When Do Chihuahuas Stop Growing? Complete Guide Growth and Weight

Chihuahuas are one of the most popular dog breeds in the United States. They’re small and adorable, but when they get older, Chihuahuas can be very protective. Your Chihuahua is a small, compact little canine when you get it from the breeder or when you adopt a chihuahua.

You may think that he’ll stay this way forever, but when do chihuahuas stop growing? He’ll start to grow until he reaches his full size and weight when he’s about two years old. This growth chart will help you estimate your pup’s adult size and see what normal weights are for Chihuahuas in various age groups.

Chihuahua Growth & Weight Chart Information

Chihuahua growth is a very rapid process, and by the time they reach their first birthday, you’ll notice that your dog has started to slow down when it comes to his weight gain. At this point, he will begin putting on more lean muscle mass instead of fat, which may lead you to think that he’s actually shrinking! This is normal as long as he isn’t losing too much weight during the process. 

It can take up to 18 months for him to be considered fully grown and ready for adulthood. Adult Chihuahuas typically weigh anywhere between 4 pounds (the smallest breeds) all the way up to 10 pounds (for larger standard variations). Females are usually smaller than males when they reach adulthood.

It’s important to note that Chihuahuas are one of the most genetically diverse dogs breeds out there, and different combinations can lead to variations in appearance and weight gain. 

Standard varieties usually weigh between 6 and 10 pounds when fully grown. However, it’s more common for them to fall on either end instead of in the middle of the two extremes, like some other small dogs such as Yorkshire Terriers or Pomeranians.

Chihuahua Growth Chart 

Puppy (Up to 4 Months Old)

When your pup was a baby you may have noticed he weighed anywhere from 2 ounces and 2 pounds when he reached his first month. This rapid weight gain is totally normal. By the time he reaches three months old, he’ll be tripling his weight.

The average Chihuahua weighs somewhere between 4 and 5 pounds when they’re seven weeks old, but this can vary depending on the size of their parents as well as what type you have. If your pup falls outside of these numbers it’s okay! 

Just see how he grows when he reaches adulthood to know if there are any issues with his growth rate or health in general. Most don’t grow at a consistent pace after their first few months.

Adult (8 Months and Up)

A full-grown adult chihuahua is usually anywhere from 3 to 6 pounds when they reach maturity. However, females tend to weigh less than males overall. You may notice when your dog reaches his first birthday that he stops gaining weight so quickly.

During this time if he’s still growing at a healthy pace you may notice changes in the way he looks. He’ll be leaner and more muscular instead of chubby and fluffy! He’ll continue to grow until 18 months when both growth plates have closed up on each side of his body. 

However, some breeds can be considered full-grown as early as 16 weeks or as late as 24 months depending on their size when they hit adulthood. 

Keep an eye out for any issues with Chihuahua growth like stunted development during these periods (he will look smaller than other dogs) and make sure to follow up with your vet right away if something seems off about him or you suspect that there’s a health issue.

How Much Bigger Will My Chihuahua Get?

Your puppy may grow up at a slower pace than other breeds, but they may also end up growing larger in size than you had expected them to be.

  • Averages of adult weight (3 to 7 pounds). Height depends on parents’ sizes.
  • Puppy growth stages: From birth up until one-year-old, puppies typically start off very small before rapidly growing bigger throughout their first year of life.
  • Puppies grow rapidly over a period of time, adult height can vary depending on breed and genetics, and environmental factors.

How Do I Make Sure My Chihuahua is Healthy?

Chihuahuas are small dogs and generally live longer than most other breeds. 

Health complications such as heart disease, breathing problems, and slipped stifles may be seen in some chihuahuas. With proper monitoring of your pup’s weight throughout their life, it’s possible to prevent them from becoming obese or overweight.

This will help you avoid many potential health issues that can arise from obesity including arthritis pain or even diabetes if the excess weight causes a change in blood sugar levels. Make sure to give your dog well-balanced food by feeding him/her high-quality kibble at least twice per day while ensuring he doesn’t get too hungry before his next meal.

You can offer your pup a healthy treat or two in between meals to curb their appetite and make sure they don’t get too hungry before the next meal time approaches. Try to avoid using people’s food as treats since this can lead them to become overweight if they eat too much of it.

Well-balanced food that doesn’t include too much sugar or preservatives will also help to keep your pup’s weight under control. Moreover, high-quality foods, coupled with enough activity (Chihuahuas are great swimmers!) will provide your dog with all of the nutrients that a it needs to stay healthy and won’t leave them feeling hungry since they don’t contain any filler ingredients.

When Do Chihuahuas Stop Growing?

Many Chihuahua owners wonder when their pup will stop growing. The answer is that this varies depending on the individual dog’s breed and genetics, but most dogs don’t complete growth until around one year of age.

It’s also important to note that Chihuahuas may not finish out at a standard weight. As a result, it is important to keep an eye on your pup’s size and weight. If you feel that they are too small or big for their breed standard at any point in time, speak with the vet about appropriate diet changes.

6 Factors That Affect The Growth of Your Chihuahua

1. Nutrition

Is your dog eating healthily? Nutrition is critical in the role of how healthily your Chihuahua grows. 

2. Environment

Being indoors or outdoors can also affect their development, as well as playtime activities. Too much stress from loud noises, and increased or decreased activity can cause excess weight gain or loss.

3. Age

A young Chihuahua will grow faster than an older one. However, there is no way of predicting exactly how much your Chihuahua will grow over their lifetime due to the factors mentioned above! Keeping them at a healthy weight and providing exercise or playtime with other dogs will contribute to a healthy Chihuahua.

4. Genetics

Their breed and parents’ genetics will affect the growth of a Chihuahua. Genetics also play a role in determining their size and weight.

5. Gender

Males are typically larger than females, even when they come from the same litter! Although not very common, some male Chihuahuas may also be smaller or grow at a slower rate compared to other dogs of the same breed. Both males and females should have their growth monitored on a regular basis.

6. Health

If your Chihuahua has excess weight and is not eating healthy, this can indicate a health problem like hypothyroidism. If excess weight gain occurs suddenly or significantly, this can indicate a health problem. If excess weight is accompanied by other symptoms like difficulty breathing, lethargy, etc., this should be checked out immediately by your veterinarian.

Dangers of Stunted or Accelerated Growth in Chihuahuas

An overweight Chihuahua will have joint issues in the future if their weight isn’t controlled over time by diet and exercise. If you notice that they’re unable to walk or run easily, it’s important to go to a vet immediately to get them on a diet plan.

An obese Chihuahua will have liver problems and high cholesterol over time, which can affect its overall health. Moreover, they’ll experience more difficulties breathing, which can make their quality of life poor.

Overweight Chihuahuas are also at risk of getting diabetes, as excess weight increases the blood sugar levels over time and puts them at high risk for this disease. If your dog is diabetic or has other health issues like thyroid problems that could be causing excessive weight gain, it’s important to go to a vet.

Stunted growth in older dogs means they have experienced stunted development due to being overweight, leading them to not mature properly into adult dogs. It’s important to keep an eye on the ideal weight for your Chihuahua and ensure that you are feeding them healthy food in appropriate portions, keeping Chihuahuas active, or playing with other small dogs over time so they maintain their ideal size!

Life Expectancy of Chihuahuas

They can live for up to 18 years, which is longer than most breeds! Although Chihuahuas do not need as much exercise as their size may suggest, it’s still important that they get some type of daily activity. This will help them stay healthy and happy throughout the years.

Along with eating good quality food, you should also consider adding supplements to your chi’s diet, too. The best way to ensure your Chihuahua lives long is to provide them with a healthy and nutritious dog’s diet.

Chihuahuas need to be fed twice a day, and the amount you feed them depends on their age and activity levels. You should also take into consideration their size when feeding Chihuahuas. For example, if they are smaller in size then you may only need to give them half of what an adult Chihuahua eats during each mealtime!


When do chihuahuas stop growing? Chihuahuas will typically stop growing after their first year or two of life. Between the ages of 4 months and 1 year, you’ll see a rapid growth rate that slows as they reach maturity.

As mentioned before, make sure you provide your pups with healthy food at appropriate portions or risk stunted growth from being overweight or unhealthy living habits like eating too much table scraps. It’s important for these little dogs to maintain a good quality of life and healthy diet so that they can grow to be happy and healthy companions and even good service dogs, which may not seem so apparent due to their size.
