When our dogs come in the heat, we may ask ourselves a question: “Why, oh why on earth this is happening to me?” If you don’t know what to do with your dog, when she is in heat, you may become very nervous, as well as your dog, and this may end up a nightmare.
But back to your previous question. Why are dogs in heat?
Heat cycle in dogs ensure they may become pregnant and have babies
Heat cycle is part of a reproductive system in dogs. In short, dogs are in heat, so they can have babies, and do not go extinct.
Heat in dogs is somewhat close to periods in human. Thank god, while women menstruate every month (is it on purpose?), dogs normally are in heat twice yearly.
However, the whole cycle is happening without a stop and consists of four phases: Proestrus and Estrus, when dog is referred as being in heat and Diestrus and Anestrus, when we say the dog is not in heat.
Each part has different hormones influencing your dog, and each part has different tasks in order to make the miracle of the birth to happen… or not to happen.
- Proestrus serves as a preparing reproductive system of your dog to breeding.
- Estrus will be the hardest part of the heat cycle for you, when ovulation occurs, and the uterus is receptive for implantation. In this part the dog is extremely attractive to males, and vice versa, it attracts males the most. Also, this is the phase when your dog is able to become pregnant.
- Diestrus is the part that is responsible for sustaining pregnancy. No matter if a female became pregnant or not, hormone responsible for growth of the fetus has a high level and drops when diestrus is over only.
- Anestrus is the last part of the hat cycle in dogs, in which the reproductive system takes a rest and gains strength to undergo the next heat cycle.
And then it starts again from the top. And if you still have a question, why are dogs in heat, then it’s just how it works. It’s natural.
