It depends on the species of animal. Most mammals have some kind of period.
Some of our evolutionary cousins, eg chimpanzees have similar menstruation to humans where they bleed the lining of the uterous at the end of their period. However most mammals don't do this, a lot of them reabsorb the lining back into their body.
Obviously animals that lay eggs do not have a period.
What else can I help you with?
Do animals have periods?
Only if they are girls! But yes they do have periods. Otherwise they could not have babies..... No matter what I'm pretty sure that girl dogs do have periods. So yes animals do have periods!
Do smaller animals have longer gestation periods than bigger animals?
Not necessarily. Gestation periods can vary greatly among different species regardless of their size. Small animals like mice can have shorter gestation periods compared to larger animals like elephants. The length of gestation is more closely tied to the specific reproductive biology and development of each species.
Do animals who live in the water have shorter gestation periods than animals who live on land.?
I don't think so but maybe it is. But out of prediction I can say that animals that live in water have shorter gestation periods than animals on land because it takes a baby 9 months to get out of the mother's womb. Just my guess.
Do other animals have periods?
Yes, some species of mammals, such as monkeys, apes, and some bats, have menstrual cycles similar to humans. Other animals, like dogs and cats, have estrous cycles, which are similar but do not involve a shedding of the uterine lining like human periods.
Why do larger animals have longer gestation periods?
Larger animals have longer gestation periods primarily because their offspring need more time to develop fully in order to survive in their environment. The growth of larger animals involves more complex anatomical and physiological systems, which require extended periods for proper development. Additionally, larger species often have lower reproductive rates, leading to a longer investment in each individual offspring to ensure its viability and survival. This extended gestation allows for more advanced development at birth, enhancing the young animal's chances of survival.
What animals have periods?
Humans and chimpanzees are the only animals that have "periods" or menstrual cycles. Other animals of the animal kingdom undergo Estrus, or heat periods (spikes in Estrogen output) during their Estrous cycle.

Do animals have peirods?
Not all animals, but most mammals do, hence why people have periods (people=mammals)

Do animals get their periods?
Yes, this is called "in heat." I don't belive it's as messy as a human.
What are some of the animals in the desert?
Camels are just one of the many animals that live in the desert. They can last long periods of time without drinking water.
What did the Polynesians bring with them?
In terms of animals, pigs, rats and dogs, which were all used for food. It happens that these animals can be kept for long periods onboard boats.
What is an anoestrus?
An anoestrus is a spell of sexual respite for certain female animals inbetween breeding periods.
What group of giant animals once lived in the Triassic and Jurassic periods?
That was the age of the reptiles the "Dinosaurs".
You had two periods in a month which one did you get pregnant with?
Humans don't get pregnant when they have a period. That's only for animals. Human females mostly get pregnant mid-way between their periods.
Which zone must plants and animals adapt to being exposed to the atmosphere periods of time?
The Intertidal Zone
