Comment 15: “How is the Vetoryl dose determined for a dog?”

The dose of Vetoryl is typically determined based on the dog’s weight, severity of symptoms, and cortisol levels as assessed through blood tests. The initial dose is generally conservative, with regular monitoring (e.g., ACTH stimulation tests) conducted within 10-14 days to assess the effectiveness and adjust the dosage accordingly.

For dogs with a robust initial response, the vet may gradually increase or decrease the dose to achieve optimal results. Factors such as changes in appetite, thirst, urination, and energy are also taken into account when adjusting the dose. It’s important to avoid abrupt dosage changes without veterinary guidance, as this could lead to hormonal imbalances or complications like Addison’s disease.

Dosing FactorInfluence on DoseAdjustment Needed💡 Tip
