Query: Worth It!

Our yellow lab pup was inhaling her 1/4 cup of food three times a day - literally. Sometimes it would all come back up, whole! So, we needed to devise a way to slow her down. The square-shaped food dispenser toy would have been deafening on our hardwood floors so we opted for this "Mars" ball, as we call it. It's great! The pup learned to use the ball within seconds and it's much nicer on our floors. I would like to caution, however, as with the advice of other reviewers, that because the Mars ball is a softer material our pup WILL bite and chew it. Therefore she must ALWAYS be supervised (I don't mean you have to stare her down, but just keep an ear out). When she isn't getting food, it's up and away from her tough little jaws. All in all, worth every penny and we haven't had a regurgitation episode since.
