The usual dosage of dexamethasone for dogs varies based on the condition that’s being treated. For instance, treatment of inflammatory condition usually requires a dose of 0.1 to 0.3 mg per pound of body weight twice a day. As an immunosuppressant, on the other hand, the dosage is higher — usually 1 to 3 mg per pound up to three times a day.

A dog taking dexamethasone for mild inflammation typically only needs 0.1 mg to 0.3 mg per lb. When using dexamethasone to suppress a canine’s immune response, vets prescribe a higher dosage, generally 1 to 3 mg per lb.

The dose of dexamethasone varies depending on the reason for prescribing and the dose will be determined based on the disorder, severity of the condition, and the duration of therapy. Anti-inflammatory doses range from 0.1 to 0.3 mg per pound (0.2 to 0.5 mg/kg) up to twice daily.

The dose of dexamethasone for dogs varies in each case, because in emergencies vets may recommend a higher amount of the drug. Even so, the general rule is to administer between 0.1 and 2 milligrams per kilogram of weight of the animal.

DOGS - 0.25 to 1 mg intravenously as the initial dosage. (Based on 3 mg per mL of dexamethasone.) The dose may be repeated for three to five days or until a response is noted. HORSES - 2.5 to 5 mg intravenously. (Based on 3 mg per mL of dexamethasone.)
