This is really a matter of personal opinion as this is really only a cosmetic operation. There are generally four accepted styles of ear crop for Pit Bulls: the Battle Crop, Short Crop, Show Crop and Long Crop. The Battle Crop involves removing the entire of the outer ear and, as its name suggests, is usually seen on Dogs destined for the pit. The Short Crop is one of the most common crops seen on Pit Bulls and involves leaving only a small amount of the outer ear intact. The Show Crop is for owners who want to show their Dogs and involves the ears being shortened slightly and cut into the desired pointed shape so that the Dog looks smart and alert for the show ring. The Long Crop is quite rarely seen on Pit Bulls and takes the longest to heal, it involves leaving the ear as long as possible and only trimming what is needed to give a nice pointed shape. So, it is up to you.
Cropping is illegal in the UK and should be in the US, it's cruel and pointless. Crop and tape your own ears. http://www.petforums.co.uk/dog-health-nutrition/6565-ear-cropping.html
Most puppies are cropped between 10 and 12 weeks of age but it can vary depending on the weight, size and health of the puppy. Your veterinarian will advise you on the best age to crop your puppy.
Some people prefers the ears uncut but most prefer the ear low-cut like me. They are suposed to look like you want. There are various type of ear crops depending on the length you want them: battle crop, short crop, show crop, and long crop.
Ear cropping is illegal in all of Australia, but it is still legal in most of America and Canada.
All puppies are born deaf, their ear canals are not open. The canals start to open at about 10 days old. As soon as the canals are open a puppies hearing is very accurate.
A puppies ear canals are sealed. It takes them about ten days after being born for their ears to finish development. After this, the canals will open on their own. The puppies hearing will be very acute as soon as this happens. Another reason is that dogs have very keen hearing, when they are little, the sounds would be deafening if they could hear them.
