'We have conducted scientific suction tests on the Beco Balls which analyses the size of the aperture, volume of the vacuum and importantly the material elastic strength. The higher the elastic strength of the material, the higher the suction force will be. The larger the vacuum volume, the larger the force. The smaller the hole, the more concentrated the force will be.. etc.
You can see there are a number design factors that will contribute towards this possible circumstance.
In testing and developing the current Beco Balls we have to be conscious of the suction force and it's concentration to ensure it cannot replicate the effect you are suggesting. The wall thickness around the aperture, the material elasticity and volume make it impossible to produce the effect described.
In other, weak rubber or synthetic rubber balls the manufacturers typically increase the wall thickness to increase product durability. This in turn makes it harder to crush the ball flat.. Making any suction force created when the ball is crushed inevitably very high!
You will notice, the instance when this happened the ball was very thick and tough. It was actually sold as a rough and tough toy.
The hole itself was relatively very small. This meant the suction force generated was VERY high.
The owners couldn't actually pull the ball off the tongue!
In a simple test, if you manage to make a suction with a BecoBall... simply test how much force you need to pull the ball away and then image how easy it would be for the dog.
In most cases, the mildest of shakes and the ball will drop'
