I purchased this diner for my 60 lb Siberian.  My 7 lb Pomerania was finding ways to stretch into the 13 in feeder I previously had and was having a field day eating her sisters food.   I was worried that an 18" platform would be too high for the Sibe but it wasn't--it was the perfect height.  Problem solved!   This Diner is sturdy, well made and would compliment any decor.  I highly recommend it!
