That IS really neat. Is there a reason that their tails get docked? (Curious, don't mean anything negative. I don't know the breed standard).
Congrats on the beautiful litter!
Three reasons for modern docking of this breed (not saying they are good or bad reasons, just reasons.)
#1 It's required by the breed standard
#2 Tradition
#3 Making them all the same length so the breed is more uniform.
#4 least of all, easier grooming on working dogs, if it's gone you don't have to cut burrs out of it obviously. At least that's been my experience having the only bob tailed dog on a SAR team full of Golden and Flat coated retrievers.
These puppies will be banded today.
