If you’ve ever watched your dog tremble during a thunderstorm or panic during a vet visit, you know how distressing canine anxiety can be—for both of you. In recent years, trazodone has gained popularity as a vet-prescribed solution for helping dogs stay calm. But when it comes to dosing—especially the 50mg trazodone tablet—many pet owners are left with questions. Is it safe? Is 50mg too much? How often should it be given?
In this guide, we’ll explore the proper dosage of 50mg trazodone for dogs, including its uses, safety, potential side effects, and key considerations. Whether your dog suffers from general anxiety, noise phobia, or post-surgical stress, this article will help you better understand how trazodone fits into their care plan.
What Is Trazodone and Why Is It Used in Dogs?
Trazodone is a prescription antidepressant that belongs to the class of serotonin antagonist and reuptake inhibitors (SARIs). Originally developed for humans, it’s now commonly used in veterinary medicine as an off-label medication to treat anxiety and behavioral disorders in dogs.
Common Uses in Dogs:
- Generalized anxiety
- Noise phobia (e.g., fireworks, thunderstorms)
- Separation anxiety
- Post-surgical calming
- Travel-related stress
- Aggression linked to fear or anxiety
Trazodone works by increasing serotonin levels in the brain, promoting a sense of calm and relaxation.
Is 50mg Trazodone Safe for Dogs?
Yes, 50mg trazodone is generally safe for dogs, but only when prescribed and dosed properly by a veterinarian. The appropriate dose depends on several factors, including your dog’s weight, age, overall health, and reason for use.
Factors Influencing Dosage:
- Dog’s weight
- Sensitivity to medications
- Underlying medical conditions
- Other medications your dog is taking
Never administer trazodone—or any medication—without veterinary guidance.
Recommended Trazodone Dosage for Dogs
Trazodone is typically dosed based on milligrams per kilogram (mg/kg) of body weight.
General Dosage Guidelines:
- 1.7 to 9 mg per pound (3.75 to 20 mg/kg) every 8 to 24 hours
- For example, a 30-pound dog might receive 50 to 100mg, depending on the condition and veterinarian’s recommendation.
Is 50mg a Normal Dose?
For small to medium dogs (15–30 pounds), a 50mg dose often falls within the appropriate range. For larger dogs, this dose may be considered mild or a starting point.
Always start with the lowest effective dose and monitor your dog’s response. The vet may adjust the dosage over time.
How to Give Trazodone to Your Dog
Trazodone is typically administered as an oral tablet. Here’s how to make the process smooth and stress-free:
Tips for Administration:
- Give with food to reduce the risk of stomach upset
- Hide the tablet in a pill pocket, cheese, or peanut butter
- Maintain a consistent schedule if used regularly
- Use as needed for situational anxiety (e.g., fireworks)
What to Expect After Giving 50mg Trazodone
Most dogs start to feel the effects within 30 to 90 minutes after administration. Effects may last between 4 to 12 hours, depending on your dog’s metabolism and dosage.
Signs It’s Working:
- Reduced pacing, trembling, or whining
- Calmer behavior during stress-inducing situations
- Improved ability to rest or sleep
Possible Side Effects of Trazodone in Dogs
Like all medications, trazodone may cause side effects, especially if the dosage isn’t properly tailored.
Common Side Effects:

- Panting or restlessness
Less Common but Serious Effects:
- Agitation or hyperactivity

If any serious symptoms occur, contact your veterinarian immediately.
Drug Interactions and Precautions
