Canine ultrasounds play a crucial role in helping vets diagnose various health conditions in dogs. And when diagnosed early, these conditions can be treated more effectively, leading to better outcomes for the dogs. Today, our Fort Worth vets explain ultrasounds and the role they play in veterinary medicine.
What is an ultrasound?
Ultrasounds for dogs are a non-invasive diagnostic procedure that uses sound waves to create images of the internal organs and structures within a dog's body. It helps veterinarians to visualize and assess the health of organs, such as the heart, liver, kidneys, and reproductive system.
Ultrasounds work by bouncing high-frequency sound waves off internal organs and tissues to produce images. They can identify a variety of conditions, including pregnancy, tumors, organ abnormalities, and fluid accumulation.
Because veterinary ultrasounds don't use any radiation, they are considered very safe, even for pregnant dogs.
Why might my dog need an ultrasound?
Below, we'll list some of the reasons why your dog may benefit from an ultrasound.
Pregnancy
This is one of the most common reasons why a dog may need an ultrasound – puppy care. Ultrasounds can help determine the number of puppies and their size. They can also help ensure a healthy pregnancy via monitoring.
Signs your dog might be pregnant include changes in appetite, weight gain, nipple enlargement, and behavioral changes such as nesting or increased affection.
Detecting Foreign Objects
Ultrasounds allow veterinarians to identify and locate foreign objects, such as swallowed toys or bones, which may not be easily detectable through physical examination alone. Additionally, ultrasounds can help assess the extent of any potential damage caused by the foreign object.
Signs your dog may have swallowed something they shouldn't have include vomiting, gagging, drooling excessively, refusing to eat, or experiencing abdominal pain.
Heart Conditions
These images, known as echocardiograms, allow veterinarians to evaluate the structure and function of the heart, assisting them in detecting any abnormalities or conditions that may exist. They can provide useful information about blood flow and detect potential problems with the heart valves or chambers.
Coughing, difficulty breathing, fatigue, and a decreased tolerance for exercise are all signs your dog may have a heart condition.
Abnormal Blood or Urine Test Results
If your dog's blood or urine test results raise any concerns, your veterinarian may order an abdominal ultrasound. These ultrasounds enable the visualization of internal organs such as the liver, kidneys, spleen, lymph nodes, and urinary bladder to determine the source of the abnormalities.
Your dog may require an abdominal ultrasound if they experience unexplained weight loss, persistent vomiting or diarrhea, or changes in appetite.
Tumors
Ultrasounds can be used to detect tumors, though this is admittedly less common. These images can provide useful information about the tumor's size, location, and characteristics, allowing doctors to determine the best course of treatment.
Although the symptoms of a tumor can vary depending on its size and location, some common ones include unexplained weight loss, fatigue, swelling, and abnormal bleeding.
How can I prepare for my dog's ultrasound?
Fasting your dog prior to an ultrasound is typically recommended to ensure a clear image of the organs. It is recommended to fast them for at least 8-12 hours before the procedure. Furthermore, avoiding strenuous exercise can help prevent complications during the ultrasound examination.
Your dog will need to be calm and relaxed during the exam. While some dogs remain calm and cooperative, many others may require sedation. This is especially true for most young dogs and those who are nervous or have difficulty remaining calm in unfamiliar situations. Veterinarians can carefully evaluate each puppy or dog's behavior and determine whether sedation is required for a successful and stress-free ultrasound examination.
Finally, inform the veterinarian of any medications your dog is currently taking, especially if the ultrasound is performed outside of your primary veterinarian's office. They may have an effect on the ultrasound results or interact with the sedative.
