Before we get into the science of it all, Dr. Christman notes that owners who typically use stainless steel dishes for their pets should swap out the bowls prior to going outside. The combination of sun and steel will actually cook the water. Opt for a plastic or ceramic bowl instead.
Next, you'll want to draw a circle, square, heart, or whatever shape you want around the bowl with chalk. Doing so will prevent ants from sniffing their way to your dog's water bowl. It's essentially a barricade.
