This dog feeder is great for a medium or large dog because it is raised higher to not strain their necks when eating. Now, this feeder came assembled and is super sturdy (I got white to go with my decor) with a great warranty. The bowls are easily removable to wash and dry that even my young kids help me. It is also waterproof, but if you have a dog that laps up lots of water at a time put a larger silicon mat under the feeder to save your floor.
