Ceramic and stainless steel dog bowls have pros and cons. But, overall, stainless steel is the safest choice.
Since stainless steel bowls are corrosion, rust, and scratch-resistant, they pose no health risk to pets or humans. The only real downside to the bowls is that they’re lightweight, making it possible for a dog to tip over or move. However, no-spill options with non-slip pads on the bottom of the bowl can take care of that problem.
Ceramic dog bowls, in contrast, are heavier and breakable. They also have potential health implications if they’re not appropriately glazed and therefore aren’t lead-free. And ceramic bowls are typically more expensive to replace than stainless steel.
