Trazodone for Dogs: A Comprehensive Guide

Introduction

Trazodone is a serotonin antagonist and reuptake inhibitor (SARI) antidepressant medication commonly prescribed to humans but has also been used off-label in veterinary medicine to treat various conditions in dogs, primarily for its sedative and anxiolytic effects.

Uses of Trazodone in Dogs

Trazodone is primarily used in dogs for:

• Anxiety (e.g., noise phobia, separation anxiety, social anxiety)
• Sedation (e.g., for veterinary procedures, travel)
• Appetite stimulation (especially in older or underweight dogs)
• Aggression (in conjunction with other behavioral therapies)

Mechanism of Action

Trazodone's exact mechanism of action in dogs is not fully understood, but it is believed to work by blocking serotonin receptors in the brain, increasing serotonin levels, and regulating neurotransmitter activity.

Dosage and Administration

The dosage and frequency of trazodone administration in dogs vary depending on the individual's weight, condition, and response to the medication. The typical dosage range is 2.5-15 mg/kg every 8-24 hours. It is recommended to start with a low dose and gradually increase it as needed to achieve the desired effect while minimizing potential side effects.

Stories

Story 1:

Gizmo, a 7-year-old golden retriever, was struggling with severe separation anxiety, leaving him panting, pacing, and whining when left alone. His owner tried various calming aids and behavioral therapies without success. Upon consultation with their veterinarian, Gizmo was prescribed trazodone. Within a few days, Gizmo's anxiety significantly decreased, and he was able to spend time alone without distress.
