Depending on the size and breed of the dog, heats (estrus) can begin as early as four months old and can occur as frequently as every four months. Spaying a dog either through ovariohysterectomy or ovariectomy is the most effective way to prevent pregnancy. Spaying also negates false pregnancies and pyometra and reduces the risk of mammary cancer. Drugs that regulate the heat cycle are not approved for use in the US or Canada.

A caesarean section is a major surgery to help deliver puppies, usually performed in an emergency. After surgery, the dog may be sleepy but should be able to eat a high-quality diet and nurse puppies within a few hours. The dog should be monitored for fever, abnormal vulvar discharge, and abnormalities at the incision.

Eclampsia in dogs is an emergent condition of hypocalcemia that generally occurs one to four weeks after whelping but can also occur shortly before giving birth. Risk factors include a poor diet, small breed dogs, abnormal parathyroid gland, and calcium supplementation during pregnancy. Signs of eclampsia start as restlessness, panting, and stiffness and can progress to disorientation, tremors, inability to walk, and convulsions. Treatment includes intravenous fluids, careful intravenous calcium supplementation, and other supportive medications. This is followed by oral supplementation and weaning puppies as soon as possible or supplementing their diet with milk replacer.

Female dogs will have their first estrous (reproductive or heat) cycle when they reach puberty. Each cycle consists of several stages; the stage called estrus refers to when the female can become pregnant. This handout explains the cycle stages and signs as well as how to prevent mating and pregnancy in your female dog.
-
Estrus (heat) begins when a female dog reaches sexual maturity and occurs about twice per year, although it varies from dog to dog. From the beginning of a female’s estrus period, she will be attractive to male dogs, though she will usually not be receptive or allow mating until seven to ten days into her cycle. The time of mating is extremely critical and it is highly recommended to have your female tested to determine the optimal days for breeding.
-
False pregnancy refers to a display of maternal behaviors, combined with the physical signs of pregnancy following estrus, in unspayed female dogs that are not actually pregnant. Signs include physical and behavioral changes, outlined in this article. Mild cases typically are not treated, but treatment may be needed for more serious cases. If your dog is not used for breeding, spaying is recommended.

This handout discusses the need for ensuring your pregnant dog is receiving adequate nutrition to make sure both she and her puppies thrive during this time of increased demands on her body. Feeding and diet suggestions are provided.

Special attention needs to be given to a dog’s nutrition during her pregnancy to promote a healthy birth and healthy puppies. It is important to maintain a good body condition throughout pregnancy as her weight increases. A good quality adult maintenance diet is recommended during the first 40 days but after this the energy demand increases greatly and this is most easily met by feeding puppy food. This diet is usually fed throughout the lactation period, but attention to body condition is essential here as well, and the diet may need to be restricted if there is a small number of puppies or the dog starts becoming overweight. Weaning is usually aided by feeding significantly less food for a few days while restricting access to nursing to decrease milk production.
