Maturity in Females
Bitches come in heat approximately every seven months. Most Newfoundlands reach sexual maturity between six months and 12 months. The bitch’s cycle is non-seasonal; meaning it is usually not influenced by the time of the year. It is divided into the following stages
1. The bitch will have a swollen vulva and pink/bloody discharge. Males will be attracted to her but she will not accept them. Usually lasts 5-9 days.
2. The bitch will still have a swollen vulva, but the discharge changes from bloody to clear. The bitch will accept the male. Usually lasts about 9 days.
3. May have phantom pregnancies or may get pyometra. During the 8 weeks after start of heat.
You should keep the bitch away from males three weeks from the start of the heat.
is a result of hormonal and structural changes in the uterus lining. This
can happen at any age, whether she has bred or not. The main risk
period for a female is for eight weeks after her peak standing heat has
ended. Normally during this period, the cervix, which was open
during her heat, begins to close, and the inner lining begins to adapt back
to normal. Under these circumstances, bacteria that have migrated from the
vagina into the uterus find the environment favorable to growth, especially
since progesterone also causes mucus secretion, closes the cervix
(preventing uterine drainage), and decreases uterine contractility. The
condition of the cervix is a major factor in the severity of the condition.
Phantom pregnancy: A phantom (false) pregnancy is when a bitch is not pregnant but shows signs of pregnancy, lactation, nursing and nesting. Phantom pregnancies are not uncommon.
An intact female dog will experience changes in their reproductive hormones
during their season. Individual dogs vary in the length of time between
seasons, and this is to some extent inherited from the mother.
