This is a 100% safe and natural aid to remove that sometimes most unpleasant 'dog's breath' smell. The product contains a blend of beneficial micro-organisms and enzymes which help to remove the source of the bad odour in the pet's mouth and destroy the bacteria causing them. Small amounts, 5ml to 10ml, can be added to the pet's fresh drinking water each day for as long as required. Alternatively, and if your pet will allow it, you can lightly spray a diluted solution into their mouth as necessary. This product has also helped to reduce plaque build up on pet's teeth and improve the overall condition of teeth and gums.
