They do, it's unfortunate. We had an English springer spaniel growing up, and went to get him as a puppy. They had already docked his tail and didn't want to give him to us before doing his ears, and we were just like "oh no no, let us pay for that", they agreed, and then we never spoke to them again and his ears remained lovely and floppy.

He did have to wag his entire butt though because of the tail, unfortunately.
