Growth and Development of a Fetus







Week One - Days 1-8

During the first week the 2 cell embryos are in the oviduct. At this point
NO live vaccines or treatments that contain insecticide should be used. You may notice that the bitchs personality may begin to change. Mine usually become more affectionate and want to be on my lap all the time. This is a good time to weigh your bitch and keep records to see how much weight she gains during her pregnancy.

Week Two - Days 8-14

During the second week the fetus grows from a 4 cell embryo to a 64 celled embryo, and this is the time that the embryos enter into the uterus.

Week Three - Days 15-21

During the third week the ovules have changed in shape in order to become embryos that adhere to the walls of the uterine horns; the  nervous system is already formed. The personality changes become more prominent and morning sickness may occur.

Week Four - Days 22-28

During the fourth week the puppy grows from five to ten millimeters, and starts its development. The spinal cord and eyes have developed and the face has taken shape. This is a critical time for the embryos as this is when it can develop birth defects.

 Days 26-32 are the best days to palpitate for puppies. I recommend that only a vet or an experienced breeder do this. The dog may experience some vaginal discharge and her mammary glands will begin to develope. At this time you should limit ALL strenuous activity, jumping or extensive running. 

Add protein to the diet in the form of cottage cheese or hard boiled eggs every other day. I also add hamburger meat. At this time I exchange their dry dog food to puppy food.

Week Five - Days 29-35

During the fifth week the fetus grows another 12 millimeters and begins to resemble a puppy. The toes, claws and whisker buds start to develop and their internal organs finish developing. At this time the gender can be discovered through an ultrasound. Fetal eyelids develop and close over the eyes.

Week Six - Days 36-42

During the sixth week the fetus should weigh 6 grams and measure 45 millimeters in length. The Heartbeat can be detected at this time with a stethoscope, and the pink pigment on the skin is now developed. The dog's nipples should be enlarged and darken. I continue giving  my dogs  puppy food and continue to give cottage cheese and  boiled eggs for a natural source of calcium and hamburger meat, as this helps with the high protein needed. Abdomen continues to get larger, depending on how many puppies she is caring

Week Seven - Days 43-49

During the seventh week,  from this moment on the growth of the fetus is very fast. The hair on the bitches abdomen will begin to shed and the nipples should be bigger and darker. Sometimes you can see the outline of the milk sac's around the nipples. Most dogs will have a clear discharge which is normal. The puppies can be felt moving and are still growing and the abdomen continues to get bigger.

Week Eight - Days 50-57

During the eighth week the fetuses are already calcified and therefore can be seen by means of x-rays/ultrasound in order to verify their positioning and approximate number. Puppies continue to grow and if born at this time, the puppies would have a good chance to survive as this is their safe period and their lungs are strong enough to keep them alive. At this time the puppies will become more active and can be seen or felt moving.

Week Nine - Days 58-65

During the ninth week, the fetuses have already completed their prenatal development and are ready to be born. From the 58th day on, whelping is imminent. Puppies will come soon. Make sure you are prepared. Have your whelping box and necessary tools. I start taking bitches temp 3 times a day, and keep a record. When the temp gets to 98 and stays, I know she will be having her puppies with in 24 hours. Not all dogs are the same, that is why I try to keep good  records. Make sure you have notified your vet in case there are any problems.

This is my friends dog, we knew she was pregnant but not very big so  she had her x-rayed to make sure it was not a false pregnancy, Well she only had one puppy and the vet said it would be to big to free whelp, so she scheduled a
c-section, This probably saved the puppies life and maybe even the mother. Puppies were not due till March 3, and she had her x-rayed on Feb 27th. This x-ray below is of Millie with one puppy. I have outlined the puppy in red so you can see it more clearly.

This is one of my dogs and she free whelped. And is giving her pup lots of kisses.
