiting, I thoroughly cleaned out the drinking fountain of any additive or the disgusting gel it was producing. I then hoped that he would get well on his own and I hadn't made a horrible mistake that required an emergency vet visit. After a few days, my mal thankfully did seem to go back to normal and has not had any nausea or vomiting since. He still seems uneasy about eating his food right away even after a few weeks of being free of that nasty stuff, but he does seem to be making a full turn-around. I can't say what for sure is at the cause of this whole thing, but after looking at the ingredients, it's likely that the sodium laureth sulfate is nothing but bad news. That stuff is meant to be in cosmetics and industrial cleaners, not in products designed for ingestion! SLES is known to cause nausea, vomiting, etc, along with other serious negative health effects if ingested over long terms, and is a chemical known to often be contaminated by 1,4 dioxane, which is a known CARCINOGEN. I cannot emphasize enough to NOT give this to your dog!!! If bad breath is a big enough concern, then look for a more expensive and better quality product rather than this cheap poison.
