Well if my friend had listened to the vet she would have spayed the bitch and not had the litter, which would have been a loss to the breed when only about 10 litters a year are currently being bred.
Remember the relaxin test can give false negatives. Some Amazon reviews:

This review is from: Canine Pregnancy Test Kit (5 tests) (Misc.)
I researched this product and it's reviews before purchase. I initial used this test on my bulldog at 25 days from last breeding with a negative result. I waited a week(as manufacture recommends) and re-tested with still a negative result. By the 35th day from breeding she was beginning to show signs of pregnancy and after an ultra-sound was confirmed pregnant (by visual and heartbeats). All three tests was preformed by my vet at $15.00 per blood drawl/spin and $35.00 for the ultra-sound.
What you should know before purchasing/using this test:
The amount of relaxin (serum relaxin level) being produced at the time of the tests depends on the breed, the size of the breed, the size of the litter, LH(luteinizing hormone) surge and when the test is preformed.
For example: If the litter is small there may not be enough relaxin being produced to react with the test. The same would be true if it is a small breed or preformed to early.
I now believe the best option for my female bulldogs in the future will be an ultra-sound as recommended by my vet."
In USA people can buy a lot of medications without prescription and do some procedures themselves legally.
