What is this dog bowl called?

I know that there are pacer balls that help slow down the amount of time it takes for your dg to eat their food but I know that there are bowls specifically designed for this as well. I cannot find them on the internet probably because I do not know what they are called. My dog is eating her food within 30 seconds and is full of gas and hacking/coughing and I would like to slow her down to see if this helps. I have also tried putting her kibble in her Kong and that helps too. Thanks.
