Mating and gestation
by zobelhund on 01 May 2011 - 23:37
First is how many times do you allow mating to occur? We mated 4 times, locked.
Second question is day 14 into heat cycle they bred first time. They bred again day 15. Then again day 17 and 18.
Gestation is around 62-64 days. When should I count from? First mating or 4th mating?

|did you do progesterone testing?|
count 63 days from ovulation, regardless of then the bitch was bred.

|gestation is 62-64 days from ovulation irrespective of date of fertilization|
eggs are viable to fertilization 2 to 4-5 days after ovulation.
If you do not know the date of ovulation (have not done progesterone tests), apparent gestation period can be 57-70 days, as sperm can live for 6-8 days easily. A bitch can ovulate 6 days after the last mating and can still take.

|i have never had a bitch go 62 or 64 days. i did have a litter that went 60 or maby i miscounted.|
i count from the first tie and 58 has been the lucky number. i have a litter that is due on 28 may. i hope she goes 59 and they would be born on my birthday.

|The later you mate her and still just make it, the shorter will the apparent gestation period be. If fertilization happens 5 days after ovulation, it can be just 57 days.|
The shortest is 57 days, I believe.
It can be 48-60 hours after ovulation before an egg can be fertilized and another 48-72 hours before it dies.
