Chihuahua Growth Chart (Weight Chart & Size Chart)

What size will my Chihuahua puppy grow to be? When will my Chihuahua stop growing? These are the questions that almost every Chi owner wants to know the answers to!

This breed's growth can be a little erratic. As a result, the smallest pup in the litter may wind up outgrowing his littermates by the time they reach the one-year milestone.

The easiest method to predict how big a Chihuahua will grow up to be is to check at his lineage. Size, as well as other physical characteristics, are inherited. The dam and sire's genes will undoubtedly influence a Chihuahua's size; however, checking three generations back will give you the best notion of the size that runs in the family.

When Do Chihuahuas Stop Growing?

Given that Chihuahuas do not get very large, you may be wondering how you can determine when a Chihuahua has achieved his or her appropriate size.

They may not develop as quickly as huge breed dogs, but they will grow steadily.

Your puppy will gain a few ounces per week as he grows. Reaching roughly 20 weeks, or 5 months, he should be at his final size.

He may gain a little more weight after that, but your dog will not become much larger than he is now, even though he is still a puppy.

Chihuahua Weight Calculator

If you only know your Chihuahua's weight in pounds, you can convert ounces to pounds using the following formula:

The number of solid pounds multiplied by 16 + the percentage of pounds

For example, if a dog weighs 1.2 pounds, the calculation is 1 x 16 + 2 = 18 ounces.

In other terms, multiply 1 (the number of solid pounds of the puppy) by 16 (the number of ounces in a pound) + 2 (the result of the.

2 in terms of the pup's weight)

Another example: For a 2.1-pound dog, the formula would be: 2 x 16 Plus 1 = 33 ounces.

In other terms, 2 (the puppy's solid pounds) x 16 (the number of ounces in a pound) + 1 (the amount gained from the.1 in the pup's weight)

Chihuahua Growth Chart – What To Expect
Chihuahua Weight Chart by Age

Chihuahua Weight  1-2 weeks

Newborn Chihuahua puppies are small enough to fit inside the palm of your hand, weighing an average of 212 to 512 ounces and measuring 3 to 4 inches in length. They will, however, grow fast during their first few weeks, frequently doubling in size while adding 5-10% of their body weight every day.

Chihuahua Weight 3-12 weeks

Between the ages of 3 and 12 weeks, your Chihuahua puppy will continue to grow rapidly. The first month is when your puppy will grow the fastest.

After that, your puppy should continue to grow steadily, but there may be times when he gains quickly and then plateaus for a while. However, a weight increase is expected.

Chihuahua Weight 4-6 months

A 6-month-old Chihuahua will be close to their full height, usually between five and eight inches tall, and will have gained the majority of their adult weight, weighing between 1.5 and 4.5 pounds depending on their predicted adult size. According to the Chihuahua growth and weight chart above, your Chihuahua should gain another half pound to pound and a half.

Chihuahua Weight  7-9 months

Your puppy's growth should decelerate between the ages of 4 and 9 months. Some Chihuahuas will stop growing during this time and will merely gain weight as they reach adulthood. Other Chihuahuas may not reach full size until they are a year old.

Chihuahua Weight  10-12 months

Chihuahuas, like most toy breeds, reach maturity and cease growing by 10 to 12 months. However, the weight of your Chihuahua will change according to his nutrition, health, and amount of physical activity.

Chihuahua Adult Weight 

A healthy mature Chihuahua should weigh between 2 and 7 pounds, depending on the dog's gender and height. A full-bred Chihuahua should weigh no more than 7 pounds. Your older Chihuahua should still be energetic and require plenty of exercises.

What is the Full Grown Chihuahua Weight?

A Chihuahua should not weigh more than six pounds and should be five to eight inches tall, according to the American Kennel Club's Chihuahua Standard. A Chihuahua can weigh as little as two pounds and as much as six pounds, while there may be subtle discrepancies in genetics and environmental variables that influence their overall size. Chihuahuas should be well-balanced, with a body that is somewhat longer than tall.

How To Weigh Your Chihuahua Puppy?

This would be a little easier if your Chihuahua is little enough to fit on your bathroom scale. If not, it may become more difficult, but it is not impossible.

All you have to do is weigh yourself on a bathroom scale and keep track of your weight. Then, while holding your Chihuahua, make sure he is over the scale so that an accurate measurement may be taken.

Simply subtract your weight from the total weight of you and your Chihuahua to get the weight of your Chihuahua.

What Is A Chihuahua’s Neck Size?

To determine the neck size of your dog, use a soft and flexible tape measure to determine the neck size of your dog where her collar naturally falls. Then, put two fingers between your dog's neck and the tape measure to ensure that the dog collar fits snugly but comfortably. Basenji's average neck circumference is between 22 and 30 centimeters.

How Big Do Chihuahuas Get?

A Chihuahua's growth will be completed around the age of nine months. They may continue to gain a little weight between the ages of 10 months and one year, but this weight should not be significant. If your Chihuahua is more than nine months old, he or she is probably at full size or close to it.

The paws of a puppy might suggest whether or not it needs to develop more. Examine your Chihuahua's paws to see if they appear huge in comparison to their legs and torso. If their paws appear a little large, they may still be growing into them.

Furthermore, if you got your Chihuahua from a breeder, you can inquire about your pup's expected mature size. Based on prior litters of puppies and the size of your Chihuahua's parents, your breeder should be able to tell you an exact figure.


Factors That Affect Chihuahua Puppy Growth 


Genetics, including the type of genes present and how those genes interact with one another, is the single most influential element in determining a Chihuahua puppy's pace of growth and subsequent adult size. Because parents and their offspring often have the same DNA, growth charts are based on this.

Growth hormone levels in a Chihuahua puppy will influence his development. If a puppy's pituitary gland does not create enough of this important hormone, he may grow more slowly and become a smaller adult.

Diet & Nutrition

Chihuahua puppies should get all of the nutrients they need from their mother's milk, including protein, amino acids, fatty acids, calcium, sugar, and phosphorus. However, once they've stopped drinking milk, they'll want a well-balanced diet to promote healthy growth and development. If a puppy's food lacks the proper sort and ratio of nutrients, he will grow more slowly.

Physical Activity & Health

While frequent activity is important for establishing strength and strong bones, too much can hinder the growth of a Chihuahua puppy. Leg bones in puppies develop from soft patches of underdeveloped bone known as growth plates (also known as epiphyseal plates). Excessive or intense physical activity can fracture these delicate structures, causing them to cease growing or grow wrongly.

In addition, the existence of sickness and underlying health concerns can also have an impact on the growth of a Chihuahua puppy. In the pup's intestinal tract, parasites such as roundworms, whipworms, and hookworms live, limiting the pup's nutrient intake and growth.

Common Questions about Chihuahua

At What Age Is A Chihuahua Fully Grown?

Chihuahuas grow swiftly during their first few weeks of life, frequently tripling in size. Chihuahuas, like many other toy dog breeds, will normally reach full adult height and most of their adult weight within nine months. Any excessive weight increase after nine months may be due to overfeeding or other health issues and should be discussed with your pet's veterinarian.

A Chihuahua will attain the majority of its adult weight by twenty weeks and will continue to fill out to its full adult size by nine months of age, as illustrated in the growth chart above.

Main Types and Breeds Of Chihuahuas

Smooth-Coat Chihuahua: The most prevalent type of Chihuahua and what most people envision when they hear the word “Chihuahua.” Short coats are low-maintenance and available in a variety of colors.

Long-Coat Chihuahua: The fur on this variety of Chihuahua is soft. Brushing on a daily basis is recommended for this breed of dog, as they are a little high maintenance.

Apple Head Chihuahua: This breed of Chihuahua was named from the shape of his head. They can have hydrocephalus, which contributes to their large head size.

Deer Head Chihuahuas have longer legs than other Chihuahua breeds. They are not seen at dog shows and do not make good display dogs. They are also extremely beneficial to the breed.

Teacup Chihuahua: This is the smallest variety of Chihuahua and is a little dog. Despite their diminutive size, they behave and look like larger Chihuahuas. They are prone to a wide range of health problems, so be prepared.

Hairless Chihuahua: Despite the fact that they are named Chihuahuas, these are not your typical Chihuahuas. As a result of overbreeding, they have lost their hair.

Fawn Chihuahua: This is not a specific breed, but rather a coloring that can be found in many different sorts of Chihuahuas.

How Long Are Chihuahuas Pregnant?

How long is a chihuahua pregnant?
How long is a chihuahua pregnant?

Chihuahuas are pregnant for the same period of time as other dogs, which is approximately 63 days, or 9 weeks. The date is calculated from the dog's ovulation cycle until the birth of the puppy. They, like humans, have three trimesters, but each one lasts around 21 days.

Chihuahuas can also become pregnant by much larger canines, which can be quite harmful to the Chihuahua. Keep your female Chihuahua near when she is in heat or have her spayed to prevent her from becoming pregnant.

Your dog will be clearly pregnant 2-3 weeks after conception, but the puppies will not be seen on an x-ray for up to 45 days.

How Many Puppies Do Chihuahuas Have?

Because Chihuahuas are not huge dogs, they are unlikely to have large litters of puppies. A Chihuahua litter typically consists of one to three puppies, however, it is possible to produce up to six babies depending on the breed.

Generally, the smaller the dog, the fewer puppies it will have at one time. This is also why it is critical not to breed your female Chihuahua with a lab, as labs typically have more babies, which would be too huge for her body.

It is also critical that your dog does not become pregnant during her first heat cycle.

What Is The Life Expectancy Of Chihuahuas?

Chihuahuas, fortunately, have a longer life expectancy than large breed dogs. A Chihuahua can live up to 20 years if properly cared for, however, you can anticipate your dog to live anywhere between 12 and 20 years if properly cared for.

Your dog's life expectancy is influenced by his health and whether he has any underlying illnesses that could shorten his life. There is also the attention and nutrition that the dog has gotten.

How Much Does It Cost To Own A Chihuahua?

The cost of owning a Chihuahua is determined by a number of factors. Because it is a popular breed, you should be able to find one for less than $1000.

They can be found for a few hundred dollars at shelters around North America. Purebred Chihuahuas purchased from breeders will be significantly more expensive, so consider whether having a purebred is actually important to you.

Food, which should be inexpensive for a little dog, training, and veterinarian bills for annual and incidental examinations will be additional costs. You must also consider the cost of a dog license, which varies by location.

How To Help Your Chihuahua Lose Weight If He Is Overweight 

As with humans, exercise is critical for your overweight dog's health. Increased movement helps your dog burn off excess energy (and calories consumed). Avoid panic! Exercising your pet does not have to include marathons or lengthy hikes. Regular walks and the opportunity to run and play safely off-leash. Even creating a stimulating indoor environment that encourages your dog to exercise on a regular basis can help. Bear in mind that different breeds require varying amounts of exercise, so visit your veterinarian, breeder, or your dog's breed standard for recommendations on recommended activity levels.

Distinguish Begging from Hunger

Begging is not necessarily motivated by a desire for more food; it is also used to gain attention. (And, by rewarding the behavior, you reinforce and encourage it to continue.) If your dog begs, do not automatically assume he is hungry. Trust your instincts and keep track of the date and time of your last meal. If your dog is prone to begging and you are prone to succumb to those puppy dog eyes, choose a high-protein meal with a fiber blend to help control your dog's hunger and voluntary food consumption. In this manner, you may feed your dog with the assurance that he will feel fuller and content for a longer period of time.

Restriction on treats and table scraps

Even when our dogs are not begging, many of us provide an excessive amount of treats and table scraps. Dogs are not required to share our food! Consider treats and scraps for your pet in the same way that you would candy for children to help you keep them in check. If you're going to utilize snacks for training, choose low-calorie, low-fat ones and keep the portions small.

As an alternative, keep in mind that clickers are excellent for reinforcement… and they have no calories! After all, a few extra pounds can make a significant impact in the lives of dogs, which are significantly smaller than humans. (Even the colossal breeds!) Therefore, focus on a balanced diet and resist the temptation to “reward” them with extra.

Customize Your Dog's Diet

Not all weight-loss foods are created equal, which is why it's critical to match your dog's nutrition plan to their unique needs. Choose a brand that caters to your dog's unique needs, whether they be weight control, dietary sensitivities, or illnesses.

Frequently Asked Questions:

How do I predict the size of my Chihuahua?

Professionals say that measuring your dog at six months old will allow you to “guesstimate” its future height. Multiply the number by 100 and divide the result by 75. For example, a six-month-old puppy measuring 4.5 inches (11 cm) will grow to be 6 inches (15 cm) as an adult.

Are weight charts for Chihuahuas accurate?

There is a way for estimating the weight of a Chihuahua puppy after it is completely grown. This is accomplished using a weight chart. Of course, they are only approximations. This reference chart, on the other hand, is frequently accurate to within 1/2 pound.

How can I know whether my Chihuahua is a purebred?

Because chihuahuas are classed in two ways, determining the sort of chihuahua you have is simple. One way to tell them apart is by the shape of their heads, which can be either apple-shaped or deer-shaped; the other way is by the texture of their coat, which can be long-haired or smooth.
