Nice design but it is a "no".
The Green Feeder has a nice design in the middle of the bowl. With different heights of the spikes slows down dogs more than other bowls.
With high doses of food, very low edges around the bowl allow food to spill easily on the floor which makes it very messy and wet/slimy when dogs clean the floor. Floor needs to be washed after each feeding.
Also, due to low edges, you can’t mix dry food with liquid (e.g. chicken broth). Big size of the bowl makes it not handy to wash it or store it.
