Sub-Critical Overflop



Due to the vigorous up and down motion of spretting, and the developed size and area of some types of beaglia ear-appendages, spretting can occasionally lead to a sub-critical over-flop, whereby the beagles ears' flop up and down in motion with the resonant frequency  of the ear's swing-length. In such cases tremendous amounts of kinetic energy can build up in the ears of different beaglia, and when such spretting is continued for extended periods of time can set into motion a harmonic oscillation  of ear flops, potentially leading to bruised and swollen cheeks, sore ears, reduced ear softness and hair loss.

Apart from carefully controlled laboratory settings, spretting in the wild does not usually exceed the level of a sub-critical over-flop. In some legends passed down across the ages, exuberant spretting by overweight beagles has lead to catastrophic consequences (see Critical Overflop).
