Sales of bottled water for dogs (with prices similar to that for people) are growing, according to a March Wall Street Journal report, spurred not only by sudden concern about vitamin deficiency but apparent certainty among some owners that their pets find tap water disagreeable and thus are dangerously at risk of dehydration. Of course, veterinarians cited by the Journal are puzzled by this recent rejection of municipal water and suggest it might be a food-bowl-smell problem rather than a new dog generation’s preference for fine beverages. Also, some vets believe dogs prefer the cooler temperature of, say, toilet-bowl water to that of food-bowl water.
