The ball is not to get broken from a Beagle. He apparently also has an odor itself, which allows the dog to track him with the nose (throw in not einsehbares grounds). Unfortunately Amazon does not specify the size (diameter) of the ball. This risk of a wrong order (too big or too small for the dog). Even if it is only to 9 cents: is that the price in the online ad advertised with 9.99, but then increased in the order process (excluding shipping) on 10.08, is wrong.
