Stainless steel is the material least likely to rust over time for dog bowls due to its composition and protective qualities. Stainless steel is an alloy that contains chromium, which forms a thin layer of chromium oxide on the surface. This layer acts as a barrier to moisture and oxygen, preventing corrosion and rust even in humid or wet conditions, which are common around dog bowls.

In comparison, ceramic, plastic, and glass can have various issues that make them less suitable in terms of rust or deterioration. Ceramic can chip or crack, and while it doesn't rust, it can become damaged and harbor bacteria if not properly cared for. Plastic is resistant to rust as well but can degrade over time due to exposure to sunlight and heat, leading to brittleness or discoloration. Glass is also non-corrosive but is fragile and can easily break or shatter, which poses safety risks for pets.

Therefore, stainless steel stands out as the most durable and rust-resistant material for dog bowls, ensuring long-term use.
