Yep me too,Ive got 2 puppies leaving in the next few days so Ive asked the owners if i can activate it today so they get 6 weeks instead of 4,both are fine with that.
It says its so the pups are covered quicker for the sense of urgency for the new owner,personally I think it is so petplan get their money faster.
i have always had my pups insuraed from the day i collect them as it then covers them from day one should need be. New insurance dont pay out for to up 28 days so even though they come with the free period i always make sure they are covered twice.
