We absolutely love these design of these auto water bowls for our dogs.  So much so that I was excited to nab one for 8 bucks to use outside for our pups now that we moved into a house.  So for a giggle the left one is what I ordered and the right one is what we already have.  Now in all fairness this is my mistake but I hope you get a laugh out of it.  I mean that auto watering dish is for a hummingbird not a dog!   Check your proper size when ordering.
