Make sure the ceramic dog food bowl is certified for food use and is coated with a lead-free glaze.
If your dog food bowl is plastic, make sure it is BPA Free. PVC and phthalate free are a bonus. If you use a plastic dog bowl, occasionally check the color of your dog’s nose. If your dog’s nose starts to turn gray or brownish, and it used to be black, the plastic could be the culprit. Make sure to rotate different types of bowls to keep this from happening or stop using plastic bowls.
Silicone tends to be a safe choice for a dog bowl and is slip resistant too. The down side is if you have a dog that loves to chew, it can easily be chewed up.
If your dog is prone to seizures, avoid using aluminum-based dog food bowls. This material can make the seizures worse.
