Needs some design adjustment
I got this for my Rottweiler. It was much bigger than I expected (even for him!) but I like the shape, material and it does slow down his eating HOWEVER I agree completely with some previous reviews. It is very difficult to clean well (I don't have a dish washer) and it tips over far too easily (its unexpected size means I can't even find an oven dish big enough to put it in). Feedback to manufacturer: Put it in a bowl shaped type dish with a heavy bottom AND sell it with a free cleaning brush!
