What is a dog’s life cycle

What is a dog’s life cycle?


The lifespan of a dog will vary by species. However, for dogs that are popularly raised, they can live for less than 10 to 20 years. And the stages in their life cycle are the same, including the Embryo stage, Puppy stage, Adolescent stage, Adult stage, Senior stage, and finally Death.

Therefore, we will analyze these periods as calculated for the more common species. The following is a table of age measurement for dogs by each stage.

#1: Embryo Stage

For medium-sized dogs, from conception, puppies will be in the womb for about 58 to 68 days.

For small-sized dogs like Chihuahua, Japanese, Beijing, etc. and those with less than four calves/litter such as Rottweiler, Golden, etc., it will take more than 2 months.

Just like humans, initially, fetuses in dogs begin to form an implant in the mother’s womb. The development and completion of the basic functioning of the puppy’s body start from 6 months of pregnancy. So, when the puppy is still in the womb, you need to provide enough nutrients for both mother and babies to be healthy and develop normally.

In particular, after six weeks of pregnancy, you should change the diet for the mother dog from 2 meals to 4-5 meals a day with the amount of food unchanged. Besides, it’s essential to supplement the two foods that are good for blood and bones – beef and duck eggs at 1-2 meals/week.

#2: Puppy Stage (0-12 months old)

This is the first phase, but it is very important because it will affect the social skills of the pet. Therefore, you should let the puppies live with their siblings for at least the first eight weeks of life.

After birth, the mother will feed the babies entirely with breast milk, and after two weeks, the puppies can taste and smell.

If you are taking care of a newborn dog, you probably expect him to open his eyes. However, you will have to wait for one month. At this time, puppies also start to develop hearing and smell. Their teeth begin to grow as well, so you can feed them washy porridge.

In the first six months of the life cycle of a dog, puppies will need 2-4 times more food compared to adults to grow fast. Foods rich in nutrients such as fish, meat, and eggs should be included in your dog’s diet.

From 3-6 months old, puppies start to learn hierarchy in their herd because they often compete for each other when playing and eating.

#3: Adolescent Stage (10 months – 2 years old)

After 7-9 weeks, they complete their senses and play more. Later, they begin to explore their surroundings. Therefore, you should create conditions for them to go out to nature more.

At one year of age, if the dogs are not taken to the veterinary to have an ovary removed (female) or castration (male), they will go through a period of oestrus.

You can notice signs of puberty in pets. They also start to become more aware of gender differences in species and change behaviors. Sometimes, you can feel annoyed by dogs being very stubborn and naughty. However, it is reasonable because their hormones during this period are more active.

In particular, this is the right time for you to train your pet. They can perceive and very curious. In addition to the herd, they can also learn from their owners. You can teach them to eat, sleep, pee in the right place and many other lessons.

#4: Adult Stage (2-7 years old)

Depending on different species, after 1-2 years of age, dogs begin to act more mature. At this time, they will still run and eat a lot, but you will no longer have headaches and be busy because of them.

Instead, your pets have been fully trained and become more obedient. You will feel the affection of your dogs every time you pet, feed them, or take them for a walk.

You can also teach them more advanced lessons to train their physical and mental health. Thanks to that, the dog’s life will also be happier.

#5: Senior Stage (6-10 years old)

Growing old is indispensable in a dog’s journey. They start this period from 6 years of age, while smaller species will experience it 3-4 years later.

The sign of a dog entering the senior period is that their functions are impaired. They move more slowly, eat less, and get sick more. Some will have hair loss or ragged.

As they get older, most of their time will be for sleeping. Some may even have poor memory or the inability to excrete themselves and have to use diapers, etc.
