I ordered these Corona Lime bowls as I had been looking for some raised dishes for my 12 yr old dog. The ones in the pet stores were too heavy, too large & usually made of cheap looking glazed ceramic. The Platinum Pet bowls & stand are far better than I expected & my dog took to them right away. He is a large breed with arthritis in a number of areas, & no longer does he have to bend his neck & head down to the floor. The dishes are right at his level & allow him to eat & drink more easily & with less pain. They have a smooth surface & are very easy to clean (I use baking soda & hot water). The black grip rings around the edges also remove & replace very simply. The only concern might be that they are not very deep so do not hold too much, especially water. However, they are just right for us & a great purchase at the right price - my dog agrees & gives them 2 paws up!
