They sit, they listen, they tap their paws, the clean the throat, they sing!!!!!!! Even I ‘howl’ with the songs, well, thats what hubby’s telling me…..... (”,)
I’m not 100% on this, but i suspect i has something to do with the harmonic overtones. Canines have a hearing range that extends much higher than ours, so maybe they’re wincing at those incredibly high frequencies and the best way to voice their displeasure is through barking.
A dog’s hearing mechanism is very sensitive. Many times more sensitive than ours. Certain high volume sounds can actually be painful. That is why they also howl when a train blows its whistle or and ambulance or fire truck sounds off. When the tornado warning siren sounds off here, the dogs all over town can be heard howling in misery. The howling also helps take the pressure off their ear drums.
