Many dog owners wonder: Is trazodone or gabapentin better for anxiety in dogs? Both medications are commonly prescribed by veterinarians for anxiety, stress, travel, veterinary visits, thunderstorms, and other stressful situations. However, they work differently, have different side effect profiles, and may be better suited to different dogs.
Quick Answer
Is trazodone or gabapentin better for anxiety in dogs? There is no single winner. Trazodone is often chosen when veterinarians want stronger anti-anxiety effects, while gabapentin is frequently used when calming support and mild sedation are desired. In many cases, veterinarians use both medications together because they can complement each other when properly prescribed.
When Owners Commonly Ask This
Owners often compare trazodone and gabapentin when:
- Their veterinarian offers both medications as options
- Their dog has severe thunderstorm anxiety
- Travel causes extreme stress
- Their dog becomes anxious during veterinary visits
- One medication does not seem effective enough
- Side effects develop with a current medication
- They are wondering why their veterinarian prescribed both drugs together
If you’ve found yourself comparing these medications, you’re asking one of the most common questions in canine anxiety management.
What Is Trazodone?
Trazodone is a serotonin antagonist and reuptake inhibitor (SARI).
Veterinarians commonly prescribe it for:

Is Trazodone or Gabapentin Better for Anxiety in Dogs?
What Is Gabapentin?
Gabapentin was originally developed to manage seizures and nerve pain but is now commonly used in veterinary medicine for calming support and anxiety management.
Veterinarians may prescribe gabapentin for:
- Anxiety
- Travel stress
- Veterinary visits
- Noise sensitivity
- Post-surgical recovery
- Chronic pain with anxiety
Unlike trazodone, gabapentin works by affecting calcium channels within the nervous system, helping reduce nerve excitability and promoting relaxation.
