What age does pitbull menstrual begin?

Pit bulls, like all female dogs, do not have menstrual cycles. They experience estrus cycles, which are different from menstruation in humans.

Here's why:

* Menstruation is the shedding of the uterine lining in humans when pregnancy does not occur.

* Estrus is the period when a female dog is fertile and receptive to mating.

The age at which a female pit bull enters her first estrus cycle (heat) varies, but typically occurs between 6 and 12 months of age. This can be influenced by factors like breed, size, and individual health.

It's important to consult with a veterinarian for accurate information regarding your specific dog's reproductive health and estrus cycle.
