You are what you eat ( and drink ). Those who are health conscious are morecareful of what they eat, and of the beverages they consume. If you value the health of your prized pets and farm animals, you will also be careful of the quality of the water you give them to drink. That is whycanine specialty store -Good Dog Goods - on Circuit Avenue, in Oak Bluffs ( Martha’s Vineyard ) provides Chilmark Spring Water exclusively, to all the dogs that come to the store. Owner Kerry Scott, who is an expert on dog health, knows that our pure, untreated natural spring water, which is totally chemical free, is better for dogs’ ( and people’s ) health. Chemical free natural water is especially beneficial for old dogs, dogs with health problems, or animals under stress. It puts less strain on the system, and helps to flush out toxins. Tropical fish owners find that they can use our natural spring water right out of the bottle in their aquariums ( if it is the right temperature ). There is no need to “settle it”, or to treat it in any way, since it contains nothing that can harm fish. Chilmark Springwater comes from springs that flow into Mill Brook, where the Federally listed Brook Lamprey ( an endangered species ) has been sighted. This small fish can only survive in the most pristine quality water. Mill brook is near the North shore in Chilmark. Its headwaters remain clean and pure, due to a number of permanent conservation measures put in place years ago.
