Is Trazodone Addictive for Dogs?

Trazodone, an antidepressant primarily prescribed for humans, has made its way into the world of veterinary medicine. Dog owners and veterinarians alike have turned to this medication to treat behavioral issues in dogs, especially anxiety. But with its increasing use, many pet parents wonder: is trazodone addictive for dogs?

What is Trazodone?

Trazodone is a serotonin antagonist and reuptake inhibitor (SARI) primarily prescribed to treat depression in humans. However, it’s been recognized in the veterinary field for its potential to manage certain behavioral disorders in pets, notably anxiety.

Trazodone’s Popularity in Veterinary Medicine

Trazodone’s sedative effect makes it a favorable option for managing situational anxiety, like vet visits or thunderstorms. It’s also been used as an adjunct therapy for more chronic behavioral disorders, often in combination with behavioral modification strategies.

Is Trazodone Addictive for Dogs?

From the current scientific literature and anecdotal evidence, trazodone is not habit-forming in dogs. Unlike certain medications like Xanax (Alprazolam), trazodone doesn’t create a physical dependency. However, it’s crucial to understand that any medication, if misused or stopped abruptly, can have adverse effects.

Potential Side Effects

As with any medication, there are potential side effects, and pet parents should be aware:

  • Drowsiness or sedation
  • Incoordination or clumsiness
  • Gastrointestinal issues like diarrhea or vomiting
  • Increased or decreased heart rate

Proper Use and Weaning

While trazodone is not addictive, sudden cessation after prolonged use might lead to rebound anxiety or behavioral changes. Always consult with your veterinarian about the correct dosage and, if necessary, the proper way to wean your dog off the medication.

Natural Alternatives and Training

Relying solely on medications might not be the best approach. Combining trazodone with behavioral training, environmental adjustments, and natural remedies like pheromone collars or calming supplements can offer a holistic approach to managing your dog’s anxiety.


In the vast realm of veterinary medicine, trazodone emerges as a potential solution for situational and chronic anxiety in dogs. While it’s not deemed addictive, a responsible approach is always recommended. Stay informed, consult with professionals, and always prioritize the well-being of your furry friend.

FAQs on Trazodone for Dogs

Q1. How does Trazodone work in dogs?

Trazodone works by modulating serotonin levels in the brain, which plays a crucial role in mood and anxiety. By blocking the reuptake of serotonin, trazodone increases its availability, helping reduce anxiety and promote a sense of calm.

Q2. What is the recommended dosage for dogs?

The recommended dosage varies based on the dog’s weight, age, health status, and the severity of the condition being treated. Typical doses range from 3 to 5 mg/kg, but it’s essential to follow your veterinarian’s prescription to ensure your dog’s safety.

Q3. How long does it take for Trazodone to start working?

Most dogs experience the calming effects of trazodone within one to two hours of administration. The duration of its effectiveness can range from 4 to 8 hours, depending on the individual dog and the dose provided.

Q4. Can Trazodone be combined with other medications?

While trazodone can be used in conjunction with other drugs, such as SSRIs like fluoxetine, there’s a risk of serotonin syndrome – a potentially life-threatening condition caused by high serotonin levels. It’s imperative to consult with a veterinarian before combining medications.

Q5. What should I do if I miss giving a dose to my dog?

If you miss a dose, give it as soon as you remember. If it’s close to the next scheduled dose, skip the missed dose and continue with the regular schedule. Avoid giving a double dose.

Q6. Are there any long-term effects of using Trazodone in dogs?

While trazodone is considered safe for both short-term and extended use, there’s a potential for side effects like drowsiness, gastrointestinal disturbances, and, rarely, heart arrhythmias. Regular check-ups with your vet can help monitor any potential long-term effects.

Q7. How should Trazodone be stored?

Store trazodone in a cool, dry place, away from direct sunlight. Ensure it’s out of reach of children and pets. Do not store in damp places like bathrooms, as moisture can degrade the medication.

Q8. Are there any natural alternatives to Trazodone for dog anxiety?

Q9. Can Trazodone be used in cats or other pets?

While primarily discussed in the context of dogs, trazodone has also been used off-label in cats to treat similar behavioral issues. However, the dosage and potential effects might differ. Always consult with a veterinarian for species-specific advice.

Signs of a trazodone overdose include severe drowsiness, slowed breathing rate, tremors or seizures, and a decreased heart rate. If you suspect an overdose, seek emergency veterinary care immediately.

Q11. How should Trazodone be administered to dogs?

It’s best to follow your veterinarian’s guidance, but generally, trazodone is given orally, either with or without food. If the dog resists, consider using pill pockets or combining it with a small treat. Always ensure your dog has access to fresh water after administration.

Q12. Can a dog build a tolerance to Trazodone?

Tolerance refers to a decrease in response to a drug after prolonged use. While there’s no comprehensive study indicating that dogs develop tolerance to trazodone, it’s essential to adhere to the prescribed dosage and consult your vet if you notice reduced effectiveness.

Q13. Is Trazodone used for conditions other than anxiety in dogs?

Primarily, trazodone is prescribed for anxiety in dogs. However, its calming effects mean it might also be given before vet visits, during post-operative recovery, or to ease the stress of long trips.

Q14. Can Trazodone cause weight gain in dogs?

While weight gain isn’t a common side effect of trazodone itself, an increase in appetite could be observed in some dogs. If you notice a sudden change in your dog’s weight, consult with your veterinarian to rule out other potential causes.

Q21. What happens if I miss giving my dog a Trazodone dose?

Senior dogs may have slowed metabolism and reduced organ function, which can impact how they process medications. Trazodone dosages might need to be adjusted for older dogs, and they should be closely monitored for any adverse effects.
