I have 4
Caucsaian Ovcharkas and they all have what is called a Shepherd's Crop. The Ears are cropped at about 3 days old and are cropped close to the skull. This cropping of this breed and many others was a way of protecting the dogs from severe ear injury in their combat with wolves and other predators.
Now with limited or no predation in the USA urban and some rural environments the question could be raised as to whether it is still necessary. My preference is that the ears are cropped. I have seen my dogs play and if they had natural ears I would spend a fortune at the vet repairing ear damage.
The only issue I had with the cropped ears was the frequent foreign objects that would find their way into the ears when the dogs would run through underbrush or bushes. That sometimes required a visit to the vet to remove the objects.
You have a neo x APBT so I a guessing that you would call it a
Bandogge. You can find some pictures on different Bandogges at
this link. Even if your dog is not a Bandogge the pictures could give you and idea about the crop or natural ears.
I also realize that this thread is old and this point may be moot so I am posting for the benefit of others who may have a similar situation.
Crop or not to crop is a personal decision so do whatever you are comfortable with. Others (including me) advice on the subject is just that, advice. The decision, gentle reader - is
yours.
