Breezy Breathe is a revolutionary product from Dr. Shiba. Maintaining your pet’s good oral hygiene will no longer be a struggle. Been giving this to our 3 furballs since its launch. And never had any unwanted sideffects so far. Just add 10ml to every 500ml in their water and that’s it! Just make sure to change the water and wash their dispenser/bowl regularly and add Breezy Breath. CHEERS!
