The thick walls on this crock are no joke—my dog has knocked it off the porch twice and it hasn't chipped yet. I also like that it's got recycled content and the Microban treatment, since his old plastic bowl started getting gross around the rim.
Wasn't expecting the thick walls to make such a difference, but this bowl doesn't slide across the floor when my dog gets excited at dinner. The Microban treatment is a nice bonus too, since it stays fresher between washes.
