Peter the cocker spaniel couldn't contain his happiness when he saw a flock of ducks during his morning walk and immediately fainted due to his rare condition called Myotonia Congenita.

The condition is a genetic disorder that affects skeletal muscles, which are used for movement, and is responsible for the eponymous 'fainting' seen in fainting goats when presented with a sudden stimulus.
