I have a 10 month old shep pup that would lay down to eat, such an unnatural position. I also have a Boston Terrier so I got the small feeder for him. Since I had purchased these feeder in the past for my other huge dogs, I knew they would be perfect . I have been using the other feeders for over a year and they have done a wonderful job. They are sturdy and don't tip over. I live in a harsh winter area and I leave them on my deck and they still look brand new and they don't rust like some of the others I've had.
I highly recommend these for any size of your beloved 4 pawed dog critters::))
