The Drink Better pet bowl encourages dogs to drink at a slower, healthier rate, and make less mess while they¡¯re at it. Besides making a wet mess, dogs that drink too fast can experience digestive problems such as indigestion and vomiting, and light-haired dogs may experience staining of the muzzle (from chlorinated water). The Drink Better bowl uses a floating obstacle to control the flow of water, encouraging dogs to drink slower and take only as much as they need, without soaking their ears and muzzles or slopping water around the feeding area. Along with the EatBetter bowl, the Drink Better bowl encourages dogs to adopt a slower, healthier pace at mealtimes. The Drink Better bowl: Prevents dogs from drinking too fast.
