Abdominal Ultrasound for Dogs and Cats:
Why It Matters for Your Pet’s Health
When your dog or cat isn't feeling well, finding the cause of their symptoms is the first step toward helping them feel better. Unfortunately, many health problems affecting pets develop inside the body, where they cannot be seen during a routine physical examination. That's where a veterinary abdominal ultrasound can make a difference.
At
Edgewater Animal Hospital, we offer abdominal ultrasound services to help evaluate your pet’s internal organs, investigate concerning symptoms, and support accurate diagnosis and treatment planning. This noninvasive diagnostic imaging tool allows our veterinary team to look inside your pet’s abdomen and gather important information about their health.
Whether your pet is experiencing vomiting, changes in appetite, unexplained weight loss, or other concerning symptoms, an abdominal ultrasound may help us uncover the underlying cause.
What is Abdominal Ultrasound?
An abdominal ultrasound is a diagnostic imaging procedure that uses high-frequency sound waves to create real-time images of the organs and soft tissues inside your pet’s abdomen.
Unlike X-rays, which are particularly useful for evaluating bones and certain other structures, ultrasound allows veterinarians to examine the appearance, size, shape, and internal structure of many abdominal organs in greater detail.
During a veterinary abdominal ultrasound, we can evaluate organs and structures such as:
- Liver: Assess the liver’s appearance and look for abnormalities, masses, or changes that may require further investigation.
- Gallbladder and bile ducts: Look for gallbladder abnormalities, gallstones, and signs of bile flow obstruction.
- Spleen: Evaluate changes in size, tissue appearance, and the presence of masses or other abnormalities.
- Kidneys: Identify structural changes, cysts, certain stones, and other abnormalities affecting the kidneys.
- Urinary bladder: Look for bladder stones, masses, wall thickening, and other changes.
- Stomach and intestines: Examine the gastrointestinal tract for wall thickening, abnormal structures, some foreign objects, and signs that may be associated with digestive disease.
- Pancreas: Look for changes that may support a diagnosis of pancreatitis or another pancreatic condition.
- Adrenal glands: Evaluate the size and shape.
- Abdominal lymph nodes: Evaluate enlarged or otherwise abnormal lymph nodes.
- Abdominal cavity: Identify free fluid, certain masses, and other abnormalities within the abdomen.
The exact structures that can be assessed depend on your pet’s condition, the quality of the images, and the specific area being examined.
Why is Abdominal Ultrasound Important for Dogs and Cats?
Pets cannot tell us exactly where they hurt or how they feel. Sometimes, the first signs of illness are subtle, and routine bloodwork or a physical examination may not provide a complete answer.
An abdominal ultrasound gives veterinarians another way to investigate internal abnormalities and better understand what may be causing your pet’s symptoms.
1. Investigating Vomiting, Diarrhea, and Digestive Problems
Occasional digestive upset can have many causes, but persistent or recurrent vomiting, diarrhea, loss of appetite, or abdominal discomfort may indicate a more serious problem.
An abdominal ultrasound can help evaluate the stomach, intestines, pancreas, liver, and surrounding structures for changes associated with gastrointestinal inflammation, pancreatitis, intestinal masses, and certain foreign objects.
Ultrasound findings are interpreted alongside your pet’s history, examination, laboratory results, and other diagnostic tests to help determine the next steps.
2. Detecting Masses and Abnormal Growths
Abdominal ultrasound is an important tool for identifying masses or abnormal tissue growth involving organs such as the liver, spleen, kidneys, and gastrointestinal tract.
These findings may be associated with benign conditions, cancer, inflammation, or other diseases. Ultrasound can help veterinarians determine a mass’s location, size, and appearance and assess whether additional testing is needed.
However, ultrasound alone cannot always determine whether a mass is cancerous. A fine-needle sample, biopsy, or other diagnostic procedure may be recommended to establish a definitive diagnosis.
Early investigation of suspicious findings can help your veterinary team make informed decisions about further testing and treatment.
3. Evaluating Kidney and Urinary Tract Conditions
Kidney and urinary tract problems can affect pets of all ages. Signs may include increased thirst, frequent urination, difficulty urinating, blood in the urine, or changes in appetite and energy levels.
An abdominal ultrasound can help identify structural changes in the kidneys and urinary bladder, including certain stones, cysts, masses, and abnormalities that may be associated with kidney disease or urinary obstruction.
Ultrasound does not replace bloodwork or urinalysis, but it provides valuable additional information about the structure of the urinary system.
4. Helping Investigate Liver and Pancreatic Disease
The liver and pancreas play essential roles in digestion, metabolism, and overall health.
Changes involving these organs may cause symptoms such as vomiting, lethargy, poor appetite, abdominal discomfort, or weight loss. An abdominal ultrasound can help identify changes in liver tissue, gallbladder abnormalities, and pancreatic changes that may be associated with conditions such as pancreatitis or liver disease.
Because some diseases do not produce obvious ultrasound changes, imaging results should always be considered alongside laboratory testing and your pet’s clinical signs.
5. Finding Fluid or Other Abnormalities Inside the Abdomen
Fluid accumulation inside the abdominal cavity can occur for several reasons, including inflammation, bleeding, certain heart or liver conditions, and some cancers.
An abdominal ultrasound can help detect and locate this fluid, evaluate surrounding organs, and guide decisions about additional diagnostic testing. In appropriate cases, ultrasound can also help veterinarians collect fluid or obtain tissue samples for further evaluation.
Identifying these abnormalities can be especially important when a pet has a swollen abdomen, weakness, pale gums, or other signs of serious illness.
Is an Abdominal Ultrasound Safe for Pets?
Yes. Abdominal ultrasound is generally considered a very safe, noninvasive diagnostic imaging procedure for dogs and cats.
Unlike X-rays and CT scans, ultrasound does not use radiation. Instead, it uses sound waves to create images of your pet’s internal organs.
Most abdominal ultrasounds do not require sedation or general anesthesia. Many pets can remain awake throughout the examination, although some may need gentle restraint or mild sedation if they are anxious, uncomfortable, or unable to remain still.
The procedure is generally painless. Your pet may experience mild pressure from the ultrasound probe against the abdomen, but the examination itself should not cause significant discomfort.
Your veterinarian will determine the most appropriate approach based on your pet’s temperament, medical condition, and individual needs.
What Happens During a Veterinary Abdominal Ultrasound?
If your pet needs an abdominal ultrasound at Edgewater Animal Hospital, the process typically involves several steps.
1. Reviewing your pet’s symptoms and medical history
Our veterinary team will consider your pet’s symptoms, physical examination findings, and any previous bloodwork, X-rays, or other diagnostic results.
2. Preparing your pet for imaging
A small area of fur over the abdomen is usually clipped to allow good contact between the ultrasound probe and the skin. Ultrasound gel is then applied to help produce clear images.
Depending on the reason for the examination, your veterinarian may recommend that your pet fast for a period beforehand. This allows your veterinarian to obtain better images of the liver, gallbladder, and stomach. Always follow the specific instructions provided by your veterinary team, and ask before withholding food from young, diabetic, or medically fragile pets.
3. Examining the abdominal organs
The veterinarian moves the probe over the abdomen to evaluate the relevant organs and structures. The examination may take approximately 20–30 minutes, depending on your pet’s condition and the complexity of the study.
4. Reviewing the findings and discussing next steps
The images are assessed alongside your pet’s symptoms and other test results. Depending on the findings, your veterinarian may recommend medication, additional laboratory tests, sampling of an abnormal area, referral for advanced imaging, or another treatment plan.
The goal is to use the information gathered to guide appropriate care for your pet.
What Diseases Can an Abdominal Ultrasound Detect in Dogs and Cats?
An abdominal ultrasound can help identify abnormalities associated with a wide range of conditions, including:
- Pancreatitis and other pancreatic abnormalities
- Liver disease and gallbladder disorders
- Kidney abnormalities, cysts, and certain urinary stones
- Bladder thickening, bladder masses and structural abnormalities
- Intestinal inflammation, wall thickening, and some foreign objects
- Abdominal masses and tumors
- Enlarged abdominal lymph nodes
- Free abdominal fluid and certain types of internal bleeding
- Certain reproductive tract abnormalities
- Structural changes associated with some chronic diseases
It is important to understand that an ultrasound does not identify every disease, and some conditions may appear normal on imaging. For example, microscopic disease, some early-stage conditions, and certain functional disorders may require bloodwork, urine testing, specialized laboratory tests, biopsies, or other diagnostic methods.
In many cases, abdominal ultrasound works best as part of a comprehensive diagnostic plan rather than as a standalone test.
When Should Your Pet Have an Abdominal Ultrasound?
Your veterinarian may recommend an abdominal ultrasound if your dog or cat experiences:
- Persistent or recurring vomiting or diarrhea
- Unexplained weight loss
- Decreased appetite or ongoing lethargy
- Abdominal pain or swelling
- Abnormal liver or kidney bloodwork
- Changes in urination
- Suspected pancreatitis
- A mass or enlarged organ identified during an examination or on X-rays
- Unexplained fluid in the abdomen
- Other symptoms that require a closer look at the abdominal organs
An ultrasound may also be recommended to monitor certain previously diagnosed conditions or help guide a sampling procedure.
An ultrasound can also be used as a screening tool for our senior dogs and cats. Older pets are prone to developing cancer. We can use abdominal ultrasound to help us detect certain cancers earlier before they are affecting the pet. Earlier detection means faster treatment and better prognosis.

Frequently Asked Questions About Pet Abdominal Ultrasound
Does my dog or cat need to be sedated for an abdominal ultrasound?
Most pets do not require sedation or anesthesia for an abdominal ultrasound. Some may benefit from mild sedation if they are anxious, uncomfortable, or unable to remain still. Your veterinary team will determine the safest and most appropriate option.
Does my pet need to fast before an ultrasound?
Fasting is commonly recommended before abdominal ultrasound because food and gas in the gastrointestinal tract can interfere with imaging. Instructions vary depending on your pet’s health and the reason for the examination, so follow your veterinarian’s directions.
How long does an abdominal ultrasound take?
Many examinations take approximately 20–30 minutes, although timing varies depending on the complexity of the case, the organs being evaluated, and your pet’s needs.
Can an abdominal ultrasound detect cancer in pets?
Ultrasound can identify masses and tissue changes that may be associated with cancer. However, imaging alone usually cannot confirm whether a mass is cancerous. Additional testing, such as cytology or biopsy, may be needed.
Is ultrasound better than X-rays for pets?
Neither test is universally better. X-rays are useful for evaluating the chest, bones, and certain abdominal abnormalities, while ultrasound provides detailed real-time images of many soft tissues and internal organs. Your veterinarian will recommend the most appropriate test based on your pet’s symptoms.
