i tell ya i have spent many sleepless nights delivering pups (15+ litters) and each time is like the first it never gets old , its when they are 5wks old it starts to get old they are hellish at that age i have seven so far she went into labor about 1am its 4am now , so far very smooth a pup is being born about every 15min or two every half hour . just for the record if anyone is interested in purebred american bulldog pups bred from top quality working stock , let me know . i will post pic when they are older
