Stainless steel are suppost to be best, sturdy, long lasting & dish washer safe. Ceramic bowls are dish washer safe & can use boiling water to kill germs but they can crack & break & have micro cracks that can be a breeding ground for bacteria, Plastic bowls some dog & cats can be allergic to, dogs can chew their bowls, the plastic scratches & even with regular washing they can breed bacteria…I just human ceramic bowls for Patch, if I see any cracks I throw away.
