My friend says between 7-10 days, and puppies show no signs of discomfort at all. If they were very distressed, the mama dog would be unsettled and upset, but apparently if done properly, this does not happen at all.
Mind you, I'm of the opinion that it's generally unecessary to crop and dock....I wanna tailed Rottweiler one day!
