Our understanding that a dog is pregnant is only possible in the last weeks of the nine weeks of pregnancy, when his belly becomes colossal. The best way to learn it is to take your dog to the vet, but it may be useful to be aware of the physical and behavioral changes that may occur.

The nipples will swell and become more prominent in a 25-30 day pregnancy. About a month after mating, a vaginal discharge will begin to develop. 45-50 days after being pregnant, you will notice that his abdomen is swollen because of his weight gain. Some dogs will also show signs of loss of appetite or depression during the gestation period (pregnancy).


If you think your dog is pregnant, you have to take her to the veterinarian. The aim of this is both to confirm pregnancy and to detect any complications that may occur in the early period. Your veterinarian will use a number of different methods to determine if your dog is pregnant. After 20-21 days, your veterinarian can only perform a test to determine the level of relaxin, a hormone produced by pregnant dogs. This method will verify pregnancy, but will not give information about the number of offspring.


There is not much you need to do for the future mother, except to ensure that you are able to maintain a good, healthy diet in the months before birth. You should encourage him to exercise to preserve his long, tiring form of labor.

In the days before you give birth, your dog will probably start to be uneasy and get back on the floor or bed. She tries to make a nest for birth. You need to give him a space covered; this should ideally be a place where they can enter and leave, but keep their offspring in limited space.

A cardboard box of suitable size for your dog will see this or you can consider providing a small children’s pool. Fill the “seat” with towels, blankets or old covers. Since birth tends to be a dirty job, do not use anything that is intended to be reused.
