Choosing the Right Pet Food Bowl: Cats and small dogs prefer small bowls with low sides. Large dogs especially those with long ears or long silky hair on the ears such as members of the Hound group will prefer bowls with higher sides to keep their food in the bowl and keep their ears out of their food.
Older cats and dogs may benefit from a slightly raised bowl, such as a pedestal bowl or low table set. Raised bowls help to alleviate strain on the neck, hips and back. Additionally the raised position may also aid in the dog or cat's digestion.
You will want to avoid plastic bowls, as they scratch easily. Scratches in the surface of the bowl will quickly become havens for germs and bacteria.Stainless steel liners and bowls and ceramic dishes are easily sterilized and dishwasher safe. Replace ceramic bowls if the glaze becomes chipped or deeply crazed (small cracks in the glaze) as these areas will eventually harbor germs.
