When Is a Dog Considered an Adult?

Having a pet is wonderful, especially if it is a dog. Most people love puppies because they are adorable.

However, when they are very young, these animals can represent a challenge, especially for experienced owners, since they tend to have a high energy level at that age.

When Is a Dog Considered an Adult

It is important to remember that not all dog owners know everything about these animals, keeping in mind that each breed can be slightly different. Regardless, many of them wonder when their canines will reach adulthood.

The reasons why dog ​​owners wonder that are varied. Some want to know when their pets will be adults simply because they look forward to the time when they will no longer have a high energy level.

While others simply because of the fear that their beloved furry friends will grow up and not be as cuddly as they were in the past.

In this article, you will know the age at which these animals become adults and some signs that will help you identify when this is happening.

At What Age Is a Dog Considered an Adult?

Many people think puppies become adults after one year of age, while others claim that these animals reach that stage at 2 years of age. The truth is that there is no specific age to say that a puppy becomes an adult.

Generally, a puppy can become an adult between 9 months and 3 years of age. This can vary depending on the breed of dog, size, etc.

Many experts say that small breed puppies become adults between 9 months and 12 months of age, but large breed dogs usually reach that stage between 2 and 3 years.

When a Dog Reaches Adulthood According to Its Age?

As we have said before, the age at which a puppy reaches adulthood depends, among other factors, on the breed’s size.

You must know that the larger the breed of dog you have, the longer it will take to reach physical and mental maturity. Although many affirm that dogs become adults at 1-2 years of age, we will tell you below the age at which a canine reaches that stage according to its size:

How Can I Know If My Dog ​​Is Entering the Stage of Adulthood?

Sometimes it is a bit challenging to know the exact moment our dogs reach adulthood, which is even more common among first-time dog owners.

There are several signs that a dog will begin to show when it is becoming an adult. The most common are:

Loss of Baby Teeth

The most common sign when a dog becomes an adult is the loss of milk teeth. Like humans, puppies have milk teeth that progressively begin to fall out until permanent teeth completely supplant them.

Keep in mind that puppies have 28 milk teeth that grow throughout the first 6 weeks of age. From 16 weeks of age of these animals, the milk teeth will begin to fall out little by little giving way to adult teeth.

Sexual Maturity

After the first 6 months of age, male puppies will begin to be attracted to females. At that age, females will begin to enter their first heat cycle. That will cause these animals to mate with the possibility that they will have their first offspring.

When you notice that your male dog approaches a female with certain intentions or that other males surround your female dog, it is clearly a sign that it is sexually maturing and becoming an adult. You will not see this type of behavior in a puppy under 6 months of age.

Lower Energy Level

As you know, puppies have a high energy level, just like children. Young dogs tend to be hyperactive compared to adults, so it is normal to see them always running around, playing, exploring, and exercising.

A puppy will cause disasters throughout the house, whether it is biting shoes, carrying objects from one place to another, eating garbage or rummaging through it, etc.

As the puppies grow, they will show interest in more specific activities, thus reducing their level of hyperactivity. A 1-year-old dog will have slightly less energy than a 6-month-old puppy. The older a dog is, the less hyperactive it will be.

Destructive behaviors are common in puppies due to their high energy level and tendency to get bored easily. It’s essential to keep dogs this age entertained and give them enough exercise to tire them out.

Slight Fur Changes

If you notice some changes in your pet’s coat, then that means it is shedding its new adult coat. Keep in mind that this directly depends on the breed of dog.

Generally, a puppy begins to experience these changes in its coat from 6 months of age, although the coat may continue to develop until 18 months. Everything will depend on the specific breed of dog and the amount of hair it has.

Less Enthusiasm to Eat

All dogs, without exception, love to eat. These animals crave whatever food their owners put in front of them. In fact, some breeds of dogs may consume garbage due to their high desire to eat.

However, dogs will gradually begin to feel less of a need to eat as they age. In fact, that is one of the reasons why these animals (as adults) need two or even one meal per day, unlike puppies, which require three meals per day.
