How Big is a Chihuahua Stomach?

How Big is a Chihuahua Stomach?

They say if you want to know the size of a person’s stomach, you should measure the size of their fist.

So, what do you look at when you want to know the size of a Chihuahua’s stomach?

Unfortunately, we don’t have a specific answer to this question as the size of a Chihuahua’s stomach doesn’t depend on a single body part.

But being a small dog breed, it is pretty obvious that their stomachs are smaller compared to other large dog breeds.

What Determines the Size of a Chihuahua’s Stomach?

The size of a Chihuahua’s stomach will depend on various factors, such as body size, weight, and age.

When looking at the body size of a Chihuahua, three things to consider are the length, the chest girth, and the neck.

A small Chihuahua will have a length of 9-9.5 inches, a chest girth of 12-14 inches, and a neck length of 8-9 inches.

On the other hand, a large Chihuahua will have a length of 10.5-11 inches, a chest girth of 15-17 inches, and a neck length of 10-10.5 inches.

As is expected, a small Chihuahua will have a small stomach (and vice versa).

Regarding the weight, a small Chihuahua will weigh between 2.5-3.5 pounds while a large one will weigh between 7-8 pounds.

There are some extra-large Chihuahuas whose weight can go up to 12 pounds, but they are not as common.

The more weight a Chihuahua has, the bigger the stomach is (and vice versa).

And the big stomachs in large Chihuahuas help them to eat more so they can maintain their weight.

An aged Chihuahua will also have a slightly bigger stomach compared to a puppy.

Until the puppy is five months old, the stomach keeps on growing, allowing them to eat more food, and this is important for its physical development.

How Much Should You Feed Your Chihuahua

It is important to know the right amount of food to feed your Chihuahua.

Feeding him too much food can make him obese while not giving him enough food can make him nutrient-deficient, causing a host of health problems.

Due to their small body size, Chihuahuas are more prone to become overweight than underweight.

A. Feeding a Puppy Chihuahua

Since puppies are at a stage where their joints and bones are developing, they need to eat more food compared to adults.

Additionally, the food you give to your puppy should be high-quality with a +22.5% protein content.

The type of Chihuahua puppy you own also matters. Smaller-sized Chihuahuas tend to consume less amount of food compared to their larger counterparts, so the amount of food that your puppy will need will depend on his individual size.

Your puppy’s age will also influence the amount of food to feed and the feeding frequency or schedule.

Here is a rough feeding guideline that you can adopt:

  • For 2-4 months puppies: Feed around 4-6 meals a day
  • For 4-8 months puppies: Feed around 3-4 meals a day
  • For 8+ months puppies: Feed around 2-3 meals a day

Finally, factors like the weight and activity level of the puppy should also dictate the amount of food that you feed your puppy.

Still confused? Well, always err on the side of caution when it comes to the right amount of food to feed your puppy as you don’t want him to become obese during his prime developmental stage.

B. Feeding Adult Chihuahuas

The amount of food to feed an adult Chihuahua depends on his specific calorie requirements, which tend to fluctuate daily and often depend on the weight, age, health status of the dog, and sometimes weather (your pup may consume more food in the winter).

So, before deciding on the amount of food to feed an adult Chihuahua, you need to first ascertain their ideal weight, exact age, and health status.

You can always consult your vet for these parameters. You can also check a veterinary weight chart to know your dog’s ideal weight.

Your dog’s current weight, age, and health status will determine whether you’ll give them more food or less to achieve the ideal, healthy weight.

Generally, Chihuahuas that weigh 4-10 pounds will consume about 0.5 to 1.3 cups per day—which should be split into 3 or more meals.

(In fact, if your Chihuahua suffers from hypoglycemia and other food-related conditions, consider breaking his feeding times into even more meals).

Few Chihuahuas will eat more than 2 cups per day but those that do tend to be bigger than the standard breed size.

Another thing to consider is your Chihuahua’s activity level. A highly active dog may need more food compared to a sedentary (or elderly) one depending on their rates of metabolism.


A sudden change in appetite could be a sign of an underlying health issue.

So, if your Chihuahua isn’t eating the way he used or his appetite reduces to an extent that he is losing weight, you should consider taking him to the vet for more professional advice.


So, how big is a Chihuahua stomach?  

Well, it is difficult to say for sure how big or small a Chihuahua’s stomach is.

But, if you’re comparing them to other large dog breeds, their stomachs are quite small.

As shown in this post, the size of a Chihuahua’s stomach will depend on its body size, weight, and age.

On the same note, the amount of food you give to a Chihuahua will depend on their age, weight, and activity level.

And always remember that Chihuahuas excel in begging. So, never give in to their begging eyes if you seriously want to help them maintain a healthy weight.
