Trazodone for Dogs Dosage: How Vets Set It
You won't find a trazodone dosing chart here, and that's deliberate. The right dose depends on your dog, and getting it wrong isn't worth the shortcut.
The trazodone dose for dogs is weight-based and set by your veterinarian, who starts low and adjusts, so there is no safe fixed chart to follow at home. Vets recommend a test dose on a calm day before you rely on it for a real event. Never adjust the dose yourself.
About trazodone for dogs & cats: this is a prescription medication your veterinarian can prescribe. Read our guide, or ask us if you need help sourcing it.
Why we don't publish a dose-it-yourself chart
Trazodone is prescription-only, and the correct dose varies widely by the dog's weight, health, and what other medications it takes (some combinations are risky).2 A generic milligram chart invites over-sedation or dangerous interactions, and a fixed number is not always the answer because the right dose depends on the underlying dog. Our licensed veterinarians set the dose for your specific dog.
How vets approach it
Vets generally start at the low end and titrate up over several days to reduce side effects.1 For situational use, they advise a test dose on a quiet day, without the stressor, to see how quickly your dog calms, how long it lasts, and whether there are side effects, before you count on it for a vet visit or a fireworks night.
Timing beats the exact number
For a predictable event, trazodone is given about one to two hours beforehand; effects last roughly 3 to 12 hours.2 It can be given with or without food, though a little food can reduce nausea. If you miss a daily dose, do not double up; resume the normal schedule.
Getting the right dose

Frequently asked questions about trazodone for dogs dosage
What is the dosage of trazodone for dogs?
It's weight-based and set by your vet, who starts low and titrates up. Because the right amount depends on weight, health, other medications, and situational vs daily use, we don't publish a self-dosing chart — a vet calculates it safely.
When should I give my dog trazodone?
For a predictable stressful event, about one to two hours before it, so the medication is working when the trigger arrives. Effects last roughly 3 to 12 hours. Test the dose on a calm day first to see how your dog responds.
Can I give my dog trazodone every day?
Sometimes — for ongoing anxiety, vets may prescribe daily trazodone, and full effect can take a couple of weeks. That's a veterinary decision, and daily use works best combined with behavior modification.
