Nah, wouldn't dream of it. But then some of my pups would only come out with half a pedigree as Dad not KC registered :-)
I use word processing or spreadsheet, easy to change and add stuff, but my dogs are 'dual' registered and the KC aspect of their registration is pretty insignificant to me. So pups go with 2 versions of their pedigree ... one showing the 'important' stuff :-D and the other showing just the KC registrations behind them. Putting them into documents on my computer just makes it easier for me to customise. OK, it's a total faff when you first set out your template, but once done it's done and not that bad to amend in the future.
Oh, also it's a lot cheaper. Me reckons the KC gets far too much money already without paying good money for a bit of paper I can produce better :-D
