Aside: A similar question is often asked by folks when I practice my bagpipe chanter. I suspect it is a question of taste on their part and skill on my part without any true consideration of the dog's otic health
Answer:
A dog's ears hear essentially the same as we do with a better registering of higher end frequencies (in excess of 20K Hz) We call these frequencies "ultrasonic"
Pain from sound is caused by air pressure from the pain (loudness). Noise levels of 85 db can cause hearing loss over time. Noise levels of 140 db can cause pain.
A harmonica at its loudest is not in the painful range to the player (the closest set of ears) although it may be detrimental over the years. Sound levels fall off with every doubling of the distance, so at a dog's ear level the sound will be much reduced from that reported by the player's ears.
As a test - consider that dogs can bark loud enough to hurt our ears Dogs ears are closer to the bark than our ears and the sound from their point of veiw is much louder. Barking does not harm a dogs ears.
because the noise might be a dog atack noise and it could really hurt there ears
No, pig ears are a good chewing treat for dogs.
No, you do not "have to" crop any dogs ears.
yes
Wild African dogs have big rounded ears to be able to hear at greater distances than domestic dogs for purposes of hunting and defense.
Dogs are very sensative to it so I think it might hurt their ears. But who knows maybe they could be singing :)
Of course it hurts! Do not crop dog's ears! Don't listen to them, you can have a dogs ears cropped. Obviously it does hurt them, but that is okay.
Yes, unfortunately, they can. Some dogs may not be hurt, though. They may simply be surprised or scared of the loud noise/big shiny metal thing.
for most people it does hurt to get your ears pierced.

It shouldn't provided it is used properly. A dog whistle is a whistle that produces a pitch that is too high for most people to hear, but most dogs can hear. However, if you blow the dog whistle in the dog's ear, yes it will hurt the dog's hearing.
When a dog has cold ears, it could mean a number of things, if you haven't already, bring your dog inside and keep it warm. Dogs ears are sensitive so do not rub them, it may hurt your dog. Once your dog is inside, check his ears again. Are they still cold? If so it may meet he has bad circulation or heart problems. If the dog has long ears he may have dipped them in his water bowl by accident. If the dog is sick, the cause of the cold ears could be that the blood and heat are all circulating around his major organs, rather than his ears.
at beauty mart and no I wasn't scared when I had my ears pieced and it did hurt
giraffes hurt dogs
No, pig ears are a good chewing treat for dogs.
your ears hurt when you are in an aircraft because of the change in air pressure when you are in the air
well if the amplitude is too high it can damage their ears. if its at the right frequency and amplitude it will still hurt but that's how it trains them
