Stainless steel remains the most popular choice for pet dishes for a number of good reasons. Its nearly impervious stainless steel surface will not absorb smells, does not stain, and is easy to clean and disinfect. Most pets won’t pick up or try to chew on stainless steel so your bowls continue to look shiny, clean, and new. They’re also heavier so they’re less likely to tip over. Dishwasher safe.
