Interesting - I do like a smallish ear as called for in the standard although if you look at the standards of many other breeds of dogs in hot climates - they are larger as Andrea indicated for cooling.
I am more concerned with a couple of other things in our breed that are not so superficial. It's shoulders being set too far front, too upright and a short upper arm. What you end up with then is a B with what is called a catherdral front. As in you could park a church steeple between the front legs. This rusults in less room for lungs, less 'reach' so you will sometimes see fronts getting tangled up with rear if there is a good angle there.
It seems that more and more of our animals that are 'mature' (3-5) are looking as undeveloped as our puppies.
I'm not advocating bulldog fronts - but I do like to see something there.
The other thing is too little under jaw - you then get some heads looking awfully snippy and pointing nosed.
Oh well - I can't speak for the rest of you but I think in my kennel I have some very good parts that sometimes are not all on the same dog!
