I think you need to supervise your bitch in season better.

I think you need to do more research about breeding in general since increasing diet and caloric load before week 6 can lead to issues in some bitches.

I think vaccinating a bitch who might be in whelp is VERY UNWISE!!!!!! ESPECIALLY RABIES!!!!

I think you should research Von Willebrand's Disease in Scottish Terriers.

I think you should have an ultrasound done on your bitch to ascertain for CERTAIN if she is in whelp.

And I really think you should spay your puppy and forget about breeding.

JMO of course....
