They say simple ideas are the best (though must admit being a gadget head I don’t normally agree with that philosophy) and this dog bowl designed to slow down eating is certainly simple.
I think the image will do better than words to describe how it works and if it prevents your dog getting stomach ache (and more importantly spreading food all over the floor) that can only be a good thing.
You can get the Brake-fast Dog Bowl for $14.99. [Found via Strange New Products thanks.]
