I would agree on the statement that Doberman's due in fact play rough, although I personally have never had an issue with ANY ear injuries due to this, and up until now I have always owned a pair. But point made. Though I have to bring up the Rottweiler, also a guard dog with similar ears...not cropped.
As far as cleanliness I have to say I think this one could go both ways...as I said earlier it seems if this were the case many hunting and water retrieval dogs would also have cropped ears....especially for breath-ability for water retrieval breeds. I see your point I just think if this were in fact true, those breeds that are in the woods and water would have been cropped at some point in the beginnings of their development as a breed.
This one I can not comment on...your point seems to make sense but I have no opinion either way as I have never heard this argument...I'll give you that one.
On this point I wholeheartedly agree, the look of the cropped Doberman has evolved from the scrappy mutts (No offense Louis, you did a great job) of Louis Dobermann, into a breed that literally takes my breath away. The cropping only adds to the dignified, stoic look of the Doberman. It is an International symbol of protection...I have always loved the look of a well cropped doberman. But in saying that...This is in fact COSMETIC ....the same loving, fearless, agile, protector is there cropped, or uncropped. Although he may not APPEAR to others as that, he will in fact if pushed, prove it.
Very thoughtful ideas!
On
ear injuries: incurred in scraps with other dogs: I am not only talking about two or more Dobes playing or scrapping together. I am talking about fights with any other dogs. I wouldn't think my Dobe could wind up needing stitches on his anus but it happened. I can easily imagine an ear getting cut, and I have seen pictures posted by folks here of pieces missing from ears. I don't want that liability. I can, however understand that some folks have never had a problem with this. I will add on your example of the Rottweiler: The Rott's ears are quite a bit smaller, and are coupled with a much larger, rounder head. The amount of ear leather flapping around loose and away from the head/face is much less. On this note, it's a bit surprising that fighting and war dogs with massive heads and relatively small ears have been historically cropped. It lends credence to the theory that more ear leather is a liability in both fights with humans and with other animals.
On
ear cleanliness: Hunting dogs that are worked in the field, as well as other dogs, may deal with periodic ear problems. I don't really know, except for the what I hear from
@AresMyDobie regarding her past Golden. (Now, her Golden might have just been a dog prone to ear problems, and as such not a good example in this argument - no offense, AresMyDobie). I've never had to take my Doberman to the vet to treat an ear problem, nor have I done anything more than take a Q-tip and alcohol to them when they seem dirty or when he holds an ear down a bit making me think it's bothering him a bit. So, I don't really know for sure if having floppy ears does lead to more ear cleanliness/health problems. It makes sense to me that it could, and that would point to a non-cosmetic benefit of cropping. Now, were ear cleanliness the
only reason for cropping, would I go through the major stress of cropping and posting? Probably not. One more point: I wonder if hunting breeds and the like have something in their breeding that has helped them adapt to their use and thus not suffer as much from dirty, moist ears. Really, to me, a Doberman should be expected to traverse many types of terrain, and operate in many types of environments in the execution of its job, including all the types of terrains and environments in which hunting/retrieving dogs operate (including traversing bodies of water

). I don't think, however, Dobermans have been worked all that often in such conditions through the generations, and as such I doubt any adaptation has occurred.
Now, when you say that the deterrent factor that cropped and standing ears provide is
cosmetic: It is in fact a cosmetic alteration; but it is a cosmetic alteration
that serves a very real purpose and thus is not purely cosmetic. It is not done simply to gain a specific look just for the sake of the fact that folks may like the look. It enables the Doberman to perform its job better. Remember guarding and protecting consists almost exclusively of deterring.

I think all this great discussion on both sides of the "cosmetic" argument should be moved to ether a new thread, or added to on existing appropriate one. I think it's very important discourse for present and future users to have at hand.
