Kids' Feeder/Baby Feeder: Products described as "Kids Dog Feeder" or "Kids Dog Steel Baby Feeder" are actually feeding bottles or containers for human babies. The "dog" part seems to be a design element (e.g., a "cute and colorful motif" of a dog) rather than a product for a dog. These feeders are made of stainless steel, have a handle, and are BPA-free, with a capacity of around 210-260 ml. 

Dog Feeder: There are also various products for dogs that are made of steel, but they are typically bowls or automatic dispensers with much larger capacities.
