H2O is a medium to large dog fountain with a 200 fl. oz (6.3 liter) capacity. Given a choice, your dog will prefer running water because his instincts tell him that running water is clean water!
Ensure drinking water throughout the day and especially if your water is hard or ferrous.
H2O has the features that make a quality fountain and includes as a bonus dental care tablets that contribute to better oral hygiene for your dog. The tablet dissolves slowly in water and releases potassium sorbate and sodium benzoate substances that help prevent the formation of dental plaque and tartar deposits for healthier gums and to combat bad breath.
