I agree with everything already said. Especially regarding cruelty, as @GennyB said, the puppies act like nothing happened. I worked for a vet in the 1980's and he was a very popular one for ear crops on all breeds. I assisted in dozens of the surgeries, and yes, recovery is simply coming out of anesthesia. The litter goes right back to playing, bouncing around etc.
I will say that it is only the trend of longer show crops that takes so long to get to stand. Another thing about choosing a good breeder is that they will choose the puppy that fits your lifestyle, you don't go choose the puppy you want. That said, this is usually determined by 7 weeks or so, before the ear cropping. I asked my breeder early on if they could please do a medium crop on my puppy, not a show crop. Not all breeders will do this, but you could at least ask. The medium, medium-long crop is still longer than what they did in the '80's and what you remember with just a little time before they were done. My Dobe from the 90's was finished & standing before she was 5 months old. I don't think it's all to do with the length as now they remove the bell and that contributed to a ton of support.
My current dog with a requested "medium" crop - but I think it's more of a "medium-long". Posted through age 6 months and used the tape on the tips through 7 - 8 months of age.

Below is my dog born & cropped in 1991, not much shorter really, but the bell at the base gave it a different look and more support to stand quickly. I don't think many vets do this at all anymore due to the style changes.


Hope this helps!

Anyway, that's my way of saying she provides a great example of the majestic, alert, bright look of a cropped Doberman.
