We have a food motivated dog that eats extremely quickly. He often gets sick. He would finish his bowl of food in less than 30 seconds. Now it takes some about 3 to 4 minutes to eat. He has not gotten sick once since we bought the the bowl over a month ago. I just ordered a 2nd bowl that we use on weekend trips. We just throw it in the dishwasher every few days. Very happy with this product.
