I know that above Mo has written that using a rasied feeding bowl makes your dog more prone to Bloat however I would recommend knowing the breed of dog you have as to which bowl to use. I have Lurchers one of which is a Saluki X Greyhound who is 4 years old. I use a raised feeding bowl for him as it is recommended for more Greyhound as it is important to consider musculoskeletal problems, which are common for retired racers or workers who often have old injuries. Eating from raised dishes can reduce strain on the neck and back and lessen discomfort on arthritic joints, as well.
