Happy Pet Boingo Ball 4",
Verified Purchase(What is this?)
This review is from: Happy Pet Boingo Ball - Dog Toy, 4 inch, Various Colours (Misc.)
I bought this ball for my English Springer Spaniel who was blind from birth.
The Boingo Ball has a ball bearing inside which continues to make a noise for about 5 seconds after the ball has stopped, this enables him to find it even though he is blind!
The rubber which crosses the surrounding the central ball however is not dog proof and it should be supervised, otherwise you will just have only the plastic ball left after a few days.
