A Puppy's Life to Dog-dom. Weeks 1 and 2. These weeks are very quiet in that the puppies can not see or hear for the first 10 to 15 days, they can not regulate their own body temperature - they are totally dependent on their dam and their environment for warmth, nutrition and stimulation.
This may not be possible on a large dog or one that has the puppies under the rib cage. A blood test to check for pregnancy is available. It checks for the hormone, relaxin, which is produced when the fertilized egg implants. The test can be done about 28-30 days into the pregnancy.
