Low dose dexamethasone suppression tests (LDDS tests) are a common diagnostic tool used by veterinarians in the US to diagnose Cushing’s disease (hyperadrenocorticism) in dogs. While generally safe, it’s important for dog owners to be aware of the potential low dose dexamethasone suppression test dogs side effects. This article will delve into the possible side effects, what to expect during and after the test, and when to contact your veterinarian.
Understanding the LDDS Test and Its Purpose
The LDDS test measures how your dog’s adrenal glands respond to dexamethasone, a synthetic steroid. It helps determine if the adrenal glands are overproducing cortisol, a hormone that plays a vital role in metabolism, stress response, and the immune system. An overproduction of cortisol is indicative of Cushing’s disease. While the test is essential for diagnosis, some dogs may experience side effects.
Common Low Dose Dexamethasone Suppression Test Dogs Side Effects
Most side effects associated with the LDDS test are mild and temporary. They can include:
- Increased thirst and urination: Dexamethasone can cause dogs to drink and urinate more frequently. This is usually temporary and resolves once the test is complete.
- Increased appetite: Some dogs may experience a temporary increase in hunger after the dexamethasone injection.
- Panting: Dexamethasone can sometimes cause panting, especially in warmer environments.
- Lethargy or restlessness: Some dogs might appear more tired or restless than usual.
- Mild gastrointestinal upset: In rare cases, some dogs may experience vomiting or diarrhea.
When to Contact Your Veterinarian
While mild side effects are common, contact your veterinarian immediately if your dog experiences:
- Severe vomiting or diarrhea
- Difficulty breathing
- Collapse or seizures
- Any other unusual or concerning symptoms
These could indicate a more serious reaction to the dexamethasone.
Managing Side Effects
Most side effects resolve on their own within 24 hours of the test. Ensure your dog has access to fresh water to address increased thirst. If your dog experiences gastrointestinal upset, your vet may recommend a bland diet for a short period. For panting, make sure your dog is in a cool, comfortable environment.
What to Expect During and After the LDDS Test
The LDDS test is a relatively simple procedure. Your veterinarian will take a blood sample before administering a small dose of dexamethasone via injection. Blood samples are then taken again at specific intervals (typically 4 and 8 hours after the injection) to measure cortisol levels. Your dog will need to stay at the clinic during this time. After the final blood draw, your dog can usually go home. Your veterinarian will discuss the results with you once they are available.

Alternative Diagnostic Tests for Cushing’s Disease
While the LDDS test is commonly used, other tests can help diagnose Cushing’s disease, including the ACTH stimulation test and urine cortisol:creatinine ratio. Your veterinarian will determine the most appropriate test based on your dog’s individual circumstances.
