I don't have a CC, but I've had boxers for more than 20 years and they're a breed where cropping and docking has been hugely debated. I've also had both cropped and uncropped dogs, as well as having fostered natural tailed dogs. I didn't notice any difference in frequency of ear infections or ease of cleaning in natural vs. cropped dogs. My cropped boy never had an aural hematoma and two out of four of my natural eared boys did. Hematomas are nasty things, but each of those dogs had allergies and the hematomas were late in life. As for tails - I will always dock if I am able. I don't know if a CC has as happy of a butt as a boxer, not many dogs do, but tail injury is pretty common in the boxer breed. I fostered several natural tailed boxers that had to have their tails amputated due to repeated injury. Done at a few days old it's a docking and while it's not painless, the pups are back to playing in a few minutes and don't seem bothered by it much past the actual procedure. Done at a later age it's an amputation, is very painful, and takes a lot of time to heal. Ultimately I think it's the owner's choice, if the law allows.
