What you should actually do
- Situational dose: 4-12 mg/kg, given 60-90 min before the trigger.
- Daily/chronic dose: 3-7 mg/kg every 8-24 hours.
- Higher fat content of the meal slightly delays peak effect (not clinically meaningful).
- Effect plateaus around hour 3 and tapers off across hours 6-12.
- Combine with gabapentin for vet/grooming visits if trazodone alone isn’t enough.
Trazodone is a SARI (serotonin antagonist + reuptake inhibitor) used in dogs for situational anxiety – storms, fireworks, vet visits, grooming, post-surgical crate confinement – and as a chronic adjunct for generalized anxiety. Onset is fast enough that one tablet 60-90 minutes before a fireworks display is a workable plan, but slow enough that giving it at the moment of the trigger is too late.
A practical trick from veterinary behaviorists: do a ‘practice’ dose at home on a calm day before you depend on it for a vet appointment. About 10% of dogs have a paradoxical excitement reaction, and you want to discover that on the couch, not in the waiting room. The biggest mistake owners make is giving trazodone too late and concluding ‘it doesn’t work’ – it does, but only if the drug is already in the dog before the cortisol spike from the trigger.
