Even though these structures may seem very simple, they actually do provide two major benefits for your dog. A regular bowl is effective, sure, but it is important to consider how long the water sits in the bowl before your dog drinks it all. If your dog does not drink all the water in a short period of time, then that water can actually become contaminated. Still, water is at risk of experiencing an accumulation of certain microorganisms and other particles on the surface. This can result in hazards for your dog. When the water continues to move around in a fountain, it reduces the risk of these issues. Additionally, some people may find that their dog drinks more water when they use a fountain. This is because the consistent movement of the fountain actually helps to encourage your dog to drink more water. Thus, a fountain is also a great addition to a home where the dogs are not keen on drinking an adequate amount of water every day.
