Canine Gestation Calendar
| Week | Changes

Male and Female in a Tie (bred)
Zero to One Week |
Females will usually come into heat every 6 months.
Some breeders will breed second heat, some breeders will not breed until the female is 24 months of age
Regardless of what age a female is bred they can only be bred when they are in "heat".
Heat is when a female is bleeding and soon to be receptive to a male's attentions.
Standing Heat is when bleeding stops and a female will flag and will let a male mount her.
Flagging is when the female will lift her rear and put her tail to the side if you touch her rear or if a male sniffs her.
Standing heat usually occures 10 days after you see initial bleeding and will last up to 16 days after initial bleeding is seen.
- After a Breeding takes place you will generally know the male has connected when he is breeding and lifts his rear leg.
- Male remains joined inside female as his bulbous glandis swells inside the female, locking them together for a few seconds to hours.
The male will try to lift his back leg over the female so he is more comfortable rear to rear.
- Within a few days, the sperm reaches the eggs and fertilization occurs.

Fetus @ 2 weeks of age
Week Two |
- The fertilized eggs make their way to the uterus for implantation.

|

Ultrasound of fetuses @ 4 weeks of age
Week Four
|
- Fetuses can be felt (Palpation) by Vet in the uterine horns around day 28, and can also be seen by ultrasound.
- The spinal cords are developing, and the fetuses are beginning to grow facial features.
- Your bitch's uterus will shortly fill with fluids to protect the fetuses. After this, it will be weeks until the puppies can be felt again.
- After day 30 in the fetus, unborn pups form eyeballs and vision similar to a color-blind human, who can't discern red, yellow or green. Scientists believe that dogs' color blindness adapted from their earliest ancestors who needed to compete for prey against other animals during nighttime.
- Your dog's appetite will likely increase, so offer her more of her food.

Week Five
|
- The fetuses develop their sex organs and begin to look like actual puppies. The leg buds lengthen and develop toes.
- Your dog's belly will begin to look noticeably swollen as the pups take up more space.
- With less room for full meals, it's time to begin serving smaller meals more frequently.

- Pups continue to grow and pigmentation develops. The eyes now have lids and remain sealed until approximately ten days after birth.
- Your dog is noticeably more uncomfortable at this point. She may vomit occasionally due to the extra pressure against her stomach.
