I have a 5lb maltese whose breath reeked. This is what you need before the next sloppy kiss!

Oxifresh seems to be doing the trick. The treat types work pretty well, but can get expensive fast. I am so surprised it actually works!

Designed to curb odor and bacteria. It freshens you fur babies breath.

One cup of water with 1/4 teaspoon of additive and it's perfect. They have a 100oz petsafe fountain that gets cleaned weekly. It is definitely *noticeable* that their breath is significantly better after putting this into their water.

Diesl now has kidney disease and pancreatitis. Grizzly was diagnosed with kidney damage and died 1 week later. We have a 95 lb greyhound and a 65 lb ridgeback, and both lost their appetites with this in the water.
