This gentle mouthwash for dogs and cats uses alkaline ionized water. Easy for everyday care. Gentle on dogs and cats. Okay to add to drinking water, so it's great for pets who don't like being sprayed. Reduces stickiness and unpleasant odors, preventing oral discomfort. It penetrates the boundaries of dirt, and the attached dirt is surrounded by negative ions, which repel each other to remove the dirt. It spreads to every corner that a toothbrush can't reach and cleans. *All items are new. With virgin seal. [Ingredients] Alkaline reduced electrolytic water (water, mineral salt) [Free of] Alcohol (ethanol), synthetic chemical ingredients, sweeteners, coloring agents, preservatives [Frequency of use] Okay to use daily.
