Anatomy Of Dog Abdomen

Anatomy Of Dog Abdomen

As dog owners, we are constantly bombarded with adorable pictures of our furry friends on social media, in magazines and online. But what does it really look like underneath their fur? In this article, we will take a look at the anatomy of a dog’s abdomen and explain the differences between it and that of a human’s.

The Digestive System

The digestive system is responsible for breaking down and absorbing food into the body. The system includes the mouth, esophagus, stomach, small and large intestines, and anus.

The mouth is where the dog feeds. The dog’s teeth are specially adapted to tearing apart food. The layers of teeth scrape against each other, breaking down meat into small pieces that can be easily swallowed.

The esophagus is a long tube that carries food from the mouth to the stomach. The esophagus is protected by a tough layer of skin called the epiglottis. This guard prevents food from escaping into the lungs during swallowing.

The stomach is a large, hollow organ located near the spine. The stomach squeezes and mixes foods with some water before sending them on their way to the small and large intestines.

The small intestine is a short tube that moves food through the body quickly. It helps to digest carbohydrates, proteins, and fats.

The large intestine is a long tube that helps to digest excess waste material from the small intestine. It also helps to remove water and minerals from food.

The Liver

The liver is a large, flat, yellowish-white organ located just below the rib cage on either side of the spine. It is responsible for filtering your blood and removing impurities from it. The liver also helps to produce bile, which is used to digest food.

The Pancreas

The pancreas is a small organ located in the upper right portion of the stomach. It is about the size of a thumb and contains two lobes, called the exocrine and endocrine lobes.

The exocrine lobe secretes digestive enzymes and bicarbonate ions into the intestine to help break down food. The endocrine lobe produces hormones that help control digestion and gastric function.

One important hormone produced by the pancreas is insulin, which helps convert sugar into energy for the body. Insulin resistance is a common problem, and diabetes is a result.

The Intestines

The intestines are a series of organs that line the entire length of the digestive system in dogs. They are made up of several sections:

1. The small intestine or small stomach is the first section of the intestines and it’s about 6 to 12 inches (15 to 30 cm) long. It’s located near the stomach and helps to digest food.

2. The large intestine or colon is the next section and is about 15 to 30 inches (38 to 76 cm) long. It’s where waste products are expelled from the body.

3. The rectum is the last section of the intestines and it’s about 4 to 6 inches (10 to 15 cm) long. It’s where waste products are stored until they’re eliminated through defecation.

The Spleen

The spleen is a small organ found tucked away under the left side of the ribcage in dogs. It is usually tranquil, but can become active in response to infection or inflammation.

The spleen is responsible for destroying old red blood cells, damaged tissue and foreign bodies that have entered the body through the bloodstream. This process helps to keep the body’s immune system functioning properly.

In addition to helping to protect the body against infection, the spleen also plays an important role in regulating blood sugar levels. When food is metabolized, it breaks down into glucose and other nutrients which are then distributed throughout the body. The spleen helps to control how much glucose is produced by the liver and sent to other parts of the body.

The Kidneys

The kidneys are two bean-sized organs located on either side of the spine just below the ribcage. They filter waste products from the blood and produce urine.

The kidneys are responsible for controlling blood pressure, maintaining fluid balance, and regulating the body’s electrolytes. When they start to fail, these vital functions can become compromised, leading to kidney disease.

There are several signs that your dog may be suffering from kidney disease, including difficulty getting up after lying down, increased thirst or urination, weight loss, poor appetite, and vomiting. If you notice any of these symptoms in your dog, please consult with your veterinarian.

The Bladder

The bladder is a muscular, sac-like organ located in the abdominal cavity of dogs and other animals. It stores urine until it can be emptied through the urethra. Dogs and other animals use their bladders to regulate their body temperature.

The Blood Vessels

The first blood vessels in the dog’s abdomen are the vena cava and the aorta. From here, blood flows to all of the organs in the dog’s abdominal cavity. The second set of blood vessels is called the iliac arteries. They originate from the vena cava and divide into two branches, which go to each side of the dog’s abdomen. The third set of vessels are called the inferior vena cava. These originate from a branch of the iliac artery and flow under the skin to join up with other veins near the dog’s groin.


We looked at the anatomy of the dog abdomen. This will include a brief description of each section and its function, as well as some common ailments that can affect this area. We’ll also give you some tips on how to identify and treat these problems. Finally, we’ll provide a few examples to show you just how detailed the information in this article can be. So if you’re ever concerned about your dog’s abdominal health, take a look here first!
