Giving birth can be a frightening, confusing and painful experience for both the dog and the owner. Knowing and understanding normal labor and delivery, as well as proper pregnancy care, can help make the process go more smoothly and help you know what is normal and when it is time to get the veterinarian involved.

Gestation

In the bitch, a female dog, gestation lasts 63 days. Knowing the exact time of conception, however, is difficult since a bitch can be receptive to the male before and after ovulation. For this reason, the time from breeding to delivery is usually somewhere between 58 to 70 days. Your veterinarian can help narrow this time frame by examining the cells of the vaginal wall.

Be aware that just because your bitch bred does not mean she is pregnant. Some dogs will even show signs of pregnancy and not really be pregnant.

There is a phenomenon in dogs known as false pregnancy or pseudocyesis. For confirmation of pregnancy, an examination, with ultrasound and possibly X-rays by your veterinarian, is suggested.

Nutrition

Once pregnancy is confirmed, proper care of the mother-to-be is very important. Before breeding, make sure she is up to date on all her vaccinations. It is not recommended to vaccinate your dog during pregnancy. Also, make sure she is dewormed and tests negative for a bacteria known as Brucella. This bacteria can cause abortion in dogs and is also contagious to people.

After breeding and conception, most bitches do well during the first 4 to 5 weeks of pregnancy and do not need any special treatments. Things start to change during the last trimester (week 5 to 6). The babies start to rapidly develop and this results in a significant nutritional drain on the mother. At this time, you may want to consider gradually changing her diet to a growth type diet or a food specifically made for pregnant or lactating bitches. Continue this diet throughout the remainder of pregnancy and until the puppies are weaned. Vitamins or other supplements are not recommended nor needed. With a proper diet, your dog will receive the proper amount of nutrients. Excessive amounts can actually result in birth defects.

Do not begin feeding your dog a higher calorie food before the last trimester. This can lead to weight gain and fat deposits. This has the potential to cause difficulty in maintaining the pregnancy and can result in problems delivering the puppies.

Preparing for Delivery

As the time of delivery approaches, you may want to make a whelping box to provide a safe and clean area for your dog to deliver. Whelping boxes are intended to be easily accessed by the mother but escape proof for the new arrivals. You can use wood, Formica or any building material that is easy to clean. Make the box large enough for the bitch to comfortably stretch out. Make sure the sides are just low enough for the mother to step over and place the box in a warm, dry, draft-free area. If possible, try to choose a quiet and secluded area. Initially, place newspapers on the bottom of the box for easy clean up. Once all the puppies are born, place blankets or towelsWee Wee Pads

Be aware that you must get the bitch used to the whelping box before the birth. If not, she may make her own decision on where to have the puppies – and this may be a closet, a pile of fresh clean laundry or even in the middle of your bed!

An additional suggestion is to have your dog examined by a veterinarian toward the end of pregnancy. A thorough physical exam, along with ultrasound or X-rays can help determine how many puppies you can expect. This way, you will know when she is done delivering and not just in another resting phase between pups.
