I bought one for each of them...I know they're made especially for flat face breeds but I'm not sure its all that much different form a regular one...they still wolf down their food in about 45 secs! I'm sorry I don't have a code..I bought mine about 6 months ago..from what I remember they weren't cheap...around 40?
I just bought one about a month ago. I'm a fan! It almost contains Harleigh's mess (she doesn't always eat from the correct angle). When she eats the food goes up the little ramp and back onto her tongue when she flicks it. (Best description I can think of at the moment). The bowl stays in one place, which is a huge plus to me! I really don't have any negatives to say about the bowl.
