From the beginning of the heat period she will be attractive to male dogs, but will usually not be receptive, or allow mating, until about 7-10 days later. The discharge will usually become less bloodstained at this time. Some females experience heavy vaginal bleeding during oestrus.

Look for the sudden drop in temperature that occurs 24 hours before birth. The normal temperature of dogs is 100.5-102.5 and the usual drop in temperature before parturition is to below 99 degrees.

The normal gestation period is 63 days from the time of conception. This may vary if the bitch has been bred two or three times or if the eggs are fertilized a day or two after the mating has taken place. Eggs remain fertile for about 48 hours. Sperm can live in the vaginal tract for several days.

Each dog is different and a cycle can average from two to three weeks. Visual signs that your female has started her heat cycle will be a discharge from the vulva. You may like to use a high tech machine to help determine when she will come into heat and this one on Amazon will do just that.

Most dogs will show no signs of pregnancy for the first several weeks. It will be difficult to determine if your dog is pregnant early on. Signs typically appear in the second trimester (about three weeks into the pregnancy).

Good question to ask if its ok to spay her if she has just come into heat. Dogs can be spayed while in heat, but may be more prone to bleeding and some other surgical complications. Many veterinarians prefer to wait until the heat has ended to reduce the potential for complications.

Dog pregnancy usually lasts between 61 and 65 days, but you may not notice any obvious physical changes in your dog until she is already well into her term. There's no such thing as an at-home dog pregnancy test, so you'll have to look out for common dog pregnancy signs yourself.

There is little information about simultaneous occurrence of pyometra and pregnancy in bitches (Orozco et al., 2005). This present report confirms that it is possible for a bitch to have both pyometra in one uterine horn and a successful pregnancy in the other with proper medical treatment.

"In fact, any of the species that have litters and can be bred multiple times during one heat cycle can have offspring with different sires," she said.
