> my concern is obviously when she has the pups what process should I do to put them in the whelping box because even though she can have the Pops there now it's not big enough for her to be there with the puppies.<br />
Why not big enough? It should be!! As said I had mine sleeping in the whelping box for a week before the due date, with me in the same room on a cot so I could keep an eye on things through the night and so she became familiar with those surroundings.
Mine tended to suffer with secondary inertia - as soon as contractions began, it was ouch mum..... you had them put there, now you get them out!
I'd be careful about a vet saying wait 'as long as she's not straining'. In theory maybe, but again if the puppies are just sitting there (sometimes with a small litter, they do) they are growing by the day, potentially making a C.Section more likely to be needed. As said, if mine went over by more than 2 days from the first mating (recognising that conception may not take place immediately), then I'd need to involve my vet to at least take a look. It is a fine balance between just leaving things, and taking a pregnant bitch near a vet's office (risk of infection/stress), although of course, he should be able to check her without you actually taking her in.
Hopefully she's had her puppies by now!
