The dog experiences the same impulse noise that the shooter does. If the shooter chooses to wear hearing protection, what bout the dog in the same environment? We do know from experience with hearing aids in dogs, that they are easily trained to wear the foam type ear plugs, which muffle the noise by 20 to 30 dB, enough to protect the ear from damage.
Hey, I'm just copying and pasting here guys!!!
