Only humans, apes and some monkeys menstruate. Other mammals like dogs and cats sometimes will bleed a little when they are in heat, which is when they ovulate and mate, but they do not have menstrual cycles. Having a menstrual cycle means you do not go into heat. Because of this, humans are able to conceive during a period every month, whereas dogs only go into heat once or twice a year.
