The Nelson Model 1200 Automatic Dog Waterer and Model 1400 Dog Feeding Pan system. Automatic Watering Bowls – These are generally used outside because they connect to a hose. However, if you have somewhere inside where you can connect the bowl to a hose, then this will work indoors as well. The downside to these bowls is that they tend to become dirty very quickly with food, dust, pet hair and other debris, just like traditional water bowls with standing water. This type of automatic water bowl works on the same principle as most toilet tanks do: a hose connects the bowl to a faucet, and a float and valve work to maintain the water level inside the bowl. If you go with this option and have larger dogs, be sure to get a sturdy bowl to prevent your pups from flipping the bowl over and creating a big mess.

Galvanized metal typically will not rust, but will turn an off grayish brown color depending on where it is located and how much sunlight it receives. Note that in double kennel situations, if one dog gets sick then the other will likely get sick as well from using the same watering source.
