Chihuahua Guide: How Long Does It Take a Chihuahua to Digest Food

Do you have a chihuahua that is always hungry? If so, you may be wondering how long does it take a chihuahua to digest food. It can be challenging to answer because there is no one-size-fits-all answer. In this blog post, we will discuss the factors that play into how long a chihuahua takes to digest food. We will also provide some tips on how you can help your Chihuahua to digest food more efficiently.

The Chihuahua Digestive System

The Chihuahua is a small dog known for its large eyes and tiny stature. But did you know that the Chihuahua also has a unique digestive system? For one thing, the Chihuahua’s stomach is much smaller in proportion to their body size than other dogs. Thus, they are more susceptible to gastrointestinal issues such as indigestion, bloating, and diarrhea.

The Chihuahua’s intestines are shorter and less convoluted than other dogs. It makes them more efficient at absorbing nutrients and more vulnerable to intestinal blockages.

How Long Does It Take a Chihuahua to Digest Food: Factors to Consider

After a nice meal, most of us are content to spend a few hours digesting before getting up and going about our day. But for some small breeds of dogs, the digestive process can take a bit longer. Chihuahuas fall into this category, with a digestion time that averages 4-6 hours from start to finish. It is partly due to their small size, which means they have a smaller surface area available for efficient nutrient absorption.

In addition, the transit time of food through the intestines is generally slower in dogs than in other animals. However, there are some individual differences, so some Chihuahuas may be able to digest their food more quickly than others.

Furthermore, several factors play into how long it takes a chihuahua to digest food. These include:

🐕The Size and Breed of the Chihuahua

The size and breed of a chihuahua affect the time it takes for the Chihuahua to digest food. More miniature chihuahuas have a faster metabolism and can digest food quicker. Toy and teacup chihuahuas are even smaller and have an even faster metabolism.

Larger chihuahuas, such as standard or grande, have a slower metabolism and digest food at a slower rate. Long-haired chihuahuas also have a slower metabolism due to the extra hair around their digestive tract.

🐕The Amount of Food

The amount of food that a chihuahua eats in one sitting will affect how long it takes for a chihuahua to digest food. If a chihuahua eats a large meal, it will take longer for the food to be broken down and absorbed into the bloodstream.

However, if a chihuahua eats several small meals throughout the day, it will digest food more quickly. The recommended amount of food for a chihuahua will vary depending on its age, weight, and activity level. However, most experts recommend feeding chihuahuas 3-4 small meals daily.

🐕The Type of Food

Chihuahuas are notorious for being picky eaters, but the truth is that they just have sensitive stomachs. That means the food they eat can significantly impact their digestion. For example, high-fat foods can be hard to digest, and foods high in fiber can cause constipation.

As a result, it’s essential to feed your Chihuahua a balanced diet that includes both wet and dry food. Wet food is easier to digest, and dry food helps keep their digestive system healthy. You should also avoid feeding your chihuahua table scraps, as this can upset their stomach and cause indigestion.

🐕The Age of the Chihuahua

The average longevity of chihuahuas is 15 years, making them one of the breeds of dogs with the longest life spans. However, this doesn’t mean they don’t experience age-related changes as they age. The length of time it takes a Chihuahua to digest food is one of the most noticeable changes. As puppies, chihuahuas have a very high metabolism and can digest their food in as little as 30 minutes.

However, by the time they reach old age, their metabolism has slowed, and it can take up to 6 hours to fully digest a meal. This change is due to the reduction in muscle mass and kidney function with age. While it’s not necessarily a health concern, it’s something that owners should be aware of so they can adjust their dog’s feeding schedule accordingly.

🐕The Exercises of the Chihuahua

Food digestion uses up a lot of energy, and activity can quickly deplete energy stores. As a result, it’s best to wait at least an hour after the Chihuahua digest food before taking them for a walk or allowing them to play.

However, this advice is specifically for larger breeds of dogs; small dogs like chihuahuas have a much higher metabolism and digest food much more quickly. As a result, chihuahuas can exercise immediately after eating without any negative impact on their digestion. Exercise is beneficial for chihuahuas after they’ve eaten, as it helps them move food through their digestive system more quickly.

🐕The Chihuahua Health Condition

Some chihuahuas suffer from health problems that make it difficult to digest food properly. For example, a condition called megaesophagus occurs when the muscles in the esophagus fail to contract properly, causing food to become stuck in the throat. It can lead to regurgitation and weight loss. In severe cases, megaesophagus can be fatal.

Another condition that can affect chihuahua digestion is pancreatitis, inflammation of the pancreas. It can cause pain, vomiting, and diarrhea. If your Chihuahua is suffering from either of these conditions, it’s essential to work with a veterinarian to develop a plan to help them stay healthy and maximize their quality of life.

👉Mastication or Chewing

Mastication, or chewing, is the first part of Chihuahua digestion. Saliva, which contains enzymes that aid in the breakdown of carbohydrates and the start of the digestive process, greets food as it enters the mouth. The teeth grind the food into smaller pieces for easy digestion.

The act of chewing also helps to release more saliva, further aiding in the breakdown of carbohydrates. After chewing, the food travels down the esophagus and into the stomach, which will undergo further digestion.

👉Deglutition or Swallowing

Deglutition, also known as swallowing, is an integral part of Chihuahua digestion. When a Chihuahua ingests food, the process of deglutition begins. The Chihuahua’s mouth and throat muscles cooperate to transfer food from the mouth into the stomach. Once in the stomach, stomach acids and enzymes break down the food.

The process of deglutition is vital to a Chihuahua’s health, as it helps to prevent choking and ensure that nutrients are properly absorbed.

👉Gastric Emptying

It empties the food and liquids from the stomach into the small intestine. In dogs, gastric emptying occurs relatively slowly, but in Chihuahuas, it occurs much more rapidly. As a result, Chihuahuas can digest their food more quickly and efficiently than other dogs.

This ability to empty their stomachs quickly allows Chihuahuas to tolerate changes in their diet better and to absorb nutrients more effectively.

👉The Small Intestine

The small intestine, a long, coiling tube, is in charge of the last phases of digestion. The small intestine is in charge of both waste removal and systemic absorption of nutrients.

There are three portions of the small intestine:

  • Duodenum: The duodenum is the shortest section, and it is where most of the digestion takes place.
  • Jejunum: The jejunum and ileum are longer and absorb most of the nutrients from the food.
  • Ileum: The ileum also absorbs water from the digestive process.

The Chihuahua’s small intestine is about 6 feet long and winds through the abdomen several times. The small intestine also absorbs vitamins and minerals from the food. The waste products from digestion, such as undigested food and bacteria, are passed into the large intestine.

👉The Large Intestine

Chihuahua digestion ends in the large intestine. In this stage, the intestine absorbs water and electrolytes from the indigestible food matter, which helps to solidify the feces. The intestine also houses many bacteria, which help break down the food matter and produce vitamins that are essential for the dog’s health.

The large intestine is significantly shorter than the small intestine, and it is essential to note that this is not a cause for concern. Chihuahuas have a very efficient digestive system and can extract all the nutrients they need from their food without any problems.

Defecation is the process of eliminating solid waste from the body. In Chihuahuas, defecation occurs when the rectum is full, and the dog feels the urge to defecate. When this happens, the anal sphincter of the dog contracts and relaxes, enabling the feces to pass.

It is important to note that defecation is voluntary, and Chihuahuas can control when they defecate. However, if a Chihuahua does not defecate regularly, it can lead to constipation.

Foods That Are Easy to Digest for Chihuahuas

When it comes to feeding your Chihuahua, you want to give them food that is easy to digest. Chihuahuas are small dogs with delicate stomachs, so they need food that is nutrient-rich and easy on their digestive system. Some good options include:

  • Wet food: Wet food is softer and easier to break down than dry food, making it simpler for your Chihuahua’s stomach to process. In addition, wet food often contains more moisture, which can help keep your Chihuahua hydrated and prevent constipation.
  • Canned pumpkin: A canned pumpkin is an excellent option for dogs with sensitive stomachs. It’s packed with nutrients like fiber and beta-carotene and easy on the digestive system.
  • Chicken: Chicken is an excellent choice for Chihuahuas because it is a lean protein source that is easy to digest. Plus, chicken is a good source of essential vitamins and minerals to help keep your Chihuahua healthy. When selecting chicken as a portion of food for your Chihuahua, be sure to choose lean cuts with no skin or bones.
  • White rice: Rice is a complex carbohydrate that can break down into simple sugars during digestion. It makes it an ideal food for chihuahuas because it provides them with the energy they need without putting strain on their digestive system. In addition, rice is a good source of vitamins and minerals, making it a well-rounded addition to a chihuahua’s diet. When feeding your Chihuahua white rice, cook it thoroughly to reduce the risk of indigestion.
  • Bananas: This popular fruit is a good source of fiber, which helps to keep the digestive system running smoothly. Bananas are also rich in potassium, which aids in maintaining adequate fluid balance in the body. They also have essential vitamins and minerals like vitamin C, B6, and magnesium. When feeding bananas to Chihuahuas, it is important to choose ripe fruits that are soft and easy to chew. 
  • Green beans: Green beans are a highly digestible food for Chihuahuas. They are high in nutrients and fiber, which aids in the healthy functioning of your dog’s digestive tract. Green beans are relatively low in calories, making them an ideal weight-loss option for dogs. In addition, green beans are an excellent source of antioxidants, which can help to protect your dog’s cells from damage.

Common Digestive Problems in Chihuahuas

Although most chihuahuas have no trouble digesting their food, some suffer from digestive problems. Some common digestive problems in chihuahuas include:


Bloat happens when the stomach becomes overly full of gas, causing it to expand and pressure the surrounding organs. It can be excruciating for dogs and even fatal if not treated promptly.

Chihuahuas are prone to bloat because of their long, slender bodies and deep chests. You may help prevent bloat in your Chihuahua by giving smaller meals more frequently, avoiding intense exercise after eating and maintaining your dog’s healthy weight.


Constipation occurs when the dog cannot have a bowel movement or has difficulty passing stool. It may be due to a lot of factors, including a lack of fiber in the diet or dehydration. If left ignored, constipation could lead to more severe problems, such as hemorrhoids or anal fissures.

Treatment for constipation typically involves increasing the amount of fiber in the diet and ensuring adequate hydration. In severe cases, laxatives or enemas may be necessary.


Diarrhea is a common digestive problem in Chihuahuas. It may be because of several factors, including an imbalance of gut bacteria, food allergies, or intolerances. While diarrhea can be unpleasant for both dog and owner, it is usually not serious and will resolve itself within a few days.

However, if your dog has recurrent diarrhea or other signs of sickness, you should immediately see your veterinarian. They will be able to determine the underlying cause of diarrhea and prescribe the appropriate treatment.

📌Gastroesophageal Reflux

A weak or injured sphincter muscle between the stomach and esophagus causes gastroesophageal reflux disease or GERD. It permits stomach acid to reflux into the esophagus, resulting in discomfort and inflammation.

Symptoms of GERD include regurgitation, vomiting, and difficulty swallowing. If left untreated, GERD can lead to serious health problems, including weight loss, malnutrition, and even death. While there is no cure for GERD, several treatments can help control the symptoms and keep your Chihuahua healthy.

📌Intestinal Blockage

A foreign object trapped in the intestines or ingesting something too large or difficult to digest can cause intestinal obstruction. If left untreated, an intestinal blockage can be fatal.

In some circumstances, medical treatment can clear the blockage, but in severe cases, surgery may be necessary to remove the obstruction. Intestinal obstructions are a severe health concern for Chihuahuas, so be aware of the symptoms and seek treatment as soon as your dog exhibits indications of suffering.
