7th week: “During this week the body hair grow out and color will be visible. The paws and pads are now ready formed. Fetus now looks like the puppy but cannot survive outside the womb. From this stage it is really only size to increase. The bones are now so developed that, from day 49 it is possible to see the fetuses on X-rays.
It is now for the first time in pregnancy possible to see fetal movement. Females belly is in most cases clearly increased, and milk production has begun.”
