Dog Trazodone Dose Calculation Formula

The formula for calculating the trazodone dose for dogs is:

Dose (mg) = Weight (kg) × Dosage rate (mg/kg)

The typical dosage rate for trazodone in dogs ranges from 2.5 to 3.5 mg per kg of body weight.

• For a 20 kg dog at the lower dosage rate: Dose = 20 kg × 2.5 mg/kg = 50 mg
• For a 20 kg dog at the higher dosage rate: Dose = 20 kg × 3.5 mg/kg = 70 mg
