Without thinking about it, most of us likely top off our pet’s water bowl, rather than empty and refill it with fresh water. The problem with doing this is that bacteria has a chance to grow in the stagnant water, making it unhealthy for your beloved pet to drink. So, always empty your pet’s bowl, clean it, and then refill it with fresh water. Some people advocate for the continuous water flow bowls. This makes sure the water does not stagnate.
Another issue is the type of bowl you use. It is wise to use a metal bowl instead of plastic. Plastic bowls develop scratches and harmful bacteria may live in the scratches. Dogs and cats like to drink all through the day. It is really important that they have a reliable supply!
